Analysis of the Coexistence of Indoor Broadband Communication Network for Smart House
家庭智能宽带局域网络共存性研究

The indoor broadband LAN (Local Area Network) is the extension of the Internet and is also the technique basement of the smart house in the future. This paper introduces one novel method to make up the indoor broadband network firstly with the BPL (Broadband Power Line) communication and the UWB (Ultra Wide Band) communication techniques, which make kinds of indoor equipments connected into the LAN. Then on the base of the transmission and radiation characters of the BPL, the coexistence of the BPL and the UWB is analyzed on two sides: the electromagnetic radiation and the signal analysis. After simulating the BPL signals and testing the radiation, the calculation model for BPL system is proposed to analyze the performance of the UWB BER (Bit Error Ratio) in the BPL radiation field. The result shows that two broadband communication techniques are suitable for coexistence, which supports a relevant technique basement of the normative indoor broadband LAN for the smart house.
