The technology involved with the latest breed of phones you can buy at UK mobile phone shops online has made us live most of our dreams to the fullest.

3G or third generation technology is grabbing eyeballs for its fine features and advantages over the 1G and 2G technologies. 1G was introduced in the 1980’s and used radio signals that were analog. It had limited capacity and had security issues which led to the 2G technology. 2G used digital transmission with advantages like increased capacity and security. The battery size became much smaller and enabled increased battery life. 2G can be classified on the basis of multiplexing used. Code division multiple access (CDMA) and time division multiple access (TDMA) are its two variants. The switch to digital networks supported services such as Short Messaging Service and email. The 2G phones can achieve data rates of 144kbps. The main disadvantage of 2G is that the digital networks depend a lot on the proximity of the handset to the cell tower. If a call is made away from a cell tower, it is less likely to catch the signal.

The flaws of 2G gave away to 3G technology. The International Telecommunication Unit (ITU) took initiative and introduced the International Mobile Telecommunication-2000(IMT-2000). IMT-2000 is a group of various terrestrial standards such as TD-SCDMA, CDMA2000 and W-CDMA. These standards are capable of complete network coverage and thus can be called 3G standards.

A smart phone with 3G supports multimedia applications and lets you work even when you are traveling. The mobile phones work like pocket PCs with features like video conferencing, global roaming, high-speed web, TV streaming, instant messaging, online-billing, on-line entertainment, positioning system and virtual banking. With increased bandwidth and data rates, they have the capability to provide minimum speed of 2Mbps and can go as high as 14.4Mbps which is much higher than 2G. 3G networks are more secured than 2Gs. 3G combines your computer, TV and mobile into a single unit and makes communication more efficient and attractive.

3G is definitely more flexible and efficient than its predecessors. But this highly appealing technology does have certain disadvantages. These cellular networks are more costly than the rest and the video conferencing feature can only be enjoyed between the 3G subscribers. If these two factors can be overlooked, then one should not hesitate to buy a mobile phone with 3G technology and explore the wonderful features.
