installation
If antennas are embedded into APs, the deployment distance requirements on the antennas are those on APs.
2.5 Installing the Device
Remove the protective film on the surface before installation to prevent electrostatic discharge.
2.5.1 Installing the Device on a Wall or Ceiling
Installing the device on a wall or ceiling requires expansion screws. The procedures are as
follows:
1.
Issue 01 (2016-09-30)
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 equipment
along the cable.
Place the AP far away from electronic devices that may produce radio interference, such
as microwave ovens, antennas, and other radio communication devices. For details, see
Table
2-2.
Install the device in hidden places and ensure that the device does not disturb daily work
and life of residents.
Make the engineering design by fully considering such factors as hydrology, geology,
earthquake, electric power, and traffic. The selected site should comply with the
environment design specifications of communications equipment.
Deployment Distance Requirement
l There should be at least a 7 m distance between antennas.
l The antennas should be placed at least 2 m from the 4G antennas of
the carrier.
l The antennas should be placed far away from electronic devices that
may produce interference, such as microwave ovens.
NOTE
NOTE
Determine the installation area on the wall or ceiling and use a marker to mark the
drilling positions (the distance between the two drilling positions should be 60 mm).
