Everybody is aware of the fact that the technology keeps on evolving from one form to the other everyday & for all the stuff related to it. This pattern of changing & improving mobile technology makes it very complicated for the people to use the mobiles with the latest technology. The terms like 3G, GSM, TDMA, CDMA, FDMA, GPRS, WAP, EDGE, etc. are not so understandable as far as the common people are concerned, who cannot digest such terminologies of the changing mobile technology.
Generations of Mobile Communication
The terms 3G, has evolved from the other terms like 1G, 2G, etc. where they indicate the generation of the mobile communication. For example, 1G is the short form of 1st Generation, and so on. This 1G mobile was introduced or launched in 1970s, which was primarily used for only voice transfers. The 2G-2nd Generation mobiles came into existence in 1990s, which was further developed to 2.5G including GSM, TDMA & CDMA. These mobiles were used for transferring voice & data.
The present generation of mobiles is 3G, which delivers the data speed from 384kbps to 2mbps over the wireless interfaces like GSM, TDMA & CDMA.
FDMA: Frequency Division Multiple Access
FDMA uses separate frequencies for each call and they do not interfere amongst themselves, which limits the number of users because of this reason.
TDMA: Time Division Multiple Access
TDMA allocates unique time slots to each user within each channel, enabling many users to access the radio frequency without anybody else’s invitation. Each mobile conversation uses only a particular frequency slot of the time.
CDMA: Code Division Multiple Access
This was commercially used in 1995 by Qualcomm & had become very quickly & fastest growing wireless mobile technology. The 3G CDMA network provides more clarified voice traffic with the high-speed data capabilities. This technology enables a very wide usage of the features of a mobile phone & also it is one of the cost-saving technology where the people can get many benefits with the lowest possible costs.
GSM: Global System for Mobile
GSM was developed by TDMA protocol in Europe, which has become a standard mobile technology for mobiles across the globe. It provides a very high level of security & a superior sound quality. This technology is globally accepted, which needs a SIM card (Subscriber Identity Module) that contains the telephone service account information subscribed by you. These SIM cards are different based on the location of the person. The card of one location cannot be used on other location, unless & until your service provider approves for it.
GPRS: General Pocket Radio Services
GPRS is an enhancement to the GSM mobile technology that offers the high-speed connectivity to the internet. With this facility, you can check the emails, download games, transfer the messages to the computer, etc. which can be browsed at a very high-speed.
WAP: Wireless Application Protocol
WAP is the portable internet access facilitating technology through the mobiles. If anyone wants to use the internet over the mobile, or wants to see the web content on mobile, it is necessary to have the WAP enabled mobile & the WAP service enabled by the service provider. This mobile technology, like GPRS, enables the downloads of the games, send email, transfer the messages to the computer, etc.
EDGE: Enhanced Data GSM Environment
This mobile technology has specifically been designed to meet the bandwidth needs of 3G. EDGE was introduced by Ericsson & it offers high-speed data transfers over the GSM networks with just a software upgrade to the handset. This technology allows the speed up to 384kbps.
The journey of the mobile technology development with all these evolutions has facilitated the people to such a higher extent, that the future of these technologies is seen to be very bright. The technology will never stop evolving & so will the people’s ideas, ensuring better ways of using the mobile phones.
