1.Overview
AIO Small cells are low-powered cellular radio access nodes used to increase network
coverage and network capacity in indoor and outdoor wireless communications. This small
cell includes both 5G mmWave and LTE capabilities. It provides high speed data transfer
rates and increased mobility. The AIO small cell can be used to provide both 5G services and
a 4G network. It can be deployed in a commercial network or used in a private network to
service an enterprise.

2.Quick Setup
Once connected to a power adapter with 48DVC and a 10G Ethernet cable, and the
ethernet link to internet CBSD server and ePC via switch or router and CBSD was for
CBRS LTE function use, and it’s ready to go. The IP addresses are dynamically obtained
through internal DHCP and check the RF LED for service on.
The AIO smallcell support the management system with TR069 for LTE function,
NetCONF/Yang for NR system. It is easy to connect to FNMS (Fii Network Management
System). And it is easy to use the FNMS to control the AIO smallcell with CM/FM/PM and
upgrade firmware.
3.Installation guide
This chapter briefly describes all the steps for the installation of the small cell in terms
of both hardware and software. The small cell shown here is pole mounted.

3.1 Hardware installation
The small cell can be installed on a pole using a pole mount bracket as shown in Figure 3.2.

Figure 3.2 Pole mounting bracket accessories
•The pole mounting bracket kit consists of a pole mount plate, antenna back plate, pole
clamp plate, hex nuts and hex bolts.
•Step 1: Start by fastening the antenna back plate (A) of the bracket to the back of the
small cell using the Hex nuts (B). This is first done at the top.
•Step 2: Place the bracket firmly on the desired position/height on the pole.
•Step 3: Insert the Hex bolt (F) in the pole mount plate (C). Choose the nut and bracket
based on the size of the pole.
•Step 4: Now place the pole clamp plate (D) firmly behind the pole, align the holes with
the Hex bolt (F) and fasten the hex nuts (E).
•Step 5: First mount the top bracket on to the pole and then repeat the same procedure to
attach the bottom bracket.
•Step 6: The mount can be rotated manually in the vertical plane to point the small cell in
the desired direction as indicated in figure 3.3.

•Tighten all the nuts and confirm that the pole used for mounting is sturdy to hold the
weight.

Figure 3.4 (a) Figure 3.4 (b)
Figure 3.4 – Bracket flexibility
The pole mount bracket is very flexible to allow a complete 360 rotation of the mounted
small cell in the horizontal plane. This allows the small cell to be installed pointing in any
direction required. The bracket is also capable of a 90 rotation in the vertical plane. This means
the small cell can be pointed towards the ground or towards the roof as required.
The small cell can be rotated by 90 from the pole in vertical direction by manual rotation as
shown in Figure 3.4 (a). To rotate the small cell in the horizontal plane, loosen the hex nuts and
then rotate to the desired direction as shown in Figure 3.4(b). Fasten the hex nuts tightly.
