1. Introduction A compact, high output power, resilient CBRS (Citizens Broadband Radio Service) complied LTE Small Cell is presented in Fig1.1. The device is water and dustproof (IP65) and can be pole mounted, which makes it suitable to be deployed in a dense factory area, both indoors and outdoors. Figure 1.1 T99B226 overview The LTE CA technology deployed in this outdoor small cell is complied with specification defined by IEEE 3GPP Alliance.
2. HW installation guide and specifications This section describes HW overview of the Outdoor Small Cell-T99B226 Connectors and Interfaces As shown below in fig 2.1, T99B226 consists of four N-type cable connectors (LTE antenna #1,2,3,4) on the bottom side of the device for LTE antennas and an ethernet RJ45 port for power. There are four bolt holes on the back side of the device so that it can be pole mounted onto a factory pole by using a mounting bracket.
Cable routing and installation guide While installing, the device should have a clear view towards potential user transmitters 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.
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.

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. Figure 3. CBRS Network Topology 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.
Figure 4. T99B226 Configuration Overview 3.1.1 Basic Setting The Small Cell contains one 10/100mbps Ethernet interfaces. The factory default setting is WAN. The Ethernet port should be configured according to the actual requirements when used for the first time. Click “One Page Settings” -> “Basic Settings” to enter the gateway network configuration, including WAN Configuration and HeMS Configuration.
Figure 5. Basic Configuration Setting Small Cell will lack the ability to communicate with configuration/fault management portion the EPC and must rely on you to manually configuring the device. 1) Ensure that you have reserved a static IP inside of the network with IT and installed all the necessary software for EPC. 2) Point the Small Cell to the established IP of the EPC. Example IP: 192.168.1.222:8080/femsacs/acs 3.1.

Small Cell radiation overlap cells within in rage of each other to the same frequency as this will cause interference as shown in figure. 6) UL_EARFCN_List – Specify the uplink Radio Frequency Channel Number for two RF card. 7) ULDLMode – Indicates the TDD subframe configuration. The supported values are mode 1 and 2. Specify value 1 will obtain higher uplink bandwidth and lower downbandwidth. 3.1.2.
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.
2) [ENB] veMmeReadyGet: primary ePC not ready: EPC needs to be restarted or shareRan configuration is incorrect (see section 3.3.3) 3.4 Alarm As shown in the figure below, the small cell raises an alarm when there is an internal problem that interferes with the small cell being able to complete its normal function. The small cell will indicate there is an issued by flashing a red waring light where the LED is labeled status. 1.
4. Warranty and compliance The T99B226 Small Cell comes with a 5-year limited hardware warranty. • ITU 3GPP: 3GPP E-UTLA Release 9 • • IEEE IEEE 802.3u 100Base Ethernet IEEE 802.
