The term ‘5G’ refers to the fifth generation of wireless technology. Every new number that precedes ‘G’ brings rapid advancements while also calling for updated infrastructure and technologies.
The switch from 3G to 4G delivered faster downloads and improved functionality (especially with Long Term Evolution, or LTE), but the move from 4G to 5G could be even more impressive. Experts believe the new 5G wireless network will deliver faster speeds and the ability to move more data. Additionally, 5G networking will reduce latency (lag time), thereby increasing responsiveness.
