Radio frequency in networking

RF stands for radio frequency network, consisting of wireless electromagnetic signals surpassing an area used by carriers as a mode of communication. RF internet networks use these signals to increase the reliability and access for all the users.

What is RF and how it works?

“RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection. Time-varying voltages and currents generate electromagnetic energy that propagates in the form of waves.

What is RF signal used for?

Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting.
