Abstract
From the monitoring of signal levels in the land-mobile bands over a period of 10 consecutive days, it is shown that the base-station levels remain constant within + or - 2dB and can be used for isolating station occupancy from that due to mobiles. It is also shown that a monitoring period of 4 to 5 days gives reliable estimates of; 1) the mean daily occupancy and 2) the 75% level of the cumulative distribution of occupancies measured in 5, 30 or 60 minute periods. Only a few (8%) of the frequencies showed a systematic difference of occupancy between the morning and afternoon values and it was found that there was no statistical difference between the occupancy of a frequency monitored for 5 minutes every 10 minutes and for 5 minutes every 30 minutes.
