BLE TECHNOLOGY
Bluetooth Low Energy (BLE) technology works at 2.4Ghz frequencies and is based on the Bluetooth standard, from version 4.0+.Thanks to a special communication protocol, the low power consumption has allowed the design of beacon tags with a battery life up to 4/5 years, that is able to send an electromagnetic signal even at distances over 200mt. Intelligent sensors such as accelerometer and temperature/humidity can be added to complete the proposal. BLE technology can be considered as active RFID technology, but with the great advantage of being completely standard and working with almost any smartphone available today.
