1、QUESTION ITU-R 233/1*Measurement of spectrum occupancy(2007)The ITU Radiocommunication Assembly,consideringa) that frequency management is providing theoretical values, retrieved from planningsoftware regarding field strength values, produced by users of the frequency spectrum;b) that monitoring ser
2、vices are tasked to measure the frequency spectrum and compare thosevalues with the theoretical values from the frequency management;c) that different types of occupancy measurements are performed worldwide and that it isoften difficult to compare the results of those different methods,decides that
3、the following Question should be studied1 What techniques could be used to perform frequency channel occupancy measurements,including processing and presentation methods?2 What techniques could be used to perform frequency band occupancy measurements,including processing and presentation methods?3 H
4、ow can “occupancy” defined for both, frequency channel as well as for frequency bandmeasurements, also taking into account, the size of the used filter and the values measured inadjacent channels?4 How can threshold levels be defined and applied in practical situations including dynamicthreshold levels?further decides1 that the above studies should be included in Recommendation(s);2 that the above studies should be completed by 2011.Category: S2* In the year 2009, Radiocommunication Study Group 1 extended the completion date of studies for thisQuestion.
