Enterprise Network Architecture: A Users
Perspective
TECHNOLOGY PANEL
Organizer and Moderator: Merwyn Andrade, Aruba Wireless
Networks
Panel Summary:
This panel brings together users and vendors of WLAN technology
to discuss and debate the different approaches, technologies and
issues surrounding WLAN deployment within todays enterprise.
Panelists will examine issues such as adding value to or taking
value from access points, making WLANs as secure as their wireline
equivalents, Layer 2 and Layer 3 security mechanisms, role of
Information Technologies, WLAN scalability, centralized versus
distributed network management and control.
Panelist: Neil Buckley, Partners Healthcare
Wireless network security is a multi-faceted problem that cant
be solved by a single product. It includes protecting the traffic
with advanced encryption schemes, protecting the network with
sophisticated authentication and access control mechanisms and
protecting the users with polices and security that moves with
them. Enterprise today must wade through a sea of security standards
and approaches from WEP to TKIP to AES, Layer 3 tunneling technologies
such as IPsec to new authentication approaches such as 802.1X.
This presentation explores the wide range of wireless security
mechanisms, examining the various alternatives available as well
as the architectural pitfalls facing the network manager.
Panelist: Robert Sanchez, inCode
Deploying 802.11 networks on a large-scale is ridden with issues,
from costly site surveys to continual upgrades and how to operationally
manage thousands of access points. Many options exist today for
enterprises in deploying 802.11 WLANs but few provide the best
model for scaling and securing large-scale deployments. We examine
some of the technical, operational, deployment issues facing enterprises
installing Wi-Fi networks.
Panelist: Abner Germanow, IDC
Should enterprises centralize wireless intelligence or distribute
it? Should wireless users be quarantined behind a DMZ or just
attached to the Layer 2 corporate network with Layer 2 encryption
running across the link? What do I need to do about mobility and
mobile security? These are some of the questions that we address
in his presentation on 802.11 technologies. We detail the many
aspects of 802.11 technology standards are and discuss their implementations.

Wireless Networks Security
TECHNOLOGY PANEL
Organizer and Moderator:Leslie D. Owens (Les), Booz Allen
Hamilton
Panel Summary:
This panel explores the latest network security issues in the wireless
world. It is likely to be security lessons learned from 1G cellular
and 802.11 wireless LAN that can be applied to emerging technologies
such as 4G and mesh networks. Additionally, we will address the
latest in end-to-end application security over wireless, wireless
Public Key Infrastructure, wireless security crypto performance
and idiosyncrasies of intrusion detection for wireless..
Managing Data Security in the Mobile and Wired Enterprise
Panelist: George Heron, SafeNet, Inc.
Policy management has proven its worth in the wired industry. Within
the enterprise, remote users and their practices must be managed.
With the growth of more corporate mobile users, policy management
in a wireless world will ultimately need to be addressed. Other
issues will include the ways to combat the new set of security threats
that evolve with wireless communications including cloning, untrusted
code, lost/stolen devices, theft of content and denial of service.
This presentation will discuss the policy management needs for a
workforce on the road ... both classic and unconventional.
Bringing Secure Connectivity to Wireless Mobility
Panelist: E. Sanders Partee, Ecutel, Inc.
Enterprises are seeking the productivity boosts offered by wireless
connectivity, especially from Wi-Fi networks. However, the adoption
of such technologies is hampered not by cost, but by security concerns
and the increased complexity for workers to roam between networks
behind and beyond the corporate firewall. Access to corporate networks
has become increasingly cumbersome for the mobile worker as well
as a burden for IT departments. Whether providing access to the
network from a wired or wireless connection, security, connectivity,
support and maintenance are constant challenges for the enterprise.
Enterprise users of Wi-Fi networks are faced with the following
problems of Security and Integration with other networks. A devised
Solution is based on Mobility, Simplicity, and Security.

Ad Hoc Networks
TECHNOLOGY PANEL
Organizer and Moderator: Peter Stanforth, MeshNetworks
Panel Summary:
Proponents of ad hoc networking believe that it is a truly disruptive
technology that has potential to fundamentally change the way wireless
networks are designed and deployed. The concept has been under investigation
and development since the DARPA packet radio experiments 20 years
ago, but it has only recently graduated from the lab into commercial
products. Ad hoc networking (or mesh networking as it is commonly
known) is beginning to appear in products for 802.11, last-mile
and mobile broadband applications from both start-up and established
vendors. Find out why this technology is being called the next major
step forward for wireless network design.
