The Smart Water Solution offers three major benefits. First, the solution adopts a grid-based water meter system, monitors the pipeline network in real time, and rapidly locates pipeline failures to enable leakage analysis. Thanks to this solution, the rate of water leakage can be reduced. Second, users often complain about disturbances caused by manual meter reading or inaccurate manual estimation. Automatic meter reading effectively solves all these issues, helping to reduce user complaints and improve service quality. Third, this solution enables real-time data backhaul. Data related to water, such as quality, pressure, and temperature, can be managed elaborately and visually to enhance the capabilities of water utilities.
The development of smart water 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, and 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 water, natural gas, 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 Water Solution
NB-IoT offers deep coverage and massive connections with low power consumption. It is an ideal network communications technology for the smart water solution.
Inherited networks: The NB-IoT Smart Water Solution runs on public networks upgraded from the existing 2G, 3G, and 4G networks provided by operators. Water meter vendors and water 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 Water Solution helps water utilities minimize water leakage, reduce user complaints, and improve management. The solution will accelerate the large-scale development of smart water services.
Smart Water in Shenzhen: Shenzhen Water, China Telecom, Ningbo Water Meter, and Huawei jointly launched the world's first commercial NB-IoT-based Smart Meter Reading project. 50,000 water meters have been deployed as of October 2017, and 500,000 water meters are expected to be deployed by 2020.
Smart Water in Yingtan: By October 2017, Huawei, together with Sanchuan Water Meter, had already released 20,000 NB-IoT smart water meters and achieved an online rate of 99.2%. They are expected to deploy 100,000 water meters in 2018.
Smart Water in Fuzhou: Huawei and Prajna IoT Tech Co., Ltd. will deploy 100,000 water meters in Fuzhou by 2017 and 300,000 ones by 2018.
Huawei eLTE Smart Water Solution
Huawei provides the eLTE Smart Water solution for customers who construct their own networks. The solution is based on unlicensed sub-GHz spectrum, exempting enterprises from certain licensing requirements.
The eLTE Smart Water solution uses built-in eLTE-IoT communication modules to detect the status of and collect hydrological data related to the water supply and drainage system in urban areas in real time. The detection is enabled through online monitoring devices, such as electronic staff gauges and water quality analyzers installed in rivers and low-lying areas. Water utilities and water supply and drainage facilities are visually integrated to monitor river water and water accumulation in real time. This solution analyzes and handles the collected data in a timely manner and enables water level monitoring, flood warning, and other functions. It uses eLTE-U video backhaul to monitor rivers, channels, major water gates, and enterprise sewage outlets, helping water utilities make decisions and suggestions based on the corresponding results.
The eLTE Smart Water solution offers wide coverage and massive connectivity, delivering highly reliable services with low power consumption. This solution can enable a maximum of 50,000 connections in each cell, prolong the battery life to 10 years, offer wide coverage of 3 km in urban areas and 7 km in suburbs, and provide encryption algorithms with high interference resistance to ensure data security.
Smart Gaoqing County: The development of technologies such as IoT, cloud computing, big data, and mobile communications, have all contributed to the construction of smart cities. By focusing on good governance, on people's welfare, and on economic revitalization, the government of Gaoqing County, in Shandong province, aims to turn Gaoqing into a model smart city. The government hopes to improve resource utilization, enhance urban management, and generally enhance the standard of living for the residents of Gaoqing. The smart city will continuously improve the ecological environment and successfully upgrade industries. Huawei built a 4.5G-based, LTE wireless broadband e-Government private network, and a metropolitan IoT private network integrating IoT, voice, video, and positioning services. The system enables multiple smart city applications to provide more comprehensive urban management. IoT has applications in public security, transportation, urban management, water services, environmental protection, security monitoring, healthcare, agriculture, and various other municipal services.
