Abstract: 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.

Abstract: In a wireless communication network having a plurality of devices operating at different data rates that contend for access to the network, an apparatus is provided that assigns network access parameters so as to control throughput on the network.

Abstract: In a wireless communication network having a plurality of devices operating at different data rates that contend for access to the network, a method is provided that assigns network access parameters to one or more of the devices so as to control throughput on the network. Examples of network access control parameters are the maximum data packet size and the contention window size. Generally, the network access control parameter for slower data rate users is configured so that they do not occupy the network a disproportionate amount of time compared to faster data rate users.

Abstract: Interference mitigation or collision avoidance systems and procedures to allow different wireless local area network (WLAN) communication protocols to co-exist in the same frequency band, such as an unlicensed frequency band used for short-range wireless communications. The procedures ensure substantial throughput of information carried by signals of each WLAN protocol while preventing collisions between signals of different protocols.

Abstract: A wideband radio transceiver system that features a wideband RF section and a flexible and scalable baseband signal processing section. The transceiver system architecture has configurable baseband processing to process signals for multiple communication protocol standards, or multiple instances of the same communication protocol standard, that operate over the same frequency band. Optional additional features include a transmit carrier suppressor and transmit interference canceller to suppress the effects of a transmit signal on receive signal processing when signals are being transmitted and received simultaneously.

Abstract: A system and method that minimizes power consumption in wideband radios by dynamically adjusting the sampling rates of an analog-to-digital converter to the minimum sampling rate required to support the operation in a wideband mode and operation a narrowband mode. The sampling rate is controlled according to an operating mode whereby the sampling rate for a wideband operating mode is greater than the sampling rate for a narrowband operating mode. The wideband operating mode is a mode in which energy for an entire frequency band is received and sampled by the analog-to-digital converter and the narrowband operating mode is a mode in which only a portion of the entire frequency band is received and sampled by the analog-to-digital converter.
