What is 3G?

3G in video 

A radio communications technology that will create a "bit pipe" for providing mobile access to internet-based services. It will enhance and extend mobility in many areas of our lives.

3G Wireless (Definition)

3G stands for the third generation of wireless communication technology. It refers to pending improvements in wireless data and voice communications through any of a variety of proposed standards. The immediate goal is to raise transmission speeds from 9.5K to 2M bit/sec. 

In the near future, mobility won't be an add-on: it will become a fundamental aspect of many services. We'll expect high-speed access to the internet, entertainment, information and electronic commerce (e-commerce) services wherever we are - not just at our desktop computers, home PCs or television sets. 3G services will add an invaluable mobile dimension to services that are already becoming an integral part of modern business life: Internet and Intranet access, video-conferencing, and interactive application sharing. 2G Wireless The technology of most current digital mobile phones Features includes: - Phone calls - Voice mail - Receive simple email messages Speed: 10kb/sec Time to download a 3min MP3 song: 31-41 min 2.5G Wireless The best technology now widely available Features includes: - Phone calls/fax - Voice mail -Send/receive large email messages - Web browsings - Navigation/maps - New updates Speed: 64-144kb/sec Time to download a 3min MP3 song: 6-9min 3G Wireless Combines a mobile phone, laptop PC and TV Features includes: - Phone calls/fax - Global roaming - Send/receive large email messages - High-speed Web Navigation/maps Videoconferencing - TV streaming - Electronic agenda meeting reminder. Speed: 144kb/sec-2mb/sec Time to download a 3min MP3 song: 11sec-1.5min We are not just talking about "road warriors" who spend their entire lives travelling. It's more a question of supporting new, flexible working practices where employees need access to a wide range of information and services via their corporate intranets, whether they are at their own desk or anywhere else. Employees who spend some of their working at home. Accountants that carry out audits at client premises. On-site maintenance engineers who need access to detailed instruction manuals, mobile emergency services who need a video link with a hospital or doctor for specialised advice. These are a few situations where 3G will play a valuable role. Key features of 3G systems are a high degree of commonality of design worldwide, compatibility of services, use of small pocket terminals with worldwide roaming capability, Internet and other multimedia applications, and a wide range of services and terminals. 3G System Capabilities Capability to support circuit and packet data at high bit rates: • 144 kilobits/second or higher in high mobility (vehicular) traffic • 384 kilobits/second for pedestrian traffic • 2 Megabits/second or higher for indoor traffic Interoperability and roaming Common billing/user profiles: • Sharing of usage/rate information between service providers • Standardized call detail recording • Standardized user profiles Capability to determine geographic position of mobiles and report it to both the network and the mobile terminal Support of multimedia services/capabilities: • Fixed and variable rate bit traffic Bandwidth on demand • Asymmetric data rates in the forward and reverse links • Multimedia mail store and forward • Broadband access up to 2 Megabits/second We're likely to see 3G services enter our day -to-day lives in all sorts of new ways: for example, in shopping, especially Internet "mail order" (e-commerce), banking, or playing interactive computer games over the Net. We'll think nothing of sitting on a train and using a mobile palmtop with Internet browser to log into our bank accounts. While on-line we'll be able to check our accounts, pay a few bills and click on a screen icon to immediately set up a video-conference to discuss our account with a bank clerk. On vacation, we'll be able to use our mobile palmtops to obtain local tour guides, make a last-minute reservation at a hotel, find and call the nearest taxi firm, and send video postcards. We'll expect location-independent mobile access to a personalised set of services that matches the way we live and work. Increasingly, machine-to-machine communications will also be enabled and enhanced with future mobile network technology. Domestic appliances will have built-in radio modems to provide remote control and diagnostics. Our refrigerators will have built-in sensors that detect which items need restocking and automatically send a reminder message to our Personal Digital Assistants (PDAs). We could even get the refrigerator to send an order direct to our local store. Likewise, vending machines will be able to tell the warehouse when they need restocking.
