2.3 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. The system offers mobile radio single routing capabilities to support exible
sectoring for network load balancing as well as individual signal power optimization of
remote RF unit level. The system use cases are the following:
●
Operating K-BOW as a repeater by
– interfacing cable based RFsignals from base stations to the C-hub,
–
relaying the radio signal of the base stations into at least one or multiple radio cells via
remote units with antennas connected to these using coaxial cables,
●
Routing base station signals
●
Supporting MIMO operation on selected bands
