What is better to start studying 5G or 4G

Hello,

5G is a new digital system for transforming bytes - data units - over air. It uses a 5G New Radio interface, along with other new technologies, that utilises much higher radio frequencies (28 ghz compared to 700 mhz - 2500 mhz for 4G) to transfer exponentially more data over the air for faster speeds, reduced congestion and lower latency, which is the delay before a transfer of data begins following an instruction.

This new interface, which uses millimetre wave spectrum, enables more devices to be used within the same geographic area; 4G can support about 4,000 devices per square kilometre, whereas 5G will support around one million. This means more Netflix streaming, voice calls and You Tube carried, without interruption, over the limited air space.

5G also uses a new digital technology called Massive MIMO, which stands for multiple input multiple output, that uses multiple targeted beams to spotlight and follow users around a cell site, improving coverage, speed and capacity. Current network technologies operate like floodlights, illuminating an area but with lots of wastage of the light/signal. Part of the roll-out of 5G involves installing Massive MIMO and 5G New Radio to all mobile network base stations on top of the existing 4G infrastructure.

How is 5G different to 4G?

Compared to third generation mobile networking, 4G enabled previously impossible quality video streaming and calling on the go, meaning live TV is now routinely watched on the daily commute. More video streaming, however, has increased congestion in the network.

“4G is reaching the technical limits of how much data it can quickly transfer across blocks of spectrum,” explains Chris Mills head of industry analysis, at Tutela. “A major difference between 5G and 4G is this congestion will be eliminated.” This mean no more five bars of networking signal at rush hour but an inability to access a web browser.

But arguably, 5G’s biggest differentiator to 4G will be as a gateway for the Internet of Things-connected world at scale. Later iterations of 5G networking are expected to be revolutionary for data-driven industries, smart cities and infrastructure management because it will be possible to have many more devices working, reliably, securely and uninterrupted in the same area. Overall, due to the new technologies, spectrum and frequencies it uses, 5G has several benefits over 4G; higher speeds, less latency, capacity for a larger number of connected devices, less interference and better efficiency.

Hope it can help you.

Thanks

¿Cuando se implementara la red 5g en Bolivia?

hmmmmmmmmmmm

Both

Go for 4G but first you need to have a solid understanding of the Telecommunication principle

Dear
You have to star from GSM to 5G

Can't I learn the principles through reading 4G and 5G? if not is there a book that can summarize the principles.

I mostly understand the principles but not in depth, is it required to have deep understanding?

Hi Walead,


Your question: "What is better to start studying 5G or 4G?"
Ideally, you would like to learn in the historical order: first 4G, then 5G...

But. it depends on what you want to do with that knowledge. Service providers all over the world are upgrading their existing systems to 5G, most of these build their networks on top of 4G (still requiring 4G (EPC) core for example)...

To support such an environment - you would need in-depth knowledge of both: 4G and 5G.

But! You may also try an alternative route: to learn the 5G novel aspects first and then (and while you still have time left: to catch up on the 4G) - and if you wait clever enough - the 4G bits and pieces are then long gone... no longer needed ! :)

Interesting (new) gamechanging topics like: 5G MEC, private 5G, 5G components running in cloud (containerized) (so, you no longer need equipment yourselves... just a software-instance running on 'a cloud') and you may start learning to develop for these elements, in that case: no need to learn for 4G, unless you also want to do 4G...

So it really depends on what you seek in career opportunities: for some aspects, everybody needs to learn... even people who already have 2G/3G/4G experience...
