What is 5G ?
5G simply stands for fifth generation of mobile or wireless system. 5G technology includes all types of feature which will make it most powerful technology.
5G-technology includes camera, video recording,large phone memory ,video player , dialing speed and many more feature that user never imagine..5G also increase the network expandibility upto hundreds of thousands of connection.
The signal technology has also improvedfor 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 type of devices which could cause 4G echosystem to be fragmented and overcrowded.
5G will provide better speed and coverage than 4G. 5 G operates with 5 Ghz signal and it is set to offer speed upto 1GB/s for tens of connection.
5G provides speed 100x faster than 4G LTE provides. 5 G will increase the download speed upto 10 gbps. If any one want to download the HD movie it can be download within few seconds while if we are using 4G it will takes about an hour to download the same movie.
Comparision Between 4G and 5G :
|Full Form||Fourth Generation||Fifth Generation|
|Data Bandwidth||2Mbps to 1Gbps||1Gbps and higher as per need|
|Frequency Band||2 to 8GHz||3 to 300 GHz|
|Standards||AI access convergence including OFDMA, MC-CDMA,network-LMPS ||CDMA and BDMA|
|Technologies||Unified IP ,seamless integration of broadband LAN/WAN/PAN and WLAN||Unified IP ,seamless integration of broadband LAN/WAN/PAN and WLAN and advanced technologies based on OFDM modulation used in 5G.|
|Service||Dynamic information acccess,wearable devices,HD streaming,global roaming||Dynamic information acccess,wearable devices,HD streaming ,any demand of user.|
|Core Network||All IP network||Flatter IP network,5G network interfacing|
|Handoff||Horizontal and Vertical||Horizontal and Vertical|
|Downloading speed||1 gigabytes per second.||10 gigabits per second.|
|Switching Technique||Circuit Switching and Packet Switching||Circuit Switching and Packet Switching|
|Initiation From||Year 2010||Year 2015-2020 onwards|
5G-Technology and Internet of Things :
5G will play fundamental role in Internet of Things:
Internet of Things will be the ideal application of 5G.What currently stands in the way of the IoT are disconnected system. For example , we have RIFD we have short range communication techniques UWB, Bluetooth etc.This will be a problem in future if we talk about smart city where a unified framework for seamless connection is required. 5G is a good opportunity to provide this unified framework.
How 5G 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 br first deployed in major metropolitan areas so IoT application it will be first used to connect smart city solution like smart street lights trafic 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 network limits many IoT application.Now many IoT solution use cellular network like 4G LTE to connect to the cloud but these devices produce huge data which becomes hard to process quickly.That creates high latency – amount of time between when data is sent from connected device to when it return to same device- which in turn limits IoT solution effectiveness.
- 5G could solve that leading to increasing efficiency and the potential more connected devices.since 5G is able to transmit data.
How will 5 G deal with huge number of device connected to the IoT and will there be sufficient bandwidth?
Currently there is lots of research how we can devlope non orthogonal multiple access by putting number of user into the limited bandwidth channel.
In IoT there are many device which 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 ny these devices are not likely high.
By using non-orthogonal multiple access, we can squeeze in lot of IoT user/devices with different quality of service requirements into the same time slot or frequency channels.
