A system for channel handover includes a mobile radio device and a server storing polygon operating area information for a plurality of overlapping polygon operating areas for wireless communication. The mobile radio device receives the polygon operating area information, and determines the device location. Based on the polygon operating area information, the mobile radio device selects a first channel of operation corresponding to a channel that is available for use within a first polygon operating area. The travel of the mobile radio device is tracked to determine when the mobile radio device has exited the first polygon operating area and entered a second polygon operating area. When this occurs, the device selects a second channel of operation corresponding to a channel that is available for use within the second polygon operating area. Alternatively, the channel selection may be determined by the server and transmitted to the mobile radio device.

System and method for using geo-location and a centralized spectrum management database to enable seamless handover and geo-fencing of channel usage in wireless systems

Transferring spectrum use rights may include ascertaining information regarding available spectrum for use in wireless communications. A request for spectrum use from a spectrum user system may be matched with available spectrum. A spectrum certificate may be issued to the spectrum user system, where the spectrum certificate contains at least one spectrum-related variable under which the spectrum user system is to engage in wireless communications.

A spectral reuse transceiver-based communication system conducts communications between a master site and a plurality of remote sites using a selected portion of a communication bandwidth containing a plurality of sub-bandwidth channels. Each remote site transceiver monitors the communication bandwidth for activity on the sub-bandwidth channels, and informs a master site transceiver which sub-bandwidth communication channels are absent communication activity and therefore constitute clear channels. The master site transceiver compiles an aggregate list of clear channels from all the remote sites and then broadcasts the aggregate list to the remote sites. The master site and a remote site then conduct communications therebetween by frequency-hopping and/or orthogonal frequency multiplexing among the clear channels using an a priori known PN sequence.

A system and method for achieving enhanced CSMA/CA which improves channel availability and quality of service (QoS) in a wireless communications network. The system and method establish channels to enable communication between nodes in a communication network, based on the relationship between the average time length of message data packets and the time lengths of the request to send and clear to send messages. A node of the communication network places a data packet at a location in a queue for retransmission based on a type of information contained in the data packet if the destination node for which the data packet is intended is unable to receive the data packet. The location in the queue is indicative of a duration of time that the node will delay before attempting to resend the data packet to the destination node.

A wireless local area network (LAN) for data communications. The wireless LAN includes a packet hopping access terminal (PHAST) and a packet hopping gateway (PHG). The PHAST has a first transceiver for wirelessly communicating with a client device, and a second transceiver for wirelessly receiving data packets addressed to the client device and for wirelessly transmitting data packets received from the client device in accordance with a packet hopping protocol. The PHG has a transceiver for wirelessly receiving the data packets transmitted by the PHAST and for transmitting the data packets addressed to the client device in accordance with the packet hopping protocol, and a network interface for establishing communication with a server.

A system and method for enabling a transmitter employing signal spreading techniques to increase the data rate of the transmitted modulated signal without reducing the multi-path delay spread. Specifically, the system and method use concatenated spreading sequences to provide data modulated spread signals having increased data rates with extended multi-path delay spread. The system and method therefore removes the one-to-one relationship between the repetitive spreading code length and maximum multi-path delay spread of a data modulated spread signal, to thus increase the data rate for a given multi-path delay spread while preserving the autocorrelation and cross-correlation properties of the individual spreading sequences.
