What is 5G?
5G is the fifth generation of mobile network technology which provides unique features over the previous generations.

3 Key features (technical goals) of 5G:

1) Enhanced Mobile Broadband (High-Speed Internet)
2) Massive Machine to Machine type Communication
3) Ultra-Reliable and Low latency Communication

These three features will enable new applications and service areas like
1) Internet of Things (IoT)
2) Smart Home/ Smart Cities / Smart Agriculture
3) AR/VR based services
4) Cloud-based Gaming services
5) Autonomous vehicles (Self Driving Cars with very high reliability)
6) Smart Industries

5G frequency bands:

5G technology supports two frequency bands
FR1 : 410 MHz to 7125 MHz (sub 6GHz)
FR2: 24.25 GHz to 52.6 GHz ( mm-wave Band)
* mm-wave frequencies start from 30 GHz, but as 5G frequencies also cover beyond 30 GHz frequencies, it is commonly called as mm-wave band.

Key Technologies behind 5G
1) Massive MIMO
The 5G radios will support an array of antennas, which will increase the reliability, high throughput to end-user, and high spectral efficiency.

2) Network Slicing:
Network Function Virtualization (NFV) enables the network Slicing, where there will be multiple logical networks on top of the physical shared infrastructure.
Different types of services like IoT, low latency communication, high-speed internet can be served on these different logical networks.

Standalone and Non-Standalone 5G
Currently, there are two possible deployment options for 5G.

1) Non-Standalone 5G:
In this deployment, 5G New Radios (NR) will be used to serve High-Speed Data and Voice to users but for control and signaling 4G LTE architecture will be used.
With non-standalone 5G will enable the fast deployment of 5G as existing LTE infrastructure will be used for 5G deployment.

2) Standalone 5G:
In standalone 5G, NR as well the core architecture is 5G.
Standalone 5G will enable the true 5G experience for consumers.

This video will be helpful to everyone in understanding what is 5G and how 5G works?
