Introduction

The IPD24 System is an indoor positioning product that uses wireless technologies like Bluetooth, Wi-Fi, LoRa, and RFID to determine location by measuring the ranging information from LoRa and the signal strength (RSSI). The system is designed with a user-friendly power setup, though it isn’t optimized for space or power consumption. All devices are powered by 110Vac using either built-in power supply units (PSUs) or external AC adapters.

Key Features and Technology

Technology

The IPD24 System is an indoor positioning product that uses several wireless technologies to determine location by measuring

• Round Trip Time-of-Flight (RTToF). LoRa can get ranging information by measuring the Round Trip Time-of-Flight (RTToF) of a packet exchange between devices

• signal strength feedback (RSSI). The system’s core features and functions are based on its use of these technologies: Bluetooth, Wi-Fi, LoRa, and RFID.

• AoA - Angole of Arrival/Departure. The system is also incorporate antenna arrays designed to capture signal for objects approaching/departure angle from the array surface.

• Computer Vision - The system uses multiple camera feeds for remote management of the testing environment. OpenCV based detection methods are developed to assist the estimation of hardware wherabout.

The system incorporates LoRa technology, specifically the AS923 / US915 profile, which operates at a radio frequency of 915-928MHz. The hardware for this is the SX1280. LoRa is designed for long-range, low-power communication, making it suitable for applications where devices need to send small amounts of data over large distances with minimal battery consumption.

Features

Then, the system’s primary function includes

• Indoor location tracking. It achieves this by utilizing multiple wireless technologies to get RSSI values.

• Rover measures ranging info from each IPD24 Box.

• RFID tags are also used as location tags to identify known spots in an indoor space.
