AXELL DIGIMINI- AMERICAS REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

1 Introduction

Axell Wireless DIGImini (digital mini) is a scalable in-building mini-repeater with advanced digital

filtering capabilities. Each repeater supports two bands where two repeaters can be easily cascaded

into a compact assembly to provide tri-band and quad-band solutions.

For each band, the user can configure up to six non-contiguous sub-bands, where the gain and power

of each of the sub-bands can be individually defined. The Repeater provides highly accurate out-of-

band-rejection and simple, GUI based procedures for adjusting the pass band according to the

relevant frequency spectrums.

DIGImini includes the SmartALC power control algorithm that automatically optimizes the gain

setting by learning the actual range of RSSI levels over a user-specified period of time. The

SmartALC algorithm prevents oscillations, reduces the amount of isolation required by the system

and optimizes the system to minimize noise rise at the donor cell site.

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. Local Web

based management is available via an RJ45 connection.

Optional, complete, remote Web-based management via a GPRS/CDMA modem provided by the

DIGImini Control Unit (DMCU). The DMCU is ordered separately, where a single DMCU can

support a single DIGImini or two cascaded units.
