Spectrum Management Process
Key elements in Spectrum Management:
Frequency Management
Licensing
Enforcement
Role of Monitoring :
To support these key-elements in order
to realise a usable and interference free spectrum

Principle of monitoring policy
’What can be done, using the equipment and
facilities of the (Remote) Fixed Monitoring Stations,
should not be done by Mobile Monitoring Stations.’
In remote areas more need for
direction finding equipment

Advanced Automated Spectrum
Management Systems
(AASMS)
• Modern spectrum management requires
integrated automated systems, including
monitoring results;
• Simple access to all types of information
by all staff involved in spectrum
management

Advantages of an AASMS
Direct and on line access
• For Frequency Planning & Licensing staff of
•
monitoring results
For Monitoring & Inspection staff besides the
monitoring data also of assigned and licensed
frequencies
• Leads to an efficient spectrum management
organisation

Situation today:
• Increasing usage of integrated spectrum
•
•
•
management systems;
Leading manufacturers of monitoring equipment
can provide the linking with spectrum
management systems;
Also for ITU software tool SMS4DC version 3 a
first linking will be realised;
More linking with other manufacturers are
foreseen
