Abstract: This invention describes systems and methods for combining the Wireless Local Area Network (WLAN) infrastructure and Wireless Intrusion Prevention Systems (WIPS) by leveraging a common radio platform equipped with more than one WLAN radio and a unified management system. The invention provides all the benefits of the WLAN, without sacrificing the 24×7 dedicated security monitoring and performance troubleshooting available from an overlay WIPS system, while reducing the deployment cost and management complexity, by sharing a common hardware platform for the WLAN Access Point (AP) and WIPS sensor and leveraging an integrated management system.

Abstract: Migrating from a legacy spectrum allocation to a target spectrum allocation can be accomplished by adding new access points and, at a selected time, activating the new access points and deactivating the legacy access points with a remote network manager. Alternatively, the new access points can initially support legacy channels and at a selected time be reconfigured to support only the target channels. Alternatively, the new access points are initially activated in a mode which supports only a subset of the target channels and at a selected time reconfigured to support only the target channels. A remote network manager may be employed to remotely monitor, reconfigure, and trigger activation and deactivation of access points in support of the technique. New access points adapted to respond to inputs from the remote network manager further facilitate the invention.

Abstract: 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.

Abstract: A pre-scan interval including three states is employed to synchronize access points and facilitate power control to facilitate initial channel selection where a group of nearby access point are contemporaneously initialized. In State 1 the access point is operable to transmit pre-scan frames which include device ID, and to listen for pre-scan frames transmitted by other access points. When a pre-scan frame is received, the received power level and device ID are noted and used to construct a table. The access point normally remains in State 1 until a minimum number of frame samples have been received from each access point that has been heard, and a minimum pre-scan time has elapsed. State 2 provides synchronization of transition of the access points between State 1 and State 3. When the access point is in State 2, it transmits pre-scan frames with a sync-mark bit set to indicate that the access point is in State 2.

Abstract: A port on a network device engages in auto-negotiation on a network link during a first operational state to select a transmission mode, either half duplex or full duplex. If half duplex operation is selected, the port commences half duplex operation in a second operational state. During the second operational state, the link is monitored for an error condition indicating that another network device attached to the link may not be operating in a half duplex mode. This error condition includes the occurrence of excessive collisions or late collisions. When the error condition is detected, the port commences full duplex operation in a third operational state, based on the presumption that device at the other end of the link may be configured for fixed full duplex operation. If proper operation ensues, the port remains configured for full duplex transmission.

Abstract: In a wireless network an access point and/or wireless end device is operable in response to interference from another device to capture a sample of the interference, determine whether the interference originates from a known type of device, and prompt remedial actions based on whether the interference originates from a known type of device. The access point may include a table of known interference signatures and a table of counter measure plans, each interference signature being associated with a particular counter measure plan. Remedial actions include changing to an alternate operating channel and/or changing signal transmission characteristics.

Abstract: Seamless migration of an AP/STA link across channels to compensate for a changing RF environment is achieved by forecasting alternate AP communication channels to an STA prior to loss of connectivity on the link. The AP, when identifying a preferred communication channel, also identifies an alternate communication channel, and communicates this alternate channel to a coupled STA. In the event that communication between the AP and the STA is lost, the STA can quickly predict the new location of the AP, and migrate to the new channel without loss of communication state. The AP is not required to communicate to any STA that it has switched stations. Rather, the fact that the AP has switched is inferred at the STA by the inability of the STA to communicate with the AP. Thus the present invention may be used to preserve link state when a communication channel used by the AP/STA link is blocked.

Abstract: 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.

Abstract: In a wireless network having an access point and at least one wireless end device, the access point is operable to differentiate between normal communications and interference from another device in order to capture a sample of the interference, determine whether the interference originates from a known type of device, and prompt remedial actions such as moving communications to a distant channel, increasing transmission power, changing data rate, and packet fragmentation based on whether the interference originates from a known type of device. Interference pulse duration may be used to at least initially narrow the possible sources of interference. Pulse period may be employed to differentiate between interference sources which exhibit similar pulse duration. If pulse duration and period are not sufficient to identify the interference source then other characteristics may be examined, such as pulse waveform, roll off and period in relation to local power frequency.

Abstract: In a wireless network having an access point and/or at least one wireless end device, the access point and/or end device is operable to differentiate between normal communications and interference from another device in order to capture a sample of the interference, determine whether the interference originates from a known type of device, and prompt remedial actions based on whether the interference originates from a known type of device. One technique for differentiating between interference and normal communications is to induce a quiet interval during which normal communications are ceased. Another technique is to employ a parallel demodulation engine. The quiet interval may be assembled from temporally non-contiguous quiet gaps between normal communications. For interference sources which exhibit a pulse waveform the interference sources are analyzed based on pulse period and duration.
