UG!!W-CDMA inability to syncronize voice and vidio discovered in HK W-CDMA trial. In Vidio Conferencing, consistantly lags data by as much as 1 to 2 seconds. JohnG telecomasia.net Voice will lag video on 3G, Hong Kong trial finds A W-CDMA trial in Hong Kong by competitive carrier, New T&T, concluded that voice will lag behind moving images during video-conferences over 3G systems by as much as 2 seconds. The trial successfully demonstrated circuit switched voice and packet oriented multi-media services running over the 3G air-interface. Samples of mobile radio interface signaling layer 3 messages and RF parameters were also measured for reference. The test, conducted in Hong Kong, tested 2-way video conferences with the network speed set at 384kbps, 128 kbps and 64kbps. The test used Meeting Point version 3.01 for the trial. New T&T said in a submission to the Hong Kong regulator, OFTA, that all applications ran smoothly on all three different network settings, but that "voice lags behind video by 1 to 2 seconds regardless of speed of transmission." The report also found that most applications, including video conferencing, video streaming, and Web browsing worked over the lowest speed setting of 64kbps although quality was compromised. Back
