What is 5G? All you need to know about it!!!

5G is the 5th generation of wireless network and it is having the potential to change the world. With Verizon(American network provider) announcing that 3 to 5 American cities will get 5g and Sacremento and Los Angeles have been confirmed to get 5g by the end of this year and also Sprint confirming to bring 5g to New York, Phoenix and Kansas City in 2019. So what really is 5G, let get into this!!!

What is 5G

5G end to end Strategy

5G networks are the latest mobile internet connectivity, which will offer faster internet speed better and reliable connections on smartphones and other devices.

5G is based on cutting-edge network technology and the very latest research, it will use millimeter wave technology. 5G will offer connections that are 100 times better and faster than current connections, with the average download speed of 1GBps expected to be normal.

With 5G the response time will also be much better, today in 4G the response time is 0.045 milliseconds but with 5G the response time will be only 0.001 milliseconds which is 400 times faster than a blink of an eye. The reduction in response will help many new technologies to be better such as Self Driving Cars which require continuing stream of data, the quicker the information is delivered, the better and safer they can run.

5G technology is driven by 8 specification requirements

  • Up to 10Gbps data rate  – > 10 to 100x 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 devices

Millimeter wave

5G speed

 

All cellular networks use airwaves to ferry data over the air, with standard networks using spectrum in lower frequency bands like 700 megahertz. The higher the frequency is the higher the speed you can achieve but there is a problem with it when you get the higher speed it will shorten the range.

To achieve the high 5G speeds, you really need high-frequency spectrum, The millimeter wave range falls between 24GHZ and 100GHZ.

The problem with the Super High-Frequency spectrum besides the short range is that it is finicky, the waves will not be able to cross the walls, you will get a lot of interference even because of the moisture in the air you will a lot of interference. Companies like Verizon are working on using software and broadcasting tricks to get around these problems and ensure stable connections.

Hurdles of 5g

It is said 5G can become mainstream by 2020 but will still lag behind 4G and 3G until 2025.

There are multiple hurdles for setting up for 5G, the most significant of this one is cost, and some analysis says that the network providers had to tear up their current business models in order to make business sense out of 5G. For e.g. in the United Kingdom, 3G and 4G were easy to set up because they were able to roll out on existing radio frequencies, but for 5G to work properly it requires a need of much bigger bandwidth(Super High Frequencies) which would indeed require brand new infrastructure.

And some analysts also believe due to its high cost some of the network’s providers to share the use and management of the mobile network.
