gsm Technology


Simply, the term GSM refers to the second generation of GSM (2G) voice network that operates based on a mixing of time division multiple access (TDMA) and frequency division multiple access (FDMA). TDMA divides the channel frequencies used into individual bits while FDMA divides the frequency band into several parts and then send one part to each cell phone tower. Cell towers are usually far enough apart so that despite using the same frequency, there will be no overlap in their coverage areas. The term “GSM” is also used to refer to 3G technology implemented by the same telecommunications company and use the same basic network as well.

Information Data Transfer

2G system has a data transmission speed of up to 14.4 kilobits every single second while the 3G system was built in addressing mobile Internet and video needs for transferring faster data. By depending on the interface, the theoretical download speed of 3G network range is about 2 megabits per second (Mbps) to 56 Mbps.

GSM Users

Most countries in the world use the GSM protocol and this protocol is very common in Europe as well as in many developing countries. In contrast to Europe, the United States is more common to use CDMA. In 2002, approximately more than 70% of mobile phone clients all over the world are using GSM services, while about 12% are using CDMA while in early 2010, the GSM Association stated that there were more than 4 billion users, and they estimated the number would increase to 8.3 billion in 2019.
