Basic standard for the calculation and measurement of electromagnetic field strength and SAR related to human exposure from radio base stations and fixed terminal stations for wireless telecommunication systems (110 MHz - 40 GHz)

This basic standard applies to radio base stations and fixed terminal stations for wireless telecommunication systems as defined in Clause 4, operating in the frequency range 110 MHz to 40 GHz. The objective of the standard is to specify, for such equipment, the method for assessment of compliance distances according to the basic restrictions (directly or indirectly via compliance with reference levels) related to human exposure to radio frequency electromagnetic fields.

Grundnorm für die Berechnung und Messung der elektromagnetischen Feldstärke und SAR in Bezug auf die Sicherheit von Personen in elektromagnetischen Feldern von Mobilfunk-Basisstationen und stationären Teilnehmergeräten von schnurlosen Telekommunikationsanlagen (110 MHz bis 40 GHz)

Norme de base pour le calcul et la mesure des champs électromagnétiques et SAR associés à l'exposition des personnes provenant des stations de base radio et des stations terminales fixes pour les systèmes de radiotélécommunications (110 MHz - 40 GHz)

Osnovni standard za izračunavanje in merjenje moči elektromagnetnega polja in SAR v povezavi z izpostavljenostjo ljudi sevanjem zaradi radijskih baznih postaj in fiksnih terminalskih postaj za brezžične telekomunikacijske sisteme (110 MHz - 40 GHz)

Ta osnovni standard velja za radijske bazne postaje in fiksne terminalske postaje za brezžične telekomunikacijske sisteme, kot je določeno v Klavzuli 4, ki delujejo v frekvenčnem razponu od 100 MHz do 40 GHz. Namen tega standarda je za takšno opremo določiti metodo za ocenjevanje dogovorjene razdalje v skladu z osnovnimi omejitvami (neposredno ali posredno s skladnostjo z referenčnimi stopnjami), povezanimi s človeško izpostavljenostjo elektromagnetnim poljem radijske frekvence.

Corrigendum to EN 50383:2010 English version ___________ Due to a mistake in the numbering, the whole Clause 6 needs to be renumbered. Please note that the content of Clause 6 has not been modified. Replace the entire Clause 6 by the following: 6 Electromagnetic field measurement 6.1 Introduction This section describes the measurement procedures that may be used to assess, at points of investigation, the electromagnetic field components (E and H and therefore the power density) radiated by antennas. The field measurements can be obtained either by surface or volume scanning.
The methods used are to measure directly or indirectly the E-field or H-field strength, deduce the field distribution for a given input power and frequency. 6.2 Surface scanning method 6.2.1 Introduction
Methods to perform surface scanning could be, but are not limited to, far-field, compact range, and planar, cylindrical or spherical near-field as long as the methodology is accurately defined and the uncertainty criteria (Annexes B and E) are fulfilled.
6.2.2 Spherical scanning method Measurements of electric field amplitude, phase and polarisation are made at sufficient points on the surface of a sphere surrounding the EUT to establish the parameters to model a set of isotropic sources on that surface that will produce at the point of investigation the same field as the EUT. To make this valid, the scanned spherical surface shall contain all the relevant energy that is radiated from the EUT. The parameters of this set of isotropic-radiators are then used to calculate the field at the points of investigation required in order to establish the compliance boundary.
The principle steps are summarised in Figure 1. SIST EN 50383:2010/AC:2013

(6.2.3)
Figure 1 – Outline of the surface scanning methodology 6.2.2.1 Measurement equipment 6.2.2.1.1 General description The surface scanning consists of an Equipment Under Test (EUT) mounted on an azimuthal positioner and the probe(s) mounted on a support structure at distance Rmes from the EUT. This method requires the ability to measure the phase of the signal. Detection shall consist of either one probe moved mechanically along the structure or one probe array switched electronically in order to perform an angular elevation scan of the electromagnetic fields.
Alternatively, the EUT can be moved to different elevation angles by means of an additional elevation positioner. The near-field antenna measurement system shall be configured according to Figure 2. SIST EN 50383:2010/AC:2013
