VoiceLink | Issue 69 | GWIN Reaches Milestone with Number of Gateways Exceeding 500
In December 2020, the Government launched the Hong Kong Smart City Blueprint 2.0, with the Government-Wide Internet of Things Network (GWIN) included as one of the smart city infrastructures, so as to drive smart city development. In fact, the EMSD initiated a pilot project in Sha Tin District to install gateways for the GWIN back in early 2019. By mid-2020, we actively promoted the use of GWIN for real-time monitoring of E&M equipment to our clients. As at the end of 2023, the number of GWIN gateways exceeded 500, with network coverage spanning across Hong Kong Island, Kowloon, the New Territories and the outlying islands.
