Next evolution of CDMA 1x EV-DO one step nearer

Business IT - Technology

CDMA developer, Qualcomm, has hailed a recent successful test call as a major milestone in the development of the next stage of CDMA 1x EV-DO technology, Rev. A.

Qualcomm says that successful Rev. A test calls were made using prototype equipment based on Qualcomm's Cell Site Modem chipset for base stations and the Mobile Station Modem chipset for mobile handsets.

EV-DO Rev. A supports peak data speeds of 3.1Mbps on the forward link and 1.8 Mbps on the reverse link and, according to Qualcomm, "the higher system capacity required for compelling next-generation wireless services."

Barry West, CTO of US carrier, Sprint Nextel, said that besides increasing data speeds, Rev. A would "facilitate real time applications that ride on top of the all IP wireless converged network. Applications such as voice over IP, high-performance push-to-talk, and higher-speed data access are just some of the examples of new services our customers will enjoy with the advent of EV-DO Rev. A."

EV-DO Rev. A also provides lower latency with QoS to enhance the user experience for delay-sensitive applications such as VoIP and video telephony. According to Qualcomm, "'Gold' and 'Platinum' multicast services that are supported by EV-DO enable the delivery of high-quality multimedia content to a large number of users simultaneously. Industry-wide efforts are underway for further developments of CDMA technology that will enable even faster data rates and new mobile capabilities."
