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.
