shield
The inf rare dre flective windshield is coated and
pr eve nts an excessive build-up of heat in the
ve hicle interior.
The coating shields theve hicle interior against
ra dio waves up into the gigahertz range.
Ra dio-cont rolled equipment, such as toll sys‐
te ms, can only be mounted on areas of the wind‐
shield which are permeable toradio wav es1.
