Overview 1.1 Introduction The Baicells Nova452 is an advanced two-carrier outdoor eNodeB (eNB) compliant with 3GPP LTE TDD and hardware-ready for NR 5G technology. This 4x40W eNB operates in either Carrier Aggregation (CA) mode or Dual Carrier
(DC) mode. In CA mode, Nova452 supports 2CC (2 component carriers) DL/UL CA. 2CC DL/UL CA doubles DL/UL peak throughput comparing to that of a single carrier. By aggregating 2 separated spectrum resources into a virtual contiguous spectrum resource. In DC mode, each carrier is treated as an independent cell, supporting 512+512 users with each cell supporting 5, 10, 15 , 20 or 100MHz(only for NR) bandwidth. Using a Nova452 in DC mode simplifies and streamlines the deployment of split sectors. In addition, HaloB (an embedded EPC option) is available on the Nova452 as part of the base software. The Baicells patented HaloB solution migrates the necessary core network functions to the eNB. The product is easy to deploy and flexible to configure, which satisfies the outdoor wireless network capacity and coverage requirements well. It can be widely used in telecom operators, broadband operators, enterprises and other scenarios. 1.2 Highlights Standard LTE TDD Bands 40, 41, 42 GUI-based local and remote Web management Excellent Non-Line-of-Sight (NLOS) coverage Suitable for private and public deployments; any IP based backhaul can be used, including public transmission protected by Internet Protocol Security (IPsec) Peak rate: Up to DL 440Mbps with 4x4 MIMO Carrier Aggregation (CA) mode and UL 70Mbps with CA mode Supports 512 RRC connected users per cell, 512+512 RRC connected users in DC mode Supports downlink of 256QAM 1 Integrated small cell form factor for quick and easy installation Configured out-of-the-box to work with Baicells Cloud Core HaloB as embedded EPC solution Plug-and-play with Self-Organizing Network (SON) capabilities Inter operation with all standard LTE Evolved Packet Core (EPC) Highly secured with equipment certification against potential intrusion risk Supports TR-069 network management interface Lower power consumption, which reduces OPEX, can be powered easily by Baicells compact outdoor smart UPS 1.3 Appearance The appearance of Nova452 is shown in Figure 1-1.

Level bar Marking pen Knife Vise Wrench Percussion drill and some drill heads hammer Cross screw driver Cable vice Tape measure 5mm L-shape allen wrench T7 screwdriver head Ladder compass fixed pulley multimeter 2.3 Construction Safety 1. The installation personnel must master the basic safe operation knowledge, through the training, and having the corresponding qualifications. 2. Before installation, the installation personnel must be prepared with safety protection, 11 such as: safety helmet, safety belt, reflective clothing, gloves, and safety shoes, etc. 3. Before installation, the installation personnel must cross-check each other to ensure above preparations have done. 2.4 Installation Environment 2.4.1 Location Requirements 1. Avoid locations of warehouses and gas stations with flammable and explosive, and locations that fire and explosion are easy to happen during production. Do not install eNBs near dangerous industries and enterprises. Stay away from high voltage lines and railroads. 2. Under the premise of not affecting the layout of the eNB, the existing telecommunications building, post and telecommunication office or microwave station should be chosen as the site as far as possible. The existing machine room, power supply and tower facilities should be used sufficiently. 3. Avoid to install near high-power wireless transmitter stations, such as radar stations, television stations, etc. If the eNB must be installed in such locations, you should check whether there is mutual interference, and take measures to prevent it. 4. Avoid to install on mountains. The mountain interference range is large, therefor the frequency reuse will be affected. Install eNB on high mountains in rural areas is 12 often not good for the coverage of towns and villages in small basins. 5. Avoid to install in the forest. If the eNB must be installed in such locations, the height of the eNB must be higher than the treetop. 6. 7. It is strictly prohibited to install the eNB in the mining area and places where is easy to be submerged by flood and landslide In urban area, for the macro eNB, the site should be selected that is higher than the average height of buildings but lower than the highest building. For the micro eNB, the site should be selected that is lower than the average height of buildings and the surrounding buildings are well shielded. 8. In urban area, the eNB should avoid obstructions caused by tall buildings near the front of the antenna or the reflection interferes the same frequency eNBs behind it. 9. Avoid selecting sites where new buildings may affect coverage or there are co-frequency interference. 10. As far as possible, the site of eNBs of the two communication network systems should be co-located or close. 2.4.2 Environmental Requirements Table 2-2 provides typical environmental specifications for this eNB. Table 2-2 Environmental Requirements Item Temperature Relative humidity

