A system for automatically selecting communication frequencies for wireless communication devices (e.g., base unit, access point, and controller) being added to an existing wireless network. The operating frequencies, evaluated signal strength, and loads are used in determining the most suitable operating frequency. This automatic selection process eliminates the problems inherent in manual frequency selection.
The present invention is a method and apparatus for providing a pseudo random sequence for a spread spectrum system that prevents interception and provides real estate and power consumption efficiency. A pseudo random sequence may be created in real-time by associating a pseudo random sequence of a channel location of the carrier frequency at an instant in time. For example, the entire band of the spread spectrum system may be scanned to detect a channel with a low received signal strength. The location of the channel, or the actual frequency of the channel, could be associated with a particular pseudo random sequence to create a hop set for frequency hopping. Additionally, the location of a characteristic of the spread spectrum system, such as a noise characteristic, could be utilized to determine a content of a pseudo random sequence.
A method for WLAN signal strength determination comprises receiving a WLAN RF signal; converting the WLAN RF signal to a voltage proportional to the signal; comparing the voltage to a first reference voltage; and outputting data corresponding to WLAN RF signal strength if the voltage is greater than the first reference voltage.
A wireless transceiver capable of selectively receiving and transmitting as a direct sequence spread spectrum system or as a frequency hopping spread spectrum system is disclosed. The system is particularly suitable for use in a cordless telephone system. The transceiver includes components for both direct sequence spread spectrum transmission and reception and for frequency hopping spread spectrum transmission and reception.
A wireless network configuration device can include a first communication port configured to access a plurality of nodes positioned in a geographic area, a first storage unit configured to store statistical information from the plurality of nodes with respect to communication between the plurality of nodes and the at least one wireless devices. In addition, the wireless network configuration device can include a processor configured to determine an optimized configuration with respect to the plurality of nodes based on the statistical information, and a second communication port configured to provide data with respect to the optimized configuration to the plurality of nodes, wherein the plurality of nodes are adjusted based on the data.
In a wireless local area network, transmissions exchanged between a station and an access point is received using a detector located adjacent to the station. The received transmissions are analyzed to determine the state of the station, where the state of the station indicates whether the station has authenticated and/or associated with the access point in the wireless local area network.
