Bluetooth 2 Bluetooth is a wireless communication technology in the UHF-range from 2.402-2.480 GHz. The IEEE standardized Bluetooth in IEEE 802.15.1, but no longer maintains the standard. Instead, the Bluetooth SIG oversees development, specification, qualification program and protects the trademarks. An important boost came with the introduction of Bluetooth Low Energy (BLE) as a subset of the Bluetooth v4.0 core specification. The entirely new protocol stack for rapid build-up of simple links is aimed at very low power coin-cell applications such as advertising beacons for indoor navigation and asset tracking.

LOYTEC multisensors and LOYTEC controllers with Bluetooth interface use BLE for asset tracking. In addition, LOYTEC multisensors are able to advertise either standard beacons with configurable identifier like iBeacon or EddyStone-UID which allows them to be perfectly integrated in indoor navigation systems. The L-WEB beacon enables secure room operation using the LWEB-App, as it restricts access to LWEB-900 functions to the close vicinity of the L-WEB beacon.
