摘要:
A method and apparatus for allocating spectrum within a wireless communication system is provided herein. During operation, a first base station will determine a location of a UE wishing to transmit. A database will be accessed containing wireless coverage area information for base stations with overlapping coverage with the first base station. Based on this information the first base station will determine if the UE is within an overlapping coverage area of multiple base stations. Spectrum will be assigned to the wireless equipment in a guard band, based at least in part on the determination that the UE is not within the overlapping coverage area.

A method and apparatus for operation of a node within a mobile ad hoc cognitive radio network is provided. The method includes sensing at least one assigned communications channel. Sensing at least one assigned communications channel includes measuring a value of at least one parameter corresponding to the communications channel. The method further includes comparing the measured value of the at least one parameter with a set of stored values of the at least one parameter to determine a change in the measured values. Finally a sleep mode of the node is activated for a time period, wherein the time period is determined using the change in the measured values.

A communications system and method for exchanging spectrum usage information through a drop box (100) includes one or more central stations (101) that defines a region of operation. A central drop box (102) is associated with the central station (101) for providing a database of spectrum usage information. Stations (103, 105, 107) using the communications system may submit information regarding spectrum usage to the central drop box (102) that affects the region of operation (109, 115) for providing the most efficient and non-interfering uses of the frequency spectrum.

A method, wireless controller, and information processing system that define communication channel allocation. Communication channel allocation commands associated with a first network are monitored (102). The first network (102) comprises a plurality of communication frequencies assigned by the communication channel allocation commands. A set of communication frequencies are determined that have been assigned to wireless devices (108) associated with the first network (102) in response to the monitoring. A specification of unused communication frequencies within the plurality of communication frequencies are transmitted to a second network (104) in response to the determining.

The present invention provides a modem (100), method (300) and device (103) for indicating received signal strength and presence for intensity modulated binary-coded data packets with reduced recovery time in a packet data receiving system. The device includes a receiver for binary coded wireless data packets having a first band-pass processing unit, for receiving modulated electromagnetic signals and converting the modulated electromagnetic signals to binary data signals and a second band-pass processing unit, coupled to the receiver, for providing a logarithmic received signal strength indicator signal, RSSI, using a low-frequency cutoff f.sub.L2 greater than a low-frequency cutoff f.sub.L1 of the first band-pass processing unit.
摘要:
A method, information processing system, and network that expands safety network coverage for first responder safety within a building environment. Activity of at least one independent network (106) is monitored. The independent network (106) includes at least a safety network. An emergency signal is received from the at least one independent network (106). Communication between at least the safety network (106) and a First responder network (110) is automatically bridged in response to receiving the emergency signal so as to manage data control and bandwidth allocation between the safety network and the first responder network. Other networks that may also be bridged with the first responder network so as to manage data control and bandwidth allocation among the various networks include IT networks and building automation networks in order to expand first responder network coverage.

A method for priority-based admission control in a network, comprises receiving an admission request for transmitting an information flow to a network through a communication channel and determining an admissible region within a range of a channel data rate of a communication channel for an information flow in response to a priority of the information flow, where the priority of the information flow is one of a plurality of priorities of information flow. The admissible region is one of a plurality of admissible regions within the channel data rate range that correspond to different ones of the plurality of priorities of information flow, respectively, and each of the plurality of admissible regions within the channel data rate range is useable for transmitting information flow with a respective one of the plurality of priorities. Further included in the method is determining an available channel data rate of the communication channel for receiving the information flow by the network, and granting the admission request for the information flow after determining that the available channel data rate of the communication channel is within the admissible region of the channel data rate range.
