3G is an acronym used for referring to third generation in the field of wireless technology and is meant to be an improvement over its predecessors namely 1G and 2G.

So what is 3G exactly and in what way is it better? 3G is the technology which is applied in handsets as well as mobile phones with the intention of facilitating high-speed transmission of data, access to multimedia and roaming facilities all over the world. Some of the common uses of 3G are connection provided to Internet or other IP networks, surfing the web, downloading and uploading the data and making voice and video calls.
While it is true that 3G has many advantages its incorporation and subsequent functionality require conformity with certain pre-requisites. The foremost amongst these is a phone with 3G compatibility followed closely by a SIM card or a 3G data card. In order to acquire 3G connectivity the user needs to subscribe to a service provider of a data or network plan and courtesy of this even though the user is beyond the 3G network he would still enjoy access to 2G or 2.5G.
For the 3G in any device to be effective, the presence of an operating system is a must and one of the most popular choices in this regard is android, in which all applications like email, messaging, browsing, calendar, contact and so on are written in Java programming language. This OS is characterized by many features amongst which are the stimulation of various hardware dependent technologies like Wi-Fi, 3G and Bluetooth.
Another hardware dependent feature of android is the enabling of camera, GPS and accelerometer and this facilitates the presence of two cameras in 3G phones. Therefore, while one camera can be used for video calls the other functions as a user-facing camera and can be used for capturing his image.
Much of the popularity enjoyed by 3G is attributed to its many advantages which render it better than its predecessors in the evolution of technology. Not only is the speed of transferring data higher but there is provision for IPTV support as well.
