The challenged faced with this venue was the large crowd that can gather at the stadium. During Sports Events and Concerts, the high number of mobile devices trying to connect to the MNO’s network congest the nearby Macros, making it extremely difficult to have data connectivity or even phone calls.
In order to address this challenge, the collaboration between Cellnex in Spain and CommsCon in Italy was key. The design was made according to the architectural needs of the stadium and can be differentiated in three parts: seats, indoor and outdoor, all implemented with a DAS system. The core of the system is the technical room, where is present the master unit which process and distributed MNO’ flow.
From there 10km of optical fiber transports the signals to the active devices (the remote units), which connected to the antennas radiate the signals. There are more than 200 antennas installed throughout the stadium with more than 100 remote units.
