Wireless technology implementation in Indonesia

The development of telecommunications technology very quickly, especially in the field of wireless or mobile. Currently in Indonesia, almost all operators offering 3G services.

If we see the history of the development of wireless services are as follows:

First generation (1G) - the service that is provided only voice (vote), the technology used is based AMPS Frequency Division Multiple Access (FDMA), is still analog. Operator in Indonesia at that time the technology is Metrosel, Telesera.

Second generation (2G) - different from the preceding generation, this generation has been based on digital technology, which is carried GSM and CDMA IS-95A. GSM use Time Division Multiple Access (TDMA), and CDMA use Code Division Multiple Access. Operator in Indonesia that use GSM technology: Telkomsel, Excelcommindo, IM3, Mentari, Tree (3) and the Axis. And CDMA is used by Flexi, Esia, Fren, Hepi, StarOne, and Sampoerna Telecommunication Smart. 2G services, other than the voice can also sms and data circuit. Between 2G to 3G technology is the 2.5 generation CDMA IS-95B-GPRS and EDGE. But technology is less in the booming market.

Third generation (3G) - There are two major stronghold of play in the 3G technology. Stronghold of the European-based GSM and stronghold of the original CDMA-based. The GSM player use WCDMA, and CDMA palyers use CDMA2000 EV-DO. In Indonesia, almost all the major players, namely GSM Telkomsel, Indosat and Excelcomindo dive to WCDMA. While CDMA2000 is used by Fren. With 3G services access data more quickly, so that it can play video. No lapse of the lam, 3.5 G technology appears to use HSPA technology, this technology uses OFDM access. Telkomsel and Indosat are using this technology.

Fourth generation (4G) - This is our waiting-waiting in attendance. There are 2 technology, which carried the WiMAX and LTE

Well, shortly GSM technology will be abandoned, as well as with AMPS technology first. GSM goodbye.
