    Multiple paths to the same device is one of the ways MIMO allows for faster WiFi. If the WiFi setup has been tweaked for the environment, this doesn’t need to be a problem.

    Google suggesting using phones as hotspots makes the interference suggestion more unlikely, I think. I suspect they just haven’t done a good job at setting up their access points, which can be a challenge for large buildings (but shouldn’t be a problem for a company like Google with their own in-house WiFi engineers).

    Then again, this being Google, the team that designed the WiFi setup was probably shut down a month after they finished installing hardware and before they could make the software usable.

      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.
