In addition, the FCC recommends that all operators and installers register with the WISPA
database used by government agencies to quickly find devices that may be causing interference
and notify their owners/operators to shut them down. This registration is not required, but Fortress
strongly recommends that all systems be registered, as described in this excerpt of KDB 44399:
A voluntary WISPA sponsored database has been developed that allows operators and
installers to register the location information of the UNII devices operating outdoors in the
5470 – 5725 MHz band within 35 km of any TDWR location (see
http://www.spectrumbridge.com/udia/home.aspx
). This database may be used by
government agencies in order to expedite resolution of any interference to TDWRs.
KDB 443999 further specifies that the requirements of KDB 594280 must also be met.
KDB 594280 is published in full on the FCC web site:
https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=39498
.
This device meets KDB 594280 by not allowing any configuration options to be made such that the
device could be taken out of compliance. There is no ability for the user to change country codes
or to select power levels that would take the device out of compliance.
For customers such as the U.S. military or others willing to produce evidence that particular
devices will be used only outside of the United States, a special license can be obtained from
Fortress that will allow those devices the option of selecting a different, non-U.S. country code.
Fortress creates such licenses only for those customers who offer proof of non-U.S. device usage,
and licenses are specific to particular devices and are not transferrable. Devices having such a
license should NOT be considered to be compliant with FCC regulatory requirements. Please
contact Fortress with questions about these special licences.
Only software that has been signed by Fortress using the Fortress private key can be loaded onto
a Fortress device, thus insuring that no software other than that which is controlled and signed by
Fortress can by loaded onto the device.
