Success Case
Milan Underground Metropolitana L5: A new metro line granting full mobile coverage for travelers
Transport and logistics
Challenges
Underground stations and entire metro lines have always been areas difficult to reach with continuous, seamless connectivity. This could be due to capacity (busier times can saturate the network at peak hours due to the density of users with high data volumes) or due to coverage (the sheer length of these underground lines can also be afecting performance by resulting in costly solutions).
Solution
In total we have deployed a SISO solution with 508 antennas and 53 RUs all throughout the area. The DAS solution includes an extender, or remote access facility, a system designed to extend mobile telephone services within specific places. To this end, the system not only extends coverage but also performs network functions, providing radio coverage inside the metro as agreed with the operators.
