Patent ID: 7366150

Claim:
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.
