b) EDGE: It is a 2.5G technology. An enhancement of the 2G technology which provides higher data transfer rates compared to GPRS (the default on2G).The speeds can go up to 144 Kbps
c) 3G: 3G technology provides faster / higher data transfer ratescompared to the 2G network (EDGE & GPRS). This technology can offer speeds up to 21 Mbps
d) 4G: This technology rides on LTE platform and is the latest in the world of mobile data transfer. It is the next generation of mobile communications. Currently it is the most advanced technology available. Theoretical data downlink speeds can go up to 100 Mbps..
