Bluetooth is a radio technology for wireless data transmission over short distances, which was developed in the 1990s. With this network technology, data can be exchanged between computers and/or smartphones, but also everyday devices such as wireless speakers, keyboards or mice can be connected. Data transfer rates are usually lower than via a USB or network cable, which is why Bluetooth is unsuitable for sending large amounts of data.
In addition to the classic Bluetooth, another radio technology has been developed: Bluetooth Low Energy (Bluetooth LE, BLE), also called Bluetooth Smart. It has the same range as the classic Bluetooth -– between 10 and 30 meters -– and consumes even less energy. Walls and metal elements significantly restrict reception, which is why the range varies. However, other electrical devices or radio networks rarely have negative effects on this.
Indoor Navigation & Positioning using Bluetooth technology and Beacons
This network technology is also used particularly frequently for indoor navigation and indoor positioning. For this purpose, Beacons are required, which are also based on a transmitter-receiver principle. Bluetooth Low Energy (BLE) technology enables battery operation for two to eight years without the need for external power supply. Beacons can also be connected to the mains supply or use the power supply of lamps. Due to the industry standard Bluetooth Smart, the solutions of by infsoft are compatible with beacons of all manufacturers
Examples of Use: Indoor Navigation in Railway Stations with Bluetooth Beacons
