摘要:
A system and method for evaluating at least one communication link between a transmitting node (102, 106, 107) and a receiving node in a communications network (100), such as a wireless ad-hoc communications network (100) in accordance with the 802.11 standard. The system and method perform the operation of assigning respective link quality values to the respective communication links based on a transmit power level (TPL) value at which the respective data packets were transmitted by the transmitting node (102, 106, 107) over the respective links, a received sensitivity (RS) value of the receiving node (102, 106, 107) receiving the data packets, and a receive signal strength indication (RSSI) value provided by the network (100) for each respective link. The system and method can examine a content of a data packet being sent between the two nodes (102, 106, 107) to determine the TPL, and can receive the RSSI value from a physical layer of the communications network (100). Accordingly, the system and method can determine which link that additional data packets are to be sent by the transmitting node (102, 106, 107) to the receiving node (102, 106, 107) via the communication link based on the link quality values. Specifically, the link having the highest link quality value is selected.
摘要:
Spectrum asset class determination is dynamically assessed so that a radio device may use a more preferred one of licensed spectrum or unlicensed spectrum for the specific wireless communications application of the radio device. Licensed spectrum, in addition to unlicensed spectrum, may be made available to preferred radio devices by validating that the radio system has an equipment ID and a secondary ID that authorizes the use of the licensed spectrum by the radio system.
摘要:
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.

Disclosed are techniques for managing situations where spectrum use by one party is preempted by spectrum needs of another party. A revocation may be sent from a spectrum management system to secondary radio systems that are impacted by the presence of priority radio system. Remedial action may be taken if an acknowledgement of the revocation message is not received from a secondary radio system. Also, the secondary radio systems may transmit keep-alive messages to monitor operation of the communication pathway for the revocation messages.
摘要:
A communication system where radios without a normally available communication pathway to a spectrum management system (referred to as spoke radio devices) communicate with the spectrum management system by joining a network established by a hub radio device that has a prior registration with the spectrum management system. Once joined, the spoke may seek registration with the spectrum management system and, if appropriate, obtain a spectrum allocation from the spectrum management system. Also, once registered, spoke radio devices may form a network of their own.

摘要:
An ad-hoc, peer-to-peer radio access system having a series of remote terminals, where each remote terminal is capable of forming a link, or hop, of the routing of a call made by one of the series of terminals. The status of the battery of each terminal which may potentially form part of the routing path of a call is reported to other terminals, whereby the routing path for a call will be decided also based on the status of the battery-charge of each terminal along the routing path.

摘要:
A system and method for broadcast reception management. In some embodiments, a database is used to determine the available broadcasts and associated channel numbers for a given location. In other embodiments, a station list is determined for a specified broadcast, the station list comprising a first channel of a first station on which the specified broadcast is broadcast at a first location and a second channel of a second station on which the specified broadcast is broadcast at a second location. The communication circuitry of the wireless electronic device is tuned in accordance with the station list to the first channel in the first location to receive the specified broadcast. The communication circuitry is retuned to the second channel in the second location to continue reception of the specified broadcast.
