TDMA vs CDMA
In the United States, there are a number of different standards and technologies for wireless phones. This combination of standards and technologies can become very confusing for you. This training guide will give you a brief overview of the different technologies which will help you understand the differences.
TDMA, (Time Division Multiple Access)
is a digital technology that allows multiple users to share the same voice channel by having each conversation transmitted alternately over short lengths of time.
CDMA, (Code Division Multiple Access)
is a digital technology that separates communications by code. This way, the system can mix a number of calls into the same channel. When the tower receives the information, it looks at the coding and reassembles each individual call, completing the transmission.
GSM, (Global System for Mobil communication)
is the name of a TDMA type of Digital system originally developed in Europe, and common throughout Asia. This system is being used by some of the PCS operators in the USA.
