In a perfect world, it will be 10 to 20 feet. And this depends on two factors; 

  • The construction of the room. Metal wall studs shield outside interference more than wood stud walls, increasing the distance of the wireless connection.
  • The type of interference do you have within the room? Equipment that can cause EMI (electro-magnetic interference) will decrease the wireless range. 

It is always best to run a test before you need to use the Quick Keys or Pen Tablet in wireless mode to see what your limits are. 

Depending on how your office or classroom is set up, the range of the wireless connection for the Quick Keys or the Pen Tablet might be right at 10 ft or 3 m.

It is always best to explore where your boundaries are first.