The yellow-green ground wire must be at least 10mm2 in diameter. In principle, always place the grounding as near as possible to the equipment. Connect to a reliable outdoor grounding point (earth) using one ground screw. The connection of the grounding points and ground bar need to be tight and reliable. Rustproofing the terminals, e.g., with anti-oxidant coating or grease, is required. 2.6 Weatherproofing To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following (Figure 2-1). 1. Insert the cable into the cold shrink tube. 2. Tighten the connector. 3. Push the cold shrink tube to the top joint, and pull out the strip. 4. Ensure the cold shrink tube is tightly fitted with the connection. Figure 2-1 Weatherproofing 14 3. Installation 3.1 Unpacking Before opening the box, make sure the package is in good condition, undamaged and not wet. During the unpacking, avoid potential damaging impacts from hits or excessive force. Once unpacked, check whether the quantity is consistent with the packing list. 3.2 Installation Procedure Figure 3-1 provides an overview of the installation process. Figure 3-1 Installation Process 3.3 Install GPS Antenna Read the following GPS antenna installation requirements before installing it on the eNB, as shown in Figure 3-2. 15 Figure 3-2 GPS Installation Requirements No major blocking from buildings in the vicinity. Keep the rooftop buildings a distance away from the GPS. Make sure the space atop within 90 degrees (at least 45 degrees) is not blocked by any buildings. Avoid installing the GPS in the vicinity of any other transmitting and receiving devices. Avoid interference from other transmitting antennas to the GPS antennas. The GPS antenna should be installed within 45 degrees to the lightning rod. When two or more GPS antennas are installed, it is recommended to keep the spacing of more than 2 meters and install multiple GPS antennas in different locations to prevent simultaneous interference. Do not install the GPS antenna near other transmitting and receiving equipment. Do not install it under the microwave antenna or high voltage cable. Avoid the direction of radiation from other transmitting antennas to the GPS antenna GPS antenna feeders cannot be grounded together with ground conductors of interfering equipment such as air conditioners, motors, and pump motors, etc. to prevent external interference from being introduced into the antenna system. The GPS antenna system is assembled in manufacturing before packing. The only installation step is to fix the GPS mounting bracket on the eNB with the M4*14 screws
(Figure 3-3). Figure 3-3 GPS Antenna Installation 16 NOTE: The eNB 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 eNB is the same. 3.4 Install on Pole Check to ensure the diameter of the pole is in the range of 1.6 inches to 3.9 inches
(40mm to 100mm). The position of the eNB on the pole should be at least 47 inches
(120cm) in height, as shown in Figure 3-4. Figure 3-4 Installation Height The brackets have been pre-assembled in manufacturing before packing. It includes two parts, one is pre-assembled on the back of the device. The other is for pole mounting or wall mounting, as shown in Figure 3-5. Figure 3-5 Pre-assembled Device 17 Following will introduce how to fix the pre-assembled eNB on a pole. 1. Take apart two clamps from the assembled bracket. 2. Put the bracket against the pole and assemble two clamps back, note that the sequence of flat washers, spring washers and nuts keep the same with original. 3. Fasten the pole bracket to ensure the bracket is firmly fixed on the pole. 4. Hang the eNB (with bracket) on the pole bracket. Ensure the screw on the bottom of the bracket clip into the groove on the pole bracket, and then fasten the screw. 18 5. The installation is complete, and proceed to 3.6 Connect Cable. 3.5 Install on Wall Take apart assembly bracket first, only remains the wall bracket, as shown in Figure 3-6. Figure 3-6 Wall Bracket Following will introduce how to fix the pre-assembled eNB on a wall. 1. Put the wall bracket against the wall and mark two drilling locations with a marker pen. Caution that the groove of bracket is at the bottom. 2. Drill two holes at the marked locations and install expansion bolts. 19 3. Hang the wall bracket on expansion bolts, and fasten with flat washers, spring washers and nuts. 4. Refer pole mount step to hang the eNB on the wall bracket. 20 5. The installation is complete, and proceed to 3.6 Connect Cable. 3.6 Connect Cables 3.6.1 Cable Laying Requirements General requirements:
