华为卫星通信布局5G智能手机卫星通话VG7050EAN爱普生晶振X1G004541100900
如果某一台智能手机的用户在纽约市中心拨打电话,而此时5G信号很好的话,那么智能手机将自动使用5G模式来进行通话.但是如果这个用户前往郊区旅游,而当地已经超出了5G通话的服务区的话,那么这台智能手机将会切换到窄带卫星通信系统并使用对应区域内的轨道卫星.窄带卫星通信
一般来讲窄带卫星通信会使用一个或多个轨道卫星来实现用户之间的联络.因此与使用蜂窝基站来帮助用户完成无线通信的传统不同,这种全新的通信方式将会为用户提供一个额外的选项,即利用窄带卫星来完成通信.这种智能设备可以根据某一时间点的数据连接质量来在5G连接模式以及窄带卫星连接模式之间进行迅速切换.
