Battery

Light source

An application-specific integrated circuit and related network switch are disclosed. The integrated circuit includes switch circuitry for receiving a 802.11 wireless data frame and forwarding it to a predetermined port. Inspection circuitry is provided for inspecting attributes of the data frame. Decision circuitry is provided for instructing the switch circuitry to forward the data frame based on the attributes, both 802.3 wired and 802.11 wireless.

Wireless-aware network switch

A system for locating a client in a wireless network. The system includes at least three access points. Each access point is adapted to wirelessly communicate with a client having a location using packeted data, be placed in wired data communication within a selected data network; and to share a common precise time reference using the selected data network. The system further includes a switch adapted to translate the relative position of the access points based on a shared common precise time reference and to calculate the location of the client based on a transmission from the client.

System and method for clock distribution and synchronization and radio location

A method and apparatus for managing a wireless local area network are disclosed. The network includes one or more wireless access points, each including a radio frequency assembly having a variable power output, and an antenna assembly for transmitting and receiving wireless signals. A microcontroller is included for sending a transmission characteristics signal to the wireless local area network. A network manager is included for receiving the transmission characteristics signal and selectively controlling the variable power output of the radio frequency assembly to a predetermined power level.

Wireless network management with antenna control

In one embodiment, a powered device is configured to determine module population and the appropriate power requirements for installed modules. The power requirements can be communicated to the power sourcing equipment for the powered device. Optionally, the powered device can receive data representative of available power from the power sourcing equipment and the powered device is responsive to operate accordingly.

Reporting power requirements of a powered device

In a wireless LAN (WLAN), methods, apparatuses and systems directed to facilitating configuration of a wireless network is provided. According to one implementation of the present invention, sensors are used to collect data associated with locations and other properties of access points of the wireless network. The collected data can then be used to assist in automatically configuring one or more aspects of the wireless network. In some implementations, the collected data can be used to dynamically re-configure the wireless network in real time. According to another implementation of the present invention, location computation mechanisms are used to collect data associated with the location of one or more wireless clients, and the data is used to dynamically adjust one or more radio frequency (RF) coverage maps in real time. The revised RF coverage maps can then be used to re-configure one or more operational parameters of the wireless network. Implementations of the present invention provide many advantages, such as automating the configuration of the wireless network in real time and facilitating network management decisions.

Automated configuration of RF WLANs via selected sensors

A method for controlling cell size associated with an access point that has a receive sensitivity and an output power. The method includes changing a start of packet threshold and/or a clear channel assessment threshold to vary the cell size of the access point.

High density WLAN system

A system for measuring output power from an antenna. A sensor receives a sample of wireless signals from the antenna and communicates data about the signal back to the transmitter in a manner such that the antenna pattern is undisturbed. An optical coupler, e.g., fiber optic, is used to send data from the sensor to the transmitter. Power for the sensor can be derived parasitically from the wireless signal or can be provided to the sensor optically.

Isolated sensor for an antenna

A method for radar protection. The method includes recording energy events and calculating differences in recorded energy events to determine pulses. The method further includes sorting intervals between pulses into histogram bins, each bin representing a range of time intervals between two pulses, each pulse indicative of a radar frequency and limiting network traffic on a frequency based on a selected bin count.

Radar protection device for wireless networks

Wireless-aware network switch and switch ASIC

In an example embodiment, a time of arrival circuit coupled to a wireless transceiver configured to determine a time of arrival of a wireless signal. The time of arrival circuit is operative to perform a coarse-scale frequency domain correlation of the actual samples with a predetermined ideal sample. The time of arrival circuit determines a maximum coarse correlation coefficient. The time delay circuit is operative to determine a plurality of fine correlation coefficients by interpolating around the peak coarse correlation coefficient. The time of arrival circuit determines a maximum correlation coefficient from the plurality of fine correlation coefficients and a time delay associated with the maximum correlation coefficient, the time of arrival is based on the time delay associated with the maximum correlation coefficient.

Determining the time of arrival of a wireless signal

A split access point is disclosed in which an access point controller is provided for management functions of a plurality of wireless clients on a network and one or more media access controls are provided for moving data packets between the network and the wireless clients. One or more radios are provided for communicating with at least one wireless client. In the present invention, one or more of the access point controller, the media access control(s) and the radio(s) are physically separated so as to provide a split wireless access point.
