Performance Issues with the R450 System
This section addresses situations where the system is functioning but
the R450 DC or MIU communication is not performing as expected.
This discussion covers two situations.
l
The first is getting the newly installed system to perform per
specification.
l
The second covers an installed system where the performance
degrades suddenly or over time.
Optimizing the Performance of a New System
Before you install the system, Neptune uses computer software and
other resources to predict the performance of the system and
recommends a minimum number of R450 DCs to provide the desired
performance. Each site has a survey performed that provides
recommendations on antenna placement and looks for potential radio
interference problems. These steps can identify many of the potential
problems but may not be able to identify all the problems encountered
during installation and maintaining the system. Neptune provides a
propagation model which uses sophisticated software to predict the
system performance. If you place an R450 DC somewhere else, it may
not perform well.
CAUTION: If Neptune's propagation model is not followed,
then inadequate performance can occur.
Owners of both licensed and unlicensed equipment are
responsible for the proper operation of their equipment. If it is not
operating within specifications, the owner is required to bring the
system into compliance or stop using it. This can be beyond the
capability of most homeowners and small businesses, requiring a
cooperative effort to solve.
It is possible for a piece of equipment to be functioning totally within
its required specifications and still cause interference with the R450
System. The collaborative effort of all the affected parties is required
to solve this type of problem.
During the initial installation of a site, Neptune advises using a
receiver or high quality spectrum analyzer connected to the antenna to
assure that the transmit and receive frequencies are free from
