Government-Wide IoT Network (GWIN)

Introduction to Government-Wide IoT Network (GWIN)

To assist digitalisation of E&M equipment, the Department is building a government network of wireless sensors installed throughout Hong Kong to support various smart applications for the improvement of public service quality.

Traditional sensors would each require a 4G connection to connect to central servers. In the GWIN network, sensors are connected to gateways via the low power and private LoRa (Long Range) network. The network with low power consumption reduces the cost and complexity of installing the sensors, and improves the security of the system and data without the need of using a third-party network.
