Asset Tracking
Industry leading asset tracking solutions enabled by infineon wireless technology
In recent years, Asset Tracking market keeps rapidly growing along with the wireless technologies development, enabled by the advanced location technologies on both SRW (short range wireless) and WAN (wide area networks). However, BLE is the dominator at this moment because of the low cost and low power advantages in SRW deployments. The total market volume is still ramping up in some vertical markets such as manufacturing, logistics, warehouse, supply chain, smart offices and healthcare etc, and expected to reach 800Mu annual shipment in 2028, with ~30% CAGR.
Most of the existing asset tracking systems are deployed by BLE Beacon technology, to address the entry-level location requirement. Generally, some anchors are necessary as fixed locators, and continuously report to server all tags they can hear by the received signal strength (RSSI) from each tag in terms of Beacon protocols, such as iBeacon, EddyStone, AltBeacon.
In the angle of arrival (AoA) method, the device to which direction is being determined,such as a tag in an Real-Time Location System(RTLS) solution, transmits a special direction finding signal using a single antenna. The receiving device, such as an anchor in that same RTLS solution,has multiple antenna arranged in an array. As the transmitted signal crosses the array, the receiving device sees a signal phase difference due to the difference in distance from each of the antenna in its array to the transmitting antenna. The receiving device takes IQ samples of the signal while switching between the active antenna in the array. Based on the IQ sample data, the receiving device can calculate the relative signal direction.
In the angle of departure (AoD) method, the device to which direction is being determined, such as an anchor in a RTLS , transmits a special signal using multiple antenna arranged in an array. The receiving device, such as a mobile phone/tag in that same RTLS, has a single antenna. As the multiple signals from the transmitting device cross the antenna in the receiving device, the receiving device takes IQ samples. Based on the IQ sample data, the receiving device can calculate the relative signal direction. This method is intended for use in indoor positioning solutions, such as way-finding.
