Localisation AoI, showcasing the impact—in terms of the PEB (in dB)—of a reflective RIS deployed close to the lower right corner of the investigated scene (green star) to assist a conventional downlink positioning system relying on 3 BSs (red triangles). Interestingly, the RIS enables localisation and, even significantly boosts, accuracy in subregions close to the RIS (resp. yellow and green areas), without degrading performance elsewhere (blue area)
