How will Mobile Operators Increase ARPU with Declining Voice Revenue?
Next Generation Value Added Services

Greg Tarr,
Partner CrossPacific Capital

Recent Fixed Pricing Plans from Leading U.S. Operators seem to spell the end for Voice Revenue Growth.

In this declining Voice Revenue Environment, the big question is how quickly can a combination of next generation value added services and advertising keep growing Mobile Operator Revenues and Profits.
The Global Value Added Services Market is forecast to hit $77B in 2011 with over $33B generated in Asia.

We will take a global view from Operators and Cutting Edge Silicon Valley Startups on new innovative services that will be launched in 2008 and 2009 in the Mobile Social Networking and Mobile Music Search areas.
This panel will discuss Mobile Data Services market size, market drivers, technical advancements and the challenges of deploying a winning business model.

Wireless Multimedia, Flawless Tele-Presence and the World-Wide-Wait

Lajos Hanzo,
University of Southampton

Following a period of spectacular growth, basic wireless services have reached a high penetration, although most subscribers still rely on voice and low-rate data communications. The provision of sophisticated multimedia “telepresence” and media sharing services requires a further quantum leap from the current state-of-the-art represented by the popular mobile telephone.

This research-oriented panel will speculate on the future directions of the broad field of wireless multimedia communications, with a view involving you as a fellow researcher in outlining a range of open problems for our research community to address.

Commencing with a brief historical perspective, the panelists will outline a range of challenges related to wireless multimedia communications. There is concern that “point, shoot & share-style” video communications may result in the “world-wide-wait” owing to the potentially excessive offered teletraffic since the wireless channel has to obey information-theoretic limits and operators discourage high utilization of upstream channels.

A substantial capacity extension is offered by the employment of sophisticated source and channel coding as well as multi-functional smart antennas, prominent among next-generation wireless enabling techniques. Unfortunately smart antennas fail to reach their full potential under realistic shadow-faded propagation conditions, unless cooperative base stations are employed. Alternatively, they have to be combined with HSDPA-style adaptive modulation and coding.

The cross-layer optimized next-generation adaptive modulation and coding assisted transceivers are expected to offer soft degradation in response to high demand, dropping throughput rather than dropping a call, by employing adaptive slot classification. Novel multiple access techniques, such as Spatial Division Multiple Access (SDMA) and Interleave Division Multiple Access (IDMA), also offer substantial throughput improvements, especially with the aid of transmit preprocessing at the Base Station (BS), provided that sufficiently accurate channel estimates can be provided by the mobile stations for the BS’s future down-link transmissions.

In addition to enhancing the air interface, effort is needed to integrate the diverse wireless access networks (cellular, WiMAX, WiFi, UWB) with each other and with the metropolitan optical backbone. The requirements include smooth vertical handoff, continuity of OAM&P (in particular, billing), and maintaining end-to-end quality of service (QoS).

Clearly, further quantum leaps are required, in order to avert the threat of the ”world-wide-wait” in the emerging wireless Internet.

As the Internet Takes to the Air, Do Mobile Revenues go Sky High?

Prof. Hamid Aghvami,
Centre for Telecommunications Research, King’s College London

The wired Internet has brought about a multitude of novel services and applications, such as online retailing, social networking, online dating, gambling, online auctioning, peer-to-peer applications, etc. These services and applications have generated billions of dollars revenue in recent years. The question is whether this paradigm of Internet success can be taken to the mobile domain. What will be the “killer applications” for mobile operators and service providers, and now will the success of the current wired Internet services and applications translate to the mobile domain? How can mobile operators offer these services efficiently and cost effectively to their customers? What are the optimal business models and the optimal splits of functionalities between application/service providers and mobile operators?

The panel session will attempt to address and answer such issues and questions.

WiMAX: What the Future Holds

Dr. Jeffrey Andrews, Assistant Professor, University of Texas at Austin
Dr. Arunabha Ghosh, Principal Member of Technical Staff, AT&T Labs

WiMAX has led the way for emerging cellular broadband standards, adopting an IP traffic model, OFDMA for modulation and multiple access, and accommodating MIMO to increase data rates. Was WiMAX ahead of its time? Will it be able to successfully compete domestically and internationally with the increasingly similar LTE and UMB standards? What further innovations are needed in WiMAX for it to deliver on its promises of cost-effective wireless broadband access? This panel will feature diverse experts engaged in WiMAX technical and business development.

Realizing QoS in WiMAX Networks: Business, Operational, and Technical Challenges
How Close are We to Reality?

Dr. Vishal Sharma, Metanoia, Inc.

With the worldwide interest in WiMAX deployment, 2008 is slated by many as the year of WiMAX. As deployments and rollouts begin, with both fixed and mobile WiMAX networks, the many QoS capabilities built into the WiMAX standard (and associated products/services) will start to be utilized and taxed, as WiMAX networks will carry a wide mix of enterprise-class and consumer-class traffic. In this environment, it will be crucial to assess how close we will be (and how soon) to the promise of realizing QoS for services offered in such networks, and what that will mean for service providers: operationally and in revenue terms.

The panelists will address the following:
- What business advantages do these capabilities provide to the operator?
- How may operators use these capabilities in offering new, revenue-generating services?
- What do the customers themselves desire -- in terms of quality and performance expectations? And, in terms of SLAs?
- Will tiered pricing models be practical? Which other pricing strategies can operators utilize to make these services attractive, yet profitable?
- What are the challenges of utilizing these capabilities? Practical, operational, and deployment?
- What is the state of progress in these areas in WiMAX deployments worldwide ˆ in Latin America, Russia, EMEA, Asia, Africa?
- Finally, how close are we to the reality of having "true" QoS in broadband wireless networks?
