GSM (Global System for Mobile communication) GSM (Global System for Mobile communication) is a digital mobile telephony system that is widely used in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA) and is the most widely used of the three digital wireless telephony technologies (TDMA, GSM, and CDMA).

- GSM Gateways also known as FCTs (Fixed Cellular Terminals or Premicells are used to save money on calls to mobile phone networks. The FCT / GSM gateway connects to a telephone system/PBX and the mobile phone network to allow for calls hugely cheaper than using a normal landline carrier.GSM-FCT-Gateways specialise in the supply and installation of a vast range of Fixed Cellular Terminals (FCT's) from world leading manufacturers.GSM Gateways can also be used in place of a landline.SM-FCT-Gateways specialise in the supply and installation of a vast range of Fixed Cellular Terminals (FCT's) from world leading manufacturers.

CDMA vs. GSM: What's the Difference? CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are shorthand for the two major radio systems used in cell phones. Both acronyms tend to group together a bunch of technologies run by the same entities. In this story, I'll try to explain who uses which technology and what the real differences are.

International Mobile Equipment Identity The IMEI (International Mobile Equipment Identity) is a unique number to identify GSM, WCDMA, and iDEN mobile phones, as well as some satellite phones. The IMEI is only used for identifying the device and has no permanent or semi-permanent relation to the subscriber. Number is used by the GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing the network in that country. The IMEI can be displayed on the screen of the phone by entering *#06# into the keypad on most phones.

- Most US cellular carriers use CDMA. 4G phones generally use LTE (Long Term Evolution), a high speed wireless broadband technology. In most of the world, GSM is preferred and 4G phones with LTE outside of the US use this service.DMA, a competing US standard originally designed by Qualcomm in the United States is used mainly in America and parts of Asia by other carriers. T-Mobile and at&t follow the GSM standard and Verizon and Sprint use the CDMA standard. Nextel uses a third standard developed by Motorola called iDEN.
