There are two types of wireless transmissions, infrared and radio waves.
Infrared light is similar to visible light because it shares characteristics and is adjacent to visible light on
the light spectrum. However it is a much better medium for transmission of data. There are two required
parts that each infrared system requires. These parts are an emitter and a detector. The emitter sends the
signal, and the detector receives the signal. Directed infrared transmission uses the line of sight principle
which is a direct and narrow beam that the detector picks up through a small "viewing" area. A defused
infrared transmission relies on reflected light. In this sense, the emitter uses a wide focused beam, the
detectors can pick up this signal because the signal produced from the emitter fills the area and reflects
off of certain points which make it possible for the detector to pick up on this signal.
Radio waves are the most common and effective methods of wireless communications today. Radio
waves move outward usually in all directions by traveling through space or air in the atmosphere. Radio
waves can travel for longer distances and penetrate through most solid objects, these waves are also
invisible. When it comes to radio frequency waves over communications devices, there are high
frequency waves, very high frequency waves and ultra high frequency waves. Frequency is measured by
how many waves pass a certain point per second, this measurement is called hertz (Hz). An analog signal
is a continuous wave, whereas a digital signal has separate pulses or breaks in the wave.
