Radio frequency technical monitoring is one of the most important spectrum management tools that ensure the orderly performance of spectrum usage nationally, and the protection of legal spectrum allocations against interference resulting from illegal uses.
RF Spectrum Monitoring means:
- Measuring the technical parameters of authorized emissions for license compliance
- Identification and localization of illegal transmitters
- Resolving the cases of harmful interference
Important activities of frequency monitoring are as follows:
- Regular Monitoring
RF Spectrum is monitored according to an annual monitoring plan to detect the transmission of the unauthorized stations, and also to detect out- of- band emissions which could cause a harmful interference to the authorized user. The identified illegal transmitters are localized by using the mobile monitoring stations.
During The Regular Monitoring, the following tasks are carried out:
- Measurement of frequency, modulation, bandwidth etc. to ensure adherence to licensed technical parameters.
- Detection and localization of illegal frequency usages with the help of Mobile Monitoring stations.
- Resolution of interference and enforcement.
- RF spectrum occupancy recording to determine the spectrum usage, ranges of unused frequencies and to assist other departments on demand.
- Direction Finding
The purpose of radio direction-finding is to determine the position of any source of electromagnetic radiation by means of the propagation properties of radio waves. Radio direction finding is used to determine the position of a radio transmitter or a source of radio noise which can not be identified by any other means. Direction finding systems are mounted in the fixed and mobile monitoring stations.
- Interference Resolution & Enforcement
Monitoring of the cases of harmful interference to detect, locate and eliminate the source of interference to protect the assigned users .
- Frequency Allocation For Distress And Safety Purposes
Regularly monitoring of the frequencies reserved for distress and safety communication to keep them free of interference to safeguard the human lives.
