Description
本发明涉及通信技术领域,尤其涉及一种数据传输方法及装置、数据接收方法及装置。
无线网络(Wi-Fi)常见的是使用无线路由器,在无线路由器的电波覆盖的有效范围都可以采用无线保真连接方式进行联网,如果无线路由器连接了一条ADSL线路或者别的上网线路,则又被称为热点。由于“热点”所发射出的电波可以达到距接入点半径数十米至100米的地方,用户只要将支持无线保真的笔记本电脑或PDA或手机或psp或ipodtouch等放到所述区域内,即可高速接入因特网。
但是,无线保真信号也是由有线网提供的,比如家里的ADSL、小区宽带(统称为公网)等,只要接一个无线路由器,就可以把有线信号转换成无线保真信号。但是,在某些场景中,公网连接会变得不稳定。比如,由移动路由建立的WiFi热点通常使用3G/4G来上网,而3G/4G上网受环境影响很大,容易变得不稳定,尤其是在荒郊野外的时候,公网稳定性非常差,使得通过热点产生的无线网络也无法通信,对于外出旅游的用户来说,非常不便。
