Is There an 'Interference Temperature'? FCC Seeks to Quantify Interference

The FCC is eyeing a possible new way to quantify and manage interference among services. It cited the "ever increasing demand for radio spectrum" and "the additional challenges this presents for effectively managing interference."
The model is called "interference temperature" and takes into account the cumulative RF energy from transmissions of spectrum-based devices; it would set a maximum cap on the aggregate of these transmissions.
The existing approach focuses on specifying and limiting the transmit powers of individual devices as the chief way to prevent interference.
"The 'interference temperature' approach may facilitate more intensive use of the radio spectrum, creating the opportunities for new services and improving the predictability of any interference to existing services," the FCC stated. It has put out a notice of inquiry asking for comments on the concept, which was among the recommendations of its Spectrum Policy Task Force.
The FCC wants comments on rules that would use this model on a limited basis in the 6525-6700 MHz and portions of the 12.75-13.25 GHz bands.
"These procedures would enable unlicensed devices to operate in these bands, which are used primarily for satellite uplinks and fixed point-to-point microwave services," it stated.