In this session industry experts will provide an in depth look at
the technology and it's present day application to various segments
in the wireless industry. Benefits of ad hoc networking, including
self-forming and self-healing routing, spectral efficiency and organic
scalability will also be highlighted. Market potential for ad hoc
networks, as well as some of the unique applications that can be
addressed by the technology will be presented. Finally a review
of the ad hoc networking efforts within the IEEE standards bodies
will give an up-to-date view on the issues being tackled in preparation
for wide spread adoption of this technology.
Panelist: Scott Corson, Flarion
There will be a brief presentation on the current status and likely
direction of IETF standards work on ad hoc network routing work
underway in the IETF's Mobile Ad hoc Networks (MANET) Working Group.
This will be followed by a critical look at the pros and cons of
ad hoc networking as a technology relative to more traditional base
station-oriented wireless network access technologies.
Panelist: David Robak, Cybiko, Inc
We present the application of ad hoc peer to peer networking implementation
in mobile devices. We discuss startling revelations and techniques
used within the wireless PDA teen space and the migration to mass-market
implementation in cellular phones. We present the defining characteristics
that change this technology from a differentiating application to
an essential disruptive technology in the distribution of protected
digital content.
Panelist:
Richard D. Dwelle, NexGen City
Ad hoc peer-to-peer wireless networks inherently solve current issues
in public safety communications. Communication interoperability,
self forming/self healing networks, device location and increased
data rates are just a few of the added functionality these networks
provide to first responders. This presentation discusses how ad
hoc peer-to-peer wireless networks will play a significant role
in the future of public safety communication.

Software
Defined Radio An Implementation Perspective
TECHNOLOGY PANEL
Organizer and Moderator: Stephen M. Blust, Cingular Wireless
Panel Summary:
Software Defined Radio is beyond the education and initiation phase.
The industry is addressing the needs of reconfigurable radio technology
development, implementation, and application in a variety of marketplaces.
Regulatory decisions are being formulated to facilitate SDR adoption
and deployment. This panel discussion will bring together representatives
of the wireless value chain, including core technology/component
suppliers, radio software developers, terminal manufacturers, infrastructure
manufacturers, wireless operators/service providers, and regulators
to discuss the implementation of SDR and provide a top to bottom
perspective.
Panelist: James A. Hoffmeyer, Panasonic
There are numerous different perspectives of software defined radio
and its applications. In this presentation, the perspective will
be that of software download to SDR-enabled devices. This perspective
includes the value of software download to users, service providers
and manufacturers. The SDR Forum has initiated an aggressive program
in developing requirements for radio software download. The Open
Mobile Alliance has defined use cases for radio software download
as well as content or applications software download. The presentation
provides information regarding both the SDR Forum and OMA work efforts.
Panelist: Louis Luneau, Radical Horizon
We discuss the radio computing concept based on an open standards
architecture utilizing SDR technology and how SDR changes the traditional
value chain. A wireless base station example is used to show the
application readiness and limitations that exist today.

The Business and Technical Case for Wireless Sensor
Networks:
Is Homeland Security the Killer App?
TECHNOLOGY
PANEL
Organizer and Moderator: Reginald Brothers (moderator), Draper
Laboratory; Kathy Sohrabi, Sensoria Corporation
Panel Summary:
The vision of a world of massively proliferated embedded sensors
in large-scale networks that may be heterogeneous in sensing modality
and hierarchical in topology is frequently discussed. This vision
promises near ubiquitous virtual presence and implies seamless connectivity
to existing networked infrastructure. In spite of successful ongoing
military efforts in this field, very few, if any commercial and/or
large scale distributed wireless sensor systems are currently deployed.
We postulate this slow pace of technology emergence is due in most
part to two factors: lack of specific commercial applications with
a clearly defined business model and unavailability of enabling
technological capability. This panel discusses potential applications
and market and technological challenges to the actual implementation
and deployment of these systems.
