1). CDMA is resistant to interference and weather interference, therefore, very low noise CDMA so The sound quality is very good. Even in the pouring rain, which is also the sound quality is still within the limit that can still be tolerated.

2). CDMA can not be duplicated / cloned, because each customer is given different code (unique). This code is very difficult to track because they arerandom.

3). The capacity of CDMA subscribers per BTS can reach 6000 (10 times GSM). This is more economical in the CDMA frequency of use. All BTS CDMA operates on the same frequency, so it does not require The calculation of the complex in configuration. The amount of capacity per BTS make investment costs are very low.

In addition CDMA-2000 (1X) operating in the 800 MHz frequency spectrum. This will make extensive coverage of the BTS far greater than GSM. So that only require less extensive coverage of the BTS for the same if compared with GSM.

4). Power transmitter, which is very low (1 / 100 GSM) allows mobile phones CDMA baterei economical in consumption, so it can operate longer to talk and standby.

5). CDMA-2000 (1X) can send data at speeds of up to 144 Kbps, while GSM 9.6 Kbps. So that services can support SMS, MMS, gaming and down load data via the Internet.
