摘　　要：在分析IEEE 802.11a和E1传输两种技术各自特点的基础上,介绍了基于802.11a的E1无线传输系统的系统构成,提出了该系统几种典型的应用模式,并与传统的E1微波传输系统做了比较。基于802.11a的E1无线传输系统具有频段无需申请、组网方式灵活多样、可同时传输E1数据和IP数据以及成本低廉等优势,可作为传统E1微波传输系统的替代和补充而广泛应用。The respective features of IEEE 802.11a and E1 transmission are introduced.The system structure is described.The typical application modes of the wireless transmission systems based on IEEE 802.11a are presented.Compard with the traditional E1 microwave transmission systems,the E1 wireless transmission system based on IEEE 802.11a can be easily constructed in many ways for much lower cost,and it can multiplex E1 data and IP data while using free frequency band. The system can be used as a substitute of or a supplement for the traditional E1 microwave transmission systems.
