摘要:

The standard ECMA-392 specifies a physical layer and a medium access sub-layer for wireless devices to operate in the TV frequency bands,wireless network working in TV white space(TVWS) has enhanced coverage range and robustness,and less power consumption.Based on the hardware of network devices using ECMA-392 technology including transceiver,digital signal process,and high level process module,control reference model based on MAC superframe structure is provided.A clock synchronization block is needed to make device synchronize in superframe period. An ECMA-392 network application established by TV broadcast operator is analyzed as an example.

Abstract:

分析了ECMA-392标准的物理层特性，该技术可以提高无线网络的信号的覆盖范围和可靠性，并降低功耗。基于ECMA-392标准的网络设备硬件(包括收发信机、数字信号处理、上层处理等几部分),给出了以超帧结构为基础的设备控制参考模型，包含时钟同步模块以保证超帧周期内设备之间的同步。对电视运营商采用ECMA-392技术建立无线网络应用方案进行了分析。
