articles and information on cellular telecommunication / cell phone technology
There are many mobile or cell phone systems that are in use all over the world and there is a considerable amount of equipment ranging from the cell phones themselves to cellular base stations, antennas and the network infrastructure.
In addition to the basic equipment there is new cell phone technology to provide the many new services that are now available, enabling cell phone users to enjoy many new applications from games, and ringtone downloads to picture and video downloads. With technologies ranging from GSM, GPRS, EDGE to UMTS or W-CDMA and cdmaOne (IS-95) to CDMA2000 1X, EV-DO and EV-DV and mobile TV technologies such as MediaFLO, DMB, and DVB-H, there are plenty of technologies in use.
There is plenty of terminology associated with cellular telecommunications and cell phone technology. Our terminology glossary explains the most commonly used terms associated with cellular telecommunications / cell phone technology:
The technology behind cellular systems and cell phones has developed from the first generation (1G) systems to the second geenration (2G) systems and then to the third generation (3G) systems. At each stage the performance improved and further facilities were available, from SMS messaging to video downloads.
- Major Mobile Phone Systems (a tabular overview)
- The Route from Analogue to 3G
Cellular telecommunications basics.
There are a number of basic concepts behind cellular telecommunications systems. These include the idea of cells themselves as well as how the networks are set up, what is in a mobile phone and how some of the transmission technologies such as CDMA, TDMA and the like operate.
- The basic concept of a cellular telecommunications system
- The multiple access schemes used by mobile phones
- The duplex schemes used by mobile phone networks - FDD and TDD
- The operation and electronics within a mobile phone
- The basics of a cellular network
- The way in which a mobile phone registers onto a network
- Handover or handoff, the way in which cellular calls are transferred from one cell to another
- Code Division Multiple Access (CDMA) What it is and how it works
