What Is 5G Technology?

What is 5G technology?

The fifth generation of cellular network is knocking the door as we enter into a new decade, the last decade was predominantly caught the reflexes of 4G technology, most of the prominent carriers in United states of America have already launched some form of 5G technology, while 4G network started to expand its fangs in early 2010, but proper and correct usage of flamboyant 4G technology was underestimated until apps like snap chat came in 2013, Uber made an entry soon after that, voice calls over LTE was a reality in most of the US by 2013.

As dawn of new decade started, we keenly awaiting the pros of 5G, mooted as the new revolution in network domain, 5G basically runs on three different bands, namely

  • Low band
  • Mid band
  • High band

Unfortunately these bands combined are incompatible, they doesn’t works in tandem, in fact one of these bands under performed in comparison to 4G.

Description of the 5G bands

  • Low band -This band operates at low frequency of GHz, presumably one that were used in traditional TV and cellular networks. Although the range is long, but it have very little channels coverage, in fact it gives the feeling of 4G, mainly due to low speed, few operators have already bundled out this band. In India, Jio info com is leading the race for introducing this 5G band.
  • Mid band -This is next level of low band with frequency range up to 10 GHz, basically good for WI-Fi, it range sometimes goes up to half a mile, in most of the countries including India, the authorities have offered expanded range of 100 GHz. In country like India, 5G mid band could be a massive boon, as it serves the purpose efficiently in rural areas.
  • High band -This is also known as millimeter-wave is basically air waves in range of 20 to 100 GHz. Interestingly this band hasn’t been used for consumer applications ever, with great amount of unused spectrum which can led to very fast internet with usage of 800 GHz, this band is predominantly used as connecting base station with very remote internet links. India this band will presumably have its landfall maybe by 2024.

How 5G works?

Its works in similar fashion like any other cellular networks, its a system of cell sites which divides its territory into different sectors and send encoded data via radio waves. Every cell should be connected to network either wire or wireless connection. An encoding called OFDM is used in 5G, the air interface is designed to low latency than LTE. The ultimate goal is to achieve far higher speeds  the aim is to provide 20 GBPS speed on 1ms latency.

Advantages and disadvantages of 5G technology

With new spectrum comes new age network with its pros and cons, however 5G network gives lightning fast internet speed up to 20 GBPS, it means you download your favourite video within seconds. Unlike 4G it doesn’t congest the network, instead it will give speed independently with powerful bandwidth. But, users have reported lesser penetration of tower signals in high rises, and densely populated areas. 5G compatible phones battery drain very quickly as well. Many users complained about battery issues and also heating of the device during using 5G.

Overall 5G technology is going to take the world by storm in this decade. Things like driver-less cars, self healing bandages were limited to sci-fi flicks would be a reality with innovative 5 technology in coming years.
