Bluetooth (BT) has been with us for over 20 years now. It’s become the largest volume wireless technology in use today, with industrial IoT and widespread consumer adoption keeping BT ahead of all other wireless standards. Research indicates that 4 billion Bluetooth units were shipped in 2019, and forecasts reveal that 5.4 billion units are expected to ship in 2023—an increase of 26%.
BT’s popularity is due to its reliability, flexibility, and the fact that it’s so easy to use. On top of that, the Bluetooth Special Interest Group (SIG) continues to develop, improve, and fine-tune the standard, making it even better.
