摘要： The disclosure concerns a communication system where adaptive antenna systems with algorithm are used to provide improved channel selection management in Wireless Local Area Network (WLAN) and other multi-node communication systems. The adaptive antenna systems can be integrated into multiple nodes of a communication network, such as access points used in WLAN, and multiple radiation modes generated and tracked to determine optimal mode for access point to client communication links to assist in channel selection across the nodes in the network. Adaptive antenna system modes are selected and Signal to Noise Ratio (SNR) is measured across available frequency channels to determine channels to assign per access point along with radiation modes to be implemented that results in improved SNR for the communication links established in the network.

摘要： A device includes a plurality of antennas, including one or more active antennas, the antennas being configured in one of a plurality of possible configurations to achieve operation in WAN, LTE, WiFi, or WiMax bands, or a combination thereof. In some embodiments, a passive antenna is utilized with lumped loading to fix the antenna tuning state. A primary and auxiliary radiator can be included in the device and configured for WAN/LTE bands, while additional antennas can be incorporated for WiFi and WiMax bands. Various antenna configurations incorporate the antenna having multiple coupled regions.

摘要： An antenna system for use with a media device is provided. The antenna system includes a multi-mode active antenna configurable to operate in a plurality of modes. Each mode of the plurality of has a distinct radiation pattern. The antenna system includes a supplemental tuner that is separate from a primary tuner associated with the media device. The antenna system includes a switching device movable between at least two positions to selectively couple the active antenna to the supplemental tuner. When the switching device is in a first position, the active antenna is coupled to the supplemental tuner. When the switching device is in a second position, the active antenna is coupled to the media device.

摘要： A tunable filter is described where the frequency response as well as bandwidth and transmission loss characteristics can be dynamically altered, providing improved performance for transceiver front-end tuning applications. The rate of roll-off of the frequency response can be adjusted to improve performance when used in duplexer applications. The tunable filter topology is applicable for both transmit and receive circuits. A method is described where the filter characteristics are adjusted to account for and compensate for the frequency response of the antenna used in a communication system.

摘要： A communication system utilizing reconfigurable antenna systems is described where beam steering and null forming techniques are incorporated to limit the region or volume available for communication with client devices. The communication system described restricts communication to defined or desired area and degrades signal strength coverage outside of a prescribed region. An algorithm is used to control the antenna system to monitor and control antenna system performance across the service area. This antenna system technique is applicable for use in communication systems such as a Local Area Network (LAN), cellular communication network, and Machine to Machine (M2M).

摘要： Example aspects of the present disclosure are directed to front end modules for use in communication systems. In one example aspect, a front end module can include a receive path. The receive path can include a low noise amplifier. The receive path can include an analog to digital converter (ADC) circuit operable to receive an analog signal from the low noise amplifier and convert the analog signal to a digital RF receive signal. The receive path can include an ADC post processing circuit operable to process the digital RF receive signal in the digital domain. The front end module can include a transmit path. The transmit path can include a digital to analog converter circuit operable to convert the digital RF transmit signal to an analog RF transmit signal. The transmit path can include a power amplifier.

摘要： A communication system is provided, including an antenna, a matching network coupled to the antenna, a controller configured to control the matching network, and a look-up table coupled to the controller. The look-up table includes characterization data according to frequency bands and conditions. The controller is configured to refer to the look-up table to determine optimum impedance for a frequency band selected under a condition detected during a time interval, and adjust the matching network to provide the optimum impedance.

摘要： A communication system is described where multiple communication networks are simultaneously accessible from a plurality of fixed and/or mobile communication devices. A Master and Slave hierarchy is implemented among the communication devices to improve communication properties on one or multiple networks. A network system controller is implemented to select the network with optimal communication characteristics for subsets of communication devices as well as assigning Master status to a communication device within these subsets.
