Ericsson demos video calls on dual-mode handsets By Junko Yoshida EE Times, 11 February 2003 (8:43 p.m. GMT) eetuk.com PARIS — Ericsson Mobile Platforms, a licenser of open-standard 2.5G and 3G technology platforms for mobile handsets, said Tuesday (Feb. 11) that it could demonstrate video calls on an integrated, dual-mode W-CDMA and GSM/GPRS mobile platform. "We have fully integrated standard-based video telephony functionalities and complete protocol stacks into mobile handset chip sets based on our new dual-mode platform," said Tord Wingren, president of Ericsson Mobile Platforms, a subsidiary of mobile phone maker Ericsson. Using two pre-commercial mobile handsets based on Ericsson Mobile Platform's building blocks, mobile video telephony calls can now be made between a GSM/GPRS network and a W-CDMA network, Wingren said. Ericsson's demonstration shows standards-compliant video telephony operating between two test phones running on the 64-kbit/second circuit switch bearer to deliver 15 video frames per second. Further, it also shows video streaming on the 384-kbit/s packet data bearer. "We are using standard-compliant protocols and bearers. No special tricks are involved," Wingren said. There are "real challenges" to running video telephony in a mobile environment where "users are not standing still but moving about," Wingren said. Stable handshaking and handover of video calls and suitable error corrections are essential in "robust, high-quality" mobile video calls, he said. Using video-enabled dual-mode handsets, Ericsson will publicly demonstrate full video telephony next week at the 3GSM World Congress in Cannes, France. Wingren predicted that video telephony-enabled handsets will start to emerge in Europe "this summer," creating a high-volume market.
