What is the range of the LEGO Powered Up remote control system?
Your mileage may vary, but according to LEGO, the range is about 10m (33ft) in open air.


  The Bluetooth signal distance is usually around 10 meters/33 feet in an open area, but it can vary, depending on a few things: Low batteries in the remote control, and obstacles – concrete walls, for example – may decrease the signal distance. Try to remove obstacles, or find another place to play with your train, if it seems like the distance is shorter than expected.
