The joke about CDMA that the UWCC guys remind me of, is that there is no IMT-2000 published standard for CDMA, that extends data rates above 144 kbps, and when there is that the 1xMC standard will be for 307 kbps as opposed to the 384 kbps requirement of IMT-2000, that the EDGE standard satisfies. ---------- 1x EV-DV specifications in progress will support both RF channel bandwidth(s) 1.25 MHz (1xMC) and 5 MHz (3xMC), will be IMT-2000 compliant, will be both ANSI-41 and GSM Map compatible, and the following minimum performance requirements: "provide peak (i.e., maximum instantaneous) data rates when serving only packet data traffic for any user in an outdoor, high speed vehicular environment as follows: a) At least 2.4 Mbps on the forward bearer channel. b) At least 1.25 Mbps on the reverse bearer channel. "provide system-wide average data rates per 1.25 MHz radio channel when serving only packet data traffic in a fully loaded system in an outdoor, high speed vehicular environment as follows: a) At least 600 Kbps on the forward bearer channel b) At least 600 Kbps on the reverse bearer channel c) Both the forward and reverse channel requirements must be met simultaneously "provide peak (i.e., maximum instantaneous) data rates when serving only packet data traffic for any user in a pedestrian speed environment as follows: a) At least 2.4 Mbps on the forward bearer channel b) At least 2 Mbps on the reverse bearer channel c) Both the forward and reverse channel requirements must be met simultaneously "provide peak (i.e., maximum instantaneous) data rates when serving only packet data traffic for any user in a stationary indoor environment as follows? a) At least 2.4 Mbps on the forward bearer channel b) At least 2 Mbps on the reverse bearer channel c) Both the forward and reverse channel requirements must be met simultaneously When operating in a radio channel that is restricted to supporting only packet data services that are not QoS constrained, will a) Provide a peak (i.e., maximum instantaneous) data rate for any similarly located user that is greater than or equal to the peak data rate provided by any system which supports the 1xEV-DO specifications. b) Provide a system-wide average data rate per 1.25 MHz radio channel in a fully loaded system that is greater than or equal to the system wide average data rate per 1.25 MHz radio channel provided by any system that supports the 1xEV-DO specifications. 1xEV-DV specification will be capable of supporting both symmetric (for data rates up to the peak reverse bearer channel data rate) and asymmetric modes. 1xEV-DV specification will support all combinations of traffic types with varying QoS-constraints including voice, video, and data on a single radio channel. 1xEV-DV specification will support segregation of traffic types with varying QoS-constraints including voice, video, and data onto separate radio channels. 1xEV-DV specification will support multiple, concurrent packet data sessions per user. Approximate date for 1x EV-DV approval - June 2001. ben
