This manual describes the Axell D-SBR 3709S IP65 High Power Digital Channel/Band
Selective Repeater. The repeater is designed for indoor installations and includes
advanced filtering capabilities to support the SMR 900MHz band for public safety and
commercial operations.
The D-SBR 3709S repeater supports up to eight non-contiguous sub-bands/channels,
where the gain and output power of each sub-band is independently tunable across the
entire band. This provides an optimal solution for operators that have a non-contiguous
spectrum.
The system supports advanced Digital Signal Processing (DSP) technology,
programmable digital filters. These capabilities enable the user to quickly and simply
customize the Repeater according to changing site requirements.
Highly linear MCPA components and unparallel innovative DSP filtering provide top level
performance that support high throughput of the latest modulation technologies such as
HSPA and LTE.
The Smart-ALC power control algorithm automatically optimizes the gain setting by
learning the actual range of RSSI levels over a user-specified period of time. The Smart-
ALC 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.
Intuitive Web access monitoring and management GUI is accessible via a local or
remote Ethernet connection.
