Intelligent street lamp is one of the most important application cases of smart city, but the traditional intelligent street lamp solution still faces a series of challenges, such as unstable network and multi-hop network operation mode. However, Huawei's intelligent street lamp solution based on NB-IoT technology includes street lamp monitoring terminal equipment, NB-IoT network connection, Internet of Things management platform, and cloud operation management platform. Its network structure is clear, application protocol is simple, and gateway is not required to enhance the stability and reliability of the system. At the same time, Huawei's smart street lamp solution can also reduce operating costs by half by monitoring each street lamp, leading to simpler and more flexible energy-saving configurations. In addition, the OceanConnect IoT platform provides real-time command issuance, offline command issuance management, periodic security data reporting, and remote batch device upgrades in conjunction with the NB-IoT wireless network. The OceanConnect IoT platform uses half the power of a traditional solution and extends the life cycle of the device.
