The beacons are inexpensive, compact, and come with an adhesive sticker for easy attachment to assets. They can be placed almost anywhere and function even through metal, making them suitable for use with beds, pumps, ventilators, etc.
Each beacon continuously sends out its location and has a battery life of 2-3 years. The batteries are replaceable and cost very little.
Using standard Bluetooth technology (the same as in phones and earbuds), the beacons don't interfere with other devices or systems.
