5G is going to be the next telecom revolution where everything from cars to other household appliances will be connected to the web. For this, it will require an incredible amount of speed along with efficiency. That’s where the upcoming 5G network will shine in comparison to the traditional 4G and the 3G networks available now.
Gartner predicts that around 20.8 billion devices will be connected to the web by 2020. If we compare this to our current situation, there are around 6.4 billion connected devices. In our previous post, we talked about the 5G (G for generation) wireless network and how it paves the path for the future IOT (Internet of Things). In this post, we will be talking about the speed of the 5G network and how much it is faster than the current best 4G network available now.
With the advent of 4G networks, people can now browse the web, make calls and also download and upload large files without worrying about data usage. 4G networks were widely adopted and became more traditional than wireless networks like WiMax and LTE, though there are not many differences between them. 5G networks will be built on the same foundation of 4G networks. Except that there will much more devices and people will be able to download and upload 3D and ultra HD videos much faster.
5G is Much Faster than 4G
Now our current 4G networks top speed about 1 Gbps per second which means it takes around one hour to download a good HD movie.(Note that the speeds fluctuate due to trees, buildings, radiation etc.). 5G networks will deliver download speeds up to 10 Gbps per second which means the same file will be downloaded in some minutes. So it will be saving a huge amount of battery power.
How Does it Work?
Usually, when a new network arrives, it is assigned to a higher frequency. 4G occupies the frequency band to 20 MHz so that the 5G networks will be assigned to frequency bands up to 6 GHz. It is done because these frequencies are not in use and hence deliver the much better result. Now the problem is higher frequencies don’t travel as far as the lower ones, so multiple input and output (MIMOs) will likely be used to boost the signal strength.
