The aim is not to change regulations but to investigate potential problems when having all these applications implemented in the same car.

WGFM#87 (Jan./Feb. 2017) approved a revised explanatory paper for RLAN usage in vehicles. This is referenced in Rec. 70-03

WG FM#90 in February 2018 agreed to task the SRD/MG to consider RLAN operation in automotive vehicles within the range 5150 - 5250 MHz with the aim to amend the explanatory paper for RLAN usage in vehicles and to consider a power limit of up to 25 mW, which would provide consistency with the power level of RLAN operating under the regulation for non-specific SRDs in the 5.8 GHz band. This can imply triggering standardisation activities as well as considerations about the need to additions in the current regulations in a second step.

WG FM #91 (May 2018) approved a revision of the explanatory paper related to RLAN equipment using the 5 GHz bands in vehicles, including the usage under the non-specific SRD regulation. This follows the conclusion of WGFM that RLAN use inside cars (passenger cars, lorries, buses) in the band 5150-5250 MHz is allowed at a maximum e.i.r.p. of 25 mW as this power restriction meets the demand and results in at least an equivalent attenuation as foreseen for RLAN operation inside buildings and therefore the necessary attenuation to facilitate sharing is provided. In order to prevent that RLAN inside cars operating within these frequency ranges use higher emissions than a maximum e.i.r.p. of 25 mW, ETSI is proposed in a liaison statement from WG FM to consider a “in vehicle mode” is taken into account during the next revision of the EN 301 893. The revised explanatory paper for RLAN usage in cars will be referenced in ERC Recommendation 70-03 in the introduction as well as under ‘frequency issues’ in Annex 13 in relation to the entries for ECC Decision (04)08;
