In Germany seven paired 7MHz blocks around 3.5 GHz (some Germany-wide, others only available in some of the 16 regions) are
being auctioned off now. Interest level is surprisingly very high. A
report from Golem.de says there have been 1,221 applications filed by 102 bidders so far.
The German regulator Bundesnetzagentur runs what they call a hearing until August 4, 2006 where everyone can hand in comments. Thereafter the auction should happen. The original deadline was end of 2005.
The auction does not require the biddders to use any specific technology - although one can expect that it will be WiMAX.
