Warning
To comply with FCC RFexposure compliance requirements, each individual
antenna used for this transmitter must be installed to provide a separation
distance greater than 205cm or more from all persons during normal operation
and must not be co-located with any other antenna for meeting RFexposure
requirements.

Warning
This is NOT a CONSUMER device. It is designed for installation by
FCCLICENSEES and QUALIFIED INSTALLERS. You MUST have an
FCCLICENSE or express consent of an FCCLicense to operate this device.
Unauthorized use may result in signi cant forfeiture penalties, including penalties
in excess of $100,000 for each continuing violation.
2.7 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
2.8 K-BOW System Architecture
The K-BOW system architecture is described in the document K-BOW System Description.
