3G definition

3G definition is one more answer in our little School blog category. 3G stands for third generation of mobile telephony, or mobile telecommunication services. With 3G support you can enjoy in mobile internet access, mobile TV, video calls, wide area wireless voice telephone, instant downloading email content with attachments, etc.

By 3G definition, there are some technical standards which has to followed: IMT-2000 standard requires minimal amount of data rates for 2Mb (200Kb/s), or 128 Kb/s in a car. It can provide "speed" up to 3Mb/s which will take 30 seconds to download 6 minutes song.

This was only beginning of development. In 3G definition, we have to include and advanced technology in 3G family: 3GPP and 3GPP2.

The 3rd Generation Partnership Project (3GPP) was founded 1998, developing General Packet Radio Service (GPRS) with 114 Kb/s (2000), Enhanced Data Rates for Global Evolution (EDGE) up to 384 Kb/s (2003), Wideband CDMA (WCDMA) speeds up to 1.92 Mb/s, High Speed Download Packet Access (HSDPA) up to 14Mb/s, LTE Evolved UMTS Terrestrial Radio Access (E-UTRA) is aiming for 100 Mb/s.

3GPP2 technologies include:

One Times Radio Transmission Technology (1xRTT) with speeds up to 144 Kb/s, Evolution Data Optimized (EV-DO) up to 2.4 Mb/s, EV-DO Rev. A - 3.1 Mbps, EV-DO Rev. B 4.9 Mb/s, Ultra Mobile Broadband (UMB) with speed up to 288 Mb/s.

3G technology allowed new smartphones to work better and faster, giving us more flexibility and option to have mini-computers in our hands. 3G definition evolved into the 4G, giving us even more speed and more flexibility.
