Considerations for Re-Radiation (Over-the-Air) Systems
Fusion Wideband can be used to extend the coverage of the outdoor network by connecting to a
roof-top donor antenna pointed toward an outdoor Base Station. Additional considerations for
such an application of Fusion Wideband are:
siz
ing the gain and output power
requirements for a bi-directional amplifier (repeater)
ensuring that noise radiated on the up
link from the in-building system does not cause the
outdoor Base Station to become desensitized to wireless handsets in the outdoor network
filtering out signa
ls that lie in adjacent frequency bands. For instance, if you are providing
coverage for Cellular B-band operation it may be necessary to filter out the A, A’ and A” bands
which may contain strong signals from other outdoor Base Stations.
Further information on these issues can be fo

applications.
