Abstract: A system and associated method provides for a wireless local area network (WLAN) that permits mobile units to communicate with an external, wired network. Nodes in the WLAN include multiple components, such as a base module, antenna module, and one or more wireless modules. Indeed, this system can employ two or more wireless modules that employ different short-range wireless protocols, such as IEEE 802.11-type and Bluetooth protocols. The nodes may perform self-discovery to determine modules within the node and associated functionality, as well as identify neighboring nodes to thereby establish a mesh-type network. Nodes can be configured to provide connectivity to the wired network, while others (access points) communicate wirelessly with mobile devices. The nodes may then be interconnected wirelessly, or via wires.

Abstract: Disclosed embodiments include a method performed by a network access point, such as a short-range wireless communications switch or Bluetooth base station unit, to provide a neighbor list for neighboring short-range wireless communications switches or network access points in a communications network. The method includes, at the short-range wireless switch, sending at least one signal to neighboring wireless devices, wherein sending the signal is done without assistance of a mobile unit or a system controller for the communications network. The method further includes receiving a response signal from at least one neighboring short-range wireless switch, and identifying the one neighboring short-range wireless switch based on the received response signal. Additionally, the method includes providing a neighbor list that identifies the one neighboring short-range wireless switch. Numerous alternative embodiments are also described.

Abstract: The disclosure includes a method of and associated system for placing nodes (104-109) in a wireless local area network (WLAN). The method includes receiving user-specified parameters regarding the network. The parameters can include a layout of a building or other space, and requirements for the WLAN. An algorithm then employs these parameters to automatically create an optimized layout of multiple wireless access points (104-109) for the WLAN. The method can display the layout and provide various types of information to the user.

Abstract: A system and method for arbitrating among frequency-hopping spread spectrum communication systems are provided herein. An arbitrator calculates and compares hop frequencies for the communication systems of an area or network using frequency generation parameters received from the communication systems. The comparison identifies impending transmission collisions and collision frequencies for transmission time slots. The arbitrator then selects one of the radios associated with an impending collision to transmit, and suppresses or disables transmissions by non-selected radios during the same transmission time period for that frequency. Thus, the arbitrator minimizes bandwidth lost to co-channel and adjacent channel collisions by reducing or eliminating this mutual interference among the communication systems.

Abstract: In a network, a method is disclosed for wirelessly exchanging communications with at least one mobile unit. The network includes first and second base stations units coupled to the network, and may include a system controller. The method includes: receiving a communication signal from the second base station unit, wherein the first and second base station units are configured to employ a wireless communications protocol, and wherein the wireless communications protocol does not provide for handoff of communications links between base station units; at the first base station unit, determining if the second base station unit has been synchronized based on the communication signal; at the first base station unit, if the second base station unit is synchronized, then synchronizing an internal clock based on the synchronized second base station, wherein the synchronizing is performed without assistance from a system controller.

Abstract: Various aspects of a method and system for indicating the link quality between wireless base station units are presented. The establishment of a wireless network involves the placement of and communication between several base station units. To facilitate the operational capability of such a wireless network, a method for continuously displaying the quality of the links between these base station units is introduced. The method provides each base station with the information necessary to individually display the quality of the links between itself and its neighboring base stations. The displays can take on a variety of formats. Additionally, link quality of neighboring base stations can be collected by a central controller which can process the information and create a grid showing the link quality throughout the wireless network.
Abstract: Disclosed is a system and method for wirelessly exchanging communications with at least one mobile unit in a network that includes base stations units. The method includes receiving a wireless communication from the mobile unit, where the wireless communication is under a wireless communications protocol that does not provide for handoff of communications links between base station units. The method also includes obtaining a unique session identifier for the communication with the mobile unit, and establishing a communications link with the mobile unit, where the communications link includes link context data associated with the mobile unit. The link context data associated with the mobile unit is identified at least in part based on the unique session identifier.
