USA specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to
implement special features to prevent interference to weather radar systems that
operate in the band 5600 MHz to 5650 MHz
.
These features must be implemented in
all products able to operate outdoors in the band 5470 MHz to 5725 MHz.
Manufacturers must ensure that such radio products cannot be configured to operate
outside of FCC rules; specifically it must not be possible to disable or modify the radar
protection functions that have been demonstrated to the FCC.
In order to comply with these clear FCC requirements for all manufacturers, Motorola
is releasing new versions of PTP 300 and PTP 500 for USA or Canada operation. These
new devices will only be allowed to operate with licence keys/region codes which will
comply with FCC/IC rules.
Other versions of the products will be available for use in the rest of the world, but
these versions will not be supplied to the USA except under strict controls, when they
are needed for export and deployment outside the USA.
Installers must follow this procedure when deploying PTP 300 or PTP 500 links in the
USA or Canada:
Check whether either master or slave units are being installed within 35 km of a
TDWR system or have a line of sight propagation path to such a system. This can
be checked by visiting http://spectrumbridge.com/
u
drs/home.aspx.
If a TDWR system is located within 35km or has line of sight propagation to the
PTP device, then the installer must:
o Register the installation on http://spectrumbridge.com/
u
drs/home.aspx.
o Use channel barring to ensure a minimum of 30 MHz separation between
the TDWR frequency and the operating channel frequency of the PTP
system.
