BT Trials Voice-over-Wi-Fi
By: MarkJ - 16 March, 2005 (9:40 AM)

BT is preparing to trial technology capable of routing mobile phone (GSM) calls over wireless local area networks (WLANs):

The trial of the voice-over-WLAN (VoWLAN) technology is due to begin in April this year at BT's Adastral Park research and development labs in Martlesham Heath, UK.

Participants in the trial will use a HP iPAQ 6340 PDA which is able to connect to WLAN and GSM networks. Mobile services company Tatara Systems is providing the SIM authentication technology for the project.

The trial will be initially limited to the Adastral facility, but BT's eventual aim is to develop a device that will allow consumers and business users to make mobile calls over WLAN networks in the home, office or via public hot spots, as well as over GSM networks.

It's a good idea, yet could call into question the future of 3G mobile phone broadband technology. More @ ZDNet.
