How Does Open RAN Work?


Open Radio Access Network (RAN) is a term used for industry-wide standards for RAN interfaces that support interoperability between vendors' equipment. What is Radio Access Network, and how does Open RAN work are topics of interest.  The purpose of using Open RAN is to have a standard of interoperability for RAN elements such as non-proprietary white box hardware and software from different vendors. Operators to avoid using prefer RAN elements with standard interfaces and avoid using a vendor's proprietary hardware and software.

The Open RAN standards under development use virtual RAN (vRAN) principles and technologies. That is because vRAN has several, features such as network flexibility, enhanced security, low capital, and operating costs. So, what else do you need to know about Open RAN, and what is Parallel wireless Open RAN? We will share detailed information about the subject with you in this article.

What are the benefits of Open RAN?

The Open RAN ecosystem gives network operators more choice in RAN elements. With a multi-vendor technology catalog, network operators have the flexibility to tailor the functionality of their RAN to their needs.

A core part of Open RAN standards: digital compliance provides many benefits. For example, with a vRAN infrastructure, network operators can get to market faster than with a hardware-based infrastructure. That is because bringing a new feature to the network is as easy as updating remotely to the network's VNFs. Also, with the virtualized aspects of the Open RAN architecture described above, network administrators can benefit from improved network visibility.

Some vendors in the RAN market aim to demonstrate how integrating RAN elements provides greater efficiency and lower latency. Open RAN standards increase the chances of new equipment vendors entering the market. New vendors will encourage competition and, in theory, benefit customers by reducing costs.

Why is open RAN Significant for 5G?

Telecom companies have long complained about high infrastructure costs. This problem has become much more severe with the rush to deploy 5G equipment, which has a shorter range than previous generation mobile networks. In short, 5G networks must depend on many more base stations to provide overall coverage. That's why big Telecom companies are eager to support any venture that can lower their capital. 

What is Parallel wireless Open RAN?

Parallel Wireless Open RAN solves the triple challenge of interference, mobility, and distribution. These challenges are as follows:

  • That will improve overall system performance and frequency utilization.
  • Parallel Wireless coordinates directly with related miniature cells. It also sends all necessary signals to the macrocells and reduces the overall system control signaling. Apart from interference issues, congestion of cellular networks can affect the user experience due to increases in transmissions and associated signaling overheads.
  • Parallel Wireless Open RAN controller dynamically executes parameter changes to optimize user experience according to their mobility.
