Arcades, bars, restaurants and other public locations are likely to have many different forms of interference. Basements are popular game rooms, but often are not wired as well for WiFi. As a good rule of thumb, if you phone has a bad connection, the Scorbitron is also likely to have some difficulty. That being said, the nature of Scorbitron traffic is very low bandwidth with low latency requirements, so it tends to have very robust connectivity to a properly configured network, even inside an old pinball machine.
