摘要： Operation of a mobile voice client utilizing a WLAN for access is enhanced by controlling the rate at which transmission power is changed by the access point with which the mobile voice client is associated. The access point calculates a target transmit power level based at least in-part on the distance to the nearest fixed position wireless device and the distance to the mobile voice client. The access point then determines whether the target transmit power level differs from a current transmit power level. If the target transmit power level is greater than the current transmit power level, the current transmit power level is increased at a first controlled, non-instantaneous rate such as 1 dB per second. If the target transmit power level is less than the current transmit power level, the current transmit power level is decreased at a second controlled, non-instantaneous rate such as 1 dB per second.

摘要： A wireless access point is operable to execute background scans of alternate channels by tuning to the alternate channel for short periods of time, thereby generating sub-windows of data. The sub-windows are calculated to have timing and duration that avoid disruption of communications on the active channel. Multiple background scan sub-windows are used to assemble a virtual target window of the alternate channel, e.g., a 100 mSec window, during which any periodic beacon within range might be expected to be received. The data such as beacon information is employed to generate a table ranking the alternate channels in terms of viability for communications.

摘要： When a station is within range of at least one AP that advertises load information and at least one AP that does not advertise load information, the station selects the best AP in terms of probable data rate. The probable data rate is determined based on signal strength and mode by indexing into a predefined table or by utilizing an algorithm. The selection may be skewed in favor of APs which advertise load information.

摘要： A system and method for Access Point (AP) channel selection based upon a Channel Quality Index (CQI) is described. The Channel Quality Index (CQI) is a value which quantifies a transmission quality of a channel. The transmission quality is evaluated based on a combination of different types of measured interference in the channel. In one embodiment the different types of measured interference include co-channel congestion, adjacent channel interference and in-band interference. The CQI is a value derived from the measurements, and for example may be a sum of all of the measurements. Each AP of the present invention determines the CQI of potential transmission channels, and selects a channel for use which has the ‘best’ CQI; for example if the CQI is a sum of all measured interferences, the ‘best’ AP is the one with the lowest CQI

摘要： Potential alternate channels in a wireless network are periodically analyzed and ranked in terms of interference. The best ranked alternate channel is selected as the new operating channel if a decision is made to move from the current operating channel to an alternate channel. Because the potential alternate channels are pre-ranked, the move to the new channel can be executed relatively quickly, and with reduced risk of encountering unacceptable interference conditions. Various ranking categories may be used, including but not limited to a first category that is relatively free of interference, a second category that has some interference but will support degraded communications, and a third category that has an unacceptable level of interference. Within a given rank, preference may be given to channels that were most recently analyzed and ranked.
