What is fifth generation technology important component of 5g next generation Mobile communication network
5g network is under research and developing mode or we can say research is almost over and development and implementation is just started or about to start at some countries.
What is 5g network?
5g stand for fifth generation wireless technology for mobile. But it can use which other gadgets and other services.
5G IMT 2020 -International mobile telecommunication and 20 means need of 20Gbits speed.
4G LTE / wimax -long term evolution standard for 4g mobile technology which is 10 time faster compare to 3g.
3g – UMTS - Universal mobile telecommunication services standard for 3g
2g - GSM global system for mobile communication
1G to 5G
At the time of 1st generation we use analog technology for communication like pager. In 2G we started sms and messaging services. In 3G we started mobile browsing photo sharing and in 4G live video sharing. In 5G we have immense scope.
Who support in development of 5g network infra structure?
There are many organizations working on 5g network. All big names of smartphone and electronics field are contributing to develop and implementation of 5g. Qualcomm, Intel, Huawei, Samsung , Nokia, Cisco, Zte and along with this there are Verizon, T-mobile, At&t, Vodafone, Telstra, China telecom, south Korean telecom, sprint, NTT docomo, bell, Vodafone, telus and Japan telecom. USA, Japan, some part of Europe, South Korea, China are keen to rollout 5g network as early as possible as it can gain economical growth of country. Though other Asian and gulf countries are also planning for this. Europe also working fast on 5g development.
Spectrum frequency used by 5g network
5g work on super high frequency. It works on millimeter wave band range from 24 to 86 GHz. And it also support present 4g lte band 600Mhz to 6Ghz. Higher frequency higher pulse more faster data transfer and lower latency is the base of 5g network. For example when you write website address to your browser and clicks enter. You will see at lower left side that waiting for response, data transfer and reading. This is the response time to your command it is 20 milliseconds or less depend on your network and it is called latency. But in 5g network it is 1millisecond or less. So you just click and site loaded.
Core concept and heart of 5g technology
Open Network Foundation has developed and standardize 1) SDN -Software Defined Networking.
It uses open flow protocol so you don’t need to manage all devices and vendor specific code or protocol. So network management and control become easy and more speedy. It supports very high bandwidth. And transmitted data package has less latency as network design instruction is developed by SDN itself. Sdn is future architecture of networking and it simplifies cloud computing, network transmission and bandwidth management.

2) NFV Network Function virtualizations
– SDN and NFV combined together makes service provider communication faster make 20Gbit speed realistic. As to improve speed and performance by software is less costly, easy to implement and allow centralize control. While using hardware it will costlier, ask more effort and more difficulty for installation. When you design software, it is one time cost while to make hardware you need to invest for every piece. For example you have 10 mobile you need 10 screens. But you can install software os android pie 9 on 10 mobile for free. Software don’t cost for each pieces. Software is digital transfer while hardware is physical transfer.
5G NR
5G nr / 5g new radio is radio air interface developed for 5g mobile communication. It can also use low frequency band like we are using in 3g and 4g. But in lower frequency we would not get 20Gbits speed.
MIMO Multiple input multiple output.
In 5g it is massive mimo. Mimo is antenna technology used in wireless communication. Mimo allow multiple antennas within wifi architecture. Which make many data steam within single channel which increase speed, flexibility and faster data communication. Nokia airscale use 64T64R massive mimo. This improves network efficiency, uptime, throughput, allow more simultaneous connection at Gbit high speed.
Network slicing
Slice means cut in small pieces. Network slicing allows many logical networks within physical structure. This increases flexibility, more control and better transfer rate within network. This is very useful in cloud and broadband network.
