3
Share a finite resource
Starting point: Blue Ribbon Panel ITC 2004: „Transition from spectum allocation ownership to capability based spectrum policies / strategies“ Spectrum range looks tremendously wide, but inherent propagation phenomena and technology restrict the use for radio communication up to 30 (300) GHz Commercials buy spectrum - A free market regulation can´t be the solution CSIS commission report calls for a change – „US spectrum management is outmoded „. A new policy of sharing between services / users needed! An IFT Sponsored Group
4
The new spectrum environment
Services with very different signal structures have to co-exist A certain interference level to be accepted – from non interference to a tolerable interference base! Exploit the potential of a dynamic allocation instead of static. But coordinaton function needed. Integrity of critical services has to be ensured An IFT Sponsored Group
5
Support of spectrum innovation
CSIS recommened: Develop optimum sharing strategies with a minimum probability of interference Exploit the remaining potential in bandwidth- limited, lossless communictions down to Shannon´s limit Motivate for a coordinated „live together“ and see, what levels of interference are acceptable Exploit the upper GHz – region (> 30 GHz) An IFT Sponsored Group

What to happen after WRC 2007??
5 additional bands for AMT under AI 1.5 study, in the range of 4,4 to 6,7 GHz If AMT getting additional allocations, sharing must occur with e.g. AM(R)S, ARNS, FSS & MSS (earth / space stations), MS(WAS), RAS.. Coordinating institutions needed, national & international Frequency range 16 to 30 GHz: to be studied for WRC 2010, needs a resolution of the WRC 2007 ! An IFT Sponsored Group
