Its an underground train station that opened around June 2017. I guess it could be a MM or SC but in all my experiences DAS systems show up as MM on SCP. That how it is in JFK and LGA airport.
edit: its the west end concourse of penn station.
I'll have to check. My track got called right after that speed test so I didn't have time to test. Since its only 2xCA with 64QAM I almost hit max speed. which I think is around 238Mbps if I remember correctly
