It is an exellent method of mental torture. CDMA can be used via predictive text messages on some phones. It can be very confusing however as some words can have MANY different meanings nd can at times make you laugh out loud!
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.
