High Quality Content by WIKIPEDIA articles! A Radio Atmospheric signal or Sferic (sometimes also spelled "Spheric") is a broadband electromagnetic impulse that occurs as a result of natural atmospheric lightning discharges. Sferics may propagate from their lightning source without major attenuation in the Earth-Ionosphere waveguide, and can be received thousands of kilometers from their source. On a time-domain plot, a sferic may appear as a single high-amplitude spike in the time-domain data. On a spectrogram, a sferic appears as a vertical stripe (reflecting its broadband and impulsive nature) that may extend from a few kHz to several tens of kHz, depending on atmospheric conditions. Sferics received from about two thousand kilometres...

High Quality Content by WIKIPEDIA articles! The radioisotope rocket is a type of rocket engine that uses the heat generated by the decay of radioactive elements to heat a working fluid, which is then exhausted through a rocket nozzle to produce thrust. They are similar in nature to the nuclear thermal rockets such as NERVA, but are considerably simpler and often have no moving parts. The basic idea is a development of existing radioisotope thermoelectric generator, or RTG, systems, in which the heat generated by decaying nuclear fuel is used to generate power. In the rocket application the generator is removed, and the working fluid is instead used to produce thrust directly. Temperatures of about 1500 to 2000°C are possible in this...

High Quality Content by WIKIPEDIA articles! A radio access network (RAN) is part of a mobile Telecommunication system. It implements a radio access technology. Conceptually, it sits between the Mobile phone, and the core network (CN). The mobile phone is varyingly known as user equipment (UE), terminal equipment, mobile station (MS), etc., depending on the standard. The term RAN is typically used in regards to the GSM, UMTS, and associated family of standards. While there is no direct equivalent in TIA standards such as IS-136 and IS-95, the equivalent would be the air interface of that network, coupled with those components governing the networking of base stations and their connection to the core network.

High Quality Content by WIKIPEDIA articles! In British English, a radiogram is a now old-fashioned piece of furniture that combined a valve radio and record player. The word radiogram is formed by a combination of the words radio and gramophone. Radiograms reached their peak of popularity in the late 1950's, supported by a rapidly growing interest in records. Originally they were styled in polished wood to blend with the furniture styles of the 1940s and 1950s. Later models took on the modern lines and plastic finish of the 1960s. When valve radio development ended in the early 1960's and transistors began to take over radiograms became obsolete. By the early 1970s, they had been replaced by more compact equipment, such as the Hi-Fi and...

A radio-controlled aircraft (often called RC aircraft or RC plane) is a model aircraft that is controlled remotely, typically with a hand-held transmitter and a receiver within the craft. The receiver controls the corresponding servos that move the control surfaces based on the position of joysticks on the transmitter, which in turn affect the orientation of the plane. Flying RC aircraft as a hobby has been growing worldwide with the advent of more efficient motors (both electric and miniature internal combustion or jet engines), lighter and more powerful batteries and less expensive radio systems.

High Quality Content by WIKIPEDIA articles! Radiolocating is the process of finding the location of something through the use of radio waves. It generally refers to passive uses, particularly radar — as well as detecting buried cables, water mains, and other public utilities. It is similar to radionavigation, but radiolocation usually refers to passively finding a distant object rather than actively one's own position. Both are types of radiodetermination. Radiolocation is also used in Real Time Locating Systems (RTLS) for tracking valuable assets. An object can be located by measuring the characteristics of received radio waves. The radio waves may be transmitted by the object to be located, or they may be backscattered waves (as in...
