A method for communication includes transmitting a first uplink message from a first remote node () to a central node () in a wireless communication system according to a first frequency hopping scheme, and transmitting a second uplink message from a second remote node to the central node in the wireless communication system according to a second frequency hopping scheme, different from the first scheme. Both the first and the second uplink messages are received and processed at the central node.

Wireless communication system

An embodiment of the present invention provides a method to resolve a location of nodes operating in a wireless network, comprising using a wireless network infrastructure of the wireless network to determine the location of the nodes by each location aware node distributing location information within the wireless network such that each node may learn its location directly from the infrastructure of the network.

Techniques for autonomous wireless network infrastructure assisted location resolution

A method, apparatus and a wireless communication system to reduce power consumption of a wireless Multicomm device by using a location-aware scanning for detecting WLAN networks. The location awareness is obtained from a base station identifier of a wireless wide area network (WWAN) and is based on a preconfigured database that associates WWAN BS IDs with potential WLAN networks.

Method apparatus and system for reducing power consumption of a wireless device

An embodiment of the present invention provides an apparatus, comprising a network adapter capable of combining more than one wireless communication technology (comm) for wireless communication in a wireless network, wherein the apparatus includes a network detection phase implemented by doing a full scan of one comm followed by one or more additional comm scans; and wherein the network adapter breaks a scan into buckets, and alternates between different scanning buckets of different comms to provide faster scanning, connection time and handover from one wireless technology to another wireless technology.

Method and apparatus to shorten the duration of initial network selection and handover decisions in multicomm platforms by utilizing alternate fragmented scanning

A method and apparatus of coordinating operation of two or more subsystems implementing different wireless communication protocols is disclosed. The method comprises coordinating operation of a first subsystem implementing a first wireless communication protocol and at least one other subsystem implementing at least one other wireless communication protocol by merging requests from the first subsystem for pre-scheduled access and real time access into a single request for access for the first subsystem. The method comprises merging requests from the at least one other subsystem for pre-scheduled access and real time access into a single request for access for the at least one other subsystem and arbitrating between the single requests for access for each subsystem to allocate access to the first subsystem and/or the at least one other subsystem.

Method and apparatus for concurrent operation of wireless communication protocols

A method and apparatus of reducing interference between wireless communication protocols is disclosed. The method comprises reducing interference between a first wireless communication protocol operating in a first frequency band and a second wireless communication protocol operating in a second frequency band by generating noise to cause interference with one or more frequencies in the second frequency band and performing Adaptive Frequency Hopping (AFH) in the second wireless communication protocol to avoid the one or more frequencies in the second frequency band in which interference is caused by the noise.

Method and apparatus for non-cooperative coexistence between wireless communication protocols

Concurrent WIMAX and GSM operation is facilitated in a user device by coordinating for WiMAX absence periods during WiMAX frames that may conflict with corresponding GSM frames.

Method and apparatus for concurrent WiMAX and GSM operation

A method and apparatus of coordinating operation of subsystems implementing different wireless communication protocols is disclosed. The method comprises coordinating operation of a first subsystem implementing a first wireless communication protocol and at least other subsystem implementing at least one other wireless communication protocol by arbitrating between conflicting real time requests for access from the first subsystem and the at least one other subsystem based on a respective type and priority of the requests.

Method and apparatus for multi-radio traffic arbitration in wireless communication protocols

A method and apparatus of reducing interference between subsystems implementing wireless communication protocols is disclosed. The method comprises reducing interference in a first subsystem implementing a first wireless communication protocol operating in a first frequency band caused by a second subsystem implementing a second wireless communication protocol operating in a second frequency band, the second wireless communication protocol employing Adaptive Frequency Hopping (AFH), the method comprising calculating one or more frequencies to be avoided by the second subsystem on the basis of one or more frequencies in use by the first subsystem.

Method and apparatus for cooperative coexistence between wireless communication protocols

This invention discloses a frequency hopping cellular LAN system including a LAN, a plurality of access points each operatively connected to the LAN, the plurality of access points including at least a first access point and a second access point, and a station which communicates with at least some of the plurality of access points using frequency hopping spread spectrum wireless communication, wherein the first access point and the second access point each communicate with the station using a first and second predetermined sequence of frequencies respectively, and wherein, during a neighbor beacon interval, the second access point communicates with the station using the first predetermined sequence of frequencies, and wherein the station chooses an access point with which to communicate based, at least in part, on a transmission received from the second access point during the neighbor beacon interval. A method for choosing an access point with which to communicate in a frequency hopping cellular LAN system is also disclosed.
