Radio Frequency communication is very popular in the electronics world. It also enables the wireless networks that can securely maintain the broadcast information. RF communication has the wide span of a frequency spectrum, i.e.. it can go beyond the range of reach of wired communication. The amplitude of the radio frequency signal is lower than the background noise amplitude, which increases the efficiency of signal transmission. Besides, the strength of the signal is maintained throughout the distance between transmitter and receiver. The RF communication can use the bandwidth from 9 kHz to several GHz frequencies, which is quite compatible for transmissions of data as well as voice signals. Radio frequency devices and transmitter band width ranges must be checked and authorized by the Federal Communication Commission, based on the type of service of the RF device. Low frequency radiation is not suitable for wireless communication because the distortion of the ...
