Bringing Connectivity to Underground Rail Network

It's always been a challenge to bring mobile connectivity to commuters in the underground rail network. The same challenges extend to mines and other facilities under the ground. One solution that has been widely adopted is the use of leaky feeders as antennas.

This solution is also used to compliment the existing terrestrial network in case of tunnels. We made a small tutorial looking at this from metro point of view but the same solution is applicable in many different scenarios.

5G presents a small challenge for this as it is tricky to go beyond 4T4R easily. Each T/R requires a leaky feeder which makes it expensive as well as challenging in other scenarios.
