## Background.

The next generation of telecom networks (fifth generation or 5G) has started hitting the market end of 2018 and will continue to expand worldwide.
Beyond speed improvement, the technology is expected to unleash a massive 5G IoT (Internet of Things) ecosystem where networks can serve communication needs for billions of connected devices, with the right trade-offs between speed, latency, and cost.

## 5G technology requirements.

Up to 10Gbps data rate - > 10 to 100x speed improvement over 4G and 4.5G networks
1-millisecond latency
1000x bandwidth per unit area
Up to 100x number of connected devices per unit area (compared with 4G LTE)
99.999% availability
100% coverage
90% reduction in network energy usage
Up to 10-year battery life for low power IoT device

## How fast is 5G?

According to communication principles, the shorter the frequency, the larger the bandwidth.
Using shorter frequencies (millimeter waves between 30GHz and 300GHz) for 5G networks is why 5G can be faster. This high-band 5G spectrum provides the expected boost in speed and capacity, low latency, and quality.
However,5G download speed may differ widely by area.
According to the February 2020 issue of Fortune Magazine, average 5G speed measures done in Q3/Q4 2019 range from:
220 megabytes per second (Mbps) in Las Vegas, 
350 in New York,
380 in Los Angeles,
450 in Dallas,
to 550 Chicago,
and over 950 in Minneapolis and Providence approximatively.
That's 10 to 50 times more than 4G LTE. 

## What are the real 5G use cases?

Each new generation wireless network came with a new set of new usages. 
The next coming 5G will make no exception and will be focused on IoT and critical communications applications. 
In terms of the schedule, we can mention the following uses cases over time:
Fixed wireless access (from 2018-2019 onwards)
Enhanced mobile broadband with 4G fall-back (from 2019-2020-2021)
Massive M2M / IoT (from 2021-2022)
Ultra low-latency IoT critical communications (from 2024-2025)
Some critical applications like self-driving cars require very aggressive latency (fast response time) while they do not require fast data rates.  
Conversely, enterprise cloud-based services with massive data analysis will require speed improvements more than latency improvements.

## What is 5G low latency? 

5G technology offers an extremely low latency rate, the delay between the sending and receiving information. From 200 milliseconds for 4G, we go down to 1 millisecond(1ms) with 5G.
At 60 mph (100km/h), the reaction distance is about 33 yards (30 meters) before you pull on the brakes. With a 1ms reaction time, the car would only have rolled a bit more than one inch (less than 3 centimeters). 

## 5G use cases

Use cases associated with low latency are: 
V2X (Vehicle-to-Everything) communication: V2V: (Vehicle-to-Vehicle), V2I (Vehicle-to-Infrastructure), autonomous, connected cars
Immersive Virtual Reality Gaming (5G will bring VR to the masses.)
Remote surgical operations (aka telesurgery)
Simultaneous translating.
