ARRANGEMENT FOR SYNCHRONIZING ACCESS POINTS IN WLAN USING DIRECT-SEQUENCE SPREAD SPECTRUM SIGNALING

摘要

An arrangement for providing synchronization between a number of overlapping area access points within a wireless LAN utilizes an Ethernet cable connection to transmit synchronization signals from a centralized hub/switch to each of the access points connected to the cable. The synchronization signal takes the form of a direct sequence spread spectrum (DS-SS) signal.

1. A method comprising:
generating a direct sequence spread spectrum synchronization signal at a network hub from a combination of a baseband data signal and a plurality of pseudo noise sequences including timing information for providing synchronization; coupling the direct sequence spread spectrum synchronization signal onto at least one Ethernet cable, wherein the at least one Ethernet cable couples the network hub to a plurality of wireless access points of a wireless local area network; and transmitting the direct sequence spread spectrum synchronization signal from the network hub to the plurality of wireless access points over the at least one Ethernet cable.
