What is 5G?

5G simply stands for the fifth generation of the mobile or wireless systems. 5G technology includes all types of features which will make it the most powerful technology.

5G-technology includes the camera, video recording, large phone memory, video player, dialing speed and many more feature that user never imagine..5 G also increase the network expandability up to hundreds of thousands of connection.

The signal technology has also improved for greater coverage as well as spectral and signaling efficiency. Due to such improvements in signaling it can enable changes like pervasive computing, IOT.

Need of 5G :

Now, 4G not only seen in mobile phones it also use in smart-watch, CCTV, doorbells, etc. and initially it never designed to support such types of devices which could cause 4G ecosystem to be fragmented and overcrowded.

5G will provide better speed and coverage than 4G. 5 G operates with a 5 GHz signal and it is set to offer speed up to 1GB/s for tens of connection.

5G provides speed 100x faster than 4G LTE provides. 5 G will increase the download speed up to 10 Gbps. If anyone wants to download the HD movie it can be download within a few seconds while if we are using 4G it will take about an hour to download the same movie.

5 G Technology and Internet of Things:

5G will play a fundamental role in the Internet of Things:

The Internet of Things will be the ideal application of 5G. What currently stands in the way of the IoT is the disconnected system. For example, we have RIFD  we have short-range communication techniques UWB, Bluetooth, etc. This will be a problem in the future  if we talk about the smart city where a unified framework for a seamless connection is required. 5G is a good opportunity to provide this unified framework.

How 5 G will revolutionize the Internet of Things :

5G will be able to transmit the data 10 times faster than 4G LTE. That could revolutionize the IoT .5G will be first deployed in major metropolitan areas so IoT application it will be first used to connect smart city solution like smart street lights traffic light etc. It will connect everything from smart home to self-driving cars and robotics.

Faster data transmission could simply connected device management which means 5G could lead to significant growth in the IoT.

  • Latency in cellular networks limits many IoT applications. Now many IoT solution uses cellular networks like 4G LTE to connect to the cloud but these devices produce huge data which becomes hard to process quickly. That creates high latency – the amount of time between when data is sent from a connected device to when it returns to the same device- which in turn limits IoT solution effectiveness.
  • 5 G could solve that leading to increased efficiency and the potential more connected devices. since 5 G is able to transmit data.

How will 5 G deal with huge number of devices connected to the IoT and will there be sufficient bandwidth?

Currently, there is lots of research on how we can develop non-orthogonal multiple access by putting a number of the user into the limited bandwidth channel.

In IoT, there are many devices that should be served timely with low data rates. for example, wireless healthcare, wearable devices(heart monitor, biosensor)need to send patient data timely to hospital server but the data rates used by these devices are not likely high.

By using non-orthogonal multiple access, we can squeeze in a lot of IoT users/devices with different quality of service requirements into the same time slot or frequency channels.
