WIRELESS

Wireless operations permits services, such as long range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls, computer networks, network terminals, etc.) which use some form of energy

TYPES OF WIRELESS TECHNOLOGY:-

• 
  
  INFRARED
• 
  
  BLUE TOOTH
• 
  
  RADIO
• 
  
  MICROWAVE
• 
  
  SATELLITES

INFRARED is a wireless transmission medium that carries data via beams of light through the air. No wires are required, but the transmitting and receiving devices must be in line of sight or the signal is lost.

BLUE TOOTH is a short range radio transmission technology that has become very popular in recent years. Bluetooth enable devices identify each other using identification numbers that are unique to each device. When these devices are within 30 feet of each other, they automatically find and link to one another

MICROWAVES are high frequency, electromagnet radio waves with very short frequencies that are used to transmit data. Using relay stations similar to satellite dishes, microwave signals are sent from one relay station to the next because microwave must travel in a straight line with no obstructions

SATELLITES are positioned in geosynchronous orbit which matches the speed of the Earth rotation and therefore are permanently positioned with respect to the ground. Satellites transmit data by sending and receiving microwave signals to and from Earth based stations
