private mobile radio system

用法例句

This paper proposed an efficient handoff algorithm for heterogeneous networks,which are constructed by wireless local area network(WLAN) and universal mobile telecommunications system(UMTS).

针对移动台在异构网络之间切换性能不理想的问题,提出基于通用移动通信系统(UMTS)和无线局域网(WLAN)构建的具有接入控制单元(ACU)的异构网络模型。

As a family member of EVIT-2000, UMTS adopts WCDMA as its radio transmission technology, thus UMTS is well-known as WCDMA communication system.

作为3G候选方案之一，通用移动通信系统(Universal Mobile Telecommunication System,UMTS)采用宽带码分多址(Wide-band Code Division Multiple Access,WCDMA)作为其无线传输技术，因此也把UMTS系统称为WCDMA通信系统。
