1 Introduction
Axell’s Digital Multi-Band Repeater for USA (D-MBR-USA) is an in-building, band-selective
repeater with advanced digital filtering capabilities that operates in the LTE 700MHz (simultaneously
in upper and lower band), CELL 850MHz, AWS 1700MHz and PCS 1900MHz bands. It provides an
excellent single unit solution for multi-operators or for operators with a non-contiguous spectrum.
Up to eight or twelve (model dependent) non-contiguous sub-bands can be user configured for each
band, 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.
D-MBR-USA 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.
GUI based web management is supported through both Ethernet and remote wireless connections
provided by an integrated CDMA modem. Local setup can be performed through a connection to the
Ethernet port using a cross-cable.
