The COVID-19 pandemic demonstrated the importance of continuously monitoring indoor air quality, especially in schools. The Ministère de l’Éducation du Québec has announced in September 2021 the deployment and installation of air quality and comfort parameters sensors in more than 47,000 classrooms across the province.They need:Reduce maintenance and installation difficultiesMonitor CO2, humidity and temperature level at 5 minutes intervals during school hoursCreate an information system without the use of Wi-Fi or Cellular Internet

In commercial buildings, temperature, humidity, and air quality are all important for people's health and productivity. High levels of CO2 inside commercial buildings can cause many health concerns, commonly known as SBS (Sick Building Syndrome). Increasingly sophisticated smart buildings are being developed by nations around the world to improve efficiency, reduce costs, and generally make the environment healthy for residents and business owners. Additionally, under the looming climate crisis, energy prices began soaring last year. The need for building energy usage optimization has never been this urgent.The AI-driven system requires accurate and real-time environmental data for analysts to provide alerts and recommendations to the building operators when sensors show that pre-determined thresholds have been exceeded, or to optimize the building's operation to save money. The existing sensor system functioned poorly with critical problems:Poor SignalThe original solution was based on a techonology with limited signal coverage, up to 60% of sensors onsite were down at any moment.Excess MaintenanceThe original solution was based on a techonology with limited signal coverage, up to 60% of sensors onsite were down at any moment.Extra ExpenseEach Temperature and CO2 sensor required a sim card that generated an extra $500 monthly for each floor.

To thrive in the industry 4.0 era, many factories are always looking for ways to improve efficiency and enhance reliability, and power plants are no exception. Any idle time resulting from an operational glitch directly impacts both the top and bottom lines of the business. Thus, the network is central to everything the plant generates. To improve the network infrastructure, the Milesight CPE units, which are 5G-ready and Wi-Fi integrated, are implemented in a power plant to provide a wireless solution for high-speed, reliable connections with low latency.The Beihai Power Plant Phase II is an expansion project, which is a major project promoted by GFIG to build a stable and reliable “energy network” for Guangxi province, China.A 24-by-7 operation spread across 136,500 square meters (0.05 square miles). They were actively seeking a solution with the latest wireless network technology so that they could successfully interlink all mobile devices and office equipment without any downtime, meanwhile, exchange the data securely on the private network.Frustrated with network downtime, unstable connectivity, and spotty coverage, this coal-fired Beihai power plant was desperate.Wireless DeploymentTime equals money. Wired deployment is not an option due to the tricky and time-consuming process, and if a buried cable is broken, it is expensive to repair, while industrial wireless deployment saves significant costs compared to an equivalent wired installation.Extensive ConnectionsMany smartphones and tablets in areas of the plant must be connected to wireless networks to enhance workers’ capabilities, saving time and money in the long run.Dedicated NetworkA dedicated or private network is preferred as it is self-contained that can be deployed almost anywhere and managed centrally, providing a higher level of security.Harsh Work EnvironmentMetal buildings, machinery, massive magnets, extremely hot temperatures, and high humidity made it difficult to gain dependable signals or stable connections.Having tried some of the most well-known Wi-Fi and cellular solutions on the market, the IT network staff at the power plant turned to Milesight 5G CPE units with minimal investment in the new infrastructure.
