Various Types of Cellular Technology

Along the development of technology especially in the field of mobile technology (mobile phone), here Amws want to try to explain some of the technologies that already exist today. Technology, among others:

1. AMPS

AMPS perhaps the first technology used in mobile technology. AMPS or Advanced Mobile Phone Service is the analog cellular system that was first used in the United States and eventually diaman widely used until 1997 of 72 countries has used this system for cellular technology. This technology is prone to do reproductive cloning because of the lack of protection wiretapping.

2. D-AMPS

AMPSDigital D-AMPS or often referred to as TDMA technology (Time Division Multiple Access) is a 2nd-generation technology (2G) of AMPS, which in this technology allows for multiple users in a same frequency whereas this is not possible on technology AMPS. This technology is equivalent to GSM technology.

3. CDMA

CDMACDMA or short for Code Division Multiple Access is a 3rd generation technology (3G) of mobile phone technology. CDMA is a military technology first used during World War II by English allies to foil German business interfere with their transmission. Allies decided to transmit not only on one frequency, but at some frequencies, making it hard to catch the Germans complete signal. Since the birth of CDMA has many technologies that use this system one of them on GPS technology

4. CDMA2000-1x

CDMA2000-1x is the development of CDMA technology in terms of data transfer. 1x means 1xRTT (Single-Carrier Radio Transmission Technology) or 1-channel data transfer frequency of 1.25MHz data. CDMA2000-1x is often also called Multi-Carrier IMT is a family of third generation (3G)

5. EV-DO

Modem-DOEV EV-DO technology is a continuation of the CDMA2000-1x. EV-DO or Evolution-Data Optimized often called Evolution-Data Only. As the term is EV-DO high speed data interfaces that are part of the 3G technology. Technically, this technology is capable memtransfer data up to 2.4 megabits per second. EV-DO technology of data transfer speed is divided into EV-DO Rev 0 (called EV-DO) capable of transferring data up to 2.4 megabits per second, EV-DO Rev A capable of transferring data up to 3.1 meabits per second and EV-D

 


6. GSM

GSM (Global System for Mobile Communications) is a standard commonly used in cellular technology. GSM is a standard for digital mobile communications that are introduced in the mid-1991 and used as a mobile technology standard used throughout Europe. GSM is a 2nd-generation technology (2G)

7. GPRS

General Packet Radio Service is a technology that allows sending and receiving data faster than the use of technology Circuit Switch Data, or CSD. GPRS is part of a more mefokuskan GSM technology in data transfer. GPRS is part of the 5.2 generation (2.5 G)

8. EDGE

EDGE technology is a technological evolution from GSM / GPRS network. Stands for EDGE or Enhanced Data rates for GSM developed to improve data transmission. When on GPRS technology only offers data transfer speeds of 115 kbps, the EDGE is theoretically capable of providing data speeds up to 473.6 kbps or three klai folding of GPRS technology.

9. HSDPA

As the handle links by the development of 3G technology begins HSDPA (High Speed Downlink Packet Access) technology that is generations 3.5, where the technology is made possible data transfer up to 3.6 Mbps.

10. Long Term Evolution (LTE)/4G

WiMaXSaat may 4G is the latest generation of cellular technology. In theory this technology is capable of reaching speeds up to 1Gb/detik 100Mb/detik. Each handset 4G will immediately have the number of IP v6 is equipped with the ability to interact internet telephony-based Session Initiation Protocol (SIP). One application of 4G is WiMAX (Worldwide Interoperability for Microwave Access)
