Supercharging Beacons with Bluetooth 5.0 on blog
Bluetooth Low Energy (BLE) beacons have been a leading technology choice for proximity-aware applications in the market for several years. With its low power and simplicity, BLE has been adopted in a wide range of location-based services in smartphone apps and battery-powered beacons. When Bluetooth 5.0 was introduced, several major enhancements for BLE such as new PHY layers and Advertising Extensions have enabled second-generation beacons with fuller, richer content.
Beacon Basics A beacon is a small, inexpensive wireless device, often battery-powered, that uses BLE to advertise its presence. Think of a RF version of a lighthouse, which repeatedly broadcasts an identifier that is recognized by other devices within its range. Beacons do not directly provide information about their exact physical location, instead relying on a receiving device to be aware it is near the beacon. Because of their proximity awareness features, beacons are commonly used in retail and commercial businesses where proximity awareness can improve customer shopping experiences in POS systems, loyalty apps, and inventory.
Beaconing with Bluetooth 4.X BLE in version 4.x defines forty 2MHz wide channels in the 2.4-2.5 GHz ISM band. Three channels are reserved for advertising and the other 37 are data channels. Both advertising packets and data packets use the same format with a variable size payload and are only distinguished by the channel being used. Beacons based on Bluetooth 4.x are extremely power efficient as their payload size is restricted to a maximum 31-bytes of data. When more flexibility in payload and range is desired, the newly enhanced Bluetooth 5.0 beacon provides additional channel selections all while remaining compatible with the older BLE 4.x version.
Bluetooth 5.0 Enhancements With Bluetooth 5.0, new enhancements to the Low Energy standard, radio, channel selection, power, and advertising extensions were added. All of the following elements are designed to maintain backward compatibility with the v4.0 standard:
Advanced Beacons The wide-ranging enhancements implemented in Bluetooth 5 open innumerable possibilities for more advanced beacons. With larger advertising packets, more content can be provided in an advertising event. In addition, a single physical beacon can support multiple beacon standards, each with different packet timing and formatting. Existing apps based on Bluetooth 4.0 beacons can still be compatible with Bluetooth 5 beacons, allowing a smooth transition while upgrading to more enhanced capabilities.
Benefits of Bluetooth 5.0 Bluetooth 5.0 achieves 2x the speed, 4x the range, and 8x the broadcast capacity of previous versions. As a new and large market potential, the building blocks are now available to create advanced beacons using Bluetooth 5. To learn more about how Bluetooth 5 can enhance your second-generation beacons, read this whitepaper. |
