microwave repeater
1Repeater — This article is about the electronic device. For other uses, see Repeater (disambiguation). A wireless repeater. A repeater is an electronic device that receives a signal and retransmits it at a higher level and/or higher power, or onto the other …
2Microwave radio relay — is a technology for transmitting digital and analog signals, such as long distance telephone calls and the relay of television programs to transmitters, between two locations on a line of sight radio path. In microwave radio relay, radio waves… …
3Microwave transmission — The atmospheric attenuation of microwaves in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly, such as by oxygen molecules… …
4microwave — A method of radio transmission that uses high frequency waves (in the range of 1 to 30 gigahertz) for line of sight broadband communications. It requires a repeater station every 20 miles or so because of the curvature of the earth. Microwaves …
5Passive repeater — A passive radio link deflection, or passive repeater is a plant for the implementation of a microwave link, in which because of an obstacle in the signal path no direct line of sight microwave link is possible. It has the advantage over the… …
6Radio repeater — A radio repeater is a combination of a radio receiver and a radio transmitter that receives a weak or low level signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. This… …
7Space Lattice Passive Repeater — A Space Lattice Passive Repeater (SLPR) is an advanced type of three dimensional diffraction grating for microwave RF (Radio Frequency) energy. It is used in both commercial and defense wireless applications.The SLPR was developed by American… …
8John D. Goeken — John D. Jack Goeken is a prolific telecommunications entrepreneur. He is the original founder of Microwave Communications Inc., better known as MCI Inc.Founding of MCIAccording to various press reports and the book On the Line by Larry Kahaner,… …
9Saline Valley, California — Saline Valley is a large, deep, and arid valley in the northern Mojave Desert of Southern California. Most of it became a part of Death Valley National Park when the park expanded in 1994. This area had previously been administered by the BLM. It …
10Gravity Probe A — (GP A) was a space based experiment to test Einstein s theory of general relativity performed jointly by the Smithsonian Astrophysical Observatory and the National Aeronautics and Space Administration. It sent a hydrogen MASER, a kind of highly… …