Panelist: T. P. Smith, III, Science Applications International
Corporation
Wireless sensor networks are a new technological thrust in the long
history of human sensory extension. They are being designed for
biological, chemical, seismic, acoustic, infrared, telematic and
other applications. Sensors range from simple video cameras to silicon
micro- and nano-structures, hyper-spectral optical sensors and sophisticated
scientific instruments. The technical and scientific challenges
fall into three broad categories: the physics and engineering of
the sensors themselves; the development of robust, secure, ad-hoc
networks to deliver the data to the users; and the signal processing,
data fusion, and information processing required to detect and identify
specific agents, events and phenomena. The business challenges center
on cost, performance and return on investment. We will review the
state of the art using specific examples and outline the technical
and market challenges that lie ahead.
Panelist: G. Noubir, Northeastern University
We address the problem of securing wireless sensor networks. We
explain why traditional network security techniques cannot be applied
in a straightforward manner to wireless sensor network.. We describe
the inherent limitations of these wireless networks (energy, computation,
bandwidth, channel unreliability, and mobility) and show how they
impact security services. We discuss the obstacles facing the development
of traditional security services: authentication, confidentiality,
and integrity. We also discuss more elaborate security services
such as secure group communication, multilayer denial of service,
anonymous routing, and fairness enforcement.
Panelist:
Sanjeev R. Kulkarni, Princeton University
The
possibility of deploying a large number of networked sensors presents
great opportunities for a host of commercial, military, and homeland
security applications, but also presents enormous technical challenges.
We argue that a mismatch between technology and expectations is
the limiting factor in the deployment of wireless sensor networks.
In particular, in most applications one of key benefits of deploying
a sensor network would be to aid in high-level decision-making.
Yet, this is also a notoriously complex task. In addition to wireless
network issues, sensor networks must do a great deal more than just
support communication. Transporting bits does not automatically
lead to intelligent decision-making, and connectivity does not automatically
result in coordination. In a sensor network there is a joint purpose
to be accomplished by the network as a whole. There are fundamental
questions about what information to transmit, where to send it,
how to utilize it, and whether to do computations locally, or to
pass information to higher layers for centralized computations.
These tasks must be accomplished in the face of scarce resources,
notably limited time, bandwidth, and power.
Thus, it is not surprising that at such an early stage, relatively
little progress has been made in this regard.

The Internet Technology Model Impact Within Wireless
Networks
TECHNOLOGY PANEL
Organizer and Moderator: Iain Gillott (moderator), iGillott
Research; Gail Redmond, Telespree Communications;
Jack Newton, Calysto Communications
Panel Summary:
Internet technologies are increasingly being incorporated into wireless
networks. Protocols and programming languages that originate from
the Internet world, such as WSDL, XML, WAP and MIP, are being used
to create new (and improved) wireless activation technologies. This
panel explores new ways that the Internet model is encroaching upon
wireless and how this is likely to affect wireless network performance
and market trends in the future. Specific topics to be discussed
include: The emergence of new device-network relational technology
that is similar to Dynamic Host Configuration Protocol (DHCP) in
the IP world and that enhances complicated wireless activation processes
today (e.g. OTASP). The impact of the web services model: what opportunities
are created to automate account set-up and provisioning? And, the
potential positive economic impact of such technology on wireless
network operations and applications such as telemetry and gaming.
Panelist: Toshio Miki, DoCoMo USA Labs
We address frontier technologies and challenges related to enabling
innovative applications for the next
generation mobile networks. Internet technology for support of mobile
communications, mobility management
and security are among fundamental problems at hand. In this panel
discussion
we address these issues as well as their status in corresponding
IETF WGs. We also address
the impact of Fast handoff for Mobile IP (FMIP) on cellular networks.
Panelist: : John Major, Technology Solutions Group
The Implications of Automated Activation, Deactivation and Diagnostics:
There are vastly more machines that need to communicate with machines
and people than there are people to communicate with people or machines.
Even so, already, there's a developing need for off network self-coordinating
networks to reduce overall costs. Must there be networks within
networks? Part of this is driven by network activation costs that
are prohibitively high as a result of being still largely manual.
Internet/IP technology makes this possible. The implications are
enormous.
