What are Beacons? Beacons use Bluetooth technology to connect a specific physical point like a shopper in a mall with the Internet of Things, a physical mesh of ordinary items all embedded with electronics, softwares, and sensors. Beacons utilize the IoT to communicate with smartphones, both up close and across a room. Each beacon sends out a short-range radio signal regularly. In fact, they can transmit these signals ten times or more in a second. Bluetooth-enabled devices, like smartphones, pick up these signals when in range. A beacon’s capabilities depend heavily on what their owner has programmed the infrastructure to do. Some might offer specific information like details for a venue or timetables for a train. Some can offer full real-time wayfinding. Once the smartphone using the relevant app picks up the beacon signal, the next step is automatically triggered.
