No.: 00031UM Date: 6-Jul-17 Rev. 6.3 www.cobham.com/wireless Page | IX DIGIMINI AMERICAS REPEATERS PRODUCT DESCRIPTION AND USERS MANUAL 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 Coverage Document number: 00031UM Date: 6-Jul-17 Rev. 6.3 www.cobham.com/wireless Page |1-2 DIGIMINI AMERICAS REPEATERS PRODUCT DESCRIPTION AND USERS MANUAL 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 repeaters 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.

Cobham Wireless Coverage Document number: 00031UM Date: 6-Jul-17 Rev. 6.3 www.cobham.com/wireless Page |5-7 DIGIMINI AMERICAS REPEATERS PRODUCT DESCRIPTION AND USERS MANUAL 5.3.1 RF Gain Setting Criteria The RF Gain is set automatically by the Repeaters SALC function. 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 GSM GSM WCDMA WCDMA LTE LTE Filter BW 200KHz 11MHz
