Cable routing and installation guide
Whileinstalling, thedeviceshouldhaveaclearview towardspotentialusertransmitters and
not obstructed by nearby trees or buildings. Once you pick an ideal installation spot, place the
mast bracket and wrap it around the mast, clamp the bracket and device together by tightening
screws through bolt holes on the back of device and the bracket.
LTE antenna wires need to be pulled from the N-Type connectors on device along four
bracket arms to four antennas on each corner as shown in figure2.2 and the running wires can
be fixed onto bracket arms using bracket ties. It is the best practice to keep antenna rods
perpendicular to bracket branches and make sure four antennas are evenly distributed in four
corners.

Moreover, the GPS antenna needs to be positioned at a place where GPS reception is solid,
and the wire connecting GPS antenna to the device needs to be attached to the pole to ensure the
stability of the connection during non-ideal weather conditions. Power for T99B226 is
provided by connecting the power to a POE (power on Ethernet) adapter and through the
waterproof ethernet cable to the ethernet port next to the antenna ports as shown in fig2.3. For
the same reasons, the wires need to be attached to the pole firmly and the waterproof ethernet
port is complied with IP65 regulations which makes it resilient to outdoors conditions.

3.Private Network Solution
This outdoor unit (ODU) T99B226 receives data from user equipment (UE), then relay it to a backend
server (EPC) and routed to an application server for information processing.
3.1 Configuration Overview
Users can configure Small Cell parameters through the local Ethernet port of the Small Cell. Please
use a computer with a browser installed to configure the gateway. It is recommended to use Google
chrome or Firefox browser for Small Cell configuration management to obtain the best display
experience. Please connect the Ethernet port of the computer with a network cable, the length should
not exceed 100m, the network cable too long may cause the communication between the computer
and the gateway abnormal.
The factory default login address of the Small Cell management page is https://192.168.168.157.
Please set your computer under subnet 192.168.168.0/24 to access the webpage. If the configuration
page cannot be accessed normally, please contact your computer network administrator to check the
IP address of your computer. If you still cannot open the management page correctly, please contact

3.1.2.3 Gateway Configuration
The Small Cell needs to be in constant contact with the EPC via an inform method. This inform
method carries with it connection information, configuration options and general Small Cell data.
When the small cell needs to make a configuration change or status check the small cell need to
update the EPC. When the Small Cell needs to check in with the EPC the Small Cell checks the
ShareRan configuration option to find the address.
1) IPAddress: The Gateway IP address is to set to the static IP of the EPC. Ex: 192.168.1.222
2) PLMNList: Public land Mobile Network is used by the User Equipment (UE) to select which
small cell it will connect with.
3.2 Sniffer
