Introduction

    5G Wireless Technology is the 5th generation of mobile networks and an evolution from the current 4G LTE networks. It is specially designed to fulfill the demands of current technological trends, which includes a large growth in data and almost global connectivity along with the increasing interest in the Internet of Things. In its initial stages, 5G Technology will work in conjugation with the existing 4G Technology and then move on as a fully independent entity in subsequent releases.

    5G Wireless Technology is now the latest cellular technology that will greatly increase the speed of wireless networks among other things(And who doesn’t want that?!!). So the data speed for wireless broadband connections using 5G would be at a maximum of around 20 Gbps. Contrasting that with the peak speed of 4G which is 60 Mbps, that’s a lot! Moreover, 5G will also provide more bandwidth and advanced antenna technology which will result in much more data transmitted over wireless systems.

5th generation technology offers a wide range of features, which are beneficial for all group of people including, students, professionals (doctors, engineers, teachers, governing bodies, administrative bodies, etc.) and even for a common man.
Benefits of 5G:

    5G Wireless Technology will not only enhance current mobile broadband services, but it will also expand the world of mobile networks to include many new devices and services in multiple industries from retail to education to entertainment with much higher performances and lower costs.

• 5G will make our smartphones much smarter with faster and more uniform data rates, lower latency and cost-per-bit and this, in turn, will lead to the common acceptance of new immersive technologies like Virtual Reality or Augmented Reality.

• 5G will have the convenience of ultra-reliable, low latency links that will empower industries to invest in more projects which require remote control of critical infrastructure in various fields like medicine, aviation, etc.

• 5G will lead to an Internet of Things revolution as it has the ability to scale up or down in features like data rates, power, and mobility which is perfect for an application like connecting multiple embedded sensors in almost all devices.

Parameters of 5G:
Peak data rate

At least 20Gbps downlink and 10Gbps uplink per mobile base station.

Real-world data rate

Download speed of 100Mbps and upload speed of 50Mbps.

Spectral efficiency

30bits/Hz downlink and 15 bits/Hz uplink. This assumes 8×4 MIMO

Latency

Maximum latency of just 4ms (compared to 20ms for LTE)

Connection density

At least 1 million connected devices per square kilometre (to enable IoT support)

Advantages of 5G:

• 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 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

Conclusion

    The 5G Technology provides a comprehensive review of some recent initiatives toward a green, flexible, and mostly dominant 5G mobile communication standard. Important issues, from an improved substitute for OFDMA to energy efficient D2D communication research endeavors, were briefly described. However, there are many issues that could not be presented because of space limitations.
