Abstract	Surveillance and crowd monitoring techniques are useful tools in smart cities and smart campuses, allowing for patrons to be tracked and for security to be enforced. WiFi sensing is emerging as a privacy sensitive alternative to Closed-Circuit Television (CCTV) cameras, with the additional benefit of deployability using low-cost Internet of Things (IoT) devices. Currently, there is uncertainty around the viability of WiFi based crowd monitoring in outdoor spaces, due to the absence of multipath. Hence, in this paper we provide an experimental testbed and validation of WiFi-based occupancy monitoring using Channel State Information (CSI) in uncontrolled outdoor environments such as campus thoroughfares, achieving an accuracy up to 80%. In the final conference paper we present experiments which demonstrate a trend correlating the openness of an environment with the achievable monitoring accuracy. These novel insights provide implementation guidelines as WiFi sensing is deployed in real world outdoor settings. © 2023 IEEE.
