Abstract: Methods for providing a client access to a channel in a meshed wireless local area network are disclosed. The methods comprise that a client in the meshed wireless local area network implement a polling based channel access methodology. The client determines that the channel is available by sensing that the channel is not busy and sends a request for access to the channel to an access point, wherein the request specifies a priority of data that is to be transmitted when the client is granted access to the channel. The client waits a time period before receiving at least one of a) a rejection of the request for access to the channel, b) access to the channel, c) modification of the request for access to the channel, and d) delay access to the channel.

Abstract: A method for providing a mobile device in a packet data network access to a channelized network is disclosed. At a gateway between the two networks, a first channelized network message that is encapsulated in a first IP data packet from the packet data network is received. The first channelized network message is retrieved and reformatted for sending over the channelized network. The gateway then receives a second channelized network message from the channelized network. An identifier of a mobile device associated with the second channelized network message is retrieved and an IP address for the identified mobile device is determined. Then, the gateway encapsulates the second channelized network message into a second IP data packet and sends the encapsulated second channelized network message to the identified mobile device in the packet data network.

Abstract: A system and methods for providing a supplicant access to a communications network are disclosed. An authenticator receives an authentication request at an authenticator (210) from the supplicant. A state is created based on the authentication request at the authenticator (210). The authentication request is relayed towards a prime authenticator (215) where the prime authenticator is connected to an authentication server. Finally, the authenticator (215) receives authentication information from the prime authenticator and fulfills the authentication request using the authentication information.

Abstract: Methods for informing a mobile device of adjacent sites in a RF communication system wherein the RF communication system comprises a first network and a second network are disclosed. A mobile device in the first network of the RF communication system updates a signaling gateway with position information of the mobile device wherein the signaling gateway interfaces between the first network and the second network and receives a list of adjacent sites in the second network from the signaling gateway.

Abstract: Methods for performing client to client communication in a wireless local area network are disclosed. At an ‘n’ tier client in the wireless local area network, a signaling message from an ‘n?1’ tier client is received wherein the signaling message comprises a first period, a second period, and a third period. Communicating with the ‘n?1’ tier client during the first period and communicating with the ‘n+1’ tier client during the third period. At an access point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does not communicate with the clients during the first period.

Abstract: Methods for delivery of multicast packets in a wireless communication system are disclosed. The methods comprise transmitting a contention free period initiation signal from an access point to the station, transmitting broadcast packets from the access point to the station, transmitting multicast packets from the access point to the station and holding the multicast packets in storage after the transmission, transmitting a contention free period end signal from the access point to the station, determining if a negative acknowledgement message has been received, retransmitting the multicast packets in response to receiving a negative acknowledgment message, and eliminating the multicast packets at a next beacon interval.

Abstract: Distributed DNS in a wireless communication network comprising broadcasting by a first node a request message to a second node is disclosed. The request message comprises a hostname of the second node. The first node forwards the request message to the second node through intermediate nodes in the wireless communication network and the second node transmits a response message to the first node. The response message comprises a MAC address of the second node.

Abstract: A method and system for wireless data transmission between at least three stations use multiple frequency bands for simultaneous channel communications. The method includes transmitting a Request To Send (RTS) packet from a first station to an intermediate second station over a first frequency band. Two Clear To Send (CTS) packets, which CTS packets include transmission timing information, are then transmitted from the second station simultaneously both to the first station and to a third station. The CTS packet sent to the first station is transmitted over the first frequency band and the CTS packet sent to the third station is transmitted over a second frequency band. A data packet from the first station is then transmitted to the second station. The third station suspends, based on the transmission timing information included in the CTS packets, any unicast transmission to the second station during the transmission of the data packet from the first station to the second station.

Abstract: A radio frequency communications system (100) includes wireless terminals (102) and base sites (104). The wireless terminals communicate with the base sites over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. The communication system has a radio frequency channel (400) with time slots (406, 408) for transmission of both delay-sensitive data, such as streaming audio and video, and non-delay-sensitive data. A method and apparatus are provided for determining whether a time slot in the radio frequency channel is to be allocated to delay-sensitive data or non-delay-sensitive data (704, 706, 708). Each packet of data transmitted over the wireless channel has a type of service field (900). The type of service field has a precedence or priority value (902) and a service type (904).

Abstract: The present invention allows a single access point (“AP”; 100) to support a plurality of devices (102, 104) operating on different frequency bands. During a first period of time, the AP initiates a contention free period at a first frequency. The AP switches from the first frequency to a second frequency, and communicates with devices operating at the second frequency. Periodically during the first period of time, the AP temporarily ceases communication with devices operating at the second frequency to initiate a contention free period at the second frequency, switch from the second frequency to the first frequency, initiate another contention free period at the first frequency, and switch from the first frequency back to the second frequency.

Abstract: In a communication system, a mobile station (104) is currently associated with a first access point (AP1). AP1 (100) receives a transmission at a first signal quality from the mobile station. AP1 also receives a first message that indicates a second signal quality at which a second access point (AP2) is receiving transmissions from the mobile station. AP1 compares the first signal quality with the second signal quality, and when the second signal quality is greater than the first signal quality, AP1 signaling AP2 (102) to initiate a handoff with the mobile station. Alternatively, prior to AP1 signaling AP2 to initiate the handoff, AP1 may take into consideration the signal quality of transmissions received by the mobile station from the access points (100, 102).
