ITU-R REPORT SM.2156 PDF

This Report discusses the role of spectrum monitoring in support of inspections, supported with examples. Where the link of spectrum monitoring with inspections is very strong or direct we can speak of monitoring in support of inspections. To avoid misunderstanding it needs to be clarified that this support and "on site inspections" are not interchangeable but could be complementary in the total inspection process.

The Report also contains national examples of prototypes and operational monitoring mechanisms in the form of annexes. The task of conducting spectrum monitoring in support of inspections is not new but superior results are obtained due to improvements in automatic control of monitoring equipment.

A technique discussed is the use of common monitoring/measurement equipment for triggering an inspection by recording the same parameters that would be recorded during an inspection. Monitoring results obtained with this equipment can be used to select candidates for an "on site" inspection. These monitoring processes do not form a replacement for on site inspections but can be used to save money in situations where otherwise a large number of expensive and sometimes unique measurement setups would be required.
