This technology reaches its limits when it comes to bigger data sizes, as it is optimised for small data transmissions. These networks enable true remote data collection accessible from anywhere via a cloud system. This challenge is addressed by technologies using long-range radio waves, such as a LPWAN (low powered wide-area network).

Thus, it enables a wireless connection but without a remote data collection as the sender and receiver need to be close to each other. The distance is limited from two to maximal 8-meter range.

However, there are is a main challenges for Bluetooth transmissions:Īlthough Bluetooth replaces cables and enables wireless data transfer, it is still limited to short distances. The name Bluetooth goes back to a Danish King, based on the analogy to unite devices the way Harald Bluetooth united tribes of Denmark into a single kingdom.Īlso in the industry, Bluetooth is used in several solutions, in particular for measuring devices and with its low power consumption, it is a popular technology. Short-link radio technology, later named Bluetooth, enables wireless connection over short distances using short-wavelength. It is still commonly used in headphones, wireless keyboards, free-hand set in cars and other electronics. Bluetooth was invented in Sweden in 1989 to enable wireless data transmission.
