Bluetooth and Bluetooth Low Energy (BLE) solutions encompass a wide range of products, from network processors that can be used to integrate BLE functionality into an existing product, to single-core wireless system-on-chip (SoC) application processors. By 2024, estimated annual shipments of Bluetooth® technology-enabled devices within the industrial sector are expected to exceed 335 million, according to the 2020 Bluetooth Market Update.
The Industrial Internet of Things (IIoT) covers a growing number of devices and machines within the industrial sectors that are equipped with sensors, connected to wireless networks, and can share data on their status and receive instructions. The gathered data allows companies to create more efficient business processes and reduce costs.
One of the key driving forces behind designing IIoT systems is Bluetooth® networking technology. Although its global awareness stemmed from consumer-oriented technology like headsets, wireless speakers and keyboards, the recent developments in Bluetooth® technology enable reliable and secure communication even in harsh conditions of industrial environments.
Bluetooth® Low Energy (LE) radio entered the market in 2011 as a very low-power connectivity solution for battery-operated applications supporting data rates up to 2 Mbps. Both Bluetooth® and Bluetooth® LE radio protocols operate in a 2.4 GHz ISM band.
