Wireless network system using power line communication

Abstract

A wireless network transmission system using a power line communication (PLC), which can connect at least one ultra-wideband (UWB) network by using a UWB relay and support communication between different UWB networks. The wireless network transmission system using a PLC includes: a first pico-net including at least one device generating a UWB data signal; a UWB relay unit transforming the UWB data signal into a PLC data signal; and a power line unit mechanically connecting the first pico-net and a second pico-net, and transmitting the transformed PLC data signal to the second pico-net.
