1) A mobile phone network is made up of group of transmission base stations. Each station (group of antennas) covers only a localized area and is known as a "cell". The cellular network is made up of the group of "cells". Thus when you use a phone that uses this type of network, the phone is known as a cellular phone.
2) A VSWR (Voltage standing-wave ratio) "Sweep Test" is used to measure signal distortion over the medium between the transmitter and the antenna.
Very broad questions but I hope this helps somehow. |
