A method of allocation transmission channels of a frequency band to has each of a plurality of remote stations monitor all channels of the frequency band in its area for the presence of transmissions from stations not part of the network. Each remote station transmits its clear channel list to a master station that aggregates the clear channel list into a reservation map, or map of channels that are clear to all stations in the network. The master station then transmits the reservation map to all stations of the network. The individual stations use the channels of the reservation map to transmit information to the master station. Preferably transmission is accomplished using frequency hopping using a set of channels selected from the reservation map.

Techniques for generating and using a reservation map

A valve malfunctioning detection system for use in a vacuum sewer system including a vacuum pit in fluid communication with a vacuum station is provided. The vacuum pit includes a vacuum sewer valve that is moveable between an opened position and a closed position. The valve malfunctioning detection system may include a radio unit adapted to be carried by the vacuum pit, a gateway radio in communication with the radio unit, a hub radio in communication with the gateway radio to receive a signal transmitted by the gateway radio, and a server in communication with the hub radio. The signal transmitted by the radio unit may include an indication of a status of the vacuum sewer valve.

A bandwidth usage control methodology uses the clear channel detection and frequency agile functionality of a spectral reuse transceiver to effectively 'aggregate' disjoint user channels into an overall bandwidth, the spectral extent of which is at least sufficient to meet a high bandwidth requirement (such as, but not limited to the transmission of data/video), that cannot be realized by a conventional, single channel radio.

Spectral reuse transceiver-based aggregation of disjoint, relatively narrow bandwidth (voice) channel segments of radio spectrum for wideband RF communication applications

A 'smart' sub-channel hopping control mechanism executes one or more sub-channel selection discriminators to enable the communications controller of a spectral reuse transceiver to delineate on which of a plurality sub-channels the spectral reuse transceiver may transmit, so as to substantially reduce the likelihood of triggering squelch circuits of silent radios of primary (licensed) channel users.

Mechanism for avoiding triggering silent radio squelch circuits

A spectral reuse transceiver-based communication system conducts communications between a master site and a plurality of remote sites using a selected portion of a communication bandwidth containing a plurality of sub-bandwidth channels. Each remote site transceiver monitors the communication bandwidth for activity on the sub-bandwidth channels, and informs a master site transceiver which sub-bandwidth communication channels are absent communication activity and therefore constitute clear channels. The master site transceiver compiles an aggregate list of clear channels from all the remote sites and then broadcasts the aggregate list to the remote sites. The master site and a remote site then conduct communications therebetween by frequency-hopping and/or orthogonal frequency multiplexing among the clear channels using an a priori known PN sequence.

A system monitors and detects unauthorized wireless LAN access points and wireless devices. The system includes one or more wireless LAN monitoring devices, which detect and report the presence of unauthorized or 'rogue' wireless LAN access points or wireless devices within a predetermined area, for example, within the vicinity of a wired LAN, including indoor and/or outdoor areas. Improved range is achieved through the use of preamplification and sectorized antennas. Larger areas may be covered using additional wireless LAN monitoring devices, which operate independently or cooperate together in the detection process. Geolocation is possible using single or multiple, cooperating monitoring devices. Provision can be made for monitoring devices to provide packet filtering on a wired LAN.