Panelist: :Alon Segal, Telespree Communications
Today Internet/IP-based technology is increasingly being incorporated
into wireless networks, IP-based technologies are creating more
than just new transport methods. Using the concept of customer acquisition
as an example, carriers can use auto-activating wireless devices
to create an effective one-to-one customer engagement - without
spending a fortune to do so. Inserting intelligence, similar to
Dynamic Host Control Protocol (DHCP), into the wireless activation
process enables carriers to use wireless devices as the point of
sale to interact with the buyer on a more personalized level and
thus offer targeted rate plans and features that best fit their
lifestyle.

Security and Privacy Implications of Wireless LANs
TECHNOLOGY PANEL
Organizer and Moderator: Satyendra Yadav, Intel Corporation
Panel Summary:
Wireless networks promise mobile networking environments with
potentially great productivity gains at lower cost. While wireless
networking has great potential in a number of applications, there
are significant security issues to be addressed. This panel explores
fundamental issues in securing wireless local area networks (WLANs)
from many perspectives e.g. standards, business, marketing, research
and applications.
Security and Privacy Requirements for Wireless LAN
Panel Moderator: Satyendra Yadav, Intel Corporation
Industry standards (such as IEEE 802.11) and product implementations
have been focused on ensuring authentication, access control,
and transmission security in Wireless LANs (WLAN). There are many
other aspects of securing a WLAN such as availability, survivability,
intrusion detection, and user privacy. This presentation will
discuss overall security and privacy requirements for WLAN and
describe the gaps in standards and current technology that need
to be filled to make the WLAN suitable for large scale deployment.
Securing WLANS with Location-Based Intrusion Detection
Panelist: Michael Maggio, Newbury Networks
In a traditional wired network, every device accesses the network
through a designated port. In a Wireless LAN (WLAN) it is difficult
to determine where the user is. To secure a WLAN we need to answer
not only who is accessing the network but also where
is it being accessed from. This presentation will discuss the
challenges facing information technology professionals with WLAN
security and detail alternative methods and practices for facing
these challenges head on. Location-enabled networks can deliver
a higher level of functionality for securing a WLAN with real-time
monitoring and location based intrusion detection for pinpointing
strangers and trouble spots on WLAN environments.
Edge Access Security
Panelist: Laszlo Elteto, Rainbow Technologies
RF networks (such as 802.11 networks) create security vulnerabilities
that can not be solved by protocol protection alone. We also need
to deal with the issues such as RF interference or jamming, networking
bandwidth starvation, and roaming. This presentation describes
security needs of Wireless LANs that are not covered by standards
such as 802.1x and 802.11i. The presentation will point out that
protocol security is only one component of providing complete
WLAN security.
Edge Access Security
Panelist: Paul Congdon, Hewlett-Packard Company
Effectively securing the edge of mobile networks represents one of the greatest barriers for large scale Wireless LAN deployment. Understanding the intricate details of todayís security solutions and how they can or can not support roaming and connection persistence in a mobile network is a daunting task for IT and network managers. This presentation will discuss alternative technologies used for providing secure authenticated network access in mobile networks. We will discuss pros and cons of authentication technologies such as 802.1X and VPN. How these technologies impact roaming, connection persistence and real-time applications will be reviewed. A forward-looking analysis of the needs for mobile network access will also be provided.

From 3G to 4G, From Technology to Market
TECHNOLOGY PANEL
Organizer and Moderator: Roberto Saracco, Telecom Italia
Labs
Panel Summary:
3G, in various shapes and shades is finally on the way. Somebody,
however, is starting to wander what is the real difference from
the 2G and 2.5G. The issue is not a technology one. It is quite
clear from a technological point of view what the differences are.
The issue is on the market. Do we have a significantly different
market for the 3G? What are the services that will make 3G a success
and were not delivered by 2.xG? This panel aims at discussing technology
from the point of view of market. What are the services that market
would be willing to pay for and that are not possible because of
3G technology? Is it something that makes multibillion $ investment
appealing? If the current experience in the transition from 2G to
3G is any indication, bandwidth alone is not playing a significant
role in the market pull. Moving onto 4G just to provide higher bandwidth
may not be the way to go. At the same time we know that technology
is going to evolve, even in the absence of a market pull. What would
be feasible in a 5-10 years time frame from a technological point
of view?
