Down-tilt Angle
When installation height is more than 30 feet (10 meters), an antenna down-tilt angle is
required.
According to the above formula, the following tilt angles are highly recommended:
•
At a height of 10-30 feet (3-10 meters), no tilting is needed
•
At a height of 30-60 feet (10-20 meters), 5°-10° tilt is required
•
At a height of more than 60 feet (20 meters), please calculate the inclination angle
according to the formula provided above
3.2.
E1000 and S2000
The optimal placement for the Cassia E1000 and S2000 should be located above ground
at a height of 10 to 15 feet (3-5 meters), in direct line of sight of the Bluetooth Low
Energy device, and within 180 to 1000 feet (60-300 meters) range of the device. Ceiling
installations should be 6 feet (2 meters) away from nearby walls or columns. Obstacles,
like walls, as well as Wi-Fi interference, will reduce the range of Cassia’s Bluetooth
gateways.
Deployment principles:
•
Keep at least 3 feet (1 meter) away from cellular antennas and Wi-Fi access points.
•
Installation should be far from microwaves, wireless keyboard/mouse, and other
devices that also use the 2.4 GHz band.
•
Avoid installations near air conditioners, heating pipes, water supply pipes,
transformer boxes, an elevator operation room, etc.
