CEPT: Technical Background For Self-Coordination
Extract from Annex 3 of ECC Recommendation (09)01, available here:
http://www.erodocdb.dk/Docs/doc98/official/pdf/Rec0901.pdf
To assist the planning of PP fixed links, self-coordination approach, similar to the “light licensing”,
described in ECC Report 80 [25], can be considered. Such regimes do not mean “license exempt” use,
but rather using a simplified set of conventional licensing mechanisms and attributes within the scope
decided by administration. This planning is delegated to the licensee.
Administrations intervene for protecting a limited number of sensitive sites while giving greater
flexibility elsewhere than it could be allowed without the geographical limitation.
This process requires to record for instance the following set of simple criteria for each authorized link
and makes the data available publicly to assist in the identification of operational parameters and to
conduct interference analyses:
Date of application (in order to assign priority);
Transmit, receive centre frequencies and occupied bandwidth;
Equipment type, specifying relevant transmitter/receiver parameters;
Link location (geographic coordinates, height/direction of antenna, etc.);
The antenna gain and radiation pattern.
Subject to the conditions set by the administration, it is left to the operator to conduct any compatibility
studies or coordinate as necessary to ensure that harmful interference is not caused to existing links
registered in the database. For example, an operator wishing to install a new link could calculate the
interference that the new link will create to the existing links in the database. Then it will be possible to
determine whether this new link will interfere with existing links. If so, the new link could be re-planned
to meet the interference requirements of existing links in the database. Otherwise, the new link may be
also co-ordinated with existing operators, who might suffer from the interference.
To assist with the resolution of disputes, licenses are issued with a “date of priority”: interference
complaints between licensees may therefore be resolved on the basis of these dates of priority (as with
international assignments).
