Testing Voice as Cellular and Wi-Fi Technologies Converge
(WM-01)
Thursday - 01/25/07, 8:30-9:15am
If you doubt that WiFi and cellular technology are on the brink of convergence, take a look at the recent proliferation of new products and industry groups. WiFi and enterprise voice vendors have a variety of voice-optimized WiFi equipment, and SOHO VoIP players deliver residential-optimized WiFi handsets to their users. Now the cell phone vendors have followed suit, releasing WiFi-enabled mobile handsets.
The key to successful WiFi to cellular roaming is the smooth hand-off as users roam between cellular and WiFi networks. Voice is a demanding application — it requires QoS and limits on delay, jitter and packet loss. And a high volume of WiFi enabled phones will place unprecedented traffic loads on WLANs, which will also need to support additional levels of security and equipment from a variety of vendors.
This presentation will examine the specific performance requirements for supporting WiFi to cellular roaming, including the requirements for VoWLANs. It will also review new protocols and standards initiatives for VoWLANs.

Content Delivery in the All-IP Wireless Network
(WM-02)
Thursday - 01/25/07, 9:15-10:00am
Based upon the economies of IP networks and the clear direction of mobile standards, it is clear that an all-IP mobile network is inevitable. In this all-IP network, multimedia applications such as streaming media are getting a lot of attention with more and more mobile users, and intelligent devices emerging every day. The mobile industry is focused on innovations with rich applications around images, games, chat and other forms of messaging. Mobile Operators have the daunting task of filling out their bundle of services (voice, video, data) and rapidly deploying competitive new applications while simultaneously minimizing cost. The ideal approach is a converged network core offering common applications via all types of access technologies. This session will outline how operators can deliver rich-media content and applications in an IMS-enabled all IP mobile network. The role of application servers, media storage servers and media delivery servers will be described that are collectively used to deliver such services.

Wireless Optical Mesh scales up WiFi Telephony in Business Areas
(WM-03)
Thursday - 01/25/07, 1:30-2:15pm
The promise to be able to utilize the ubiquitous WiFi service presence as a next generation mobile voice infrastructure is huge, but many impediments have lowered the once rampant expectations for public WiFi telephony. Newly emerging WiFi products, based on the evolving 802.11 standards suite, will support CoS and transport prioritization and can support VoIP calls with good quality across a small WiFi mesh.
However, service interference will always be an impediment, limiting the scalability of WiFi telephony across larger mesh deployments. A new wireless technology, the wireless optical mesh, can enhance the WiFi telephony experience. Utilizing interference free spectrum, wireless optical mesh technology has no delay or jitter and delivers toll-grade voice quality on a large scale. Come to this session to learn all about this emerging technology.

Validating Mobile and VoIP Numbers With a Modern Line Information Database
(WM-04)
Thursday - 01/25/07, 2:30-3:15pm
With more and more people using only their mobile and VoIP phones, landline users with caller ID are getting an increasing number of “unknown name” or “out of area” calls — at least some of which are from those wireless callers. In order to address the situation, carriers need to begin storing caller name information (CNAM) associated with mobile and VoIP phones in line information databases (LIDBs). And not just for caller ID purposes either. Businesses also use CNAM for added levels of security and verification of identity. If people are using wireless phones as their sole means of communication, it is more important than ever to be able to validate mobile and VoIP numbers. The speaker will discuss real world deployment experiences.

Delivering TRUE Broadband Wireless Today: VoIP over WiMAX
(WM-05)
Thursday - 01/25/07, 3:30-4:15pm
Today, 2G/2.5G wireless networks are reaching maturity in services and subscriber growth, and the harsh reality is that 3G technology offers only incremental improvements with high network upgrade costs. Furthermore, these networks are optimized for circuit-switched voice and not for IP services, thereby limiting the breadth of services that can be offered. In these networks, the migration to an all-IP network will be slow and painful. Also, we run the risk of the 4G architectures currently under study for the future being “too little, too late.”
However, as the only true broadband wireless solution that is available now, WiMAX has the potential to actually deliver VoIP as well as data, and IP Video because it is already optimized for All-IP service delivery. This presentation will discuss how operators can take advantage of broadband wireless technology today to move into new markets worldwide to set themselves apart and win favor with end-users. It will also discuss how an all IP IMS infrastructure will play a key role in enabling new service innovation with WiMAX.
