各国的手机频率

各国的手机频率 各国的手机频率是多少, 世界各国GSM频率覆盖 表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf : 相信大家见过手机有两(双)频，三频，四频之分，那你知道到底是什么意思吗,做手机外贸的，这些更要清楚了: 手机分为双频GSM/GPRS (900/1800) 三频GSM/GPRS (900/1800/1900) 四频GSM/GPRS (850/900/1800/1900) CDMA的网络制式(800/1900) 800Hz在中国现在使用 ，1900Hz现在美国使用的～～～ 900MHZ是移动G网频段，1800MHz是D网频段。 所以3频手机会在900和1800频段来回切换。 具体选择哪个频段，要看当时网络参数。 英国现在使用的频段是WCDMA和GSM，中国的GSM就是从欧洲引进的。手机频率有双频，三频，四频，双频也不是只能在国内使用，在英国的话,如果你是GSM双频手机也能行 三频全球大多的地方都可以用，英国也可以,而四频在3频基础上是又加入了850这个频率，信号在有些国家会更好。 目前GSM制式的手机网络有四种制式普遍使用的是900M和1800M频段，国内的各各省份也不同有的地方只有900M如河北移动，有的地方只有1800M如安徽，有的地方900M和1800M都有如广东，不过国内的GSM手机都是双频自动切换的无需烦心。 1900M的频段只在美洲如美国(美国是900M/1800M/1900并存)、新西兰900M/1900M、还有巴拉圭都有1900M的网络频段，所以我们如果出国去这些国家一定要带一部三频手机，如NOKIA7610、6600、MOTO768、768i、松下GD88等。 目前厄瓜多尔的conecel公司使用的是850M的频段需要使用四频的手机才能使用，如v3i. 我国GSM手机占用频段是EGSM900Mhz和GSM1800Mhz，国内的800Mhz频development in order to protect a host of attractions and historical sites, as well as to maintain the economic vitality of the downtown area.

GSM-850 GSM-850 and GSM-1900 are used in the United States, Canada, and many other countries in the Americas. GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800MHz Band" when it was first allocated for AMPS usage in the United States in 1983. GSM-1900 GSM-850 and GSM-1900 are used in the United States, Canada, and many other countries in the Americas. GSM-450 Another less common GSM version is GSM-450[1]. It uses the same frequency as and can co-exist with old analog NMT systems. NMT is a first generation (1G) mobile phone system which was primarily used in Nordic countries, Eastern Europe and Russia prior to the introduction of GSM. development in order to protect a host of attractions and historical sites, as well as to maintain the economic vitality of the downtown area.