Title: 3G/4G Services
Panelist: Roberto Parodi, Ritsumeikan University
The strategic positioning of the wireless operator now is concerned
with the main issues of strengthening the core business (voice)
and developing the demand for new value added services. This is
reinforced by the fact that high data users (active data services
users and advanced data services users) are at the same time also
the higher voice spenders. In order to look forward to the UMTS
business cycle, it is important to capitalize the lessons coming
from 2,5 G and M -Services. In TIM, M-Services and MMS in particular,
have been fundamental applications that have made Value Added Services
ARPU grow after the launch of GPRS. This has been highly affected
by the effort of the entire wireless community (operators and manufacturers),
that have come up with a common technology platform. This is what
has been done in GSM Association with the definition of the M -
services standards. In this way, the challenge for the Operator in the future is to
ensure full interoperability and to play the centric role of brokering
with the other players positioned along the wireless value chain,
in a context where applications, interaction modes and middleware
are becoming more and more important to control the End to End communication
. From the end user perspective, the 3G approach of the operator
is to introduce a new paradigm of wireless services, that is to
say not only provide customer with a cellular service (technology
paradigm) but mainly with a personal service, in which the personalization
and the media component become crucial. Finally, we believe that
applications for the corporate segments will drive initially the
development of the new generation markets
Title: Mobile Multimedia Metropolitan Area Network for Wireless
VPN Services
Panelist: Gaute Lambertsen, Ritsumeikan University
One of the important challenges of next generation networks
will be to offer an omnipresent working environment to business
users, by offering Wireless Virtual Private Network (VPN) solutions
wherever the user goes. We believe that there is a large market
for this service, as this could give the edge to business users
on the move. The initial focus should however be business users,
as the price tag probably would be too high for private users during
the initial phases. We propose a Mobile Multimedia Metropolitan
Area Network (MM-MAN) as one viable 4G-network candidate since this
service will initially have to be deployed in metropolitan areas
where there are a lot of potential users. To offer the necessary
high data transmission speeds, micro-cells must be adapted, offering
challenges in supporting user mobility and in keeping the user connected
to the network upon rapid change of access point. Also, terminals
moving at different speeds would require different processing characteristics.
Business usages in wireless networks require a high level of security.
In addition to encrypting transmitted information, the addresses
of the users should also remain confidential to prevent monitoring
of the users actions. From an infrastructure viewpoint we feel that
the mobile access needs to be integrated with an All IP Passive
Optical Network within each MAN. This ensures high throughput and
dissemination of wireless access points. This Wireless VPN service
and its characteristics are felt to be one of the motivational factors
to invest in the evolution from 3G to 4G.
Title: Autodesk Location Services
Panelist: Eli Rosner, Autodesk Inc.
An interesting topic since we see challenges in both technology and market areas. Here are some of the areas where improvement can help boost Location Based Services, LBS. Some areas can be improved in 3G networks while others may be faster to implement once standards are more available and stable ‚ but is it 4G that will make it happen?
- Market education ‚ subscribers need to be educated about the possibilities exposed by LBS applications. I just returned from GSM in Cannes and I have not seen subscribers using LBS applications.
- Business models not clear ‚ the value chain for LBS has not settled down yet. There are still too many moving parts, which causes the wireless operator a major headache when they want to launch a service.
- Creation of Open Mobile Alliance (OMA) and inclusion of many available standards under that umbrella could lead to longer cycles.
- Location is a horizontal enabler and should be discussed as such. It adds value to existing applications and enhances use of SMS, IM and MMS.
- Location technology is only one obstacle that could be resolved in 4G but can partially be resolved even with 3G. Various applications have different accuracy and yield (ability to obtain location fix ‚ success rate) demands to add value. Applications categories in discussion are: Information services, Navigation, Field Force Automation, Transport (Taxi), Child tracking, medical alert.
- Service creation environment ‚ in a nascent market it is important to provide a service creation environment that enables application developers to rapidly develop applications. It allows experimentation with various services without a major investment.
- Privacy is a topic that needs to be addressed but it is not the showstopper for LBS applications.
- Roaming of location information and subscriberís data are important especially in countries that use the same communications standards (GSM for example)
- Location Enabling Servers (LES) are now the hot discussion topic in standard groups. Once the market matures the definition of the LES will become clearer and companies would be able to clearly articulate where they fit.

