基于INT6400的电力线宽带调制解调器性能测试

摘要

Modem of broadband power line communication (BPL) is a new device for broadband access using low-voltage power line as transmission medium. It provides a new solution for the "last mile" with low cost and wide coverage. In order to verify the performance of BPL modem, this paper gives out a test of BPL modem based on INT6400 in terms of response time, data rate, loss rate and interference of other devices. Then it takes a comparison between BPL and Ethernet broadband access, and analyzes the major influencing factors of BPL modem. Finally an application foreground of BPL modem has been predicted.%电力线宽带(BPL)调制解调器是一种新的宽带接入设备,它使用低压电力线作为传输介质,具有成本低、覆盖广等优点,为解决“最后一公里”问题提供了一种新的解决方案.为了验证电力线宽带调制解调器的实际性能,本文以基于INT6400芯片的电力线宽带调制解调器为例,从响应时间、数据传输速率、数据包丢包率以及其他电器设备的干扰几个方面对其做了测试,并与一般的以太网宽带接入进行横向对比,分析了影响电力线调制解调器性能的主要因素,最后对电力线调制解调器的应用前景做出了展望.
