Technically, BLE-enabled devices can sense the strength of the signal between the sender and the receiver. However, Bluetooth LE has the same advantage of being present on the perhaps most ubiquitous consumer device: the smartphone, which is almost always on your person.

Smart home: Manufacturers of various smart home automation and devices use a number of different technologies in their products.

This makes it realistic to rely on ubiquitous BLE-enabled consumer devices, such as smartphones, for various security applications. BLE uses the AES-128 encrypted data transfer channel and provides for key management across multiple devices.

Security: While this may not be intuitive, Bluetooth LE makes it possible and even practical to use your smartphone as your car key or even house key.

Manufacturers of sports apparel, footwear and gear are extremely interested in BLE and will likely continue to expand their ranges of BLE-enabled products.

Fitness: Today the market is being almost flooded with fitness gear and accessories featuring BLE such as heart rate monitors, pedometers, and even running shoes.

These devices have battery lives of months and even years.

Most of today’s medical devices, such as blood pressure of heart rate monitors, use Bluetooth LE for data transmission. Healthcare: Bluetooth LE is already widely used in healthcare.BLE makes all sort of cool things possible or easier. In practice, the fastest Bluetooth Classic can send data is at the rate of 1,200 kb/sec, handily beating the measly 50 kb/sec achieved with Low Energy. However, as far as data transmission rates are concerned, we quickly see the trade-off: the fastest theoretical transmission rate for Classic is 2,178 kb/sec, almost an order of magnitude faster tha BLE (303 kb/sec). Bluetooth Low Energy. BLE requires 3.8 μJ of energy to send an 8-byte data packet versus 21.1 μJ for Classic - a huge advantage. Let’s make a comparison across several technical characteristics of Classic Bluetooth vs.

The advent of Bluetooth Low Energy has made it possible to create devices and accessories with great battery life. In practice what this means for designers and software engineers is having to plan for faster data exchange, lower volume of data sent and received, and coming up with a completely new architecture (classic Bluetooth and Bluetooth LE are not compatible).
