Radio Regulation Summit: Defining Inter-Channel Operating Rules

September 8 and 9, 2009

Radio regulators have been slow to develop comprehensive generic rules on inter-channel interference, that is, out-of-band and adjacent channel interference. This issue has been dealt with on an ad hoc, band-by-band basis. This worked while technologies/services were relatively static, users were more or less immobile, and there was less rivalry between frequency-adjacent radio users with divergent technologies and business models.

On September 8 and 9, 2009, the Silicon Flatirons Center brought together a select group of engineers, policy makers, academics and company representatives to develop a general approach to defining rights regarding inter-channel interference that will facilitate investment in radio systems, and the resolution of conflicts among rights holders.

A report on the findings of this summit is available here (PDF) and here (DOC).
