Connect any number of IoT devices easily to the cloud, manage them in an visualized fashion, integrate and analyze data, as well as invoke open capabilities for service innovations. Fragmentation of devices is a serious problem. Long periods of interconnection can be caused by the complexity of standards and protocols. Devices cannot be managed efficiently, access to devices cannot be unified because of different access networks, and connections can't be stable. Event processing is difficult because devices are isolated from one another. Remote O&M is a cost-effective way for O&M personnel and contractors to remotely access device fault logs, locate faults and restart devices. This reduces labor costs.
