Music: tool - schism
gizmodo seems to have giant wood over this new verizon phone (warning: more LotR references than you can shake a stick at).

while it is cool, the omission of VoIP almost pains me. why would you put a broadband modem & router into a phone and then not add that functionality? would have taken it from "nifty" to "killer app", IMO. if everyone i know hadn't already abandoned telco service in favor of cell phones, i'd be wondering if they took a bribe to leave that out...

VOIP requires sub 50ms roaming times. This is very possible for unsecured connections with most modern PHY chips. However, for secured connections this requires that the infrastructure (and phone) supports the IEEE 802.11i specification. There aren't many corporations that have deployed the upgraded hardware necessary to support the needed infrastructure. Additionally, the client software on the phone would have to support some EAP method (like EAP-TLS, LEAP, or PEAP). This creates a barrier to entry as this would be a programming headache for most phone companies.

hmm. but if the broadband modem is integrated into the phone, you could at least do VOIP with the phone itself (not necessarily with any wireless clients connected to it), couldn't you?

good to see you around again, update or something :P

If a TCP/IP stack has been implemented on the phone, then it wouldn't be that much more effort to add a VOIP application that runs on top of the transport layer. Wired communications is typically faster and certainly more reliable than wireless though. The wired connection is constantly on, while with wireless communication, the application is competing for bandwidth. A wireless compatible VOIP application is therefore more difficult to implement. Again, the complexity of the application and relatively modest market demand are the *likely* reasons 'they' chose not to include a VOIP application on your phone.

Windows-based cell phones are going to be really hot this Christmas. Check out the features on some of the new models. ;)
