摘要： A high data rate communication system operating at frequencies greater than 70 MHz and at data rates of about 1.25 Gbps or greater. Preferred embodiments include modulators with a resonant LC circuit including a diode which is back-biased for “off” (i.e., no transmit) and forward biased for “on” (or transmit). The modulator is a part of high performance transceivers for wireless, millimeter wave communications links. A preferred embodiment provides a communication link of more than eight miles which operates within the 71 to 76 GHz portion of the millimeter spectrum and provides data transmission rates of 1.25 Gbps with bit error rates of less than 10−10 . A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of transceivers will be able to simultaneously use the same spectrum. In a preferred embodiment the first and second spectral ranges are 71.8+/−0.63 GHz and 73.8+/−0.63 GHz and the half power beam width is about 0.2 degrees or less. Preferably, a backup transceiver set is provided which would take over the link in the event of very bad weather conditions. In other embodiments especially useful for mobile applications at least one of the transceivers include a GPS locator.

摘要： A lens-based millimeter wave transceiver for use in wireless communication systems operating in the E-band spectrum consistent with the FCC rules regulating the 71-76 GHz and 81-86 GHz bands. The transceiver includes a single lens adapted for transmission of millimeter radiation to form communication beams in one band of either a band of about 71-76 GHz or a band of 81-86 GHz and for collection and focusing of millimeter wave radiation from communication beams in the other of the two bands. It includes a feed horn adapted to broadcast millimeter radiation through said single lens and to collect incoming millimeter wave radiation collected and focused by said single lens. A millimeter wave diplexer separates incoming and outgoing millimeter wave radiation.

摘要： Millimeter wave radio with phase modulation. In preferred embodiments each of the two radios in a link uses a single aperture to transmit radiation in one of the two bands, and receive radiation in the other of the bands. The counterpart radio used to form a link preferably is almost identical, except for the interchange of the transmit and receive frequencies. Preferred embodiments utilize a modulation scheme in which the radios each receive on-off keyed data and transmit the on-off keyed data encoded in a millimeter wave carrier wave with binary phase shift keying.

摘要： A surveillance system utilizing existing street lighting equipment. In a preferred embodiment, surveillance units include a small camera and a wireless transceiver and a connector that allows the surveillance units to plug into an existing outdoor light in the place of the outdoor lights' photo cells. In this preferred embodiment communication between the lights and the cellular station is at frequencies of about 2.4 GHz and uses the 802.11b protocol that permits transmission of data at up to 11 million bits per second or the 802.11g protocol that permits transmission of data at up to 54 million bits per second. The cellular stations then communicates with the central monitoring station at a frequency range of 71-76 GHz and 81 to 86 GHz that permits transmission of data at about 1.0 billion bits per second. In an example system, with 1,000 surveillance cameras (each camera unit plugged into the photocell receptacle of a street light), 100 camera units communicate with each of 10 cellular stations and the 10 cellular stations communicate with a single central monitoring station.
