International Telecommunication Union
1. The International Telecommunication Union, originally founded as the International Telegraph Union, is a specialized agency of the United Nations which is responsible for information and communication technologies. The International Telecommunication Union coordinates the shared global use of the radio spectrum, promotes international cooperation in assigning satellite orbits, works to improve telecommunication infrastructure in the developing world, and assists in the development and coordination of worldwide technical standards.
2. The International Telecommunication Union also organizes worldwide and regional exhibitions and forums, such as ITU TELECOM WORLD, bringing together representatives of government and the telecommunications and ICT industry to exchange ideas, knowledge and technology.
3. The International Telecommunication Union is active in areas including broadband Internet, latest-generation wireless technologies, aeronautical and maritime navigation, radio astronomy, satellite-based meteorology, convergence in fixed-mobile phone, Internet access, data, voice, TV broadcasting, and next-generation networks.
4. The International Telecommunication Union is based in Geneva, Switzerland, is a member of the United Nations Development Group and its membership includes 193 Member States and around 700 Sector Members and Associates.

Microwaves
1. Microwaves are a form of radiant energy. Other common forms are radio waves, visible light, infrared heat and electricity. All forms of radiant energy are a part of the electromagnetic spectrum. To distinguish between the forms, they are classified according to the wave length which may vary from miles to thousandths of an inch.
2. Microwaves are located in the non-ionizing portion of the energy spectrum between radio waves and visible light. The first application of microwaves was in radar during World War II. Today microwaves are widely used in communication systems, radar and many other commercial and industrial applications.
3. Significantly large segments of the population are exposed to infrared rays, visible light waves and microwaves every day. One characteristic of microwaves is their ability to bounce or deflect off metal surfaces, a characteristic basic to its use in radar. Another is its thermal or heating effect utilized in microwave cooking.
4. The difference between microwave energy and other forms of ionizing radiation, such as X-rays, Alpha, Beta and Gamma rays, is that microwave energy is non-ionizing. In other words, it does not alter the molecular structure of the item being heated. The effects of microwave energy are strictly thermal and do not cause cellular change as with ionizing radiation.

Radar applications
1. The information provided by radar includes the bearing and range (and therefore position) of the object from the radar scanner. It is thus used in many different fields where the need for such positioning is crucial. The first use of radar was for military purposes: to locate air, ground and sea targets. This evolved in the civilian field into applications for aircraft, ships, and roads.
2. In aviation, aircraft are equipped with radar devices that warn of obstacles in or approaching their path and give accurate altitude readings. The first commercial device fitted to aircraft was a 1938 Bell Lab unit on some United Air Lines aircraft. Such aircraft can land in fog at airports equipped with radar-assisted ground-controlled approach systems in which the plane's flight is observed on radar screens while operators radio landing directions to the pilot.
3. Marine radars are used to measure the bearing and distance of ships to prevent collision with other ships, to navigate, and to fix their position at sea when within range of shore or other fixed references such as islands, buoys, and lightships. In port or in harbour, vessel traffic service radar systems are used to monitor and regulate ship movements in busy waters. Police forces use radar guns to monitor vehicle speeds on the roads.
4. Meteorologists use radar to monitor precipitation. It has become the primary tool for short-term weather forecasting and watching for severe weather such as thunderstorms, tornadoes, winter storms, precipitation types, etc. Geologists use specialized ground-penetrating radars to map the composition of Earth's crust.

Transmitter
1. In electronics and telecommunications a transmitter or radio transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. In addition to their use in broadcasting, transmitters are necessary component parts of many electronic devices that communicate by radio, such as cell phones, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, and spacecraft, radar sets, and navigational beacons.
2. The term transmitter is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters even though they often have similar circuits.
3. The term is popularly used more specifically to refer to a broadcast transmitter, a transmitter used in broadcasting, as in FM radio transmitter or television transmitter. This usage usually includes both the transmitter proper, the antenna, and often the building it is housed in.
4. An unrelated use of the term is in industrial process control, where a "transmitter" is a telemetry device which converts measurements from a sensor into a signal, and sends it, usually via wires, to be received by some display or control device located a distance away.
