Cell phones have come a long, long, LONG way since the earliest brick-style handsets that were even larger than a home cordless phone and used only by politicians and tradesmen. That explosion of options in regards to cell phone accessories and technology inclusions means that there is a lot to keep up with! If you’re thinking about buying a new phone, or have recently bought one and are looking to deck it out with cell phone accessories and are feeling overwhelmed at all the foreign-sounding words and acronyms, you need to check out our multi-part cell phone glossary. We aren't working in any particular order (so you won’t need to wait 2 months to find out what a word beginning with 'W' means, for example!).

A/b Switch: These switches allow to move between different carriers on the same telephone, taking advantage of different call rates and specials periods.
Bandwidth: Bandwidth is the capacity of a telephone or telecommunications line to carry signals. Greater bandwidth equals more capacity, which means that more data can be sent in a fixed time period.
Call restriction: This is not really a new technology, but not many people use it to its full extent. Call restrictions can be placed on your cell phone, which mean you might bar all outgoing calls, outgoing international calls, or outgoing multimedia messages.
Clone: Hopefully you never personally find out what this cell phone term means - it refers to using a wireless phone with duplicated stolen electronic identification numbers. People would use clone to make phone calls etc on somebody else's account.
Electromagnetic radiation: There has been much talk about whether cell phones and cell phone accessories emit harmful levels of types of electromagnetic radiation. Currently, even the longest term studies have found no ill effects directly attributable to cell phone use.
General Packet Radio Service (GPRS): This data transmission technique sends and receives data in packets, rather than setting up a constant connection. GPRS can achieve short-term data transfer rates much higher than the standard current GSM network.
