Embodiment Construction

[0020] now refer to figure 1 A wide area connection 101 may be connected to a wireless gateway or access point (AP) 100, eg, an Ethernet connection, a T1 line, a broadband wireless connection, or any other electrical connection providing a data communication path. The wireless gateway 100 sends RF signals such as IEEE 802.11 packets or signals based on Bluetooth, Hyperlan, or other wireless communication protocols to client units 104, 105, which may be personal computers, personal digital assistants, or Any other device capable of communicating with other devices via one of the above mentioned wireless protocols. Respective propagation or RF paths to each of the client units 104,105 are indicated as 102,103.

[0021] While the signal carried on RF path 102 has sufficient strength to maintain high-speed data packet communication between client unit 104 and wireless gateway 100, the signal carried on RF path 103 and intended for client unit 105 is will be attenuated when there...

Abstract

A frequency translating repeater ( 200 ) for use in a WLAN environment includes an in-band management link. A signal received on an antenna ( 300 ) is split to provide signal detection in a detection and control unit ( 385 ) wherein detection is performed by detectors ( 370, 371 ) filters ( 375, 376 ), converters ( 380, 381 ) and a processor ( 385 ). Delay is added using delay lines ( 360, 361 ). The in-band signal envelope may be modulated with variable gain amplifier ( 330 ) and demodulated with detectors ( 370, 371 ) to establish the management link with higher protocol layer capability. Alternatively, a modern function at least partially compliant to 802.11 modulation may be used in parallel with the frequency translating repeater.

Description

[0001] Cross References to Related Applications [0002] This application is related to, and claims priority from, pending U.S. Provisional Application No. 60 / 420,449, filed October 24, 2002, and further to PCT application entitled "WIRELESSLOCAL AREA NETWORK REPEATER" PCT / US03 / 16208 is relevant, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to wireless local area networks (WLANs), and more particularly, the present invention relates to extending the coverage area associated with WLAN repeaters using in-band communication protocols to allow repeaters and other network devices to communicate with each other using network management functions. Background technique [0004] A variety of standard protocols for wireless local area networks, commonly referred to as WLANs, are becoming popular. These include protocols such as 802.11 (as described in the 802.11 wireless standard), IEEE 802.16, IEEE 802.2...
