Link End Assessment

Using Ofcom guidelines, TNEI now has the expertise to perform link end analysis in house. TNEI are able to produce and submit reports to mobile link operators in order to seek to remove objections or reduce required buffers to enable turbine schemes to progress.

Wind turbines are thought to interfere with microwave links in three separate ways: nearfield effects, diffraction and reflection. To avoid interference from these effects three exclusion zones can be constructed along the path of an existing communication link. If turbines are positioned such that they do not encroach on these exclusions zones, the turbine will not affect the link.

For many sites, two dimensional analysis is sufficient to ensure that turbines do not interfere with existing links and this is the preferred method of link operators. In reality, however, the exclusion zones are three dimensional volumes which are not fully represented on two dimensional maps. For more complicated sites it is necessary to perform full three dimensional space analysis to confirm or prove that the turbines will not interfere with microwave links. Using approved Ofcom guidelines, TNEI has the expertise to perform three dimensional link end analysis. TNEI can produce and submit reports to mobile link operators in support of turbine applications in sites where we believe unfounded objections have been raised.

TNEI staff has close ties to the telecommunications industry and can negotiate directly with operators to resolve any potential conflicts.
