The Evolution of Bluetooth Low Energy 

Bluetooth Low Energy's origins trace back to 2006 when Nokia, in partnership with Logitech, developed a low-power wireless technology called Wibree. In 2007, the Bluetooth Special Interest Group (SIG) incorporated Wibree into the Bluetooth standard, officially launching Bluetooth Low Energy in 2010 as part of the Bluetooth 4.0 specification. Unlike classic Bluetooth, which supports high-bandwidth applications, Bluetooth Low Energy was designed for low-speed data transmission, ideal for IoT devices that require minimal power and extended battery life. 

Bluetooth Low Energy vs. Classic Bluetooth 

While both Bluetooth Low Energy and classic Bluetooth operate on the 2.4 GHz radio frequency band, they serve different purposes. Bluetooth Low Energy is not an upgrade to classic Bluetooth; it is an entirely new technology. Classic Bluetooth is often used for high-bandwidth applications such as audio streaming, while Bluetooth Low Energy is optimized for applications that require less power, such as sensors and wearables. BLE devices are classified as central or peripheral, with central devices handling more complex tasks and peripheral devices conserving power by relying on the central device for processing.

Key Technical Advantages of Bluetooth Low Energy 

Bluetooth Low Energy offers several technical advantages that make it an attractive choice for businesses deploying IoT solutions: 

• Low Power Consumption: Bluetooth Low Energy devices consume minimal power in idle mode, allowing them to operate for months or even years on a standard coin-cell battery. This low power requirement results in lower operational costs, making BLE ideal for large-scale deployments in industries like healthcare and logistics. 

• Frequency Hopping: BLE uses frequency hopping, operating on 40 channels within the 2.4 GHz band. This technique reduces interference from other wireless devices, ensuring stable and reliable communication in congested environments. 

• Simplified Modulation: Bluetooth Low Energy employs a simpler modulation scheme compared to classic Bluetooth, reducing complexity and production costs for manufacturers. This simplicity is a key factor in the adoption of BLE for commercial IoT solutions. 

• Scalability: Bluetooth Low Energy networks can support a large number of devices, making BLE ideal for enterprise-scale IoT applications. Its widespread adoption ensures interoperability with billions of devices, facilitating seamless integration into existing infrastructure.
