CDMA, an abbreviation for Code Division Multiple Access is a digital cellular technology using frequency spectrum, which is much more efficient in comparison to a dedicated land-line. TDMA, an abbreviation for Time Division Multiple Access is a technology which delivers digital wireless service and uses the time division multiplexing channel. In this way, a single frequency or spectrum can handle several data channels.
Often people are curious to know as to which is more efficient – TDMA or CDMA. However, it is quite hard to specifically classify the superiority, considering both have their own pros and cons. For those, who are confused, TDMA is nothing but the same technology which existed in the GSM cellular technology till now.
In a perfect environment, a CDMA phone would provide sufficient service with a receiving signal level of -105 dBm, while TDMA would require -99 dBm. A 7 dBm advantage for CDMA still might not justify the superiority.
