Viva ORAN…in Bulgaria!


Dutch-based United Group is working with US-based Parallel Wireless to trial Open Radio Access Network (ORAN) technology in Bulgaria on the Vivacom network.

Vivacom is a major MNO in Bulgaria and is one of eight countries in which United Group operates. Collectively the group services more than 15 million users and has nearly 15,000 employees.

The trial in Bulgaria is a combination of lab testing and field testing on Vivacom’s existing network and seeks to demonstrate successful implantation of ORAN networks in both urban and rural environments. The aim is to showcase that ORAN across 2G, 4G, and 5G can deliver equivalent or improved performance compared to traditional radio access networks (SRAN).

Vivacom CEO, Nikolay Andreev, flagged that “ORAN brings opportunities for greater vendor diversity and much-needed innovation in the mobile radio network sector,” and further commented “This technology will provide flexibility and competitiveness for operators, and improved services for customers. We hope this trial will be the first step in delivering ORAN technology to Bulgaria.”

Steve Papa, Founder & CEO of Parallel Wireless commented that “Bulgaria is a great place to showcase the benefits of ORAN demonstrating its flexibility and agility, allowing United Group & Vivacom the freedom to choose its vendors without being locked in with one specific vendor”

The Netherlands is not only HQ for United Group but is also the location of this years Total Telecom Congress. Join us for the Technology Congress on the 22 November for the panel discussion “Open RAN for network efficiency and better services”. Find out more at
