In access control, the devices are usually based on Bluetooth Low Energy (BLE) which offers high energy efficiency and performance.
It divides transmitted data into packets and transmits each packet on one of 79 designated Bluetooth channels. It utilises UHF radio waves in the ranges between 2.402 GHz and 2.480 GHz.īluetooth utilises a radio technology called frequency-hopping spread spectrum. The key differences between NFC and Bluetoothīluetooth is a wireless technology that enables data exchange between fixed and mobile devices over short distances.What Near-Field Communication (NFC) is and how it works.What Bluetooth technology is and how it works.However, that's where the similarity ends as, beyond that, Bluetooth and NFC are quite different. NFC and Bluetooth technologies are the biggest players in this field, with what can seem like similar features.īoth technologies enable the connection between two devices over short ranges, providing a reliable communication path for devices to transfer the data. More and more wireless technologies are appearing in the security arena, offering solutions to different applications and needs. Nowadays numerous technological trends are fuelling a digital revolution in various industries, and access control is no exception.
