A Badge Bluetooth Beacon, also known as a BLE (Bluetooth Low Energy) beacon, is a small wireless device that constantly emits radio signals to nearby smartphones and tablets. These signals contain a small amount of data and are broadcast at regular intervals. The primary purpose of a Bluetooth beacon is to provide proximity-based interactions with mobile apps on compatible devices.
Here's how Bluetooth beacons work:
- Signal Broadcasting: A Bluetooth Beacon continuously sends out radio signals in its vicinity, typically covering a range of up to 70 meters without obstructions.
- Bluetooth Low Energy (BLE) Technology: Bluetooth beacons utilize Bluetooth Low Energy, a power-efficient version of the standard Bluetooth protocol. BLE allows beacons to consume very little power while transmitting data.
- Device Detection: Mobile apps on smartphones and tablets can listen for these signals and detect when they come into range of a relevant beacon.
- Triggering Actions: When a compatible mobile device picks up the signal from a nearby beacon, it can trigger predefined actions in the corresponding mobile app. These actions can include displaying notifications, providing location-based information, or interacting with other services.
- Range Variation: The signal range of Bluetooth Beacons can vary depending on the presence of obstructions. Thick walls made of metal or brick can reduce the range, while open spaces allow for a longer reach. Bluetooth beacons can also define different ranges of distance, such as far, near, and immediate, enabling apps to respond differently based on the proximity to the beacon.
- Compatibility: Modern smartphones, including iPhones, Android devices, and Windows phones, can support Bluetooth Low Energy. However, the behavior of beacon detection and interaction may differ slightly between platforms. For instance, on iOS devices, the phone can constantly scan for BLE devices and wake up relevant apps when they come within range, even if the apps are closed. On Android devices, apps must scan for BLE devices themselves, which could potentially use more battery.
- Beacon Internal Structure: Bluetooth Beacons are small, wireless devices that typically contain a CPU, radio, and batteries. They come in various shapes and sizes, and their internal components are designed for simplicity and efficiency.
