“Other mobile phone operators are not permitted to upgrade to 3G until Third Operator has been in operation for two years,” Lotfollah Sabouhi told Mobna news agency.
۳G is a new generation of mobile phone network with multimedia capabilities. It is in contrast to GSM technology which transfers voice and information. 3G facilitates high-speed multimedia transfer.
The International Telecommunication Union (ITU) has set third generation technology (3G) of mobile telephony standards – IMT-2000 – to facilitate growth, increased bandwidth, and support of more diverse applications. For example, GSM (currently most popular cellular phone standard) could deliver not only voice but also circuit-switched data at download speeds up to 14.4 kbps.
To support mobile multimedia applications, however, 3G had to deliver packet-switched data with better spectral efficiency and at far greater speed.
