Mobile Phone Technologies

Are you one of the many people who purchase mobile phones without really understanding what the vague acronyms in the specs mean? If you answered yes, then, read on to find out what GSM, CMDA, 3G and the like actually stand for and how these things contribute to the workings of your mobile phone.

What Are They?

Mobile phone technologies are what you call the acronyms like GSM, CDMA, TDMA and 3G. These are mechanics used by network operators to enable phone users to communicate with other subscribers. These technologies vary from each other by means of how they connect subscribers to each other, by how much and what kind of data they transmit, and by the length of time data is transmitted.

How Do They Work?

The first of mobile phone technologies is the 1G or first generation method which uses radio frequencies. Every call needs a unique frequency so communication disturbances may be limited. When this method limited user count, the 2G technology was designed.

2G uses digital networks and enables several subscribers to connect using one frequency. This method was made possible by fractioning a radio frequency to several users, each user holding a specific alloted time in each frequency.

Further development of mobile phone technologies involved transmission of more types of data and decreasing transmission time. These became more helpful to mobile phone users so the demand for the latest mobile phone technology increased.

What Types of Mobile Phone Technologies Are There?

FDMA or frequency division multiple access is a 1G technology while TMDA or time division multiple access is 2G.

CDMA or code division multiple access may be classified under 2G and also 3G.

GSM or global system for mobile communications is another example and it offers clearer communication and safer service.

More On CDMA, GSM and 3G

• CDMA - This was first popularised by a company called Qualcomm in mid 1990's. It is an improvement after the TDMA technology. It was highly demanded in the mobile phone market.
• GSM - This may be updated to UMTS (Universal Mobile Telecommunications Standard) via GPRS (General Packet Radio Service).
• 3G - This is the highest, most popular technology to date but is created with a system that enables current development to 4G.
