The second key issue at WRC-12 is the regulatory measures that could enable deployment of cognitive radio systems (CRS). CRS are a main enabler of spectrum commons as they are capable of transmitting dynamically in the temporarily unused frequencies without the need of exclusive allocation. During WRC-12 some concerns were expressed regarding interference between CRS and space, passive and safety services. Countering this, however, others argued that national regulators can set operating parameters for CRS devices through equipment authorization requirements to ensure they will not cause interference. Ultimately, WRC-12 did not decide on any particular measure with regard to CRS, and recommended that any radio system implementing CRS technology should operate in accordance with the provisions of the ITU Radio Regulations.
