基于FPGA的无线接入点硬件平台的设计与实现

Design and implementation of wireless access point hardware platform based on FPGA

基于认证、安全及QoS等方面的研究需要,提出了基于FPGA的HostAP设计方案,并搭建了无线接入点的硬件平台,在此平台上进行了硬件的裁减与集成;设计和实现了无线接入点的硬件电路,完成了无线接入点的高速PCB布局布线。在PCB布局布线的过程中,重点解决了高速印制电路板设计中的传输线效应问题,最后进行了实际的系统测试。

The design＇scheme of HostAP based on FPGA platform was presented for the demand of authentication, privacy and QoS. The scheme included both hardware and software parts. The former was based on the ML310 FPGA platform, and the latter was based on the HostAP. Furthermore, the creating and pruning methods of the wireless access point hardware platform were given. All of the circuits and the printed circuit board （PCB） were designed and implemented. During the process of the high speed PCB layout, the problems of transmission line effects were solved. To validate the design, test results are given.
