How 4G/LTE technology work



How 4G/LTE technology work

Before I do justice to the topic, permit me to explicitly define what 4G and LTE is and equally add how the technology work.

The terms I want to explain are mainly linked to mobile phones so in essence, this post will actually let you know the browsing speed of your mobile device because that is why 4G and LTE exist. They are two separate terms but they go in hand with each other.

WHAT IS 4G?

Literally, 4G stands for "fourth Generation" which has 100% effect on the wireless browsing speed of a mobile device.

Prior to 4G, there have been other generations of wireless browsing speeds and they are 1G, 2G and 3G, and they mean first generation, second generation and third generation respectively.

 1G gave rise to 2G because of its slow dial up. The former, 1G started toping its processing speed from 600 bps to 1200 bps then 2400, 4800, 9600, on up to maybe 14,400 bps.

2G or maybe second generation wireless network started from the speed of 14,400 to 56k range and its speed is currently within 128 Kbps to 256 Kbps.

3G started the megabyte per sec level and is roughly 1 to 1.5 Mbps and possibly as high as 3 or 4 Mbps.

4G which is our bone of contention is faster than the above generations mentioned. Its browsing speed is above 4.7 Mbps and also 10 times faster than 3G.

 It may interest you to note that 4G came as a result of the high demands of a fast browsing speed to stream videos online and also to download heavy data from the internet.

 You can also say that 4G is the fourth generation of mobile data technology introduced by the radio sector of the International Telecommunication Union (ITU-R).

ITU-R issued some standards required of 4G connections and they are, for smartphones and tablets, connection speeds need to be atleast 100 megabits per second, and for mobile hotspots, its browsing speeds need to be at least 1 gigabit per second.

What is LTE?
Talking about LTE, it is the acronym for Long Term Evolution. Lets say that LTE helps 4G to establish its speed because the standard speeds set by ITU-R was never achieved.

Long Term Evolution was introduced by ITU-R as the path followed in pursuit of those standards to attain a fast 4G connection.

As stated before, LTE is just a path and not a technology to achieve a fast 4G connection, we have other paths like WIMAX, HSUPA, HSDPA, HSPA, and HSPA+.
