4G: Growth of Mobile Broadband
4G is the 4th generation of broadband mobile communication technology, which was released in 2008. On December 14, 2009, 4G was launched commercially in the world by TeliaSonera telecom operator.
4G technology supports mobile web access with more advanced features. The 4G network provides capabilities defined by ITU in IMT Advanced.
4G technology also offers video conferencing, HD mobile TV, 3D TV, gaming services and other features that demand high speeds.
Fourth-Generation Long Term Evolution (4G LTE)
4G LTE refers to the fourth generation long term evolution that provides a more reliable and fastest connection and higher speeds to mobile Internet experience-10 times faster than 3G. It is worth noting that 4G is faster than LTE.
Voice over LTE (VoLTE)
Voice over long-term evolution (VoLTE) is a specification of wireless technology product that defines data transfer speed rates and standards and complete data transfer procedures for delivering voice communication over 4G LTE networks.

What is the difference between 3G and 4G technology?
The primary difference between 3G and 4G networks is speed. 4G speed is ten times faster than 3G.
The 3G network provides 21 Mbps data bandwidth while 4G offers 1 Gbps maximum data bandwidth and brings broadband to your phone.
3G technology uses a wide-area cell-based network while 4G technology uses a hybrid network architecture.
3G technology uses packet switching for data transmission while 4G technology uses both packet and message switching.
3G networks employ code-division multiple access (CDMA) while 4G networks utilize orthogonal frequency division multiple access (OFDMA).
