QUALCOMM began sampling first chipset for CDMA2000 1xEV-DO Revision A. In addition to support Rev A’s higher data rates and QoS enhancements, the new Mobile Station Modem MSM6800 chipset also provides increased processing capacity and optimized audio, video, camera and graphics capabilities.
CDMA2000 1xEV-DO Rev. A supports faster data rates and higher system capacity to enable operators to offer in-demand, next-generation wireless multimedia. Capabilities include:
- Optimized for packet data service. Supports peak data rates of up to 3.1 Mbps on the forward link and up to 1.8 Mbps on the reverse link.
- Supports QoS for delay-sensitive applications, including a variety of IP-based services such as VoIP and real-time conversational services such as push to talk, video telephony, low-delay gaming and “instant multimedia” (an extension of push to talk that combines immediate voice with simultaneous delivery of video and pictures).
- Supports 1xEV-DO Gold Multicast, which enables the delivery of high-quality video and audio to a large number of users simultaneously. If standards progress permits, Qualcomm’s MSM6800 chipset will also support 1xEV-DO Platinum Multicast.
QUALCOMM said its new MSM6800 chipset would enable mobile next-generation wireless multimedia device incorporating features such as 4.0 megapixel cameras, video camcorders at 30 fps, graphics at 100k triangles/second. , 7M pixels/second graphics for console-quality gaming, 3D sound and MP3/AAC/aacPlus audio support, GPS location awareness, Mobile Digital Display Interface (MDDI) connectivity, and integrated Bluetooth 1.2.
QUALCOMM’s 1xEV-DO Rev. A solutions also include the Cell Site Modem CSM6800 device, which sampled in December 2004. The CSM6800 device has been chosen by several leading vendors for infrastructure and test equipment.
