Code Division Multiple Access
A spread spectrum approach for the digital transmission of data/voice over radio frequencies. Sound bits are digitized and the data is split into data packets that are encoded with unique identification tags. All of the data/voice is sent over a spread range of radio frequencies. The cell phone or data device receives all of the data packets but only re-assembles those packets with the correct code and transforms the broken-up bits of data into useful sound and data. This allows more traffic for a finite number of available frequencies than analog or the other digital standards.

Automatic Link Establishment (station)
In high-frequency (HF) radio, the capability of a station to make contact, or initiate a circuit, between itself and another specified radio station, without human intervention and usually under emergency conditions. ALE stations are generally computer-controlled.
