The main difference between 3G and 4G is speed – 4G brings broadband to your phone. If you want to future-proof your mobile communications and entertainment, you need 4G, with speeds of up to ten times faster than 3G.
4G Network speed : 100 Mbps for high mobility like service from a moving car. 1 Gbps for low mobility like when walking or not moving at all
3G Network Speed : 7.2 Mbps or 52 Mbps on 3G HSPA+
The technical bit
Average speeds on EE’s 4G network are 12-15Mb/second. The UK average for 3G is 1.5Mb/second.
We’re rolling out a new enhancement to our 4G network, so average speeds will be twice as fast as today – 24-30Mb/second. And top speeds are up to 60Mb/second.
Upload speeds will also be doubled to 11Mb/second. We can do this because we have sufficient portions of 1800 spectrum to upgrade our customers to 2×20 MHz from the current 2×10 MHz they use today. It’s like adding two additional lanes of traffic to a road and changing the speed limit, meaning you can get more cars travelling on it, at faster speeds.
Newer generations of phones are usually designed to be backward-compatible, so a 4G phone can communicate through a 3G or even 2G network.
4G mobile networks, though advantageous, also comes with its disadvantages. While this technology is evolving speedily, it would still take its time to emerge as the most popular network. Mobile carriers and users interested in investing in 4G would do well to analyze and understand its pros and cons before adopting in this new technology.
