The Importance of Open Interfaces

---

Open RAN is based on using open, standard interfaces. Unlike traditional networks that rely on one vendor, this new approach allows for more flexibility, innovation, and competition in building mobile networks.

In traditional mobile networks, all the parts such as the radio, processing units, and core network usually come from one company. These parts often use private or proprietary connections, which means the mobile provider becomes locked into using a single vendor. This limits flexibility, slows down innovation, and can increase costs.

Open RAN solves this problem by using open and standardized interfaces. This allows different parts of the network to come from different companies. For example, a provider could use a Radio Unit from one vendor, a Distributed Unit from another, and a Central Unit from a third. This ability to mix and match components encourages more competition and innovation.

To make this possible, Open RAN follows detailed technical guidelines that explain how each part should communicate. These open interfaces are the foundation of Open RAN and are key to creating a more flexible, diverse, and cost-effective mobile network.

Keep in mind: interfaces = connection

Two of the most critical interfaces in the Open RAN architecture are the Fronthaul and the Midhaul:

Open RAN uses standardized interfaces that let parts from different vendors work together. This changes the game in a few key ways:

• No need to rely on one company for everything
• Mix and match best tech from different sources

• Open standards make it easier for smaller players to join the market
• Competition drives better, cheaper, faster solutions

• More choices mean lower prices
• Easier upgrades and automation save on day-to-day operations

• Encourages open-source and academic collaboration
• Helps the whole telecom world grow together

• Open RAN works well with virtual networks and cloud setups
• Supports flexible, scalable, automated networks
