Definition
Beacon is a broadcasting device based on short-range wireless technologies such as BLE, which periodically broadcasts its unique identifier (UUID, Major, Minor) and signal strength (RSSI) to the surrounding area. Nearby smart terminals or dedicated receivers can receive the Beacon signals to achieve applications such as indoor positioning, proximity information push (Proximity Marketing), asset tracking, and electronic fences. Beacons are usually battery-powered, with a lifespan of several months to even years.
Beacons are often used together with cellular IoT: Beacons handle near-field sensing and positioning, while gateways or aggregation devices transmit Beacon data back to the cloud platform via cellular networks. In scenarios such as cross-border retail and cross-border warehousing, Beacon deployment and cellular backhaul need to consider local frequency bands and compliance requirements.
Technical Features and Architecture
The Beacon architecture includes: Transmitter — Beacon devices broadcast BLE packets at set intervals (e.g., 100ms–1s), containing UUID, Major, Minor, TxPower, etc.; Receiver — Mobile apps, gateways, or dedicated receivers scan and parse the broadcasts, estimating distance (near/mid/far) via RSSI; Cloud — Receivers upload Beacon data, and the platform performs location calculation, geofence alerts , and statistical analysis. Supports protocols like iBeacon and Eddystone.
Beacon combined with geofence push can trigger information pushes within the electronic fence. When used with cellular gateways, the gateway must support multi-country SIM to ensure stable return in cross-border deployments.
Application in IoT and cross-border scenarios
Beacon is widely used in: Retail and Marketing — Indoor positioning and proximity promotions in shopping malls, airports, and cross-border stores; Warehousing and Logistics — Accurate positioning of shelves, pallets, and forklifts in warehouses; cross-border warehouses need integration with logistics tracking systems; Smart Buildings — Occupancy detection and navigation for meeting rooms and workstations; Museums and Exhibition Halls — Explanation pushes next to exhibits. In cross-border scenarios, Beacon deployment must comply with each country's radio regulations, and return gateways can use international IoT SIM cards for unified global management.
SimtoLink provides international IoT SIM cards and multi-country solutions for Beacon gateways and aggregation devices, ensuring reliable cross-border backhaul of Beacon data.
