Appendix F : MOTOTRBO Repeater –
EME ASSESSMENT
NOTICE: The example given in this Appendix applies for a UHF band system. For different
frequency bands, applicable band-specific parameters should be employed to carry out the
computations yielding band-specific compliance boundaries.
Executive Summary
The Electromagnetic Energy (EME) compliance boundaries in a typical system configuration of the
Motorola MOTOTRBO SLR 5000 Series Repeater described in the following are derived.
Compliance is established with respect to the applicable limits defined in the ICNIRP guidelines [1], the
United States regulations [2]-[3], and in the CENELEC Standards EN50384:2002 [5] and
EN50385:2002 [6]. These standards and regulations apply to occupational and general public EME
exposure.
The assessment was carried out using a computational method described in the CENELEC Standard
EN50383:2010 [4], which is referenced by the EN50385:2002, and this report has been drafted in
accordance with its requirements. Thus the assessment and report address the European Radio and
Telecommunications Terminal Equipment (R&TTE) Directive requirements concerning EME exposure.
The following table provides the compliance distances for general public and occupational-type
exposure, for the UHF frequency band, antenna, and parameters considered in this analysis, based on
a typical system configuration:

Compliance distances Antenna front (Andrew mod.
DB408)
Ground level (20 m below an-
tenna)
General public exposure 6.9 m Always compliant
Occupational-type exposure 2.15 m Always compliant
Exposure Prediction Model
Exposure in Front of the Antenna
The cylindrical-wave model defined in Clause 8.3.4 of the EN50383:2010 standard is applied to
determine the compliance boundaries for workers and general public for a typical system configuration
of the MOTOTRBO SLR 5000 Series Repeater.
