How Does 4g Actually Work and Why 5g is Stronger

For the past few years, there has been some controversy associated with the introduction of 4g and 4g. Many people believe that the introduction of the two may lead to environmental catastrophe whereas many others simply do not understand what either really is and how they work.

We were first introduced to the two before they were even created, with many of us depending on the use of 3G for a number of years. Many of us never even considered that mobile internet would evolve past this and when it did, we were all left with a lot of questions. When 3g moved onto 4g, many of us sought out to have the difference between 3g and 4g explained. Even if we were not able to fully understand how either works, it was easy to get a general understanding of the improvements that came with the introduction of 4G.

With 5G being introduced during a period where we have nothing to do aside from question the world around us, many of us have become hyper-aware of the thousands of warnings and bouts of graffiti that are being plastered everywhere that expresses the world’s disdain towards 5G. With that being said, many people are looking to gain a further understanding of how both 4G and 5G works and the differences between the two.


What is 4G

4G stands for ‘fourth generation communications system’ and was the standard for mobile data technology, that was until 5G was introduced. 4G is used by mobile networks to transmit data between phone masts. 4G was introduced with the promise of fixing the two biggest issues that were encountered when using 3G, which were speed and network congestion. 4G was launched in 2012 and up until recently has managed to deal with the workload of all of the users out there. All major phone providers use 4G and will continue to have it as an option.


How does 4G work?

If you are familiar with the way in which 3G works, then you are in luck as 4G works essentially in the same way, just faster. 4G gives you speeds that are comparable to your wifi, which means that you can experience the same speeds when you are away from home and you’re using your mobile device. 4G allows users to reach speeds of up to 21MB on the go, which is often much faster than the speeds that you can achieve at home. However, this can be dependent on your location. For example, you can expect to experience a faster 4G when you are in a larger city with plenty of masts. However, if you are in more of a rural area, then you will experience slower internet with your 4G.

4G depends on the use of masts and can be best compared to an advanced radio system.  Masts are large towers that are dotted around the country and these masts emit signals which are made up of a large quantity of data. The more data that is within these signals, the faster and more efficient the network is.

4G is entirely IP-based, this basically means that it uses internet protocols for data. 4G conforms to one standard, which means that data is far less likely to become scrambled while moving between networks, which means it gets a lot less fumbled along the way. 4G can support a greater amount of users, which has really catered to the world which has only continued to see increases in the number of people using mobile devices.


What is 5G

5G is the latest digital system which is used to transport data from masts to phones. 5G uses a new radio interface that utilizes much higher radio frequencies that match up with the continuously evolving technology of today. The higher radio waves that come with 5G means that there are much faster speeds and far less congestion. This means that data transfer happens with very little delay.

5G also means that more and more devices can be used within the same area, which means that the increased popularity of people using smartphone devices will not impact the quality of the internet. 4G is estimated to be able to support around 4,000 devices per square KM, whereas 5G will be able to support one million people. Obviously, this is an extremely big leap in the world of data transfer and is an extremely large improvement in terms of coverage.

5G is said to be a leap forward for tech-based areas and smart cities. Right now, even though 4G is still quite powerful, it is impossible to have too many devices operating in one area as there is only so much data the masts can handle. 5G promises that this will never be an issue again.
