Bluetooth Low Energy (BLE)

BLE is a wireless communication technology designed for low-power, short-range data transfer. It enables devices to stay connected for long periods while consuming very little energy.

Why it’s useful:

  • Ideal for battery-operated devices
  • Fast pairing and efficient communication
  • Common in IoT ecosystems and smart environments

Examples:

  • Fitness bands syncing health data to a phone
  • Smart home devices (locks, lights, sensors)
  • Hospital patient monitoring systems
  • Proximity beacons in malls for navigation or offers
