EVS-EN 303 132 V1.1.1:2017

The present document lays down the minimum requirements for low power maritime personal locating beacons
employing DSC signalling according to ETSI EN 300 338-6 [1], on the VHF maritime mobile frequency band channel 70.
Maritime personal locating beacons employing DSC signalling also include AIS with an integrated GNSS receiver to
provide the locating function according to ETSI EN 303 098 [2]. The present document incorporates the relevant
provisions of the International Telecommunication Union (ITU) radio regulations [i.4] included in Recommendation
ITU-R M.493-14 [3]. The present document does not cover requirements for the integrated GNSS receiver providing the
locating function.
LBT (Listen Before Talk) techniques are employed to improve spectrum efficiency.
For this application, both the radiated power and the length of time of operation are limited to enable the equipment to
be sufficiently small and light to be worn comfortably at all times and to limit the operating range to a local area.
The present document also specifies technical characteristics, methods of measurement and required test results.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] under the
conditions identified in annex A.
