2.6 Intended Use
The K-BOW system is a micro C-RAN solution to provide exible and ef ciently scalable
coverage and capacity for multi-operator and multi-band scenarios using a common
infrastructure. K-BOW offers mobile radio single routing possibilities to support exible
sectorising for network load balancing as well as individual signal power optimisation of
remote RFunit level. Therefore, the applicable use cases are the following:
●
Operating K-BOW as a repeater by
– interfacing the C-HUB cable-based with the RFports of mobile radio base stations and
–
relaying the radio signal of the base stations into at least one or multiple radio cells via
remote units with either integrated antennas or antennas connected to remote units
by coaxial cables
●
Routing of base station radio signals
●
MIMO support of selected bands by using the integrated MIMO antennas within the
remote units or by connecting two antennas to the remote units
2.7 K-BOW System Architecture
The K-BOW system architecture is described in the document K-BOW System Description.
2.8 Qualification of the Personnel
The personnel who installs, calibrates, operates, maintains and repairs the K-BOW system
must
● be authorised and suitably quali ed,
● be regularly instructed and trained in all issues concerning operational safety and
environmental protection, and
●
know the system documentation and the safety instructions contained therein.
2.9 Preconditions and Requirements
Warning
Risk of injury due to incomplete installation.
► The measures described in the Installation Manual (K-BOW Platform 2) must be fully
completed before implementing the measures indicated in this document.
► Make sure the Installation Manual (K-BOW Platform 2) is present, so that, where
necessary, the cabling can be checked and the safety instructions are available.
