5G technology Advantages & Disadvantages as a technical








So what is 5G?

In a nutshell, 5G or 5th generation mobile networks or wireless systems, is the next phase in mobile technology. It promises to improve coverage, battery consumption, and connection speeds, as well as support for other wireless products apart from phones and tablets.

5G needs more investment in infrastructure as it has higher frequency than 4G so the coverage will decrease significantly hence more no of towers required which will make it unfeasible as 4G Macro cells gives coverage of 2 kms and 5G coverage is just 500 to 800 metres.
5G has speed in terms of 5–10Gbps which will easily fill the memory space of smartphones in few seconds and huge size of battery(10000 mAh) is required and heat dissipation will also increase significantly mmWave version of 5G needs Small cells as line of sight between tower and cell phone is required which will be burden to Telecos and Consumers 5G is practically unfeasible for now and it’s not an innovation but an incremental improvement over 4G by increasing frequency.
Wi-Fi is already present as a better Alternative to 5G which is way cheaper and best for Home broadband ,reliable and high speed. Coverage & Speed of both are same.
Secondly VoLTE technology is used for Voice Calls or 2G,3G is used for voice calls there is no such standard for 5G for voice calls till now, there are also limited VoLTE phones in world.

Important Advantages

There are several advantages of 5G technology, some of the advantages have been shown in the above Ericsson image, and many others are described below −
  • High resolution and bi-directional large bandwidth shaping.
  • Technology to gather all networks on one platform.
  • More effective and efficient.
  • Technology to facilitate subscriber supervision tools for the quick action.
  • Most likely, will provide a huge broadcasting data (in Gigabit), which will support more than 60,000 connections.
  • Easily manageable with the previous generations.
  • Technological sound to support heterogeneous services (including private network).
  • Possible to provide uniform, uninterrupted, and consistent connectivity across the world.




Disadvantages of 5G Technology

Though, 5G technology is researched and conceptualized to solve all radio signal problems and hardship of mobile world, but because of some security reason and lack of technological advancement in most of the geographic regions, it has following shortcomings −

  • Technology is still under process and research on its viability is going on.
  • The speed, this technology is claiming seems difficult to achieve (in future, it might be) because of the incompetent technological support in most parts of the world.
  • Many of the old devices would not be competent to 5G, hence, all of them need to be replaced with new one — expensive deal.
  • Developing infrastructure needs high cost.
  • Security and privacy issue yet to be solved
