Meraki presence analytics API লঞ্চ করেছে

The Cisco Meraki Presence API (now part of the Scanning API) is a real-time location telemetry feed provided by Cisco Meraki cloud-managed access points. The AP radios passively detect 802.11 probe requests and Bluetooth Low Energy (BLE) advertisements transmitted by nearby smartphones and client devices. The Meraki cloud calculates signal strength (RSSI), estimates spatial coordinates, and streams batched JSON payloads via HTTPS POST webhooks to receiver platforms like Purple.

Scanning API v3 supersedes Presence API v2 by delivering unified telemetry for both WiFi clients and BLE beacons in a single webhook stream. Version 3 includes high-resolution floorplan coordinates (X/Y position and GPS latitude/longitude), confidence uncertainty radii, access point radio band tags, and support for IPv6 client addresses, providing higher location precision across enterprise estates.

When a device transmits probe requests, multiple Meraki access points record the Received Signal Strength Indicator (RSSI) and timestamps. The Meraki cloud location engine uses multi-point trilateration to estimate the physical coordinates of the device. Dwell time is measured by calculating the elapsed time between the first detected probe frame and the last observed frame within a defined venue boundary.

Modern mobile operating systems use rotating, randomized MAC addresses during unassociated probe scans. Purple's analytics engine filters short-lived randomized probe bursts to ensure accurate aggregate footfall counts, and links returning visitors securely when they authenticate through the Purple captive portal using privacy-compliant one-way cryptographic hashing.

Meraki access points upload small JSON payloads to the Meraki cloud, which aggregates and delivers HTTPS POST requests to the Purple webhook receiver every 30 to 60 seconds. A typical 20-AP venue generates approximately 50 to 150 KB of webhook data per minute, imposing zero backhaul overhead on local venue internet links.

Presence analytics captures 100% of nearby radio-emitting devices to measure total passerby traffic, exterior footfall, and window conversion rates. When visitors log into Purple Guest WiFi via the captive portal, their demographic data (age group, gender, marketing consent) is correlated with aggregate spatial trends to provide statistically significant customer demographic insights.
