The 3rd generation of mobile telecommunications technology. Also called Tri-Band 3G.3G network transfers information at least 200 Kbits per seconds, also the later versions ie.3.5G and 3.75G allows information transfer rate at several Mbits per second.

Evolution of 3G from GSM

Universal mobile telecommunication system (UMTS) is an upgrade from Global System for Mobile Communications (GSM) via General Packet Radio Service (GPRS) or Enhanced Data Rates for GSM Evolution (EDGE).

History of 3G:

The first pre commercial 3G network was launched by NTT DOCOMO in japan branded as FOMA. It was first available in May 2001 as a Pre-release (test) of W-CDMA (wideband CDMA) technology.

The first commercial launch of 3g was also by NTT DOCOMO in japan on October 2001, it was delayed by some reliability concerns.

The second commercial launch by SK telecom in South Korea on CDMA in EV –DO technology in January 2002

Adoption of 3g:

3G was relatively slow to be adopted globally. In some instances, 3G networks do not use the same radio frequencies as 2G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates. Other delays were due to the expenses of upgrading transmission hardware, especially for UMTS whose deployment required the replacement of most broadcast towers. Due to these issues and difficulties with deployment, many carriers were not able to or delayed acquisition of these updated capabilities.

Applications of 3G:

The bandwidth and location information available to 3G devices gives rise to applications not previously available to mobile phone users. Some of the applications are:

Mobile TV

Video on demand

Video Conferencing

Telemedicine

Location bases services

Global Positioning System(GPS)

3G is currently the world’s best connection

Higher bandwidth enables a range of new applications!!

For the consumer

Video streaming, TV broadcast

Video calls, video clips – news, music, sports

Enhanced gaming, chat, location services…

For business

High speed teleworking / VPN access

Sales force automation

Video conferencing

Real-time financial information

Evolution of 3g:

 3G systems, however, require far more advanced radio access standards in order to provide Internet access, full-area coverage, and high data rates. The original goal for 3G was to have a single radio access standard for all 3G system. However, in order to allow for the migration from 2G to 3G, three technologies are to be implemented:

~384k-2Mbps, W-CDMA, UWC-136, CDMA 2000

Advantages:

High Bandwidth

High bandwidth, the measure of transmission capacity---is one of the selling points of 3G. This allows you quick and easy access to all of your favourite online multimedia and Internet tools, just like you were at home on a computer. You can pay bills, book dinner reservations, update social networking pages and check e-mails, all on-the-go. While the maximum bandwidth for a stationary 3G device---according to Silicon Press---is 2.05 megabytes (MB), when you are moving slowly (such as walking), this drops to 384 kilobytes (KB). When you and your device are moving at high speeds (such as in a car), the maximum bandwidth drops to 128 KB. However, Silicon Press notes that this is still 10 times faster than the maximum bandwidth of moving 2G devices.

Always-Online Devices

Another advantage of 3G technology is that it can utilise packet-based Internet protocol connectivity. This means your mobile device will always be online and ready for Internet access. However, you will not actually pay for the connection until you start sending or receiving data packets, such as sending an e-mail or looking at a webpage. Some 3G devices are also designed to automatically pick up the closest, free-to-access Wi-Fi signals, in which case, you won't have to pay anything for Internet.

DISADVANTAGES:

Associated Costs

To support 3G technology, updates need to be made to the current cellular infrastructure. According to 3G Internet, this means installing new 3G equipment at---ideally---every current cellular base station and acquiring new frequencies for 3G transmissions. Both of these undertakings are extremely expensive and could take a long time to complete fully. In addition, in order to utilise all of the new features 3G technology has to offer, customers must purchase 3G-compatilible handsets, which are generally more expensive than their 2G counterparts.

Power Requirements

In addition to being more expensive, 3G handsets also require more power than most 2G models. According to Silicon Press, this extra power requirement can translate to larger batteries, shortage usage periods between recharging and more bulky handsets overall.

LIMITATIONS OF 3G/MOTIVATIONS FOR 4G:

3G performance may not be sufficient to meet needs of future high-performance applications like multi-media, full-motion video, wireless teleconferencing. We need a network technology that extends 3G capacity  by an order of magnitude. 

There are multiple standards for 3G making it difficult to roam and interoperate across networks. we need global mobility and service portability

3G is based on primarily a wide-area concept. We need hybrid networks that utilize both wireless LAN (hot spot) concept and cell or base-station wide area network design. 

We need wider bandwidth

Researchers have come up with spectrally more efficient modulation schemes that cannot be retrofitted into 3G infrastructure

We need all digital packet networks that utilize IP in its fullest form with converged voice and data capability.