Bending radius of feeder cable: 7/8 > 250mm, 4/5 > 380mm. Bending radius of jumper cable: 1/4 > 35mm, 1/2 (super soft) > 50mm, 1/2
(ordinary) > 127mm. Bending radius of power cable and grounding cable: > tripled of the diameter of the cable. The minimum bend radius of the optical fiber is the 20 times the diameter of the optical fiber. Bind the cables according the type of the cable, intertwining and crossing are forbidden. An identification label should be attached after the cable is laid. Optical fiber laying requirements:
Avoid circling and twisting during the laying. Avoid binding on a turn. 21 Avoid pulling and weighing down the optical fiber. The redundant optical fiber must enwind the dedicated device. Grounding laying requirements:
The grounding cable must connect to the grounding point. The grounding cable must be separate with the signal cables, of enough distance to avoid signal interference. 3.6.2 Connect GPS Antenna Cable The top of the GPS antenna should avoid the frontal position of the directional antenna as far as possible. In the case of obstruction, it is recommended to pull away and install the GPS antenna, that is, the GPS antenna be installed in an open and lightning protected position. 1. Insert the GPS jumper into a cold shrink tube. 2. Connect one end of the GPS jumper to the GPS antenna. 3. Push the cold shrink tube to the top joint, and pull out the strip. 4. Take another cold shrink tube, and pass through the GPS jumper. 5. Connect the other end of the GPS jumper to GPS interface on the eNB, which also need weatherproof protection. 3.6.3 Connect RF Cables CAUTION:
It is strictly prohibited to activate the cell and transmit RF if the antenna feed system is not connected properly. The wireless signal transmission power of the outdoor eNBs is large, if the eNB transmits without the antenna feed system, which may cause injury to the body of the construction personnel and the damage of RF power amplifier devices. 1. Take off dust caps of the ANT0 to ANT3 interfaces. NOTE: The Nova452 can connect four antennas, the interface number is from ANT0 to ANT3. 2. Insert RF cables into cold shrink tubes. 3. Connect RF cables to the ANT0 to ANT3 interfaces on the eNB, and tighten them with wrench. 4. Push the cold shrink tube to the top joint and pull out the strip. 22 5. Connect the other end of the RF cables to the external antenna. NOTE: The external antenna side interface at the other end of the feeder also needs waterproof treatment. Baicells does not provide the waterproof materials for this part, so customers need to prepare and carry out waterproof operation by themselves. NOTE: The RF antenna end also needs waterproof protection. 3.6.4 Connect Optical Fiber Cable The optical interface is located in the eNBs wiring cavity. First, you should unscrew screws on the cover of the eNBs wiring cavity and open the wiring cavity. 1. Connect the optical fiber to OPT0 interface in the wiring cavity. NOTE: At present, only OPT0 interface is used. 2. Lay the optical fiber along the wire groove, and stretch out the wiring cavity from OPT0 hole. The redundant optical fiber should enwind neatly. 3.6.5 Connect Power Cable Since the length of cable needed for power varies from site to site, the two ends of the power adaptor are bare terminal ends. You will need to make the power cable according to the actual measurements of the installation site, and assemble the power plug and power terminal on the two ends of the power adaptor. Strip .47in/12mm insulating layer with a wire stripper. The power cord length should be kept below 330 ft/100m. The connection steps for the power cable are as follows. 1. Assemble the power plug. The power plug will be installed on the end of the input direction. Refer to the labels on the power plug for connecting the live wire, neutral wire, and ground wire to the corresponding terminals separately, and tighten the screws. 2. Assemble the power terminal. The power terminal will be installed on the end of the output direction. Refer to Figure 3-7 to connect the live wire and neutral wire. Figure 3-7 Power Terminal 23 Before connecting the live and neutral cables, arrange the live and neutral cables separately using VE6012 terminals as shown in Figure 3-8. The brown terminal is used for the positive terminal (+), and the blue terminal is used for the negative terminal (-). Figure 3-8 Crimping Cables 3. Connect the power cable to the PWR interface in the wiring cavity. 4. The power cable lays along the lint slot, and stretch out the wiring cavity from the PWR hole. 5.
