Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider. The category of service provider may be identified and displayed on the communication device.

Abstract: A previously unknown wireless device, which may be either an access point or a station, is detected by receipt of transmissions from that device at one or more access points that are currently operating within a managed wireless network. A graphic representation of the newly detected device is displayed in a region of a user interface external to a region containing a representation of the physical environment of the managed wireless network. A user selects a number of known access points from which an estimated distance to the newly detected device is to be determined and represented. A representation is generated of an estimated distance from each one of the selected number of access points, such as those access points that are estimated to be physically closest to the newly detected device, for example on the basis of signal strength with regard to transmissions from the newly detected device received at the known access points.

If repetition is detected, the enhanced soft bits may comprise enhanced soft bits for at least a portion of level 1 region and level 3 region of the GSM SACCH block.

Abstract: In a wireless local area network including an access controller (AC) and an access points (AP), the AC transmits a functionality inquiry to the AP. Upon receiving the inquiry, the AP transmits a query response including the functional capabilities of the AP. The AC then generates a map of the functional capabilities present in the network based on the inquiry response. Conflicting or redundant functional capabilities are identified and are disabled, enabled, or reconfigured by instructions from the AC. The AC may selectively enable and/or disable functional capabilities at nodes in the network to provide a more balanced load on the network, and to provide for load sharing by allocating functionalities between and among network nodes having common functional capabilities to satisfy a variety of situations encountered in the network.

Abstract: Discloses a system to provide cellular handset operational status information to wireless carriers relating to insertion or proximity of mobile cellular handsets to a hybrid fixed wireless interface (HFWI) device. Upon handset coupling to a HFWI, by insertion of the handset into a receiving connector on the HFWI or proximity of the handset to the HFWI, the system controls the handset to update the signalling protocol to inform the wireless carrier of an interfaced and operational operation mode. In an alternative arrangement upon handset coupling to the HFWI, the HFWI instructs the handset to transmit an interfaced and operational mode of operation message to the wireless carrier. In a preferred embodiment upon removal of the handset from the HFWI, or the handset being taken out of reach of HFWI proximity sensing, the system reverts to the conventional signalling protocol indicating a non-interfaced (mobile) operation mode to the carrier.
