1 Product Overview
About This Chapter
The R250D in Huawei Agile Distributed Wi-Fi Solution is applicable to scenarios with high-
density rooms and complex wall structures, such as schools, hotels, hospitals, and office
meeting rooms. Huawei R250D uses an 86 mm plate in compliance with international
standards and can be easily installed into an 86–type box in a room. It is equipped with a
built-in antenna and a hidden indicator; therefore, installation of the R250D does not affect
indoor decorations or designs. It also has an IEEE 802.11a/b/g/n/ac/ac Wave 2 wireless
module and can work on both 5 GHz and 2.4 GHz frequency bands. It supports PoE power
supply, and can be directly connected to a central AP and deployed in a room. The central AP
and the R250D are connected through network cables, which greatly extends the coverage
range, enhances flexibility in AP deployment and planning, and reduces the engineering
construction costs.

2.3 Unpacking the Equipment
Before unpacking the carton, ensure that the packing carton is intact and not damaged or
soaked. Stop unpacking if the equipment is rusted or soggy. Then, investigate causes and
contact the supplier.
After unpacking, check items in the carton against the packing list. If any item is missing,
contact the supplier or agent.
Usually, the packing list contains the following items.
lRemote Unit
lExpansion screws
lScrew
lQuick start guide
lWarranty card
lMAC address label
lSN label
2.4 Determining the Installation Position
lDo not deploy the device in places with high temperature, dust, noxious gas, unstable
voltage, much vibrations, or strong noise, or in places near flammable or explosive
materials and interference sources such as a large radar station, radio station, and
transformer station.

lInstall 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.
lPlace 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.
lInstall the device in hidden places and ensure that the device does not disturb daily work
and life of residents.
lMake 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.
Table 2-2 General anti-interference requirements
Scenario Deployment Distance Requirement
Indoor
installation
lThere should be at least a 7 m distance between antennas.
lThe antennas should be placed at least 2 m from the 4G antennas of
the carrier.
lThe antennas should be placed far away from electronic devices that
may produce interference, such as microwave ovens.
NOTE
If antennas are embedded into APs, the deployment distance requirements on the antennas are those on APs.
2.5 Installing the Device
NOTE
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. 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).
