An analog radio is any radio, whether a transmitter or receiver,
that modulates and demodulates voice communication. The modulation
used is either FM or AM; however, the typical method used in
wireless communication for an analog radio is FM. In an analog
cellular system, the voice communication is digitized within the
cell site itself for transport along the T carrier to the MTSO. The
voice representation and information transfer used in AMPS cellular
is analog, and it is this part in the communication link that
engineers are currently trying to convert to a digital platform. |
