The Smart Gas solution offers three major benefits. First, the solution enables real-time data backhaul and ensures safety. Data related to gas, such as device pressure and temperature, is transmitted to the management platform for real-time analysis. This facilitates preventive maintenance and eliminates safety hazards. Second, automatic meter reading helps residents avoid disturbances caused by manual meter reading and difficulties in bill payments. This adds further convenience to people's lives and reduces overall user complaints. Third, new profit models are derived from the development of smart gas. For example, residents can ensure the timely payment of property management fees through a purpose-built in-house smart gas mobile app.
The development of smart gas services had for many years been restricted by traditional two-hop network communications technologies such as Long Range (LoRa) and RF networks. Network construction is particularly quite difficult to accomplish using traditional technologies. For example, concentrators can only be deployed after site selection, electricity connection, and network planning. Different locations and scenarios cannot use the same solution. Network construction often requires a long period of time. In addition, concentrators tend to suffer from an inability to withstand extreme weather conditions such as lightning, rain, or snow. As a direct result, concentrators may require frequent maintenance. For example, connection of mains electricity may be affected by man-made faults, and accidental solar power supply faults may occur due to heavy snow. Furthermore, LoRa and RF networks operate on unlicensed spectrum. Networks used by different applications, such as natural gas, water, street lamps, and parking, often experience co-channel interference. And it is difficult to coordinate all walks of life to help eliminate this problem.
Huawei NB-IoT Smart Gas Solution
NB-IoT offers deep coverage and massive connections with low power consumption. It is an ideal network communications technology for the smart gas solution.
Inherited networks: The NB-IoT Smart Gas Solution runs on operator networks upgraded from the existing 2G, 3G, and 4G networks. Gas meter vendors and natural gas utilities save considerable amounts of time and money required for network construction.
Maintenance free: The NB-IoT network can be smoothly upgraded to 5G and is maintained by industry specialists from operators.
Highly reliable: The NB-IoT network uses licensed spectrum and suffers from low interference. The solution can achieve a meter reading success rate of over 99%.
The NB-IoT Smart Gas Solution helps natural gas utilities achieve preventive maintenance, provide convenient services, and increase profits. The solution enables the large-scale rapid growth of smart gas services.
Huawei and China Telecom are currently working with Shenzhen Gas on the NB-IoT Smart Gas solution pilot project in Shenzhen and with Beijing Gas on a pilot project in Beijing.
