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.

Claims

1. A wireless network transmission system comprising:

a first pico-net including at least one device generating an ultra-wideband (UWB) data signal;

a UWB relay unit transforming the UWB data signal into a power line communication (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.

2. The system of claim 1, wherein the UWB data signal generated from the at least one device includes a pico-net identifier and a destination address.

3. The system of claim 1, the UWB relay unit comprising:

an antenna unit transmitting/receiving the UWB data signal from the at least one device included in the first pico-net;

a signal transformation unit transforming the UWB data signal into the PLC data signal;

a UWB module unit identifying a pico-net identifier of the UWB data signal, and routing the UWB data signal according to the pico-net identifier; and

a high speed PLC modem unit multiplexing the transformed PLC data signal to transmit to the power line unit.

4. A UWB relay of a wireless network transmission system, the relay comprising:

an antenna unit transmitting/receiving a UWB data signal transmitted from at least one device included in a first pico-net;

a signal transformation unit transforming the UWB data signal into a PLC data signal;

a UWB module unit identifying a pico-net identifier of the UWB data signal, and routing the UWB data signal according to the pico-net identifier; and

a high speed PLC modem unit multiplexing the transformed PLC data signal to transmit to a power line unit.
