Bluetooth ranges are measured for antennas at two heights.
• 1.52 meters or 5 feet, the typical height of thermostat in the USA.
• Low Multiple Path Interference (LMPI) or 60% Fresnel zone clearance.

*There are 2 models of dipole antenna selling with BC833E: ANT060 for FCC/IC，ANT020 for CE use.
* Estimated, assuming BC833E passing FCC/CE certifications with the same antenna as BT840E/BC840E.
Deployment Recommendations
• To have the best Bluetooth data reception, direct line of sight between 2 devices should be away from
ground or wall.
• If one device must be installed closer to ground or a wall, install other devices far away from a wall or
ground.
• Indoor condition is different for different building. We suggest testing Bluetooth data reception in the
building with the worst case condition.
