All outdoor connectors or feeder cable connectors are
properly sealed to prevent water. Wrap the cable using
one-layer PVC insulation tape, three-layer waterproof tape,
and then three-layer PVC insulation tape. The tape shall be
attached evenly and neatly. The network cables shall be
covered with waterproof PG tubes.
Cable connectors are secured on cables and sealed to prevent
water intrusion. The outlets of cable conduits on a wall are
sealed by waterproof and flame-retardant materials. Drip
loops meeting the minimum bending radius requirement are
made on the network cable segment that stretches indoor.
Do not deploy cables overhead between two buildings.
Waterproof labels (providing device names and cable
directions) are filled and attached to signal cables correctly.
Each label is attached 20 mm to 100 mm from the
corresponding cable connector.
Surge protection measures are taken in the places where the
outdoor APs are installed. The outdoor APs, antennas, and
signal cables are deployed within 45-degree protection area
of a lightning rod.
The bare wires of network and feeder cables should be
covered by the winding pipes, flexible metal conduit, PVC
pipes, or galvanization pipes. The cable outlet and inlet are
sealed to prevent dusts.
The installation positions of antennas should comply with the
engineering design and antennas should be securely and
reliably installed.
There should be no obstacles in the major coverage direction
of antennas. The direction and downlink tilt of antennas
should be adjusted based on the coverage targets.
There should not be metal subjects within 1 m around an
outdoor omnidirectional antenna.
The azimuth deviation of a directional antenna should be
within 5 degrees and the tilt deviation within 0.5 degree.
The antennas are fixed using special support that supports
installation of surge protection devices and shall be located
within a 45 degree protection angle of a lightning rod. When
an antenna is mounted to a pole, the distance between the
antenna and top of the pole should be at least 30 cm.
Take waterproof measures on connectors of the antennas and
feeder cables and keep the drain holes of antennas
downwards.
