Why mobile phones sometimes become a challenge today? This is largely due to the existence of different incompatible systems throughout the mobile world, which can make the entire region of the other. That is, the technology in which a mobile network works totally different from others.

Say, for too deeply into the technical aspects of each system, GSM, TDMA, CDMA, NMT, D-AMPS, etc. are systems that use mobile phones work and in most cases, a mobile telephone system is not compatible with others. So what are all the systems and how to coexist in the mobile world?

Global System for Mobile Phones (GSM)

GSM is one of the few mobile phone systems widely adopted worldwide. System GSM mobile phones are used in almost 200 countries, from Europe to the world.

Technically, he said, the system uses the 900 MHz spectrum for its signal to travel through the air. GSM providers in Europe, Africa and Asia later added additional spectrum in 1800 Mhz. However, in North America, the service GSM operates at 800 MHz or 1900 MHz

The good news here for world travelers is that most manufacturers offer dual-band (900 and 1900 MHz), Tri-band (900, 1800 and 1900 MHz) and quad-band (800, 900, 1800 and 1900 MHz), mobile phones these phones can be used almost anywhere instead of GSM systems are installed. However, countries like South Korea and Japan do not use the GSM system for mobile telephony services. A mobile phone with tri-band should be one that world travelers should have to be available for international roaming agreements of various GSM operators worldwide.

To add, this system offers excellent coverage, and even in some cities, is used in moving subway train after modifying some mobile devices. GSM is an innovative system that lets you send faxes and SMS (Short Messaging Service). So you can receive flight updates and news alerts on your phone mobile instant.

Time Division Multiple Access (TDMA)

TDMA is the first widely used digital wireless network in the U.S.. The system continues representing the core of the major U.S. networks wireless network providers and only in recent days are converting some of their widths GSM 1900 band. Very few regions in the world other than the U.S. use this system. However, estimates of future shows that the increasing growth of GSM and CDMA in the U.S. cease TDMA system.

Code Division Multiple Access (CDMA)

Developed by Qualcomm, is the competitor of TDMA in the U.S.. There are currently installed array CDMA systems adopted elsewhere in the world. This system offers international roaming capability similar to that of GSM. One of the most important side CDMA is more efficient than GSM in some respects. But in practice, GSM has been widely used and have rich features than CDMA.

Without But few other systems exist elsewhere in the world, but are technically obsolete. Out of many GSM and CDMA systems are those that have been established and egressing more.
