RE: difference between 2g and 3G in mobile phone testing
In 3G Internet connection is faster better call quality Video and Audio services but drains battery life quicker (twice as fast). Moreover coverage area is less than in 2G.
RE: difference between 2g and 3G in mobile phone testing
2G and 3 G is a family of standards for mobile telecommunications defined by the International Telecommunication Union which includes GSM EDGE UMTS and CDMA2000 as well as DECT and WiMAX. Services include wide-area wireless voice telephone video calls and wireless data all in a mobile environment.
2G Stands for second generation mobile telephony standards where 3G defined the third generation mobile telephony standards to facilitate growth increase bandwidth and support more diverse applications.For example GSM (the current most popular cellular phone standard) could deliver not only voice but also circuit-switched data at download rates up to 14.4 kbps. But to support mobile multimedia applications 3G had to deliver packet-switched data with better spectral efficiency at far greater bandwidths.
