868MHz频段微功率设备研究

Study on 868MHz Short Range Devices

随着无线通信技术的演进,微功率短距离无线电发射设备作为物联网不可或缺的终端设备倍受关注。本文首先介绍868MHz频段在国际上的规划情况,同时讨论了该频段微功率设备的主要技术体制,最后研究了868MHz频段微功率设备的型号核准情况和主要应用场景。

With the development of wireless communication techniques, as important terminal component, short range devices (SRD) attracts more and more attention. This paper introduces international spectrum management on 868MHz. Then three technique alliances are given. The 868MHz SRD type approval data and application ifeld are studied afterwards.
