IoT gateway: The access point of most IoT sensors,provides WAN connectivity to low power consumption IoT sensors.

One of the most important aspects of IoT is “how” everything will be connected. Many IoT devices have been deployed in
short-range areas such as smart homes and offices. However, the market is now requiring wider coverage
networks where LPWAN (Low Power Wide Area Network) is introduced, it describes a set of technologies for transferring
very small amounts of data but spreading across a wide area. The LPWAN devices enables a long battery life of several
years, reducing operational costs and maintenance.

LPWAN technologies can be divided into licensed and unlicensed bands: LoRa and SIGFOX work in unlicensed bands, while cellular IoT, such as NB-IoT and LTE-M are typically used in licensed spectrum. Furthermore, NB-IoT and LTE-M have been standardized and are part of the 3GPP Release 13.

The gateway connects remote LPWAN devices. It is the network coordinator in charge of things like device authentication, message buffering, communication scheduling, and bridging devices from LPWAN to enterprise network via traditional communication methods like Ethernet or Cellular network. Eventually, users could monitor and manage these devices and the associated assets with cloudbased management systems. For those licensed LPWAN, the telecom operators would take care and be in charge of setting up the gateways, aka, the base stations, as well.

WiiGate is an IoT gateway that may contain up to 4 radio interfaces: a WiFi 2.4 GHz (Access Point), a Bluetooth Smart
2.4 GHz , a Sub-1GHz (868/915 MHz), a GSM/GPRS/3G/4G/NB-IoT. WiiGate also integrates a GPS module for mobile applications and a backup battery that allows the device to continue operating for up to 24 hours in the event of a power failure. These features along with an aluminum IP65 enclosure allows WiiGate to be placed outdoors.
