4G was Introduced in the year of 2009, devices featuring 4G connectivity are currently the most popular with consumers in developed countries. Known also as the Long Term Evolution (LTE) standard, 4G networks transmit data at downstream rates of up to 53.3Mbps.

Design priorities for 4G service have focused on improved reception, fewer dropped data packets, reduced network latency and faster throughput. Another requirement for technologies based on this standard is enhanced interoperability with the IoT through an exclusive use of IP packets for data transmission. End user applications connected through 4G networks include fully mobile web access, Voice over IP (VoIP) telephony, real-time gaming and high-definition video for streaming and conferencing. The term “LTE” implies that 4G usage will continue to proliferate even as next-gen standards become available.
