What is Amp?
AMPS is an abbreviation for advanced mobile phone system.AMPS allocates frequency ranges within the 800 and 900 Megahertz (MHz) spectrum to cellular telephone. Each service provider can use half of the 824-849 MHz range for receiving signals from cellular phones and half the 869-894 MHz range for transmitting to cellular phones. The bands are divided into 30 kHz sub-bands, called channels. The receiving channels are called reverse channels and the sending channels are called forward channels. The division of the spectrum into sub-band channels is achieved by using frequency division multiple access (FDMA). The signals received from a transmitter cover an area called a cell. As a user moves out of the cell`s area into an adjacent cell, the user begins to pick up the new cell`s signals without any noticeable transition. The signals in the adjacent cell are sent and received on different channels than the previous cell`s signals to so that the signals don`t interfere with each other.
