The Raspberry Pi 3 Model B is a compact, single-board computer featuring a 64-bit quad-core ARM Cortex-A53 processor, built-in Wi-Fi, and Bluetooth 4.1/BLE capabilities, making it a versatile and low-cost embedded computing platform. In WiFi and CSI sensing research, it serves as a practical data collection and processing node for tasks such as capturing Wi-Fi Probe Requests, Bluetooth Classic responses, and BLE advertisement frames for occupancy estimation, as well as implementing fingerprinting and trilateration algorithms for indoor localization within IoT deployments. Its integrated wireless radios, low power consumption, and affordability make it particularly well-suited for prototyping real-world sensing systems, and it is commonly distinguished from related variants such as the Raspberry Pi Zero W and Raspberry Pi 4 Model B by its balance of computational capability and hardware cost.
