We very commonly use the terms 2G or 3G but most of us do not know that the term simply means Second or Third Generation of technology used in the cell or mobile phones. Not many of us know about the 1G standard introduced during the 1980’s, however this was the first step towards the latest heard of 4G technology to be used in the internet, smart phones and tablets.

The existence of cell phones can be easily tracked back to the end of 19th century when the usage of electromagnetic rays was first found for telecommunication purpose, the growth in this field has never looked back ever since. The development however began with the introduction of the first generation cellular technology that used microchips allowing the cell phones to be smaller, sleeker and manageable. The drawback was that these cell phones could transmit only voice calls. This drawback was however taken care of in the second generation technology with the introduction of yet advanced microchips and digitization that helped to not only make voice calls but also send short messages and transmit data.

The 3G (third generation) technology is a general term used for a variety of wireless services together operated through the satellite system and was successfully tested in the year 2001 for the first time. This technology apart from voice calling features higher data transmission speed, faster and bulkier messaging facilities, internet surfing, faxing, voice and video calling, television viewing, roaming facilities and even multimedia entertainment facilities at anyplace you are.

The 3G network is a combination of W-CDMA, 2000-CDMA, UMTS and EDGE that together lead to the latest and finest facilities available in this technology.

W-CDMA (Wideband Code Division Multiple Access) also called the IMT-2000 Direct Spread by the ITU (International Telecommunication Union) is a base for functioning of internet, multimedia, video and other similar applications. This technology uses changeable pace methods in digital processing to attain multi-rate broadcasting.

CDMA-2000 (Code Division Multiple Access) or the IMT Multi-Carrier technology helps send voice and signal data across cell phones.

UMTS (Universal Mobile Telecommunications System) offers greater spectral competence and bandwidth to the mobile network operators that help them cover radio access network and lets customers use the benefits through SIM cards.

EDGE (Enhanced Data Rates for GSM Evolution) technology in the 3G family allows transmission of bulk data at greater speed and other advanced services for newer high-end gadgets.
