Course: Spectrum Monitoring, Measurements and Techniques
Spectrum Monitoring is, besides Spectrum Planning and Licensing, one of the key elements in spectrum management process. Monitoring is not only solving interference problems but also tasked with for instance:
Checking license parameters, e.g. field strength and bandwidth (remote inspection)
Comparing predicted and measured values
Identifying illegal use
Supporting preparation for WRC
Quick overview of the spectrum
Refarming
Detecting White Spaces, etc
Frequency Planning and Licensing provide the theoretical (calculated) occupancy. Monitoring provides the real (automatically or manual measured) occupancy. The smaller the difference between theoretical and real occupancy, the better the quality of the overall spectrum management process.
The Spectrum Monitoring Technology Advisors (SMTA) spectrum monitoring learning course is based on the latest ITU-R and CEPT Recommendations, Reports and Handbooks and gives an introduction into the most common spectrum monitoring measurement techniques. All teachers are experienced monitoring engineers, have also fulfilled jobs in the management of the monitoring department and participated in ITU-R Study group 1 as well as in CEPT working groups and project teams.
Currently SMTA offers two course delivery models depending on your specific requirements:

Training Module T5: Simple Frequency Channel Occupancy Measurements
This module gives general information on most types of Frequency Occupancy Measurements (FCO), not to be confused with Frequency Band Occupancy measurements. It contains information from ITU-R SM.1880, the old ITU-R SM.1536 and Handbooks 2002 and 2010. In many countries the measurement principles are more or less the same, however, the way of presenting results is often very different. This part ends with a lot of real-life examples showing how channel occupancy is presented in different countries.

Reasons for FCO
Important parameters:
- Threshold level, dynamic, pre-defined

Training Module T6: Spectrum Control using Automatic FBO Measurements
Frequency Band Occupancy measurements can relatively easy and cheap be performed at monitoring stations. Let a receiver or spectrum analyzer run automatically according to a pre defined schedule, for instance every 24 hours a certain frequency band. By doing this a lot of information will be available on signal levels, occupancy etc. By repeating such measurements regularly it makes it possible to determine historical trends on spectrum usage. Developments: daily measurements 20 MHz - 6 GHz.

Training Module T7: Frequency Channel Occupancy Measurements
Tests show that an increase in re-visiting time to a certain level hardly influences the accuracy. This means that by increasing the number of channels and with relatively simple equipment monitoring can provide frequency channel occupancy information on a lot of channels. The ITU-R SM.1809 frequency band occupancy measurements can be applied, not only displaying results of frequency band measurements, but also the channel occupancy can be retrieved automatically very easily. Plots show occupancy caused by different users on one channel.

Training Module T9: Modern or Smart Monitoring Process (R.A.A.P.)
Monitoring is more than performing measurements, manually or automatically. Smart Monitoring offers a modern tool for collecting facts. Therefore it is important that monitoring is accepted as a vital part in the process of Spectrum Management and could for instance be divided in 4 steps: 1) Recording of the spectrum, 2) Archiving the data, 3) Analysing the information, and 4) Presentation of the results (e.g. on a website).

Training Module T11: Automatic Detection of Illegal (Broadcast) Stations
Exceeding of permitted power can easily be determined by automatic comparison of predicted and measured values. In addition to that, it is possible to detect illegal stations for instance in the FMBC band. Spectrum Monitoring Technology Advisors developed software for the entire range from 87.5 to 108 MHz. The in Matlab written software is based on the difference in received level during the day.

FM broadcasting is still very popular and it will remain for a number of years to come. The FMBC signal is rather complex. In this module a lot of techniques from previous modules are applied, such as smart and delta monitoring, comparing automatically measured and predicted field strength etc. Also frequency band occupancy measurements are used to collect data and present detailed information on FMBC. Furthermore, the baseband signal is studied and, for instance, the results from audio processing on the spectrum shape. This module contains a lot of examples of real-life measurements.

Training Module T15: WiFi, RLANs, etc. in 700 MHz and 2.4/5.8/60 GHz
The band 2400 - 2483.5 MHz is allocated to ISM but also a lot of other users are active in this frequency band. WiFi RLANs cause rather high occupancy in this frequency band. In most countries these RLANs are license exempt. RLANs however also have to fulfill certain conditions. In a lot of countries there are serious problems with these systems. The 5 GHz RLANs are becoming more and more popular because the 5 GHz band is not as heavily occupied as the 2.4 GHz band. A lot of new IEEE 802.11 standards for frequency ranges up to 60 GHz were developed recently. Manufactures are working on new RLANs integrated with 3G and 4G. About 75% of all mobile data traffic is running via WiFi. It is considered as a possible "offload" from 3G/4G traffic. That's why we see a fast development in new WiFi systems and used frequency ranges. There are also developments in systems like Bluetooth, Zigbee etc.

Training Module T20: Digital Broadcasting Systems
In all frequency ranges new digital broadcasting systems gradually replace analogue systems. In the MW and HF frequency range DRM is not very successful so far. DAB is available in a number of countries and DTT is already on air in a lot of countries and in the near future all analogue systems will be replaced by DTT systems, such as DVB-T and DVB-T2. The big difference in protection ratio between analogue and DVB-T explains an advantage to the transition.

Training Module T27: The Internet of Things (IoT/M2M)
The term IoT encompasses everything connected to the internet, but it is increasingly being used to define objects that "talk" to each other. Simply, the Internet of Things is made up of devices -from simple sensors to smartphones and wearables- connected together. By combining these connected devices with automated systems, it is possible to "gather information, analyse it and create an action" to help someone with a particular task, or learn from a process.

Training Module T28: Mobile Data Collection (MDC)
There are several methods to conduct measurements while driving a (monitoring) vehicle. Using Rec. ITU-R SM1708 is one of them. An other method, which is described in this module, is to equip several (20?) monitoring and other vehicles with equipment which is continuous measuring a certain frequency range, e.g. 20 MHz - 6 GHz. It starts automatically as soon as the vehicle starts to drive and ends when the vehicle stops. The results are automatically send to a central point (monitoring station) and will be processed automatically. It enables monitoring services to collect and display a lot of spectrum occupancy information with very limited human labor.
