What is 5G? 5G is the fifth-generation mobile broadband which enables multi-Gbps peak data rates, fast response time referred to as latency and massive network capacity. Like everything else it has some disadvantages.
Operating Band/Working Principle
Unlike other generations of mobile technology, it operates on three spectrum bands. Let us discuss them briefly.
Low Band Spectrum
5G with a low band spectrum operates in the frequency range below 2GHz. In the US this band is primarily used by carriers for LTE. So low band 5G will be slow as the bandwidth is nearly depleted or used up. These frequencies are used in the oldest cellular and TV network. Although 5G operating in a low band spectrum has the ability to cover a large area and has high penetration power, the peak data rate will not go beyond 100Mbps.
5G with mid-band spectrum (also called sub-6) operates in the 2-10GHz frequency range. Despite the faster speed and low latency than the low band, it has the drawbacks of penetrating walls and coverage area. We can achieve a maximum speed of about 1Gbps on the mid-band spectrum. In order to increase the penetration power and coverage area, it uses massive MIMO and Beamforming technology. 5G will be benefited by the mid-band spectrum as it is already licensed for wireless data transmission.
High Band Spectrum
5G sometimes referred to as millimeter wave operates in the frequency range between 20-100GHz.As 5g uses a high band spectrum it offers peak data rates up to 10Gbps with extremely low latency of about 1ms. The main disadvantage of 5G is low penetration power and small coverage area that is 0.7 miles in urban areas. To increase the coverage of 5G network small geographic area is filled with low power base stations combined with beamforming. For example, Verizon relies completely on the high band which it calls “ultrawideband”. AT & T has some in small parts of 35 cities. T-mobile has a bit more broadly in 7 cities.

What is 5G Application And Use Cases
The rollout of 5G technology will have advantages in three major sectors also known as the “5G triangle.”
- uRLLC : Ultra-Reliable Low Latency Communication use cases.
- mMTC : Massive Machine Type Communication(IoT) use cases.
- eMBB : Enhanced Mobile Broadband-high speed use cases.
uRLLC-Ultra-Reliable Low Latency Communication Use Cases
The above use case that offers high reliability and low latency will be a game-changer when 5G is installed. Now we will discuss the application that requires an instant response and high reliability.
The most probable 5G application includes autonomous vehicles. In order to make autonomous vehicles practicable many developments in data throughput, network speed, vehicle technology, and machine learning must combine together. Due to the sensational reduced latency, the response time is 10-100 times faster than a current cellular network which makes vehicles to everything(V2X) communication network possible. The reduced response time helps in reacting to objects and changes around them instantaneously in order to avoid possible danger.
5G IoT In Smart City Infrastructure And Traffic Management
An intelligent transportation system is willing to support connected vehicle technology which will manage vehicle congestion and routing emergency vehicles. In order to established safety in transportation system connected vehicle technology comes in handy because it will enable both way communication from vehicle to vehicle, V2V, and vehicle to infrastructure, V2X.
The major advantage of 5G in industrial automation areas are reduced operating cost, wireless flexibility, and viability of the application that are not possible with current cellular network technology
Augmented Reality And Virtual Reality
The AR and VR applications become more immersive and far more interactive because of the low latency of 5G technology. For example, we can arrange AR meetings that do not require your physical presence and yet more interactive as if you are in the same meeting hall with other members which is way better than video conferencing. 5G promises a more immersive future for gamers. The rise of high definition live streaming becomes possible with 5G speeds.VR application powered by 5G gives more realistic experience as they depend upon fast feedback and response time.
mMTC- Massive Machine Type Communication(IoT) Use Cases
In the present scenario, the IoT connected devices per person is 2 and will rise to 10 by 2025. This requires 5G enabled devices for better performance.
Application With mMTC – Wearables And Mobiles
5G will be capable of operating multiple devices seamlessly(without delays, dropped calls, and more) in a particular area. This property of 5G benefits wearables, trackers, and sensors in the near future. As we have mobile devices, tablets, and laptops, gadgets, appliances and machines connected with 5G they will interact with each other without delays and makes our daily life easier.
eMBB-Enhanced Mobile Broadband-High Speed Use Cases
With high-speed use case of 5G, it provides broadband like services, such as high definition streaming video without noticeable buffering. The primary connection will be wireless as 5G comes into existence because of its high bandwidth, reliability, and low latency.
