Concerning Bluetooth® Wireless Technology
Bluetooth wireless technology has been developed by the Bluetooth SIG consortium and allows transmissions up to 100 m depending on the power used, it is not limited to line-of-sight and uses very little energy.
Advantages of Bluetooth wireless technology
Guarantee of data transmission by acknowledgement system
Robustness linked to frequency hopping technology and error correcting codes
Low energy consumption
Why use Bluetooth in our products
One of the main advantages of Bluetooth technology is the fact that it is very standardized which guarantees a high level of interoperability.Two Bluetooth devices communicating together with the same "profile" will understand each other without prior configuration, even if the devices are of different makes.
When compared with 433MHz, or even WiFi type systems, Bluetooth is more robust.
