What Is 2G Technology?

2G is short for second-generation wireless telephone technology. The prime aim of this article is to answer what is 2g technology and give our visitors a true explanation of 2g technology. Read on to know more.

2g technologies are based on what type of multiplexing is employed, for instance, the procedure of merging multiple digital data streams into one signal. Classified by whether they are based on time division multiple access (TDMA) or code division multiple access (CDMA), the 2G standards may include the following: Integrated Digital Enhanced Network (IDEN) or Global System for Mobile communications (GSM), used worldwide. Digital Advanced Mobile Phone System (D-AMPS) is used in North and South America, while Personal Digital Cellular (PDC) is used in Japan.

2G telecom networks were commercially launched in 1991 on the GSM standard in Finland. The 2G systems were found to be considerably more efficient on the spectrum, allowing far greater mobile phone penetration levels. Moreover, the phone conversations were digitally encrypted.

Getting on with the meaning of 2g technology, 2G makes use of a CODEC or compression-decompression algorithm for compressing and to multiplex digital voice data. Using this technology, it is possible for a 2G network to bundle more calls per amount of bandwidth. As the data is transmitted through digital signals, 2G also offers extra services such as SMS and e-mail. Moreover the battery lasts longer due to the lower-powered radio signals. Digital voice encoding, offering a feature of error checking, also improves the sound quality by reducing dynamic and lowering the noise floor.

Although 2g technologies have much more benefits to offer over its predecessors, it has a few disadvantages as well. The 2G's digital signals are very dependent on location and proximity. A call made from far away may not allow the digital signal to be strong enough to reach it. Moreover, the digital signals used in 2g technologies have a jagged, angular curve, which can fail completely under unsuitable conditions.

We are sure the 2g technology explained in the above article would have given you a broader insight on the topic.
