基于有线电视同轴电缆传输WiFi信号的设计与仿真

摘要

In order to effectively solve the instable problem of wireless signal transmission in modern architecture,this paper proposed the scheme of using coaxial cable to transmit 2.4 GHz wireless signal.The better transmission performance of WiFi signal in coaxial cable is verified by testing the attenuation performance of 2.4 GHz signal spreading in coaxial cable.In the end,the hybrid and distribution circuit of CATV signal and WiFi signal is designed and simulated.Through actual measurement,the applicability and reliability in transmission of the circuit under the traditional home wiring is verified.%为了有效解决家庭WiFi信号传输不稳定的问题,提出了基于有线电视同轴电缆传输WiFi信号的方案.通过测试无线信号在同轴电缆中的衰减性能,验证了WiFi信号基于同轴电缆传输比在自由空间传播有更好的传输性能.最后设计和仿真了有线电视信号和WiFi信号的混合分配电路,经过实际测试,验证了其在一般家庭布线下传输的适用性和可靠性.
