5G Wireless Technology

5G is the fifth generation technology standard for broadband wireless networks in telecommunications, which cellular phone companies started deploying internationally in 2019, and is the intended counterpart to the 4G networks that offer access to most existing cellphones According to the GSM Organization, 5G networks are expected to have more than 1.7 billion subscribers worldwide by 2025. All 5G wireless devices in a cell are connected by radio waves via a local antenna in the cell to the internet and telephone network. The key benefit of the new networks is that they will have greater capacity, offering higher download speeds, potentially up to 10 gigabits per second (Gbit/s). Due to the improved bandwidth, it is anticipated that the networks will not only support mobile phones like current cellular networks, but will also be used as general providers of laptop internet services. Competing with existing ISPs such as the wired internet, and emerging technologies in the Internet of Things (IoT) and machine to machine areas would also be feasible. The new networks that require 5G compliant wireless devices are unable to use 4G mobile phones.

What is 5G?

  • 5G innovation is a revolution.
  • The next generation of mobile networks (fifth generation or 5G) began to enter the market at the end of 2018 and will continue to evolve globally.
  • The technology is expected to unleash a huge 5G IoT (Internet of Things) ecosystem beyond speed improvement, where networks will serve connectivity needs for billions of linked devices, with the right trade-offs between speed, latency, and cost.

 

5G technology is driven by the criteria of 8 specifications :

  • Data rate of up to 10Gbps ->10 to100x performance boost over 4G and 4.5G networks
  • Latency of 1-millisecond 
  • 1000x bandwidth per area of a unit 
  • Up to 100x number of devices connected per unit area (compared with 4G LTE) 
  • Availability 99.999 percent 
  • Coverage of 100 percent 
  • Reduction of 90 percent in network energy consumption 
  • Battery life for low-power IoT devices up to 10 years

 

 

How fast is 5G?

  • The maximum speed of 5G is 10 gigabits per second (Gbps)
  • 5G is 10 to x100 faster than what 4 G will give you

 

 

What makes 5G faster?

The shorter the frequency, the greater the bandwidth, according to communication standards. For 5G networks .The use of shorter frequencies (millimeter waves between 30GHz and 300GHz) is why 5G would be quicker. Not Only in speed but also in power, low latency, and efficiency, this high band G spectrum provides the anticipated boost. However the download speed of 5G can vary widely by country. According to Fortune Magazine’s February 2020 issue, the average 5G speed measure taken in Q3/Q4 2019 varies from:

  • In Las Vegas, 220 megabytes a second (Mbps) New York 350,
  • Los Angeles 380,
  • 450 from Dallas,
  • To Chicago 550,
  • And roughly more than 950 in Minneapolis and Providence

Applications of 5G Technology

  • IoT Internet of Things —5G would provide greater coverage for the increasing number of network-using personal devices (such as wearable technologies) and IoT devices.
  • Online gaming and VR — Thanks to latency and bandwidth, 5G would promote the creation of new online gaming platforms and give end-users the best experience.it will also be a central factor in the performance of the forthcoming Virtual Reality applications. Many major players in the IT industry, such as Facebook, are hoping for the rapid and wide introduction of 5G networks
  • Cloud and video streaming (4K/8K, 3D) – 5G technology can provide end users with better experience when using cloud storage services and streaming channels to view 3D videos or other ultraresolution content, such as 4K or 8K. Theoretically, the speed of the 5G network should be 10Gbps in download and 1Gbps in upload.

Conclusion

  • The technology of 5G is promising to be ground breaking. Larger bandwidth and low latency times would allow the creation of new services and the enhancement of existing ones. The requirements for the 5G standard are set out in the latest Draft Report ITU-R SG05.
  • The standard itself should be established by 2020, however the first business implementations are planned by 2022/2023.However these dates are just projections and some countries will definitely see the launch of 5G networks and mobile devices ahead of others.
