Why open source is becoming a core asset in the telecom industry
Open source is playing an increasingly important role in the telecom industry. What once was seen mainly as a development method is now a key part of how telecom products, platforms, and networks are built, operated, and improved.

We are seeing a clear change in approach. MNOs and MVNOs are moving from simply using technology to becoming more involved in how that technology is created and improved. This is happening because of three main needs: more flexibility, better cost management, and faster service delivery.

Breaking free from proprietary constraints
Telecom systems are still dominated by closed, proprietary solutions. These often created limitations for innovation, with long upgrade cycles and high integration and operational costs. Open source introduces a different model: one where modular components can be adapted and improved with more agility.

This approach encourages collaboration not just with the bigger-named vendors, but with vendors of any size that are adhering to industry standards, and that commit to making their code available to customers to engage with the peace-of-mind that no artificial license will hinder their systems.

Enabling modern architectures
Open source has also been key in the shift to cloud-native and software-based architectures. Tools such as Kubernetes, are enabling telecom players to manage network functions as microservices, deploy updates continuously, and monitor systems in real time.

These practices—such as infrastructure as code, CI/CD pipelines, and container orchestration—are no longer limited to IT companies. They are becoming standard in telecom as well, helping the industry move towards more scalable, automated, and resilient infrastructures.

In mobile networks, for example, open source cores like Open5GS and Free5GC are being used to launch and test 4G/5G services with greater control and flexibility. These tools are especially useful for labs, small-scale deployments, and innovation environments.

A more transparent and collaborative model
Open source does not mean eliminating vendors. It means changing how products and services are built and supported. Telecom companies can still rely on professional support, while keeping the benefits of transparency and shared development.
