GSM vs CDMA

"What? Why do you still ask who is the winner of the battle", you may ask. But it is not finished yet, even when the manufacturers are considering which standards would be implemented in their products.
After 2G technology fades away then comes 3G from both standards: GSM launches WCDMA (wide code division multiple access) and CDMA tops its CDMA2000. They still compete each other, even though GSM claimed that WCDMA occupies 48% market in Western market, which is traditionally CDMA's stronghold. But CDMA2000 is being implemented also in some traditional GSM providers like in Indonesia. Sometimes CDMA, CDMA2000, and WCDMA terms in Indonesia can be very confusing. But Indonesia is one example, how these standards are competing a huge market.
3G can not be claimed as the most advanced mobile technology. There is already 3.5G technology, popular as HSDPA (high speed downlink packet access), and even 4G technology has been waiting in the front of your door. The HSDPA has been launched last September in Indonesia, at least by the Excelcom (XL) provider, Indonesian provider owned 60% by Telekom Malaysia. This technology promises up to 2Mbit/s wireless data transfer. It is approximately as much as standard DSL connection in Germany (even though some German providers have offered some cheap high speed DSL - 16 Mbit/s).
Meanwhile Telkomsel, another Indonesian mobile phone operator, has awarded German Siemens to help building its 3G WCDMA infrastructure. Telkomsel has already also some contracts with Nokia and Ericsson made before, but now Siemens is getting this 70 million Euros project. Telkomsel is believed to have around 30 million costumers in Indonesia.
