电信企业爱立信近日提出一项协调多种第三代移动通信标准的方案。爱立信的这一方案是以降低宽带码分多址(WCDMA)切片率为基础,把切片率由现时的4.096Mcps 减至3.84Mcps。它将有效地协调 WCDMA 和 CDMA2000两种网络系统,从而使生产低成本的双模式移动电话及终端产品成为可能,让用户在两种第三代网络系统标准之间自由切换。因而,这一方案将是与全球通(GSM)、北美蜂窝系统(TDMA IS-136)、窄
Ericsson, a telecommunications company, recently proposed a plan to harmonize multiple third-generation mobile communications standards. Ericsson’s proposal is to reduce the slicing rate from the current 4.096Mcps to 3.84Mcps based on reducing the WCDMA slicing rate. It will effectively coordinate both WCDMA and CDMA2000 network systems, making it possible to produce low-cost dual-mode mobile phones and end products that allow users to switch freely between two third-generation network system standards. Thus, this solution will be in line with GSM (GSM), North American Cellular System (TDMA IS-136), Narrow
