双频技术是指GAM900兆移动通讯网络技术与GSM1800兆技术的相结合,在现实中,各大城市的GSM900兆网日趋饱和状态,网络繁忙,抢不上线,断话等现象时有发生,而GSM1800兆移动通信网为解决眼前繁忙的GSM900网络的拥堵现象提供了最佳方案。 双频技术的最大优点在于它提供了额外的容量,在人口稠密地段,如果安装了GSM1800基站,问题即会迎刀而解。首先双频网络会自动识别用户使用的手机,同时双频手机可以在GSM900/1800两者之间自由切换.自动选择最佳信道进行通话,即使在通
Dual-band technology refers to the combination of GAM900 trillion mobile communication network technology and GSM1800 trillion technology. In reality, the GSM900 trillion network in major cities is increasingly saturated, the network is busy, the network can not be grabbed, the call-breaking phenomenon occurs from time to time, GSM1800 trillion mobile communication network to solve the busy GSM900 network congestion phenomenon provides the best solution. The biggest advantage of dual-band technology is that it provides additional capacity, in densely populated areas, if the GSM1800 base station is installed, the problem will be solved. First, dual-band network will automatically identify the user’s mobile phone, while dual-band handsets can switch freely between GSM900 / 1800. Automatic selection of the best channel to talk, even in the pass
