The Micro-Beacon system consists of tiny (<10mm) battery-operated beacons and a network of one or more receivers. These beacons may be tagged onto high-value objects or assets that need to be monitored or tracked or may even act as standalone sensors. The beacons transmit RF packets over a distance of about 100m and a network of one or more receivers installed within a monitored area receives these transmissions and hand them off to a backend system for processing. This system enables various applications such as asset tracking, security tagging, remote monitoring, proximity detection and wireless sensor networks.
The beacons are self-contained units that are battery operated and may utilize energy harvesting methods. The RF transmissions use highly optimized packet formats based on IEEE 802.15.4 standard, allowing a high density of beacons in an area and very low power consumption. The receivers may be interconnected with WiFi or Ethernet to each other and to a backend system. Each packet received by the backend consists of the Beacon ID, Receiver ID and any other beacon data such as the status of sensors onboard the beacon. Using the network of receivers, proximity sensing and rough localization of the beacon position may be performed. The beacon hardware may also have various kinds of low-power sensors such as accelerometer, temperature, humidity, light, magnetic and movement sensors. The benefits include
The onboard micro-controller and variety of sensors on the beacon enable applications that are not possible through conventional passive tags.
With the growth in online shopping and home deliveries, the logistics and transport chain required for high-value items presents a prime opportunity. Increased monitoring and effective management of assets in commercial, service and hospitality industries can be enabled by this technology.
