2.3 Identify room layout
2.3.1 Check coverage area
Real coverage area of conference room (usually coverage area of conference room is
smaller than the conference room area)
2.3.2 The relationship between ceiling height and infrared emitting and
receiving coverage area.
Note: The height mentioned about is the distance from ceiling to desk.
2.3.3 Check quantity of receiver unit
Please check the ceiling height and coverage area of one receiver unit with above
information (2.3.2), to make sure real coverage area can receive the signal well.
Calculate formula: (A: Receiver quantity, B: Real coverage area, C: Coverage area of one
receiver unit)
