Ofcom publish 3400 MHz repsonses

The 3400 - 3600 MHz consultation held by Ofcom closed on Friday November 20, and the responses are now available.

The joint response from the Radio Society of Great Britain, UK Microwave Group, Amsat-UK and BATC to the OFCOM Crown Recognised Spectrum Access in 3400 to 3600 MHz provides much information on Amateur Radio activity at 3400 MHz and among the points made are:

Question 1:
Whilst certainly not enthusiastic regarding the concept we recognise that the MoD has embarked on the process.
Our prime interest is in maximum protection and our own development in the 3400-3410MHz subsection of the Amateur 3400-3475MHz allocation. This allocation though on a Secondary basis is based on ITU RR footnote and is also subject to CEPT ECA allocation footnote EU171

For Qs9-12:-
It is important that outdoor terminal equipment be full specified so that out-of-band emissions are at acceptable limits for adjacent existing users, especially ourselves with sensitive weak-signal receivers.

For Qs14-16:-
We believe there is considerable merit in Government applications in conjunction with Amateurs and PMSE-use in coalescing at the bottom of the 3400 band (perhaps in the 3400-3440 range) following a trade as per Para 8.62, to give one contiguous area for existing users and freeing the rest of the band for mobile/broadband services. This will result in maximum spectrum efficiency, but only if Ofcom and other users reconsider the need for symmetric duplex operation as more spectrum will be free above 3500 than below. Such a move will have significant implications for both the 3440 MHz (or wherever) block edge, as well as the lower UK-Broadband block edge.
