I would think the metal parts of roof might be reflecting signals all around the building, which would cause interference between devices. (there is a limited number of WiFi channels), it might work better with a plastic roof, or one with RF absorbers.
Also, hundreds of mobile hotspots will impact the performance of all nearby wireless networks.
I wonder if Google actually has WiFi engineers. It’s not something you need to set up everyday. Still they have the money to hire a company that specialises in WiFi.
I don’t think the roof would be good at reflecting signals back at the device, it scatters them all throughout the building, rasing the noise floor.
In a way, phone hotspots can cause less interference then a proper access point because they use a lower transmit power, and allow the other devices to reduce power.
