CCI's new 3G PDA/videophone will be based on an Intel PXA270 XScale processor, according to Radvision. The company says it developed the CCI videophone application using its 3G-324M Toolkit, in collaboration with both Microsoft and Intel. The toolkit includes APIs for 3G-based multimedia communication devices.
About 3G-324MAccording to the
3G-324M Forum, 3G-324M is derived from the H.324M specification, which was defined by the International Telecommunications Union (ITU) in order to standardize multimedia communication over mobile networks. The 3G-324M modifications to H.324M address issues surrounding delay-sensitive real-time multimedia communications such as video conferencing.
Although the theoretical bandwidth of a full IP 3G network, 2 to 10 Mbps, should be sufficient to satisfy the needs of delay-sensitive communication, in practice bandwidth decreases as the number of users per cell and the distance from the cell increase, the Forum notes. 3G-324M solves these problems by using a dedicated circuit-switched channel of 64 Kbps, along with using the existing technologies of the circuit-switched network for functions such as addressing, billing, and management. This allows immediate deployment of video conferencing applications over 2.5G, 2.75G, and 3G networks, according to the Forum.
3G-324M is an "umbrella specification," comprised of the following sub-protocols, according to Radvision:
- H.245 for call control
- H.223 for bit streams to data packets multiplexer/demultiplexer
- H.223 Annex A and B for error handling of low and medium BER detection, correction, and concealment
- H.324 with Annex A and C for operating in wireless environment
AvailabilityCCI is described as "one of the largest ODMs [original design manufacturers] in the world," having supplied wireless handsets to Motorola, Panasonic, and Alcatel, among others. The company is headquartered in Taiwan and has manufacturing facilities in Nan Jing, China.
A release date for CCI's new 3G videophone/PDA device was not stated.
