(sel´ū-l&r) (adj.) Cellular refers to communications systems, especially the Advance Mobile Phone Service (AMPS), that divide a geographic region into sections, called cells.The purpose of this division is to make the most use out of a limited number of transmission frequencies.
Each connection, or conversation, requires its own dedicated frequency, and the total number of available frequencies is about 1,000. To support more than 1,000 simultaneous conversations, cellular systems allocate a set number of frequencies for each cell. Two cells can use the same frequency for different conversations so long as the cells are not adjacent to each other.