(Optional) The input of the power adaptor connects to the outlet. If the outlet is indoors, place the power adaptor indoors. If the outlet is outdoors, place the power adaptor in a waterproof box. 6. After the cable connection is complete in the wiring cavity, tighten the screws on the cover to close the wiring cavity using M4 cross screwdriver. 3.6.6 Connect Ground Cable 3.6.6.1 Pole Grounding The purpose of the pole grounding is to protect the equipment in the station from the damage of lightning overvoltage as far as possible. However, the interfaces between the eNB and the outside world mainly include power system, grounding system, antenna feeder and lightning receiving device, and signal line. Therefore, the damage caused by lightning mainly comes from the voltage difference between the equipment in the eNB and one or more of the four interfaces. The pole grounding is shown in Figure 3-9. 24 Figure 3-9 Pole Grounding 1. The installation position of the grounding bar shall meet the design requirements. The holding pole and tower body must be connected to the lightning protection network or grounded with a separate lead. 2. The diameter of the grounding wire meets the design requirements. The copper nose must be used for grounding, and the grounding resistance is required to be less than 10 ohms. If the resistance of the public network communication equipment placed in other systems is less than 10 ohms, the grounding network of the system should be overlapped. 3. The grounding wire must be the whole wire material. When laying, it should be bound separately with other cables. All grounding wires should be fixed with wire code or binding tape with a fixed spacing of 0.3m. The appearance should be straight and beautiful. 4. The copper bar must be used for the grounding bar, and the specification of the grounding bar shall meet the design requirements. If there are no specific requirements in the design, 300 40 4mm and fixed with expansion bolts. 5. The grounding wire must be made of the whole cable material, the intermediate joint is strictly prohibited, and the excess length should be cut. The skin shall be complete, and the insulation resistance of the core wire to the ground (or metal isolation layer) shall meet the technical requirements of the cable. 6. The grounding wire shall be connected to the integrated grounding bar of the building. If it is impossible to connect to the integrated grounding bar of the building, the appropriate grounding point can be selected according to the integrated grounding situation of the indoor building. The selection of grounding point must be higher than the grounding grid, and the feeder grounding shall be towards the 25 downward direction of the feeder, never upward. 7. The grounding electrode of the self-built grounding grid for the outdoor antenna of the tunnel must meet the design requirements. The buried depth of the grounding electrode and the welding quality of the flat iron meet the specification requirements. In principle, the buried depth of the grounding electrode shall not be less than 0.7m. The non-self-built grounding network shall be connected to the grounding network of the owner. 8. The eNB grounding, power adapter grounding, distribution box grounding and feeder grounding must be connected to the grounding bar independently, and the grounding bar must have a path from the lead to the earth. 3.6.6.2 eNB Grounding Prepare the grounding cable according to the actual measurements and requirements of the specific installation site. The Nova452 has two grounding screws located on the bottom of the unit (Figure 3-10). Follow the steps below the figure to connect the ground cable. Figure 3-10 Grounding Screws 1. Unscrew one grounding screw, connect one end of the ground cable to the grounding screw, and fasten it again. 2. Repeat step 1 for the second grounding screw. 3. Once the eNB is installed at the outdoor location, the other end of the ground cable needs to connect to a good grounding point. 