Abstract: A method for preventing co-channel operation with a radar system includes the steps of setting a state of a first communication channel to active, connecting to a first wireless access point on the first communication channel, passively scanning at least a second communication channel for communication from a second wireless access point, setting a state of the second channel to active if frames are received on the second channel, determining whether an elapsed time since frames were received on at least one of the first channel and the second channel has exceed a predefined value, and in response to the predefined value being exceeded for at least one of the first channel and the second channel, setting the state of a corresponding one of the first channel and the second channel to passive.

Abstract: A wireless two-way communications apparatus (700) having a radio resource manager (706) is configured and arranged to effect one or more modes of operation (203, 204, 206, and 207) as a function, at least in part, of whether the apparatus is presently operating in a power saving mode of operation (201) and/or is presently supporting an active plesiochronous communication session (202 and 205). Pursuant to one approach, when the apparatus is operating in a power saving mode of operation and presently supports such a communication session and when the apparatus further determines (301) that a wireless access point beacon or supplemental beacon is at least largely coincident with a scheduled active window of that communication session, the apparatus can determine (302) whether to facilitate rescheduling a next monitoring of the beacon or supplemental beacon and/or altering the scheduled active window itself to thereby render the beacon or supplemental beacon monitorable by the apparatus.

Abstract: In the present invention, the subscriber unit (200) obtains a set of access point identifiers and measurement opportunity information for each access point identifier. A first measurement is performed on a first access point identified from the set of access point identifiers. A current timer value is determined after completing the step of performing, and a second access point identified from the set of access point identifiers in which to perform a second measurement is selected. Selecting the second access point is based on at least the measurement opportunity information for the second access point in relation to the current timer value.

Abstract: A mobile station (204) in a wireless local area network is associated with an access point (202), which controls timing of certain transmissions, such as beacons (402). The mobile station has a timer (108) that is driven by a high frequency clock source (110) while operating in an active mode, and a low frequency clock source (112) when in a low power mode, to conserve battery charge. To prevent timing errors from significantly affecting the accuracy for the timer (108) upon transitioning from one mode to the other, access point transmits timing information to the mobile station in the course of servicing requests from the mobile station. The timing information is included in a response sequence (300).

Abstract: The invention provides an enhanced passive scanning method for a wireless local area network, including the steps of transmitting at least one of a beacon signal or a gratuitous probe response in a WLAN channel by an access point. The gratuitous probe response is a supplemental beacon signal that is transmitted at intervals between the occurrence of regular beacon signals, but contains only essential information to allow mobile station manage roaming and timing.

Abstract: A wireless station ( 114 ) is within range of more than one access point ( 120, 124 ) transmitting on the same channel. The wireless station is associated with one access point and not the other. Consequently the wireless station may receive undesired beacons ( 304 ) and desired beacons ( 302 ) on the channel. To optimize power save operation the wireless station arbitrates between a scan and shut down scanning procedure ( 708 ) and a timed window channel scanning procedure ( 724 ), depending on whether the desired beacon is the first received beacon upon waking up from a low power state at a target beacon time.

Abstract: A method and a machine readable storage for handling failures during security exchanges between a station (125) having a wireless network adapter (130) and a first access point (110) of a wireless local area network (WLAN) (105). As part of a WLAN association process, the method can include transmitting from the station to the first access point a message including a station identifier (170). A first protocol exchange timer (180) also can be started. Responsive to a timeout of the first protocol exchange timer, an association retry counter can be incremented. The WLAN association process can be restarted if the association retry counter is not greater than a retry counter threshold. If the association retry counter is greater than the retry counter threshold, the wireless network adapter can be commanded to enter sleep mode.
