Indoor local area network system using ultra wide-band communication system

A method for providing an indoor local area network (LAN) system comprising the steps of:

• (a) providing at least a first remote terminal comprising:
• (i) an ultra wide-band (UWB) conversion module for convening input digital data into analog data in an ultra wide-bandwidth for 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 of the remote terminal in the ultra wide-bandwidth and
• receiving an analog signal in an ultra wide-bandwidth via the antenna
• (b) performing UWB-based wireless communication with said first remote terminal in a corresponding area by at least a first access point, said access point receiving said analog signal of the ultra wide-bandwidth transmitted from said first remote terminal and convening the received analog signal into an optical signal wherein said at least first access point does not include a UWB module;
• and
• (c) providing a central unit, including a central unit UWB module and the central unit in communication with said first access point via an optical cable, said central unit;
• receiving said optical signal from said first access point optical transmitter and converting the received optical signal into an electrical signal by a central unit optical transmitter/receiver module:
• receiving said electrical signal converted by said optical transmitter/receiver module and convening the received electrical signal into a digital signal by the central unit UWB module;
• and
• determining a destination of said digital signal converted by said UWB module from said digital signal, setting 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 by a routing module:
• wherein
• said central unit UWB module is adapted to convert said digital signal containing said information regarding said transfer path set un by said routing module into an analog electrical signal of the ultra wide-bandwidth and send the converted analog electrical signal to said central unit optical transmitter/receiver module;
• and
• said central unit optical transmitter/receiver module is adapted to convert said analog electrical signal converted by said UWB module into an optical signal and transmit the converted optical signal to said first access point for management of a network to which a destination remote terminal corresponding to said transfer path information belongs.

An indoor LAN system comprising:

• a first area, a second area, and a third area of sub-networks each having respect nodes therein;
• a first access point, a second access point, and a third access point, each of the first, second and third access points being associated with a respective area;
• a central unit in communication with each of the first, second and third areas and with an external network, comprising:
• a central unit optical transmitter/receiver module for receiving said optical signed 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, setting 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;
• wherein each of the access points and nodes within a corresponding area communicate via Ultra Wide Band (UWB) communication;
• and
• wherein each of the access points and the central unit communicate via optical fiber and the central unit includes a UWB module;
• and
• wherein each of the access points includes a optical transmitter/receiver module for converting optical communication from a corresponding area central unit and converting said communication into an analog UWB signal to communicate with at least one of the respective nodes wherein said access points do not include a UWB module.
