Digital Multi-Band Mini Repeater 900/1800/2100/2600MHz

Description

Digital Multi-Band Mini Repeater

  • Innovative digital mini repeater at price of legacy analog mini repeater
  • Up to four frequency bands in two compact enclosures
  • Software Defined Filtering of up to 6 sub-bands in each individual frequency band
  • Single and dual band units for 900/2100 MHz and 1800/2600 MHz
  • Individual gain and ALC settings for each sub-band for single and multi-operator applications
  • Ideal for flexible In-building applications

Cobham Wireless’ 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) applications, multiple filters are required in the operation bands.

The DIGImini is designed to provide high performance digital filters with a competitive price to legacy analog mini repeaters.

Up to four different frequency bands can be implemented in 2 dual band DIGImini repeaters. Each DIGImini repeater can be a single band 900/1800/2100/2600MHz or dual band 900/2100MHz or 1800/2600MHz.

Easy “plug and play“ allows our customers to add services as needed, thus minimizing their CAPEX. Software Defined Filtering of up to 6 sub-bands in each individual frequency band can be supported in a single or dual band configuration. Individual Gain and ALC settings for each sub-band for multi-technology applications (e.g GSM/WCDMA) for single and multi-operator applications.

A state-of-the-art Interference Mitigation and Oscillation Prevention (IMOP) 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 wireless modem.

With the Cobham Wireless advanced supervision and control software, the entire fleet of digital multi-band repeaters can be  monitored.

Cobham Wireless’ DIGImini repeater is powerful enough to drive a passive Distributed Antenna system (DAS) for coverage areas up to 25000 ft2 (2500m2) in buildings, parking lots, malls, warehouses and offices.

Cobham Wireless was formerly known as Axell Wireless
