3G Technology explainedThis is a guest post by Touseef Ahmed of VAC Media (A UK based Online publishing and marketing company).

DEFINITION OF 3G :

3G or 3rd generation is a collection of standards for wireless, mobile communication. The 3G is called International Mobile Telecommunication-2000 (IMT-2000) whose specifications are given by the International Telecommunication Union (ITU). The services are to be such that they satisfy and fulfill the specifications given by the ITU.

HOW IS 3G BETTER :

The 3G is an up-gradation of 2G and 2.5G standards. It includes technologies like UMTS, CDMA2000, WiMAX, etc. Compared to the older 2G technology, the 3G technology has the following enhancements :

·    Higher data speed.
·    Allows simultaneous speech and data services.
·    Provides peak data rates of at least 200 kbit/s.
·    Provides mobile broadband access to smart phone and laptops.
·    Enhanced audio and video streaming.
·    Support for video-conferencing.
·    Browsing at higher speeds.
·    TV through Internet (IPTV) support.

3G FEATURES :

Data Rates :

The data transfer rate for 3G networks is between 128 and 144 kbit/s when the device used is in fast motion and the transfer rate is 384 kbit/s for walking users. For fixed wireless LANs, the rate goes beyond 2 Mbit/s.

Security :

    3G networks offers great security when compared to 2G predecessors. They use the KASUMI block crypto. It provides end-to-end security when application frameworks are accessed.

USING 3G :

The primary thing required for using the 3G technology is a device that is 3G compatible. The device that is 3G compatible is connected to 3G network through its SIM card and therefore its connected to the Internet all over provider’s range which is unlike Wi-Fi for which there is a limited range.

APPLICATIONS OF 3G :   

·    Wide-area wireless voice telephone.
·    Mobile Internet.
·    Video Calls.
·    Mobile TV.
·    Video on demand.
·    Tele-medicine.
·    Location-based services.

FUTURE OF 3G :

3G broadband may be the start of new revolution which is clear by the adoption of it by big parties for its features. But we are in the era of technological boom where one might have just started to get on with the technology and another new one takes birth to create a revolution which is evident from the introduction of 4G technology.

India already started plans for 4G

April 15, 2010 12:52 pm by Jal

India already started plans for 4GWhile the Indian government has managed to rake in 350 billion Rupees ($8 Billion) from the 3G sell-off, the Communications Minister, A. Raja is keen to start early preparations for 4G spectrum. The auction for the 4G spectrum will start immediately after the operators spread out their 3G networks this year.

Mr. A. Raja said,

A. Raja (Communications Minister, India)I do not want any delay in 4G services. We should be with the rest of the world in 4G. The sale process for 4G, which will provide high-speed Internet connections, will begin as soon as operators roll out their 3G networks this year. The Telecom Regulatory Authority of India (TRAI) has already started the pre-consultation process for the sale of 4G spectrum. Once TRAI submits its recommendations, the government will work on it.

Needless to say, 4G will be a grand superset of 3G, up to 10 times faster. 4G is expected to bring in broadband experience to mobile phones enabling smooth streaming of high quality audio and video on mobile devices. Just for your information, Germany has already started Europe’s first 4G auction on 12th April.

India is the world’s fastest growing mobile market and 3G has already turned out to be a massive hit. With 22 rounds of auctions and bids touching 45.8 Billion Rupees (a whopping 31% more than the reserve price fixed by the government), it shouldn’t come as a surprise if government unleashes 4G frequencies next year. India is surely at the threshold of an Internet revolution.
