5G technology

5G is next generation wireless network technology that’s expected to change the way people live and work.
5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.

The three major benefits offered by 5G are higher speeds, higher bandwidth and lower latency.

Speed is one of the most highly anticipated elements of the 5G network which is expected to be nearly 100 times faster than 4G.
Such high speeds are possible because most 5G networks are to be built on super-high-frequency airwaves, also known as high-band spectrum.
The higher frequencies can transmit much more data, much faster than on 4G.

The 5G network is expected to have significantly more capacity than 4G.
This is because 5G will have greater bandwidth, meaning it can handle many more connected devices than previous networks.
It will bring in an “internet of things” era, filled with connected toothbrushes, kitchen appliances, street lamps and more.

Latency is the time it takes for devices to communicate with each other or with the server that’s sending them information.
Latency is already low with 4G, but 5G will make it virtually zero.
It will be essential for technologies such as self-driving cars which require instant communication of huge data to ensure safety of its passengers.

A small but significant difference exists between speed and latency.
Speed is the amount of time it takes to download the contents of a webpage.
Latency is the time between when a text is sent to another phone and when that receiver’s phone registers that it has received a new message.

The high-band network signals don’t travel very far and struggle to move through hard surfaces.
In order to compensate for those challenges, wireless carriers building high-band 5G networks are installing tons of small cell sites (about the size of pizza boxes) to light poles, walls or towers, often in relatively small proximity to one another.
For that reason, most carriers are deploying 5G city by city.
Significant adoption of 5G is going to take years — industry trade group GSMA estimates that by 2025, around half of mobile connections will be 5G (the rest will be older tech, like 4G and 3G).
There are also concerns among regulators and others about the security of 5G, especially since crucial technologies such as self-driving cars and healthcare systems will be built on top of the network.

The United Kingdom is hoping to form a club of 10 nations that could develop its own 5G technology and reduce dependence on Huawei (Chinese company).
The U.K. is proposing a “D10” club of democratic partners that groups the G7 nations with Australia and the Asian technology leaders South Korea and India.