3.6.6.3 GPS Antenna Grounding If the length of GPS antenna is more than 5 meters, it is recommended to extend the 26 installation distance. It is suggested to carry out lightning protection of GPS antenna, add lightning protector, and connect the lightning protector to the grounding bar, as shown in Figure 3-11. Figure 3-11 GPS Grounding 3.6.6.4 (Optional) Power Adapter Grounding The adapter ground terminal is connected to the ground bar conforming to the local standard through the ground wire, as shown in Figure 3-12. Figure 3-12 Power Adapter Grounding 3.7 Maintenance Chamber Waterproofing When all the installation has been completed, it is necessary to close the maintenance chamber of the equipment and fasten screws to play the role of waterproof at the same time. 1. Clamp the power cord to the wire position and seal the wire diameter 9 1mm. 2. Put the pigtail / network cable on the wire, and seal the wire diameter 7 1mm. 3.8 Power on to Check LED Status Power on the eNB, and wait a few minutes while the eNB boots up. Per the previous 27 Table 1-2 in 1.3 Appearance, check that the LED indicators are lighting as expected. 28 4. Attentions 4.1 FAQ 1. After the device is connected with the power line, the PWR of the device will not be displayed when it is powered on. 1 Maybe the power line is not connected well, and the contact is poor. 2 There is no power in the circuit. 3 Reverse connection of DC wire. 4 The adapter does not work. 5 Poor contact of equipment power interface. 2. How to connect the antenna feeder 1) ANT0 is the main channel and ANT1 is the secondary channel. 3. GPS has been out of sync 1) The antenna is not installed in an open place. 2) The antenna is blocked, which affects the search. 3) There are strong interference sources around the installation location, such as large transformer station and high-power motor fan. 4) Installed under the front cover of wireless antenna, strong signal interference and so on. 5) GPS satellite search is slow and takes a long time. The number of satellites and signal strength can be observed in the maintenance page. 4. How to choose the position of holding pole in the roof 1) Not near the edge. 2) The position of non-bearing beam cannot be selected. 3) Do not choose the side close to the barrier, you need to choose the most open position. 5. The coverage of eNB signal is not ideal after opening 1) Check if the power is full in the base station configuration. 2) Check whether the equipment has standing wave alarm. If there is any alarm, please handle it in time. 29 3) Check whether the RF frequency band of the equipment is consistent with that of the antenna. 4) Check whether the dip angle planning of the base station is reasonable. 5) Whether there is blocking in antenna coverage direct vision. 4.2 Common Installation Errors GPS antenna blocked Disordered wiring The holding pole lightning rod is not led to the ground bar The GPS antenna is mounted on the front of the RF antenna 30 Without the lightning rod Disordered wiring of distribution box Power line and signal cable are crossed Multiply the grounding point The RF feed system does not connect, the cell is activated and RF transmits signal 31 Appendix A Terminology & Acronym Acronym Full Name ANR ARQ CA CC Automatic Neighbor Relations Automatic Repeat Request Carrier Aggregation Component Carriers CSFB Circuit Switched Fallback DC EPC GPS HARQ IPsec MIMO MME MOCN NLOS OPEX PAP PCI Dual Carrier Evolved Packet Core network Global Positioning System Hybrid Automatic Repeat Request Internet Protocol Security Multi Input Multi Output Mobility Management Entity Multi-Operator Core Network Non-Line-of-Sight Operating Expense Password Authentication Protocol Physical Cell Identifier PLMN Public Land Mobile Network QAM QCI QoS QPSK RSRP SSH Quadrature Amplitude Modulation QoS Class Identifiers Quality of Service Quadrature Phase Shift Keying Reference Signal Receiving Power Secure Shell 32 SON TAC Self-Organized Network Tracking Area Code 33
