Unlike point-to-point systems like Bluetooth, Zigbee forms a self-healing mesh where devices can relay signals, making it resilient in complex environments.
An IoT module is designed to connect things to the cloud using NB-IoT, LTE Cat M1, and 2G serves as a bridge between physical hardware and cloud-based systems.
Passive RFID tags require no internal power source, relying on the energy emitted by readers. Highly cost-effective when millions of items need tagging.
