Baicells BSC7261A249D Outdoor LTE TDD Base Station
INTRODUCTION
The Baicells mm W is an advanced outdoor millimeter wave integrated base
station (g NB), which is designed and developed based on Qualcomm 5G SoC
solution. This 49dBm EIRP g NB is low power consumption, subminiature and easy
to maintenance.
This product helps operators to enhance the coverage performance of 5G
networks effectively, improve the capacity of 5G networks and eliminate the
blind district, meanwhile it also can help to reduce the system power
consumption.

NOTE: Other accessories have been packed in the packing box.
Install GPS Antenna
Read the following GPS antenna installation requirements before installing it on the base station.
- No major blocking from buildings in the vicinity. Make sure the space atop is at least 45 degrees unblocked by any buildings.
- Avoid installing the GPS antenna in the vicinity of any other transmitting and receiving devices, to avoid interference.
- The GPS antenna should be installed within 45 degrees to the lightning rod.
The GPS antenna system is assembled in manufacturing before packing. The only installation step is to fix the GPS mounting bracket on the base station with the M4*14 screws.
NOTE : The base station may adopt different models of GPS antenna, so the GPS antenna may not the same as above figure. But the installation steps that fix it on the base station is the same.
Weatherproofing
To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following figure.
-
Insert the cable into the cold shrink tube.
-
Tighten the connector.
-
Push the cold shrink tube to the top joint, and pull out the strip.
-
Ensure the cold shrink tube is tightly fitted with the connection.
Pole Mounting
Check to ensure the diameter of the pole is in the range of 1.6 inches to 2.8 inches (40mm to 70 mm). The position of the g NB on the pole should be at least 47 inches (120 cm) in height.
The brackets have been pre-assembled in manufacturing before packing. It includes two parts, one is pre-assembled on the back of device. The other is for pole mounting or wall mounting, as shown in Figure 2-1.
Figure 2-1 Pre-assembled Device
Mounting Bracket on the Back of the g NB
Pole Mounting Bracket
Following will introduce how to fix the pre-assembled g NB on a pole.
-
Put the pole bracket against the pole.
NOTE the arrow must be upward. -
Assemble two omega clamps back and fasten four nuts on the back of the bracket.
-
Hung the g NB (with bracket)on the pole bracket Ensure the hook on the g NB bracket is stuck in the slot.
-
Fasten the screw on the top of the bracket using a cross screw driver.
After mounting, adjust the g NB to a proper angle by adjusting the adjustable bracket.
Wall Mounting
NOTE : The wall must bear at least 4 times the weight of the g NB.
Take apart assembly bracket first, only remains the wall bracket, as shown in Figure 2-2.
Figure 2-2 Wall Bracket
Following steps introduce how to fix the pre-assembled g NB on a wall.
-
Fit the installation bracket on the wall and mark drilling locations with a marker pen.
NOTE : the arrow must be upward .
-
Drill two holes at the marked locations and install expansion bolts.
And then hang the wall bracket on expansion bolts, and fasten with flat washers, spring washers and nuts.
-
From top to bottom, clip the g NB into the hook on the bracket and tighten the pin on the top of the bracket.
Connect Cables
Power ON
Power on the g NB, and wait a few minutes while the g NB boots up. Per the previous indicator description in “1 Appearance”, check that the LED indicators are lighting as expected.
