3.4 Remote Unit
There are many different kinds of remote units with a wide range of gain and output power to cater
to many different needs. A low and medium power unit can house up to 4 different frequency bands
in one unit, the high power versions can handle up to 2 different bands in one single unit.
Chassis types
RUs comes in mainly two different chassis, a single compact chassis for 1-2
bands and a dual chassis for up to 4 bands. This is how they can be
configured:

It is also possible to have combinations of the
above. For example it is possible to build a dual
chassis with 2 medium power bands and 1 high
power band in the same remote. Each side of a
dual chassis is virtually identical to a single chassis
remote unit. This ensures unparalleled flexibility
when building multiple operator / multiple band
solutions.
A dual chassis may have 1-2 optical remote units
(FOR). This way they can be fed from different
directions for redundancy.
Remotes can also be daisy-chained by way of RF cables, meaning up to two
chassis can share the same fiber-optical interface providing up to 8 bands in a
single location. Variants are available upon request.
Commonly for all Remote Units is their excellent noise figure, contributing to
an overall noise figure for the whole system from remote to head-end into
the base station of < 3 dB for the RF link.
Both chassis complies with IP65 protection for use in any environment. The coating is a durable
coating which eases the convection cooling. No fans are used for the DeltaNode Remote Units. Both
chassis are available both with wall and pole mounting kits as requested.
External Antenna´s that are most commonly used in combination with DDS Remote Unit family for
outdoor environment are 17 dBi gain antennas. Antenna used for MPE radiation calculation is a 17
dBi antenna.
Most commonly used manufacturers antennas in combination with DeltaNode DAS systems to our
knowledge are Cellmax, Kathrein and Amphenol antennas, and we believe that these manufacturers
holds best RF quality and performance.
