Electromagnetic interference (EMI) is a problem that can affect devices at between the cranes and the antennas is to calculate whether the crane lies in
A radio frequency, or RF, is loosely defined as being in that portion of the electromagnetic spectrum above audio (about 20 kHz) but below infrared (about 30
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to To prevent interference between different users, the generation and
