  Reconfigurable Intelligent Surfaces (RIS) are currently considered for
adoption in future 6G stantards. ETSI and 3GPP have started feasibility and
performance investigations of such a technology. This work proposes an
analytical model to analyze RIS performance. It relies on a simple street model
where obstacles and mobile units are all aligned. RIS is positioned onto a
building parallel to the road. The coverage probability in presence of
obstacles and concurrent communications is then computed as a performance
criteria.
