Mobile Communications Terms
With more and more being done on one’s phone—from accessing the Internet to getting directions, calling a loved one, and tracking a vehicle’s location—using mobile devices is not an exception but the norm. Te wireless industry comes with its own tech terms, and understanding them can help one get the most from their mobile connection.
3G – Short for third generation, referring to the third generation of
mobile telecommunications technology. It is based on a set of standards used for mobile devices. Mobile devices use services and networks that comply with the International Mobile Telecommunications-2000 (IMT- 2000) specifications by the International Telecommunication Union. Te 3G technology finds application in wireless voice telephony, mobile Inter- net access, fixed wireless Internet access, video calls and mobile TV.

4G – Te fourth generation of mobile phone technology, following 2G and 3G. Te 2G technology was suitable for making calls and sending text messages, while 3G made it possible to access the Internet more effec- tively through a mobile phone. A 4G system, in addition to the usual voice and other services of the 3G system, provides mobile ultra-broadband Internet access to laptops with USB wireless modems, to smartphones, and to other mobile devices. Even though 4G is a successor technol- ogy of 3G, there can be significant issues upgrading 3G networks to 4G, as many of them were not built on forward compatibility. Conceivable applications include amended mobile Web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, 3D television and cloud computing.
CDMA – Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, in which several transmitters can send information simultaneously over a single communication chan- nel. It allows several users to share a band of frequencies. In order to achieve the connection without interference between the users, CDMA employs spread-spectrum technology and a special coding scheme (in which each transmitter is assigned a code). CDMA is used as the access method in many mobile phone standards, such as cdmaOne, CDMA2000 (the 3G evolution of CDMAOne), and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA.
GSM – Global System for Mobile Communications, originally Groupe Spécial Mobile (GSM), is a standard developed by the European Telecom- munications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by mobile phones. It is the de facto global standard for mobile communications with over 90 percent market share, and it is available in more than 219 countries and territories.
