Prague, 18th June 2026 – Primoco UAV, in cooperation with T-Mobile Czech Republic, successfully deployed a unique solution for the temporary enhancement of mobile coverage in an area with limited infrastructure during the Běhej lesy race in the Brdy region. The deployment of two fully certified Primoco UAV unmanned aircraft at the same time also verified the principle of their seamless rotation, paving the way for future continuous 24/7 operation, for example in crisis situations or extraordinary events.
The project is part of Deutsche Telekom Group’s long-term development focused on the use of unmanned technologies to rapidly provide connectivity in locations where standard infrastructure is unavailable or insufficient.
During the race, T-Mobile used a micro mobile base station connected via satellite connectivity in the start and finish area. Two Primoco UAV aircraft operated above the race route itself from the airport in Písek. The deployment of the two aircraft made it possible to verify their seamless rotation under real-life conditions, including refuelling and the resumption of operations without interruption to the services provided.
The solution was deployed in the sparsely populated former military area of Brdy, where mobile coverage is available only along part of the race route. Thanks to the deployed technology, almost 1,900 participants in the event had stable mobile connectivity available. From an altitude of approximately 2.3 kilometres, it was possible to cover an area of up to 20 km² and achieve connection speeds of up to 100 Mbit/s in a 10 MHz channel.
“Providing connectivity from the air is one of the key development directions for our unmanned aircraft. Experience to date confirms that drones represent an exceptionally effective solution for the rapid restoration or enhancement of mobile signal. In addition to use at sports and cultural events, we also see significant potential in crisis situations and natural disasters, where reliable communication is essential. Last but not least, the full certification of our aircraft enables their deployment with virtually no restrictions, making us unique on the market,” says Ladislav Semetkovský, Chairman of the Board of Directors of Primoco UAV.
“Connectivity is a critical layer of resilience. Despite the continuous improvement of our network and the expansion of coverage in remote areas, there are still places where mobile signal does not reach. In Brdy, we again verified that drones with a micro mobile base station, can quickly supplement mobile coverage where standard infrastructure is either unavailable or insufficient. If needed, a similar alternative solution can be used to temporarily provide network coverage for a location very quickly, even in demanding conditions or during an extraordinary event,” adds Carlos Fernandes, Chief Technology Officer of T-Mobile Czech Republic and Slovak Telekom.
“The solution works by having the drone carry a complete mobile base station and connect to the main network via satellite. The higher the antenna, the larger the area that can be covered and the more stable the signal. The customer is then automatically connected to the best cell without any need to change anything on their mobile phone. Mobile services can therefore be temporarily launched even in locations where suitable fixed or microwave connectivity is lacking,” adds Jaroslav Holiš, Research & Trials Senior Manager at Deutsche Telekom.
For Primoco UAV, the project represents another important step in expanding the practical applications of unmanned aircraft. The successful verification of handover between two aircraft in operation confirms that the technology is ready, not only for temporary coverage of events in hard-to-reach locations, but also for future deployment in long-term continuous operation.
Previously, T-Mobile commercially deployed a drone during the Jizerská 50 race, where it provided mobile signal coverage for the race route in the Jizera Mountains over the complete day.
