Reconfigurable access point
Granted: April 28, 2009
Patent Number:
7525943
In general, one embodiment of the invention relates to a method of operation where the type of an incoming Media Access Control (MAC) frame is initially determined. Based on such determination, the MAC frame is processed locally at an access point if the MAC frame is one of a first group of MAC frames. Otherwise, the MAC frame is processed remotely at a switch communicatively coupled to the access point.
Modular radio access point
Granted: August 19, 2008
Patent Number:
7414995
In general, one embodiment of the invention is a radio access point (RAP) system adapted to a wired network. The RAP system comprises a radio access point and a switch coupled together by an interconnect. The radio access point includes components to digitally sample a detected, wireless analog signal thereby producing digital data. The digital data is placed into a frame for transmission over the interconnect. The switch includes a radio access point (RAP) component that recovers the…
System and method for positioning and calibrating wireless network devices
Granted: February 27, 2007
Patent Number:
7184770
In an exemplary embodiment, a method comprising determining locations within a site for a plurality of network devices and calibrating the network devices by each of the plurality of network devices. The calibration of each network device is performed separately and successively through the transmission of wireless signals by the access points. The quality of these wireless as measured by test receivers are mapped to detect RF interference and to adjust power level or channel assignment…
System and method for monitoring and enforcing policy within a wireless network
Granted: October 18, 2005
Patent Number:
6957067
In general, one embodiment of the invention is a air monitor adapted to a wireless network. The air monitor enforces policies followed by the wireless network even though it is not involved in the exchange of data between wireless devices of the wireless network such as access points and wireless stations.
