Detailed explanation-1: -The use of detector in wireless communication are as follows :-To detect the audio signals.-To rectify and filter the radio frequency.-To return the good quality audio signal.

Detailed explanation-2: -be able to detect and locate wireless devices at the cell level, meaning with 3 meters or better accuracies; provide unique device identification such that two RF devices can’t be confused during localisation activities, for example providing unique identification: TMSI for Cellular, Mac for WIFI, etc.

Detailed explanation-3: -A detector is an instrument which is used to discover that something is present somewhere, or to measure how much of something there is.

Detailed explanation-4: -The meaning of detection has been extended in the digital communication field from a yes/no decision to a decision at the receiver between a finite set of possible transmitted signals.

Detailed explanation-5: -The purpose of the detector or demodulator circuits is to recover the intelligence impressed on the radio carrier wave at the transmitter. This process is called demodulation and the circuits used to accomplish this are called demodulators. They are also called second detectors in superheterodyne receivers.
