Wireless networking’s most apparent benefit is its portability. Users of wireless networks may simply join preexisting networks and then move freely between them. A mobile phone user may cover great distances while talking on the phone due to the interconnected network of cell towers. Mobile phone service was quite costly in its early stages. It was only affordable for highly mobile individuals like sales managers and key executive decision-makers who needed to be accessed instantly from wherever. Information in wireless networks may be sent between nodes without the need for a direct wired connection. Radio waves are commonly referred to as “radio carriers” due to their common use in this context. It is possible to precisely retrieve the sent data by superimposing it on the radio signal. The radio signal-occupies more than one frequency once data is superimposed (modulated) onto radio carrier, and this is because the frequency or somehow bit rate of modulating information adds to carrier. When radio waves are broadcast on distinct frequencies, several radio carriers may coexist in the same area without interfering with one another. In order to pick up signals, a radio receiver focuses on a certain frequency while ignoring all others. iv After receiving a modulated signal, it must be demodulated before data can be read from it.
