Abstract: The present invention discloses smart IoT end devices (500,502,503, etc.) system (100) supervised by a smart gateway device (400) at a secure site and secure methods of operating the system. An AI module (204), connected to a server (200) in the system (100), polls a quality of service of a low-power wide-area network (LPWAN) (300), the smart gateway, the smart IoT devices communication links (200,LR,SR), cellular (10,20) and any available network (including an IoT (302) at the secure site) and selects an optimal security level of operation according to any one of access scenarios A-E; access scenario A is endowed with the highest security level, whilst access scenario E is for off-line emergency operation. In all scenarios of operations, the gateway (400) and the smart IoT devices (500) are monitored at the server (200) ensuring 24-hours 7-days a week supervision.

Abstract: The present invention describes a gateway device (100, 100a) for wirelessly connecting IoT sensors, actuators or devices (150, 151, 152, etc.) and aggregating the sensor/actuator/device data into data packages (160); these sensor connections use short range (SR) wireless communication, which includes Bluetooth, BLE, Zigbee, NFC or similar wireless technology. The data packages (160) are then transmitted to a monitor centre (190) at predetermined time intervals via a low power, long range (LR), wireless wide area network (LPWAN), which includes NB-IoT, Sigfox, LoRa or similar wireless technology. BLE standard is modified to further reduce battery power consumption for use in the gateway device. In addition, scheduling of SR and LR transmissions averts wireless interference.
