MK-MAN-01 CarrierWave Digital Radio
The CarrierWave Digital Radio includes integrated Operations, Administration, Maintenance, and
Provisioning (OAM&P) functionality and design features enabling simple commissioning when the
radio network is initially set up in the field at the customer’s premises. Furthermore, a highlight of
CarrierComm’s radio products is scalability and the capability to support a ring-type architecture.
This ring or consecutive point radio architecture is self-healing in the event of an outage in the link
and automatically re-routes data traffic, thereby ensuring that service to the end user is not
interrupted.
The overall architecture consists of a single 2RU rack mount Indoor Unit (IDU) with a cable
connecting to an Outdoor Unit (ODU) with an integrated antenna. There is an option for
interfacing the ODU with an external antenna (contact factory for availability). The IDU/ODU
architecture is advantageous when compared to a single IDU with external mount antenna since
supporting a signal of 5.8 GHz from the IDU rack to the antenna will experience significant signal
degradation requiring expensive coaxial cable or waveguide.
