RF Safety

Wavecontrol LogoWavecontrol

From 1997 Wavecontrol has been involved in the EMC (Electromagnetic Compatibility) designing, developing, manufacturing and distribution of instrumentation and components for commercial, government and defence purposes.

Wavecontrol offers a comprehensive product line in different areas:
SMP, Portable Monitoring System

SMPThe SMP Portable Electromagnetic Field Monitoring System can measure electromagnetic field levels generated by any source within the frequency range of the probe attached to the system.

For example it can measure fields generated by different sources such as mobile telephone base stations, radio and television transmitters and repeaters, DECT systems, Wi-Fi systems, etc.

Those measurements can be made quickly and easily anywhere because the SMP is portable and simple to handle and use, the data is stored in memory and can easily be downloaded to a computer via a USB port for later processing.


The SMP can sample the field level continuously and store that data automatically in its built-in memory at user-configured intervals with a capacity of up to 62400 samples (without GPS data) Or 27300 samples (with GPS data).

SMP & AntennaThe SMP is designed for simple and intuitive operation with 2 basic functions:
  • Instant and averaged field measurement
  • storage of field measurements in memory
The SMP integrates a new multi-measurement system that allows performing instant measurements of the total field level, Ex, Ey and Ez separately, continuous measurements, arithmetic averaging, minimum and maximum values, and normative measurements.

The internal configurable alarm generates an audible signal (warning) when the measured level exceeds the adjustable threshold.

The SMP can be equipped with an internal GPS module so the measured data can be associated to its position and displayed on a GIS application.

Different kind of field probes are available and can be easily changed thanks to its probe automatic recognition system.

The SMP contains a rechargeable Li-ion battery allowing the apparatus to run for over 10 hours.

RFMS, Radio Frequency Monitoring System

RFMS SystemThe effect of Electromagnetic Radiation on the general public is becoming a concern as the number of sources increases dramatically. Of all the types of Radio frequency equipment designed for communication applications, the greatest concern is directed at Mobile Telephone Base Stations.

Recent legislation limiting the maximum levels of electromagnetic radiation permitted from these installations has been introduced to protect the public, but compliance testing is often performed infrequently and over a short period of time.

RFMS is a state-of-the-art measuring system manufactured and developed by Wavecontrol an engineering company working in the field of electromagnetic compatibility and RF & Microwave testing.

The RFMS can be installed as a single monitoring station, or multiple RFMS units can be configured to provide, for example, a city wide monitoring system. All Monitoring Stations carry out continuous electromagnetic field measurements (24/365) providing averages of the obtained values as specified in International standard requirements. All measurement data obtained is sent to the Control Center for processing.


The RFMS is an ideal system for those responsible for base station reliability and performance.

Continuous verification that the electromagnetic radiation produced by the base station is below recommended international limits maintains public confidence.

The RFMS is also ideal for those responsible for ensuring either employees or members of the public are not subjected to unsafe levels of electromagnetic radiation. Locations such as public buildings, hospitals and schools can benefit from knowing the output from sources close to their facilities.

> Measurement range: 0.06 - 60 V/m
> Averaging of data values
> Data Transfer

The hardware system fundamentally consists of a reception block and electromagnetic field measurement, a management block averaging and recording the data, and a communications component that is in charge of transferring the data to the Control Centre.

The hardware system also has a programmable observational system that activates alarms in the case a field detected has a higher level than expected.


The two fundamental applications of the SMRF are:
  • Control of an emission source:
      In this case the source to be controlled is Mobile Phone Base Stations. The installation of the Remote Monitoring Stations can be set in several functional positions depending on the measurement function or the specific control that we want to perform regarding the Telephone Base Station. It is recommended to seek points of maximum radiation from the Base Station, thus enabling one to assure that the remaining points will remain below the controlled and registered values.
  • Control of a Sensitive Site:
      In this case the concern is not so much as to where the radiation comes from, but the level itself of total radiation in an especially sensitive location such as a school, hospital, or buildings near Telephone Base Stations etc. The placement therefore of the Remote Monitoring Stations should be undertaken at the point where the levels that we wish to control are.