Ultra-wideband (UWB) An overview of the IEEE
802.15 Call For Proposals
TECHNOLOGY PANEL
Organizers: Fujio Watanabe, DoCoMo USA Labs, Ian Gifford
(moderator), XtremeSpectrum
Panel Summary:
This technology panel will focus on ultra-wideband (UWB) and the
current status from the preceding weeks IEEE 802 Plenary Meeting
and the initial round of Physical Layer proposals received on the
IEEE 802.15 Call For Proposals; most of which are based on UWB.
The attendees will be provided a short overview and summary of the
IEEE 802.15 Task Group 3/3a and their UWB studies to date. The Panel
will then discuss the UWB proposals, address various UWB schemes,
their addressability to the call and/or the emerging regulatory
framework, next steps, Project 802.15.3a timeline, etc. Additionally,
we will briefly overview the latest worldwide standards and regulatory
activities.
Panelist: Bob Huang, Sony Electronics
The ultra-wideband (UWB) communications promise of high bandwidth
and low power consumption at low cost is very attractive to consumer
electronics and PC industries. However, the lowest possible cost
can only be reached through the volume associated with worldwide
UWB deployment. Currently, UWB has regulatory approval only in the
United States. Frequency sharing studies which will serve as the
foundation of UWB regulations are underway in Europe. This session
will discuss the European regulatory process and give the current
status.
Panelist : Jeff R. Foerster, Intel
Intel has been researching and developing ultra-wideband (UWB) technology
for high-rate, short-range cable replacement applications like USB
2.0 for the last 2-3 years. The FCC allocation of 7.5 GHz of unlicensed
spectrum in 2002 presents a huge opportunity for the industry, but
also carries with it a big responsibility to properly share that
spectrum. As a result, industry standards become critical for enabling
this new technology to ensure widespread adoption and peaceful coexistence
with other narrowband systems. In this panel session, I will share
Intel's interest in UWB technology from the applications perspective,
a technical approach that achieves very high rates with inherent
flexibility for coexistence and future scalability, and our desire
and efforts to help the industry converge to a single standard.
Panelist: John McCorkle, XtremeSpectrum, Inc.
XtremeSpectrum is the leading provider of ultra-wideband (UWB) semiconductor
solutions for the wireless distribution of digital video and audio.
In this panel session, I will share XSIs interest in UWB technology
from an IEEE consensus standards point of view. XSI has been participating
in the IEEE 802.15 study group for over a year and the recent approval
of Project 802.15.3a and the subsequent Call For Proposal has created
a large field of candidate radio transmission technologies to be
considered for the new 802.15.3 Alternate Physical Layer. It is
anticipated that the majority of these proposals will based on UWB
Technology. We will provide an overview of our candidate proposal
and our desire and efforts to help the industry converge to a single
consensus standard.
Panelist: : Ryuji Kohno, Div of Physics, Electrical &
Computer Eng, Yokohama National University, Japan
Ultra-wideband (UWB) or impulse radio for commercial communication
applications is a recent innovation. The technology has many advantages
which stem from its UWB nature. It not only experiences significantly
less fading margins as reported recently, it can also penetrate
walls, offers extremely fine time-resolution and the possibility
of achieving processing gains much larger than those of typical
direct-sequence spread-spectrum communication systems. Many challenges
of UWB deployment include regulatory issues and, in particular,
co-existence and interference-related issues with GPS receivers.
Potential applications include wireless local area networks (LAN),
medical information distribution systems, entertainment systems,
ranging devices and multiple-access communication systems for short-range
or indoor applications. In addition, an overview of the Communication
Research Laboratory (CRL) project on UWB R&D will be introduced.
This project focuses on total R&D of UWB wireless communication
systems including devices, systems and regulatory issues in the
range of microwave (3-30GHz) and millimeter-wave (over 30GHz) in
order to pursue standardization and business with UWB four years
later.

