Beacons

Transmit RF signals, usually Bluetooth Low Power (BLE), RFID or Wi Fi, to provide push information, location based services, or product information.

Beacons transmit in 4 ranges:

- Immediate=inches

- Near=3 to 8 feet

- Far=30 to 90 feet

- Long Range=100 feet to half a mile

New developments in power and chip technology promise to increase the range.
