1. Introduction
Congratulations on your purchase of a SkyWay-Mobile BTS system. This user’s guide
contains basic description of the system, basic installation and configuration steps to act as
a basic guideline for the end user. This guide is not to act as a step-by-step guide for self-
installation by end users.
This product requires a full professional installation services by Solectek’s field engineering
staff or authorized reseller officially certified by Solectek. The installation services will
include the following work:
Site survey and RF planning.
Drive test, mapping of the coverage area.
Physical mounting of the outdoor components on tower or rooftop
Antenna alignment
Configuration, calibration and troubleshooting
Commission of the service

2. Installation
Installation Cabinet
The SkyWay-Mobile BTS is typically installed in a standard 19 inch cabinet. The outer
dimensions are:
Height x Width x Depth – 1550 mm x 600 mm x 722 mm
The following is a diagram of the cabinet, as an example.
Fig 2-1: SkyWay-Mobile BTS cabinet
2.2 Position and Installation of Cabinet
Layout of Cabinet
It is recommended to position the BTS cabinet as shown in Figure 2-2 in accordance
with the following guidelines.
The spacing between the rear side of the cabinet and the wall should be at least
600mm.
In the front side of the cabinet, at least 600mm spacing should be reserved as a work
area.
Fig 2-2: Layout of the network facility and location of BTS cabinet
Place the cabinets based on the engineering design requirements and accurately mark
out the positions of the supports on the floor. Install the accessories for cabinet
installation, as shown in Figure 2-3. Drill vertical holes with the appropriate punch drill
and drill bit, and then install M12 expansion bolts.
Figure 2-3: Installation of cabinet accessories
Do not over tighten the expansion bolts so that the installation accessories can be easily
moved if necessary. Install the cabinet in the preset position, and then rotate the
accessories to move the U-shape opening on the corresponding round steel bar of the
cabinet support, as show in Figure 2-5.
Figure 2-4 Bottom of the cabinet
Position the cabinet, make it sit flat by using a level and then tighten the expansion bolts.
Check the insulation impedance with a meg-ohmmeter between the cabinet and the floor
and make sure that the value is greater than 5MΩ.
2.3 BTS Installation
The overall structure of the BTS is shown in Figure 2-5.
Open the cabinet door, adjust the partition positions, push the BTS into the sub-rack.
Record the model and Factory No. of the BTS and cable loss data for future references.
Keep this set of information at an easily accessible location.
Make sure that any empty slot in the BTS enclosure is filled in with a cover panel.

2.4 Connection of Ethernet Cable
The following diagram (Fig 2-7) shows the connections between the BTS and a network
switch. The data interface on the BTS is Ethernet with standard RJ-45 connector, as
shown below in Figure 2-7.
Figure 2-7 RJ-45 Ethernet Connector
Fabricate the Ethernet cable using the RJ-45 connectors shown in Fig 2-7. Connect one
end to the Ethernet port located on the bottom left side of the BTS front panel as shown
in Fig 2-8 and the other to a network switch or other transmission equipment.

2.5 Connect Power Cable
The BTS uses a DC+24V power supply. A +24V power source may be locally available
as part of telco closet facility. Solectek supplies either of the following power supply
options in case that the user needs to use a separate stand-alone power supply.
220/120 V AC to +24V DC power supply unit.
-48V DC to 24V DC power supply unit (in case -48V DC is available on site).
A stand-along power supply must be securely installed in the cabinet. An example of a
typical power supply is shown in Figure 2-9.
Fig 2-9: An example of a stand alone power supply to be installed in the cabinet
In case of an AC installation, first use a standard electrical cord to bring 120/220V AC to
the power supply’s AC input, connect the equipment’s DC output to the cabinet’s circuit
breaker and then the grounding to the cabinet’s pooling current bar.
WARNING: AC/DC equipment installation and use must strictly comply with the AC/DC
equipment instruction requirements, and reliable grounding must be finished through
grounding cable
Figure 2-10: BTS rear panel with BTS power cable connections shown.
Use flame retardant cables as base station power cables, press them out through Ф6
copper lug, and screw down on the base station power wire posts, as shown in Figure 2-
10.
Connect one end of the DC+24V power cable to the air switch at the cabinet’s bottom,
the red is connected to the positive pole, and the blue is connected to the negative pole.
Connect the other end to DC power cabinet’s output terminal correspondingly, the red is
connected to the positive pole (the working ground), and the blue is connected to the
negative pole. One end of the greenish yellow is connected to the pooling current bar of
the base station cabinet, and the other end is connected to the protection grounding bus
bar in the equipment room, as shown in Figure 2-11.
Figure 2-11: Power distribution board
Connect one end of the power cable to the power distribution board underneath the rear
of the cabinet, and the other end to base station power wire posts. Complete the
connection for the air switch and the power distribution board as shown in Figure 2-12.
Figure 2-13 Connection map of the power
Connect the power cables to the connection at the side of electric power distribution
cabinet and label the connection as well. Connect the grounding bus bar to grounding
cable via connection and tighten it with bolts. The carrier’s staff are required to
cooperate on the scene when connect power cable to power distribution cabinet,
connecting the cables after having cut designated branch switch. After connection, close
the branch switch (make sure to close the air switch firstly), then connect the black pen
of the multi-meter with voltage grade to air switch working grounding and the red pen to
