First Claim
1. An indoor local area network (LAN) system comprising:
- at least a first remote terminal comprising;
(i) an ultra wide-band (UWB) conversion module for converting input digital data into analog data in an ultra wide-bandwidth far transmission from said at least first remote terminal and converting a received analog signal into a digital signal; and
(ii) an antenna connected with said UWB module for wirelessly;
transmitting the converted analog signal from the UWB module in the ultra wide-bandwidth, and receiving an analog signal in an ultra wide-bandwidth;
at least a first access point for performing UWB-based wireless communication with said first remote terminal in a corresponding area, said access point receiving said analog signal of the ultra wide-bandwidth transmitted from said first remote terminal and converting the received analog signal into an optical signal wherein said access point does not include a UWB module; and
a central unit in communication with said first access point via an optical cable, said central unit comprising;
a central unit optical transmitter/receiver module for receiving said optical signal from said first access point optical transmitter and converting the received optical signal into an electrical signal, comprising;
a UWB module for receiving said electrical signal converted by said optical transmitter/receiver module and converting the received electrical signal into a digital signal; and
a routing module for determining a destination of said digital signal converted by said UWB module from said digital signal, getting up a transfer path of said digital signal based on the determined result and sending said-digital signal to said UWB module with information regarding said transfer path contained therein.

Abstract
An indoor local area network (LAN) system using an ultra wide-band (UWB) communication system is provided. The indoor LAN system includes at least one remote terminal including a UWB module for converting input digital data to be transmitted into an analog signal of an ultra wide-bandwidth and wirelessly transmitting the converted analog signal via an antenna of the remote terminal. The UWB module receives an analog signal of the ultra wide-bandwidth via the antenna and converts the received analog signal into a digital signal. The indoor LAN system further includes at least one access point for performing USB-based wireless communication with the remote terminal in a corresponding area. The access point is adapted to receive the analog signal of the ultra wide-bandwidth transmitted from the remote terminal and convert the received analog signal into an optical signal.
