RF Monitoring
Wavecontrol Logo
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:
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.

RFMS System installed on site> Measurements of GSM900, GSM1800 and UMTS
> 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.
