This talk is being given by Peter Brockmann , SVP of Business Development with Firsthand Technologies. And he keeps a blog online at http://voip.brockmann.com.

Mobility is a huge issue and the advances ahead with fixed mobile convergence makes this a hot interest for many people.

The environment is ripe for Mobile VoIP. The delivery of enterprise applications, niformation and services to a mobile worker is vital today.

Some factors that have made Mobile VoIP viable today are standarizaation on SIP, Moore's law as it applies to mobile devices, and the vast improvements in mobile data networks.

Email on mobile phones was a 50% usage rate among people in the room. We are becoming mobile data users more and more. Enterprise users are a huge piece of the mobile services market and have been since 1973.

Control of radio specturm is a concern. Spectrum is a "public good." 3G and WiMax are licensed spectrum as opposed to WiFi, which has been set aside for fair use.

Contention for service is a real issue. All users are equal in most implementations, although 802.11e does provide for some real-timie prioritization.

Security aspects run from WPA to WPA2 to AES to 802.11i. User interactions and experiences are distracting and degrade the user experience.

Radio characterics present another factor.Current WiFi is very chatty in standby mode, draining mobile device batteries and shortening usable lifetime Dual mode devices experience greatly shortened battery life. There's industry work needed to make the WiFi device more effective as a phone.

Devices are widely available from an array of manufacturers. Issues include the procesor, screensm supported applications, battery life, and user expectations. Smart phones? Dual mode devices? Whatever we call them, they're a rapidly growing space. There are millions of mobile phones shipping.

They did a survey of 187 mobile professionals with some interesting results, Most are customer facing people or management. Most have their cell phone bill reimbursed by the company. Over 75% were happy with coverage. About half felt that dual mode could improve coverage for better service. Churn in the mobile industry is driven by coverage issues more than any other factor. Most mobile carriers are now down to about a two percent churn rate.

Business today is very mobile. 70 million Americans use their cell phones for work. 70% of all cell calls start in WiFi enalbed areas (home, office, hotel, etc.) By 2009 expect 25% of new mobiles will be smartphones.

Here's a good one 67% of mobile professionals receive or make more than 25% of their business calls on mobile phones. Mobiles are very important devices to business,

Those numbers came from a variety of surveys by FirstHand, Nortel, RHK and Gartner.

Interesting thoughts on presenting a company call to a mobile device with call handling options. This laps into some of te presence and availability discussions. Lots of people want it.

I'M from mobile phones is becoming more popular. Click to call vs. Click to I'M. Users says I'M is useful or very useful to 75% of survey resiondents.

Directory search window that provides presence status for enterprise use was listed as a very desirable feature.

Group call or conference calling is another aspect that has a lot of interest. Not just conference calls, but the ad hoc business "manager's call" on demand or regularly scheduled.

Mobile VoIP is much more than just terminating a SIP session on a small handheld device. There's a lot more to it. It's about enablibg a productive personal experience.

Peter did a great job on a brief presentation. Very nicely done.
