当个人通信业务(PCS)用户漫游出其网络覆盖范围进入IS-41蜂窝网的领地时,无线通信的奢华就突然结束了,手机不再工作了.在美国,有100多万个人通信业务用户,其运营者采用1.9GHz的GSM标准.这些用户和运营者很快就会在GSM和IS-41蜂窝网的漫游得到答案,其解决方法包括AMPS码分多址(CDMA)和时分多址(TD- MA).美国加州Synacom技术公司的RoamFree互通网关可将基于不同无线技术的网络连接起来,并增强了这些网络的功能.
When PCS users roam beyond the reach of their network into the territory of the IS-41 cellular network, the luxury of wireless communications suddenly ends and the phones no longer work. In the United States, more than 1 million personal communications business users , Whose operators are using the 1.9 GHz GSM standard and will soon be able to roam over GSM and IS-41 cellular networks with solutions that include AMPS code division multiple access (CDMA) and time division multiple access TD-MA). The RoamFree Interworking Gateway from Synacom Technologies, California, USA, connects networks based on different wireless technologies and enhances the capabilities of these networks.
