| 20100119002 | MIMO ANTENNA SYSTEM - A wireless local area network (“WLAN”) antenna array (“WLANAA”) includes a circular housing having a plurality of radial sectors and a plurality of primary antenna elements configured as Multiple-Input, Multiple-Output (MIMO) antennas. Each primary antenna element, which includes multiple antennas connected to a single radio, being positioned within a radial sector of the plurality of radial sectors. | 05-13-2010 |
| 20100039308 | System and method for detecting radar signals in wireless communications access points - A system and method for providing radar signal detection in a communications system. In an example method, a raw energy detect signal is received and analyzed to determine if the raw energy detect signal contains a valid radar pulse. A bit is stored in a bit sequence storage device such that the bit has a first value if a valid radar pulse was detected or a second value indicating that a valid pulse was not detected. A set of bits in the bit sequence storage device are accessed to determine if a plurality of waveform-indicating locations in the bit sequence storage device includes valid pulses. In another aspect of the invention, a system detects a radar signal in a communications device. The system includes a pulse detector to detect pulses in a raw energy signal having a pulse width within a predetermined minimum and maximum pulse width. The system includes a frequency detector having a bit sequence storage device to store the bits output by the pulse detector. The frequency detector detects whether the detected pulses conform to a waveform type by determining if the bits are stored in the bit sequence storage device in waveform-indicating locations. | 02-18-2010 |
| 20090059875 | NODE FAULT IDENTIFICATION IN WIRELESS LAN ACCESS POINTS - A wireless access point array having a plurality of access point radios, a monitor radio and an array controller. The array controller includes processes, methods and functions for verifying the operation of the access point radios. The access point radios may be verified by attempting to establish a data connection between the monitor radio and each of the access point radios. | 03-05-2009 |
