No network coverage at an event? This is how mobile amplification for the mobile phone network works!
You're at a concert, in a stadium or in the middle of a festival, and just when you want to send a message or post a photo, nothing works. But there's a very simple problem behind this: the mobile network is overloaded.
Why the network reaches its limits at large events
Under normal conditions, the existing network capacity is easily sufficient. But when tens of thousands of people gather in a confined space and all want to go online at the same time, bottlenecks occur. The existing antennas can no longer process the enormous amount of data.
Mobile masts as a flexible solution
To ensure that you still have reception even in packed stadiums or at huge events, mobile transmission masts, known as Mobile Radio Trailers (MRTs), are used. These portable masts are set up especially for large events. The MRTs are installed on site and connected directly to the existing network. This selectively boosts mobile phone coverage. Once the event is over, they are simply dismantled again.
More than just for events
It's not just concerts and festivals that benefit from this technology. MRTs are also used in crisis situations, such as natural disasters, to maintain mobile phone coverage.
