3 Determining the Installation Position
Installation personnel need to manually record the MAC addresses and deployment positions of devices
for commissioning engineers to configure. For example, the location information can be recorded on the
package as a reference for changing the alias by scanning a bar code using WeFTTR app.
You can scan the QR code on the back of the device to obtain the quick start guide.
Generally, the device is installed on a wall or ceiling by using a mounting bracket. The
installation position is determined by the site survey. At least 200 mm clearance must be
reserved between the cable outlet of the device and the wall. Figure 3-1 shows the installation
clearance requirements.
Figure 3-1 Installation reference diagram
When determining the installation position, comply with the following rules:
Minimize the number of obstacles (such as walls) between the device and STAs.

The device can be installed on the ceiling (recommended, the ceiling height does not
exceed 5 m) or on a wall (about 3 m above the floor).
Keep the device away from electronic devices that may cause radio interference, such as
microwave ovens, APs, and antennas. For details, see Table 3-1.
The installation position should be as concealed as possible to avoid disturbing daily
work and life.
Install the device in a site that is free from leaking or dripping water, heavy dew, and
humidity, and take protective measures to prevent water from flowing into the device
along the cable.
Do not install the device in an environment with high temperature, dust, poisonous gases,
flammable or explosive objects, electromagnetic interference (from a radar station, radio
station, or substation), unstable voltage, violent shakes, or strong noise.
Table 3-1 General requirements for antenna anti-interference deployment distance
Scenario
Deployment Distance Requirement
Indoor
installation
scenario
Distance between antennas: > 7 m
Distance from 4G antennas of an operator: > 5 m
Far away from other electronic devices (such as microwave ovens)
that may cause antenna interference
For a device with a built-in antenna, the distance requirement for the antenna is the distance requirement
for the device.

The methods for ceiling-mounted and wall-mounted installations are the same.
Ceiling-mounted installation is recommended.
Select an installation mode based on the mounting bracket.
A wall for installing the device needs to meet the following requirements:
The wall can bear the weight of four times the total weight of the device and mounting bracket
without damage. When the total weight of the device and mounting brackets is less than 1.25 kg, the
load-bearing capability of the wall must be greater than or equal to 50 N.
When the tightening torque of a screw reaches 3.5 N·m, the screw still properly works, without
crack or damage on the wall.
Mounting brackets and expansion screws are required to install the device in ceiling-mounted
mode. The procedures are as follows:
When fixing the mounting bracket, ensure that the arrows of point upwards.
1. Attach the mounting bracket against the wall and adjust its position properly. Mark
positions of the mounting holes with a marker, as shown in the following figure.

without damage. When the total weight of the device and mounting bracket is less than 1.25
kg, the load-bearing capability of the T-rail must be greater than or equal to 50 N.
Materials required for installation: two steel wire ropes, used to secure the mounting
bracket to a T-rail.
Procedure
1. Attach the mounting bracket against the ceiling and adjust its position properly. Mark
positions of the mounting holes (group J) with a marker, as shown in the following
figure..
2. Use an electric drill to drill holes on the ceiling based on the marked positions. It is
recommended that the hole diameter be greater than or equal to 3 mml.
3. Lead the steel wire ropes through the group J holes on the mounting bracket and the
holes on the ceiling in sequence, tighten the ropes, and use a hex key to tighten the heads
of ropes. The mounting bracket is secured to the ceiling.
