摘要
有线电视同轴电缆能够低损耗传输2.4GHz Wi Fi信号,加之有线电视无源接入网与Wi Fi室内分布系统传输网络结构相似、功能相近,在对有线电视无源接入网进行简单改造后即可实现2.4GHz Wi Fi信号的稳定传输与覆盖。作者实测结果表明,该模式下Wi Fi信号覆盖均匀、接入稳定,实测数据也验证了理论计算结果。对比广电网络传统技术模式,利用无源接入网直接传输Wi Fi并实现覆盖,可实现20Mbps以上的宽带接入,同时连接稳定,成本低廉,管理手段完善,能够作为未来广电网络实施"无线家庭"战略的重要技术手段。
2.4G WiFi signals can be transported with low signal loss by cable. In view of the fact that cable passive access network and indoor WiFi distribution system have similar structures and functions, therefore cable passive access network can be used to transport and cover 2.4G WiFi signals after being simply remade. The measurement results indicate that WiFi signals are well-distributed with steady.The signal power conforms to theoretical calculation. In contrast to traditional cable network transport mode, passive access network can be used to transport WiFi signals directly, implements signal coverage and provides bandwidths of 20Mbps or above. With stable network connection , low cost and rich management tools, it can become the important methods for broadcast network to implement ＇Wireless Home＇ strategy in the future.
