With a central WLC managing one AP per store, which technique provides per-store user analytics (presence counts)?

Presence analytics, often called location analytics or Wi-Fi analytics, is the correct technique. It leverages the Wi-Fi signals from devices (like smartphones) associated with or detected by the Access Points (APs) to count the number of unique devices within a specific area (in this case, each store). This provides real-time or historical data on foot traffic and occupancy. Angle of Arrival (AoA) is a method used for more precise device location, often in conjunction with other techniques, but it's not the primary method for simple presence counting. Trilateration is a geometric method for determining a position based on distances from three known points, offering higher precision than simple presence but requiring more complex setup. Hyperlocation is an advanced Cisco technology that combines multiple location techniques (like AoA, AoD, and RSSI) for highly accurate indoor positioning, which is overkill and not the direct answer for basic presence counts.
