摘要
GSM（全球通）是向公众开放的无线移动通信网,技术成熟、覆盖地域广阔。基于电路交换模式的GSM数据通信可用于远程无线数据传输。试用表明,该方法具有实时性好,数据传输稳定,使用的设备小巧,成本低,无需架设高架天线等优点,尤其适合组建远程无线数传网。
GSM is the public wireless mobile communication network,which has mature technology and covers the broad geographic area.GSM data communication based on circuit-switched can be used for remote wireless data transmission.Trials show that the method is real-time and data transmission is stable.The equipment is small and low-cost,without antenna.This model is particularly suitable for the formation of a long-range wireless data transmission network.
