apparatus and method for measuring traffic intensity in a digital mobile telephony gsm system and base station and site selection and antenna positioning method for gsm system

摘要

A method of measuring traffic intensity in a GSM digital mobile radio telephony system uses a spectrum analyser to measure a radio spectrum for radio emissions from the system. The spectrum analyser employs a rapid frequency sweep so that each channel of said GSM digital mobile radio telephony system is measured during a time period which is less than a GSM time gap. The measurements are performed on the uplink radio transmissions from mobile transceivers. The method can be used to measure traffic intensity in all GSM systems carrying traffic at a given location. The method includes the following steps: setting the frequency analyser to make frequency sweeps over selected GSM channels in a GSM frequency band; setting the frequency analyser's sweep time so that for each GSM channel a signal intensity is measured at a plurality of points during a time interval which is less than one GSM TDMA time gap; and if the signal intensity measured at said plurality of points exceeds a user set threshold value, recording a measured signal as traffic.
