5G Radio Access Network (RAN) Networks | How O-RAN Technology works!

5G RAN Technology 2021: RAN is currently one of the topics of discussion. This is basically an abbreviation. The whole word is Radio Access Network. This term associated with the telecom sector will play one of the most important role in the mobile communication system of tomorrow.

The quad countries, including India, have held a discussion on introducing RAN among themselves. It is expected that RAN will be launched soon. Before that let us know the various details of RAN system.


5G RAN Technology 2021; What is OPEN RAN?

Simply put, mobile communication systems and the various software and hardware associated with them are included in the RAN. When someone calls from a mobile, the signal from the mobile phone reaches the antenna attached to the tower. On the other hand, different signals come out of the antenna and come to the mobile phone. This method is called RAN.

There are basically five largest RAN networks worldwide. Who control 95 percent of the world’s mobile networks. Of those five companies, two are Huawei and ZTE. Both are Chinese companies. There are also Ericsson and Noki. The two European companies and the fifth is the South Korean company Samsung. Deloitte recently published a survey on the subject. Of those five companies, Huawei, Ericsson and Nokia control about 80 percent of the RAN.

In this context, the Open Ban Policy Coalition (The Open RAN Policy Coalition) should also be mentioned. This means that the mobile network is set up in such a way that the radio signal, hardware and software are managed by an organization.

5G RAN Technology 2021; What are the benefits of OPEN RAN?

The current problems are mainly in the case of closed RAN. Purchasing a licensed software from a specific vendor means that a network cannot buy software from a RAN vendor for radio signals and hardware from another RAN vendor. That means you have to buy hardware and software from a specific vendor. As a result, to build a mobile network in a geographical area, one has to buy all the hardware and software from a vendor.

After that, if there was any problem in the tower or any problem in any hardware, the whole hardware had to be changed. Which is highly cost effective and time consuming. But there is no need to face these problems in the open ban process.

With the advent of 5G, almost all mobile networks will need to be updated. All systems will need to be reinstalled. In this case, the open RAN experts said, as a result of the open RAN, even if the entire network system will not change.

One of the advantages of the Open RAN process is that mobile communication providers will have the facility to purchase hardware and software from various companies.

How long does it take to start an open RAN?

According to a report released by Deloitte, Open RAN has already hit the market. At the beginning there were only 35 Open RAN architects involved in the world. But now, the market for open RAN is growing.

According to another report, Reliance Jio, Bharti Airtel and Vodafone are working on open RNA. They are basically working on 5G upgrades through open RNA architecture. Open RAN technology will be included in the Make in India campaign launched by the central government.

What is Chin Angle?

There are also questions about Chinese intervention in this regard. It is learned that the central government will make every effort to increase the speed of open RAN technology. But India will take strict action against the use of certain technologies that could harm India’s security. The United States has banned the use of Huawei’s technology and hardware. India has said in the same vein that it will not be allowed to use any technology or hardware that could jeopardize the country’s security. Even vendors that provide such technology will not be allowed.

The reason given is that Chinese companies are run by the Chinese government. As a result, if they use any technology they create, they can monitor with that technology. And can find out various secret information. That is why it has been reported to take technical assistance from trusted companies.

Why ORAN is required for 5G network?

The ORAN model is a very attractive model for mobile communications providers in the case of 5G networks. Currently, ORAN is not started that way among private companies. Currently almost all mobile communication providers use single vendor technology. With the introduction of Open RAN or ORAN technology, every company will be able to implement 5G very easily. This is because there are a number of issues involved in providing 5G services using single vendor technology. But ORAN technology will not have those problems. Because ORAN technology can provide 5G service by changing a few technologies in the tower antenna.

With the use of ORAN technology, private mobile communications providers can easily enhance themselves.

The benefits that ORAN will result in

  • Telecom companies can choose the supplier of their choice from among the suppliers or suppliers.
  • In the case of hardware and other technologies, it is possible to reduce the price a lot.
  • In the case of 5G, multiple aspects like real time data acquisition, robotic and remote operations will be opened up.
  • Multiple avenues will open up for multiple telecom companies to make money.
