摘要： Distributed load balancing in wireless digital networks. In a network having a plurality of access nodes with at least one wireless client connected to a first access node, the client is encouraged to move to a different access node by reducing the apparent signal strength of transmissions from the access node to the client. Apparent signal strength can be reduced by reducing transmit power, by using beam forming, antenna switching, or a combination. Other access nodes may send unsolicited frames, such as probe response frames to the client, encouraging the client to move.

摘要： Interference classification with minimal or incomplete information. Receivers in access points and in other network devices on a wireless digital network may be switched to a spectrum monitor mode in which they provide amplitude-versus-frequency information for a chosen part of the spectrum. This may be performed by performing a FFT or similar transform on the signals from the receiver. Receivers are calibrated with known interference sources in controlled environments to determine peaks, pulse frequency, bandwidth, and other identifying parameters of the interference source in best and worst case conditions. These calibrated values are used for matching interference signatures. Calibration is also performed using partial signatures collected over a short period in the order of microseconds. These partial signals may be used to detect interferers while scanning. Another aspect of the invention is to record the variation of noise floor in the presence of interference sources. Multiple interference sources may be detected. While data collection is performed in one or more APs, classification may be performed in the AP or on other systems associated with the network collecting and processing spectrum information from one or more APs.

摘要： Methods of aggregating spectrum data captured from a narrowband radio to form a spectrum covering a much wider frequency band. Frequency data, such as FFT spectrum data captured from a narrowband receiver such as an IEEE 802.11 Wi-Fi receiver are combined to display representative real-time FFT, average FFT, and FFT duty cycle data of a wideband spectrum. Data is captured from narrow band radios such as access points, station monitors, or client devices on a wireless network. A wideband spectrum may be aggregated from data captured from one or from multiple devices. Data may be stored for later analysis and display.

摘要： Multi-pattern transmission of wireless frames. A digital device contains a transmitter feeding an electronically steerable antenna system where the radiation pattern produced by the antenna system may be selected. Different antenna radiation patterns are used in transmitting a first portion of a wireless frame and a second portion of a wireless frame in a wireless digital network. In one embodiment, a first portion of a wireless frame is transmitted using a wide radiation pattern while the second portion of the frame is transmitted using a second radiation pattern. Switching among radiation patterns in the electronically steerable antenna system may be accomplished by switching between antenna types, such as an omnidirectional antenna for the wide pattern, and beam-steered or sectorized antennas for the second radiation pattern. Beam-forming and/or phasing approaches may also be used. The first and second portions of the frame may be transmitted at different power levels. For high throughput (HT) frames such as IEEE 802.11n frames, the non-HT preamble and L-Sig are taken as the first portion of the frame, with the HT-Sig, HT-training and HT-data portions of the frame taken as the second portion of the frame, transmitted using a narrower radiation pattern.
