More than one-third of the employees regularly use

their mobile phone around the office

Over two-thirds of laptop users have WiFi, though

over one-third 'rarely ' or 'never' use it

Mobile VoIP and Dual-Mode Phones

Consistent growing expectations from market analysts

"FMC will drive the adoption of next-generation handsets, primarily dual-mode Wi-Fi/cellular handsets, which will enable users to

seamlessly handover from a cellular mobile network to a WiFi one and vice versa, so as to provide optimum quality of service“

Source: Frost & Sullivan - November 2006

“The fastest growing segment in the market by far is the dual-mode WiFi/cellular VoIP phone, with worldwide units shipping at a

phenomenal rate: the 5-year forecasts is for a compound annual growth rate of 198% between 2006 and 2010.”

Source: Infonetics Research - January 2007

“Worldwide VoIP over Wi-Fi equipment revenues are expected to reach over $82bn by 2012. North America will lead the market at $35bn in revenues, along with EMEA (Europe, Middle East Africa) with $23bn and Asia Pacific with $21bn. Dual Mode Mobile Handsets (Cellular/VoIP over WiFi) will dominate this market generating almost $68bn in revenues by 2012”

In a Nutshell…

The full vision of FMC is for people to use

FMC leverages dual-mode devices to take

advantage of less expensive, high-speed

connectivity within the office, the home or a public

hotspot location, while enjoying wide-ranging

IMS – IP Multimedia Subsystem

IMS seems today to be the most promising approach to fully

accomplish the FMC vision to deliver compelling next

generation communication services to people:

¾

It is based on IP and

compatible with SIP (the

winning VoIP signaling

standard), ….

¾

thus it will also be capable

of smoothly integrating the

current IP-Centrex VoIP

platforms.

However, some more time

is needed to see IMS

IMS – Timing

What About UMA/GAN?

¾ It extends mobile voice and data GSM/GPRS services over unlicensed spectrum

technologies (including both WiFi and Bluetooth)

¾ Whilst of some interest for Consumers, it is not a viable solution for Businesses (as it does not provide a true

integration between the

enterprise telephony systems and mobile voice networks) ¾ It also does not integrate well

Conclusions

‰ Fixed-Mobile Convergence is multifaceted, as it is not all about network technologies.

‰ The spreading of wireless LANs and the growing availability of reliable and reasonably priced dual-mode phones is accelerating the adoption of Mobile VoIP.

‰ Looking at solutions, IMS, and not UMA/GAN, seems today to be the most promising approach to fully accomplish the FMC vision and deliver compelling next generation services in the mid-long term. ‰ In the meantime, there is already the possibility to concretely take

advantage of the first significant benefits of FMC.

‰ In particular, mobile VoIP solutions based on dual-mode phones

connected over WiFi to IP-Centrex platforms, like Elitel Futura TWIN, can provide Business customers with seamless access to the
