DIGIMINI AMERICAS REPEATERS PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 6-Jul-17 www.cobham.com/wireless Doc. No.: 00031UM Rev. 6.3 Page | VI Compliance with IC WARNING!! This is NOT a CONSUMER device. It is designed for installation by an installer approved by an ISED licensee. You MUST have an ISED LICENCE or the express consent of an ISED licensee to operate this device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the antenna and your body. La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la valeur nominale de 3.5 dB, surtout si le signal de sortie est retransmis et qu'il peut causer du brouillage aux utilisateurs de bandes adjacentes.

DIGIMINI AMERICAS REPEATERS PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 6-Jul-17 www.cobham.com/wireless Doc. No.: 00031UM Rev. 6.3 Page | 1-1 1 SYSTEM DESCRIPTION Cobham Wireless’ new DIGImini repeater (digital mini repeater) is an innovative flexible multiband coverage solution optimized for in-building applications. Cobham Wireless’ DIGImini offers a completely new range of possibilities. With multi technology (e.g GSM/WCDMA/LTE) applications, multiple filters are required in the operation bands. The DIGImini is designed to provide high performance digital filters with a competitive price when compared to legacy analogue mini repeaters. Up to four different frequency bands can be implemented in two dual band DIGImini repeaters. Each DIGImini repeater is available in a range of single-band and dual-band models, where specific single-band models can be updated to dual-band (requires license). Easy “plug and play” allows our customers to add services as needed, thus minimizing their CAPEX. Software Defined Filtering of up to 8 sub-bands in each dual band configuration and up to 16 sub-bands for quad band configuration. Individual Gain and ALC settings for each sub-band for multi-technology applications (e.g. GSM/ WCDMA/LTE), as well as for single and multi-operator applications. A state-of-the-art Interference Mitigation and Oscillation Prevention (IMOP) algorithm is used to measure the isolation between the antennas and gain is reduced immediately to prevent oscillation. The DIGImini is connected to one donor antenna placed on the roof of the building and the radiating coaxial cable or antennas in the area to be covered. Configuration and monitoring of the DIGImini can be done through an intuitive web management GUI. Remote management is done via optional wireless modem. With the Cobham Wireless advanced supervision and control software -AEM, the entire fleet of digital multiband repeaters can be monitored. Figure 1-1. Cobham Wireless DIGImini Repeater

DIGIMINI AMERICAS REPEATERS PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 6-Jul-17 www.cobham.com/wireless Document number: 00031UM Rev. 6.3 Page |1-3 1.2 Single Unit and Dual-Unit Installations DIGImini installation varies depending on whether one or two units are installed: • Single DIGImini unit (supports single-band or dual-band) – details in Chapter 3. • Dual DIGImini assembly (up to four bands) – details in Chapter 4 1.3 Single Band Unit Upgradeable to Dual-band Single-band units can be upgraded to support two bands by acquiring the appropriate license file from Cobham Wireless support team. 1.4 Smart-ALC Function The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for automatic repeater gain adjustment per sub-band. Combined with advanced control algorithms, SALC is capable of learning the traffic load characteristics and adjusting the Repeater RF Gain to the desired value. Smart ALC eliminates the need to perform initial settings for maximal traffic load conditions and on-site gain adjustments. Smart-ALC maintains the Uplink/Downlink gain balance for system transparency. In addition, Smart-ALC prevents oscillations that may occur due to insufficient isolation while maintaining the gain in a linear range operation by adjusting the repeater paths’ gain accordingly. IMOP (Isolation Measurement and Oscillation Prevention) algorithm effectively reduces oscillation problems. The repeater’s power amplifier includes power-monitoring circuits with Automatic Level Control (ALC) that prevents excessive output power while maintaining the power amplifier linearity. 1.5 DMCU - Optional The DMCU (DIGImini Control Unit) provides complete remote control and monitoring capabilities over WCDMA/GPRS, including Remote control via SMS. The DMCU is an optional control unit that is ordered separately and is installed externally, where one DMCU can support a single DIGImini unit as well as an a DIGImini Quad-band assembly. NOTE: Refer to the DMCU User Manual for the complete description of the DMCU and the configuration and management capabilities provided by the unit.

The function sets the optimum gain without exceeding the isolation limit. The gain range is up to 73dB for all bands and is set by default to its maximum value. The gain will then be modified automatically to its optimum value by the SALC mechanism. This mechanism performs gradual learning of traffic load characteristics and adjusts the Repeater RF Gain accordingly. (See section 1.2 for more information on the SALC mechanism). 5.3.2 Bandwidth and the Number of Available Sub-Bands Each repeater supports up to two bands, where a maximum total eight sub-bands may be defined for both bands (e.g. two sub-bands for one band and six sub-bands for the other band). NOTE: Since some sub-bands require more resources, less than eight sub-bands may be available. The sub-bands are available resources are listed in the Band Info tab of the repeater. This section provides a general description of the sub-band resource allocation as well as the Band Info tab. 5.3.2.1 Sub-band Resource Allocation A maximum eight sub-bands may be defined per repeater (single- or dual-band). The number of available sub-bands or channels depends on the technology and selected bandwidth as detailed below (note that some bandwidths (e.g. 15 or 20MHz at 1900MHz WCDMA) take up two channel resources). The following table summarizes the number of available sub-band resources under various configurations. Technology Filter BW Resources GSM 200KHz – 11MHz (in 200KHz steps) 1 GSM 11.2MHz – 20MHz ( in 200KHz steps) 2 WCDMA 5MHz, 10MHz 1 WCDMA 15MHz, 20MHz 2 LTE 1.4MHz, 3MHz, 5MHz, 10MHz 1 LTE 15MHz, 20MHz 2 5.3.2.2 Band Information Window The band information window provides general information on the repeater; this includes, Serial Number, Build versions, System ID (used when acquiring license files) and resources available for various filters.

Possible causes: Hardware failure, Circuitry failure, Software failure Recommended action: Wait 12 hours before contacting Cobham Wireless Support Temperature Description: High temperature indicated Possible causes: Unit temperature becomes high due to excessive heat. Recommended action: Check the Repeater case for external causes (sun, hot environment, air flow is blocked). Eliminate the reason for excessive heat. Donor Power Too Low Description: The signal from the Donor antenna is too low. Recommended action: Check connections and antenna position. (PAmp) Current Description: Generates an alarm when the Power exceeds the allowed limits. Possible causes: Fault in the DL or UL path, Downlink (Uplink) power amplifier module outputs a low current. Recommended action: Check the LEDs status in the Repeater System Mute Description. Generates an alarm when Repeater amplification is muted (automatically). Possible causes: Oscillation detected, Power at coverage port too high, Synthesizer failure, Hardware failure, Software failure, Out-of-band emissions out of spectrum, Interferer Power exceeded, Temperature. Recommended action: Contact Cobham Wireless Support User Mute Description: Repeater amplification is muted. Possible causes: Manual shutdown performed by operator. Recommended action: Review unit’s log Reduced Gain by IMOP Description: Alarm is generated when the IMOP mechanism was activated and the system reduces gain in order to respond to detected oscillations. Recommended action: Check the Donor and Mobile antenna installations for isolation. After isolation is within the required levels, the system will automatically increase gain (since it will no longer affect oscillations). Interferer Power Exceeded Description: Alarm is activated if external interference is at a level that may affect the operation of the unit. Recommended action: It is recommended to identify the source of the interference and distance the source or the unit from each other. NOTE: When the interferer is at HIGH Level it can cause the RSSI alarm to be ON as well RSSI Description: Generates an alarm when a high donor input signal causes system gain reduction
