What is 3G Technology?
3G is the next generation of technology which has revolutionized the telecommunication industry. Apart from increasing the speed of communication, the objective of this technology is to provide various value added services like  video calling, live streaming, mobile internet access, IPTV, etc on the mobile phones. These services are possible because the 3G spectrum provides the necessary bandwidth.

The term 3G refers to the third generation of mobile phone standards, as set by the International Telecommunications Union (ITU). 3G technologies allow mobile operators to offer more service options to their users, including mobile broadband.

3G offers greater flexibility and services by making more efficient use of mobile bandwidth than its predecessor 2G. And although faster, newer 4G technology is now available in the UK, 3G remains the UK's dominant mobile broadband technology.

The relationship between 2G and 3G is similar to that of dial-up and broadband, or terrestrial TV and digital TV. In all of the latter examples, greater spectral efficiency has enabled more consumer choice and a more effective service. Simply put, more data can be transmitted faster.

Technically speaking 3G is a network protocol which refers to the generations of mobile phones and telecommunication equipments which are compatible with the International Mobile Telecommunications-2000 (IMT-2000) standards stated by International Telecommunication Union (ITU). The basic requirement for compiling to IMT-2000 standards is that the technology should provide peak data rates of atleast 200 kbit/s. It’s worth mentioning that speed isn’t the only criteria for deciding whether the network protocol is 3G or not. 3G isn’t just any high speed network but a protocol which has its own standards defined under IMT-2000 by ITU.
3G Technology is designed for multimedia communication. It provides services like higher data transfer rates. One of its key visions is to provide seamless global roaming, enabling users to move across borders while using the same number and handset. According to ITU it is expected that IMT-2000 will provide higher transmission rates: a minimum speed of 2Mbit/s for stationary or walking users, and 348kbit/s in a moving vehicle.

3G and mobile broadband

3G enables devices such as mobile phones and mobile dongles to deliver broadband-speed internet. Even the lowest-end, cheapest mobile phones are now 3G enabled, making it easy to check emails and browse the web on the go.

Mobile broadband via dongles and smartphones has taken off extremely fast. Mobile broadband allows customers to browse the internet, check email and download files, music and video clips from their laptops and PCs wherever there is coverage.

3G is made possible by two complementary technologies - HSDPA and HSUPA (high speed download and upload packet access, respectively). These technologies enable mobile broadband users to access download speeds of up to 21Mb and upload speeds of up to 1.76Mb via a mobile dongle, USB modem or MiFi.

Predecessors of 3G such as 2G and GPRS offered limited internet connectivity that was often costly and slow. Conversely, because 3G uses the airwaves more efficiently, it can offer greater speeds with prices starting at less than £5 per month on some of the cheapest one-month, rolling contract deals.
