1.1 Purpose This User Guide is intended as an instruction manual for professionals to provide step-by-step instructions for setting up and initial configuration of the AirUnity 588 unit. 1.2 Intended Audience This guide is intended for persons who are responsible for installing and performing initial configuration of the AirUnity 588 unit. 2 Warnings and Cautions 2.1 Human Exposure to Radio Frequencies To comply with FCC RF exposure compliance requirements, the device should be located at a distance of at least 20 cm (7.87 in.) from all persons during normal operation. The antennas used for this product must not be co-located or operated in conjunction with any other antenna or transmitter. 3 AirUnity 588 Installation Note: The optimal window placement for the AirUnity 588 is the side of the building with a direct line of sight to the nearest cell tower The AirUnity 588 unit is placed on the window sill to receive the signal from outdoors and boost it indoors. The following steps instruct on the proper positioning and setup of the AirUnity 588 unit for optimal service. 3.1 Unpacking and Checking the Unit 1. Carefully unpack the AirUnity 588 unit from the box. 2. Inspect the unit for any damage and check that all the accessories are in the box. 3. Remove the Power Supply (included) from the packaging 3.2 Finding the Best Location Choosing an appropriate window at the suitable side of a building is vital to get the best performance The AirUnity 588 has a built-in capability to survey the 4G signal from suitable provider cell towers & also use GPS to accurately determine its location. It can do this for multiple windows in the same or on multiple floors, ideally in all four directions of the building. o Connect the power supply to the underside of the AirUnity 588 and place it at the 1st window (ideally in the middle of the window). Note: After 1 minute, the unit will automatically commence the test, with a 30 sec countdown timer o Wait for the RF survey to complete o Go to the next window and repeat the survey process o Test as many windows as possible, in all four directions if possible o Once you finish testing all locations, select the best location out of all surveyed locations and press Install Here in the location DUG01689 Airspan Commercial and Internal Use 5 AirUnity588 User Guide Note: After 1 minute (in good RF conditions - otherwise after 5 minutes) the unit will automatically commence the installation, with a 30 sec countdown timer. DUG01689 Airspan Commercial and Internal Use 6 AirUnity588 User Guide 4 Initial Setup The AirUnity 588 turns on automatically when the power supply unit is connected to the underside of the unit and plugged in. 1. Place the AirUnity 588 near a window and verify that the unit is positioned correctly so that the display faces into the room. Note: Choose windows that are in close proximity to an available power supply outlet. Note: When deploying the unit select a location raised above the windowsill for optimal connection to the network. 2. Shortly after the application of power, the following will be displayed while the unit is starting up. Figure 1 Start-up Note: This process can take several minutes. The AirUnity 588 scans for LTE backhaul DUG01689 Airspan Commercial and Internal Use 7 AirUnity588 User Guide Note: At this point (scan finished), it is possible to access the Cell ID and RSRP of the strongest Donor Cell detected during first frequency scan i.e. before Plug-and-Play is complete. Press the hamburger icon and enter network settings to reach the LTE Backhaul status screen. Please note: this may not be the same cell as acquired when plug-and-play is complete.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help 10.9 Service Information Refer all repairs to qualified service personnel. Do not modify any part of this device, as this will void the warranty. Disconnect the power to this product and return it for service if the following conditions apply:

a. The unit does not function after following the operating instructions outlined in this manual. b. The product has been dropped or the housing is damaged. Locate the serial number of the terminal and record this on your registration card for future reference. Also record the MAC address, located on the product sticker.

This private key is generated in the factory, and so is the corresponding vendor certificate. This capability is necessary in order to support large scale plug and play deployments. This device key is stored on the AirUnity 588 to allow it to authenticate to the network. If the private key is compromised, then the device can be masqueraded by an attacker towards the operators core network. Therefore, it is stored in an encrypted form. DUG01689 Airspan Commercial and Internal Use 38 AirUnity588 User Guide 16.2 Unused Port Security Unused interfaces on the SoCs within AirUnity 588 are protected against attack by ensuring that the corresponding pins are not connected to tracks on the circuit board. In addition to this hardware protection the device drivers within the SoCs which service these ports are disabled. 16.3 Tamper Detection Simple tamper detection is provided in AirUnity 588 by the use of tamper-evident label covering the SIM holder. The SoC within the AirUnity 588 unit supports secure boot. Enabling secure boot ensures that only trusted software will run on the SoCs internal to AirUnity 588. AirUnity 588 supports FCAPS capabilities including the following:

Configuration Management Inventory Management Fault Management Performance Management Software Management Diagnostics AirUnity 588 is managed remotely via Airspans NMS (Netspan) using SNMP and supports management using a default IP address. The NMS is automatically detected via plug and play procedures implemented in the AirUnity 588 and Netspan software. Airspans Netspan node management system supports management of all Airspan products. 17 Standards Compliance 17.1 TUV Marking The AirUnity 588 bears the TUV conformance mark. Product conformity is based upon the AirUnity 587 which is FCC Approved with the addition of Radio testing according for Band 3 and Band 28 according to 3GPP TS36.521-1 and 3GPP TS36.521-2 The AirUnity 588 product is not CE marked. 17.2 Environmental AirUnity 588 is designed to meet the following environmental requirements:

AirUnity (Mobile Digital Stations) The EUT, Mobile Digital station, AirUnity 3.55-3.7GHz, Band 48, is part of a LTE broadband fixed cellular wireless access system. The system provides a radio link between an end-user (a subscriber) and a network to give high-speed data access. The AirUnitys transceiver/receiver (Up to 256 QAM modulation, data rate up to 143 Mbps) equipped with a 10dBi internal antenna. Advanced Antenna Techniques 2x2 MIMO are supported. The maximum RF output power (not including antenna gain) is 22.49 dBm for 10dBi and it can be reduced by software. Antennas 1/2 is one sector and antennas 3/4 is another sector. The AiUnity is installed intdoors. The Subscriber transmits and receives traffic to and from the base station respectively. The transceiver provides subscribers with "always-on" Internet, high speed data only, or data and voice (VoIP) services and is configured with a unique base station reference number, preventing the LTE UE from relocating to another subscriber premises without authorization. Note:The AirUnity equipment defined as Category A CBSD (Citizens Broadband Radio Service Device) Antennas 1/2 arrange one sector while antenna 1 is cross polarized to antenna 2 and antennas 3/4 arrange another sector while antenna 3 is cross polarized to antenna 4. The transmitter output signals are completely uncorrelated. The transmitter output signal are completely uncorrelated, antennas 1 / 2 is one sector and antennas 3 / 4 is another sector!
