In (partial) praise of IPaq 6315

Okay I got to use the iPaq 6315 for about a week and have some impressions. I think if you are a PC user, and have a user-friendly tech-support department, then this is a good device for you to carry on day trips. I got to configure and use it with my T-Mobile service within minutes, since most of the settings come preloaded into the device. The software collection that is bundled with this device will meet most of your needs. The new device is a quad-band global communicator, and can roam seamlessly from one corner of the world to the other. It is also quite easy to connect with the T-Mobile hotspots. I tried to connect with a bluetooth headset from Plantronics, with success in less than ten minutes. The thumb board provided with the device is good enough for answering emails and sending quick SMS messages. I installed the XTen softphone on the device, and boom I was making VoIP calls using my Vonage account.



Feature-Rich VOIP in the Works

With voice-over-IP services popping up like summer weeds, providers are predicting that rich feature sets will ultimately win new customers.

To that end, WorldWide Telco Inc. plans to unveil a series of features over the next two months. The New York-based vendor has developed its own telecommunications software platform and customer premises equipment to provide a service it calls wIPphone.



Qualcomm Conducts VoAirplane Test

Taken from GekoNews

On July 15, Qualcomm conducted a wireless VoIP test on an American Airlines commercial airplane, enabling passengers with commercially available CDMA mobile phones to place and receive calls and text messages in-flight. The technology employed Qualcomm’s 3G picocell network and UTStarcom’s Moving Media 2000 softswitch to support a VoIP connection between an in-cabin CDMA cellular base station and an air-to -ground Globalstar satellite link.

Boeing conducted a similar VoAirplane test last month, supporting in-flight PC to phone connectivity on a Lufthansa aircraft using Xten’s softphone.
