摘要： At a wireless device operating in an unlicensed frequency band, energy received at a plurality of antennas is analyzed to detect interference on a channel in the unlicensed frequency band. The type of interference detected in the received energy is determined. Parameters are then generated for a nulling filter based on the type of interference detected in the received energy. The nulling filter is applied to the received energy at the plurality of antennas to produce a spatially filtered output. The spatially filtered output is evaluated to determine whether to send a transmission on the channel in the unlicensed frequency band.

摘要： Techniques for monitoring radio frequency (RF) activity in a frequency band where licensed spectrum service is occurring. One or more monitoring devices are deployed at one or more locations in the coverage area of a licensed spectrum service provider. For example, the monitoring device may be integrated into a base station of a licensed spectrum service provider. Each monitoring device receives RF energy and detects whether the radio frequency energy contains activity not associated with the licensed spectrum service provider and whether there is a violation of a secondary usage policy.

摘要： A system, method, software and related functions are provided for managing activity in a radio frequency band that is shared, both in frequency and time, by signals of multiple types. An example of such a frequency band is an unlicensed frequency band. Radio frequency energy in the frequency band is captured at one or more devices and/or locations in a region where activity in the frequency band is happening. Signals occurring in the frequency band are detected by sampling part or the entire frequency band for time intervals. Signal pulse energy in the band is detected and is used to classify signals according to signal type. Using knowledge of the types of signals occurring in the frequency band and other spectrum activity related statistics (referred to as spectrum intelligence), actions can be taken in a device or network of devices to avoid interfering with other signals, and in general to optimize simultaneous use of the frequency band with the other signals. The spectrum intelligence may be used to suggest actions to a device user or network administrator, or to automatically invoke actions in a device or network of devices to maintain desirable performance.

摘要： A system and method for classifying signals occurring in a frequency band. One or more characteristics of one or more signals in the frequency band are detected using any suitable technology, such as a device that can generate characteristics of signal pulses detected in the frequency band. Data pertaining to the signal pulses is accumulated over time. The accumulated signal data is compared against reference data associated with known signals to classify the one or more signals in the frequency band based on the comparison. The accumulated data may include one or more characteristics selected from the group consisting of: pulse center frequency, pulse bandwidth, pulse duration, time between pulses and number of different active pulses, and wherein the reference data associated with each of a plurality of known signals comprises one or more characteristics selected from the group consisting of: pulse center frequency, pulse bandwidth, pulse duration and time between pulses. The accumulated signal data is compared against the reference data, and depending on the degree of match with reference data, a signal can be classified. Additional levels of signal classification processing may be performed.

摘要： Techniques are provided to reduce or restrict the bandwidth consumed by multicast video streams on wireless links, such as wireless IEEE 802.11 links. At a central multicast video transcoder apparatus configured to communicate with one or more access point devices operating in a wireless local area network, one or more multicast video streams are re-encoded the one or more multicast video streams to produce a corresponding one or more wireless-friendly multicast video streams that have a reduced bandwidth from a bandwidth of the received multicast video streams. The one or more wireless-friendly multicast video streams are thus adapted for wireless transmission by access point devices to wireless client devices in the wireless local area network. The one or more access point devices receive the one or more wireless-friendly multicast video streams and process the one or more wireless-friendly multicast video streams depending on conditions in a radio channel used by the access point device. The access point devices then wirelessly transmit the one or more wireless-friendly multicast video streams to one or more client devices in a corresponding multicast group.

摘要： A system and method are provided for managing communication with a plurality of wireless client devices operating in a radio frequency band shared by other types of devices, comprising a step of controlling at least one parameter associated with radio communication with each of the plurality of wireless devices based on the radio frequency environment associated with each corresponding one of the plurality of wireless client devices. Spectrum profile information describing the radio frequency environment (activity in the frequency band) at a wireless client device is sent to the wireless base station device (where the parameter controls are made) from either a wireless client device or another radio device in the proximity of one or more wireless client devices that is capable of generating the spectrum profile information. The spectrum profile information may include information identifying signals that are occurring in the frequency band in the proximity of a wireless client device. Examples of parameters that may be controlled at the wireless base station device include packet fragmentation threshold (the length of a data packet), transmission data rate and transmission scheduling (synchronizing a transmission to quiescent intervals of one or more periodic interfering signals).
