4G to 5G: The technical challenges

Speed is everything, whether it’s of vehicle or mobile networks. Generation is moving forward day by day in every phase of life, so why network generation would stay behind in this advanced world.

While 4G LTE is a big selling point for various wireless carriers, they are now eyeing on 5G coverage. Think of 5G as the next generation of wireless connectivity that will eventually overcome 4G coverage. 5G is expected to provide a wide range of benefits to their cellular users.

Its exponential boost in data speeds could be measured in gigabits per second rather than megabits per second and is likely to be faster than 100 times than 4G OR LTE speeds meaning the programming which used to take minutes to download would get download in just few seconds. Low latency is not often discussed but low transmission latency is one of the reputed factor that makes 5G so important. Latency is the time it takes for a signal to be beamed from a tower and received by a device. This technology is of absolute necessity in the world of internet of things to give new devices and refrigerators, lights, the connection speeds they require. Without 5G,  it’s hard to imagine internet of thing reaching its heights.

Like its predecessors, 5G will first come to developed countries. In fact, china is still trying to roll out their 4G LTE.

5G networking is anticipated as the next major evolution for mobile technology, empowering customers with even faster data connections and even helping to build widely connected “smart-cities”. It’s the crucial next step in better connecting our increasingly technological world, but there’s still plenty of legwork left to do before this all becomes a reality. Implementing 5G has its challenges – it will require exploiting millimeter wave frequency bands, which has been formidable so far. Here’s more about the 5G technology hurdles the wireless industry is working to surmount.     

Backhaul will be a major challenge in the migration from existing networks to 5G with less than 20 per cent Indian networks running via fibre optic cables.

“One of the fundamental requirements for 5G is strong back haul, which is simply not there and that is the most time consuming part and it is extremely expensive in today’s condition in India

The problem is, in India, more than 80 per cent of cell sites are connected through microwave back haul, while under 20 per cent sites are connected through fibre. Microwave back haul has bandwidth issue since it uses traditional bands providing 300 Mbps of capacity

But, what is back haul?

Back haul is a network that connects cells sites to central exchange. It is basically the intermediate links between the core (or backbone) network and the small sub-networks. 

While the commercial launch of 5G technology is still some time away (2019-2020), there is a whole new infrastructural change that the telecom sector has to invest in, before this dream turns into reality. At present, the condition of our existing data infrastructure is rather poor.

The fact that our telecom industries are still struggling even with the 3G and 4G connections, it would be the dream come true to access 5G in this country of infrastructural backwardness.

Well future is right in front of us but its still way out of reach.