3G - Opportunities for Customers, Applications/Infrastructure
Providers and Carriers
BUSINESS APPLICATIONS SESSION
Organizer and Moderator: Gennady Sirota, Starent Networks
Corporation
Panel Summary:
As mobile wireless carriers continue to deploy next generation networks,
they must identify new and unique services that will increase network
utilization and drive profitability. It has become clear that such
services must conform to the mobile subscribers lifestyle
and the mobile communications environment. As a result, next generation
services must provide greater flexibility for the subscriber to
communicate on their own terms, be it voice, data or an integration
of both. This panel provides an overview of 3G technologies, opportunities
for customers and application/infrastructure providers. Panelists
will discuss the following issues: delivering differentiated customer
services; enhancing the back-end billing process and capabilities
(reverse billing, destination billing, etc.); leveraging 3G to provide
enhanced carrier services; knowledge is power: channeling
enhanced customer visibility to offer tailored services (from applications
to billing); the state of 3G in North and South America, Europe,
and Pacific Asia.
Panelist: Gennady Sirota, Starent Networks Corporation
This presentation will provide a look at next generation voice and
data service opportunities provided by new, powerful networking
solutions. Such services include voice/data instant messaging, Push-to-talk
and voice web access providing a cost effective and compelling
service offering. These services will enhance the subscribers ability
to communicate, while positively impacting the wireless carriers
ability to increase revenue and profitability on 2G, 3G and future
networks.
Panelist: DeWayne Nelon, LogicaCMG North America
Speculation regarding the growth of the wireless data and multimedia
messaging markets in North America is addressed. We discuss the
facets that need to align in order to ensure success in next generation
applications upgraded networks, handset availability/adoption,
appealing content and greater consumer understanding of how to effectively
use the services. We also explore the significant revenue potential
from multimedia messaging once true carrier interoperability is
achieved. We discuss the areas where compelling content is at the
greatest demand - information services, entertainment services,
mobile banking, location-based services and m-commerce
Panelist: : Jon Auerbach, Highland Capital Partners
The hype of 3G is over. Saddled with debt, global wireless carriers
have scaled back their ambitions. Carriers are now realizing that
their key to survival and prosperity is not simply the size and
scale of the network, but rather the services that are carried through
the network. Forced to innovate, a handful of carriers have developed
compelling services that are driving significant revenue. 3G, meanwhile,
is morphing into an important technology add-on that can enhance
key areas of networks, providing better coverage and capacity. We
focus on how the shift in strategy help carriers and equipment vendors
provide solutions and drive revenue. The discussion will center
on opportunities over the next several years, and why the wireless
industry is poised to come out of the recent downturn stronger and
more nimble than ever.

Key Technologies Enabling Success of Wi-Fi Public
Access Networks
TECHNOLOGY PANEL
Organizer and Moderator: Jesse Frankel, Neo5 Wireless
Panel Summary:
The promise of ubiquitous wireless broadband access based on Wi-Fi
technologies is extremely compelling. As the business models evolve,
key developments across the technology landscape must converge
to enable mainstream acceptance and the ultimate success of public
access Wi-Fi networking. Improvements are needed in client computer
ease of use and in high performance multi-band Wi-Fi integration;
reductions in cost, complexity and manageability of network infrastructure
deployment; higher silicon level integration to enable wider range
of application-specific devices; creation of a global standard
for secure inter-network roaming. We probe these issues in depth
to explore the state of the technology curve that is driving the
Wi-Fi revolution in wireless communications.
Inter-Network Roaming
Panelist: Phil Belanger, Pass-One Association
Wi-Fi is being built into many devices; privacy and authentication
solutions have been standardized; coverage has been improved due
to new Wi-Fi infrastructure technologies; many of the billing
techniques used in mobile telephony can be applied to Wi-Fi. Even
the technical issues of Inter-Network Roaming have largely been
worked out. However we are in a vicious cycle now: usage of WiFi
is low due to lack of ubiquity and absence of global reachability;
meantime service providers do not invest in the infrastructure
to expand the Wi-Fi footprint due to insufficient usage. We explore
a way to break out of this cycle by establishing a global Wi-Fi
zone, i.e. a seamless roaming mechanism amongst all of the current
Wi-Fi providers.
WLAN Chip Sets and Silicon Integration
Panelist: Paul Struhsaker, Texas Instruments Corporation
With the tremendous growth in the size of the market, the number
of different applications, and the use of emerging 802.11 standards
for modulation, security, and QoS, we are beginning to see a new
generation of WLAN products that are differentiated by application
/ market segment. The presentation will review the trends in silicon
integration and radio technology from both a market and a technology
viewpoint. Emerging 802.11 enhancements will be reviewed which
impact design choices for integration moving forward.
