Explanation: One of the noise difficult to remove is "Flicker noise". This noise is a 1/f power spectral density that occurs in almost all electronic devices, which increases the overall noise level. It also shows up with variety of other effects, such impurities in conductive channels of electronic components.

Error detection and correction in wireless signals work by modulating the carrier signals of a waveform through radio transmission.

Data is not compressed when transmitted, rather data is broken into fragments known as packets and transmitted by method of packet switched networking and applying a protocol called "Transmission control protocol".
