Channel polling is used in applications such as smart home locks, phone locators, pet trackers, and industrial and commercial Internet of Things (IoT) solutions like geofencing and access control. This professional kit provides a complete reference design for the EFR32xG24 wireless system-on-a-chip (SoC).
The professional kit includes two wireless baseboards per kit, two dipole antennas, and two radio boards. For reliable performance in all applications, the professional kit offers Ethernet and USB connectivity and a Silicon Labs relative humidity and temperature sensor. The devices, one the initiator and the other the reflector, exchange information via 72 physical RF channels: the initiator transmits and the reflector responds.
The two devices exchange data packets and calculate the distance between them based on the time it takes for the packets to travel. This cross-checking process of the product's channel probing helps detect anomalies to ensure application security, which is crucial in developing access control solutions for hospitals and industrial buildings.