High performance client computer integration of multi-band Wi-Fi
RF devices
Panelist: Liam Quinn, Dell Computer Corporation
WLAN
technology is now highly integrated into standard computing platforms,
such as notebook computers and PDAs. While availability of Wi-Fi
equipped computing systems has increased, the user experience
using public access Wi-Fi networks is still potentially challenging.
We address hardware and software integration improvements and
measures to improve over-all performance, e.g. support for multiple
RF modes (802.11b, Bluetooth), optimization of the radio/antenna
subsystem, antenna diversity for receive and transmit, software
tools to improve management of RF network connections, etc.
WLAN Infrastructure Technology and Trends- Not Just an Access
Point Anymore
Panelist: Jim Thompson, Vivato
WLAN
network design methodology using standard access point devices
has matured. However, technical and business challenges are presented
when trying to illuminate public access spaces with the standard
architecture of switched Ethernet cable plant and access points.
Multi-mode networks (802.11 a/b/g) require increased access point
density for consistent coverage. Also, implementing dynamic frequency
re-use schemes to maximize available capacity is difficult to
achieve with the current access point devices. We address next
generation RF distribution architectures that will offer alternative
mechanisms for deploying WLAN infrastructure in public spaces.
Managing User Identity Credentials and Data Protection
Panelist: Tony Fascenda, Koolspan LLC
In addition
to solving the technical issues required to enable public access
networks to support roaming, there remains another class of issues
related to reliable user identity credentials and the safe transmission
of identity information and account membership status over the
WLAN infrastructure. As more devices become Wi-Fi enabled, new
mechanisms are required to allow an owner of a collection of Wi-Fi
devices to uniquely identify him/herself to achieve smooth connection
to an ambient public access Wi-Fi network. Various deficiencies
in current WLAN transmission security schemes are being addressed
by a myriad of techniques, which may soon converge into a common
set of tools.

Spectrum Management for Mobile Technologies of
the Future
TECHNOLOGY PANEL
Organizer and Moderator: Murray Milner (moderator), Mansoor
Shafi, Telecom New Zealand
Panel Summary:
The early 21st Century represents a time of considerable change
for the mobile telecommunications industry. Developments in technology
are enabling wireless networks to offer a range of services that
in regulatory terms encompass the boundaries of fixed, mobile
and broadcasting . Is the current manner of spectrum allocation
by specifying the use still valid ?. Regulation changes are seldom
revolutionary, however, in today's fiercely market dominated environment
a "rapid regulatory response" to technological change
is required and this itself may be considered revolutionary. In
whichever manner spectrum management methods develop, it is during
this the transition period that complications will be most apparent.
The transition period represents a time when possibly dated methods,
such as licensing by application and grant, will co-exist with
newer methods, such as dynamic allocation of spectrum access rights,
or shared spectrum access.
A View from Europe
Panelist: Reiner Liebler, PTT, Germany
The presentation gives an overview on present challenges for spectrum
management in Germany and in Europe. We present a new approach
to a digital VHF/UHF broadcasting plan for Europe
and Africa (ITU Region 1) being sufficiently flexible for convergence
of services, address methods for co-ordination between UMTS/IMT-2000
networks in Europe and possible future developments, address ideas
and first conclusions on how to manage ultra wide band applications
and general aspects of spectrum trading and refarming with regard
to the future role of a spectrum management authority.
A View From USA
Panelist: Richard B. Engelman, International Bureau, Federal
Communications Commission
The issues of efficient spectrum management receive attention
by the US regulatory body. This presentation provides a US perspective.
A View From Brazil
Panelist: João Carlos Fagundes Albernaz, National
Telecommunications Agency Anatel
We present a Brazilian view on the spectrum management and also
will provide comments on the perspectives of other Latin American
countries
A View From Japan
Panelist: Kohei Satoh, Association of Radio Industries
and Business (ARIB), Japan.
Japan is facing an unprecedented growth in mobile services. We
describe the Japanese views on technologies for efficient utilization
of frequency based on Japanese Telecommunications Council's Report
. We also address the activities in ITU-R/WP8F on spectrum issues
for future mobile communications, e.g. spectrum sharing, frequency
arrangements, methodology for interference evaluation, etc.
