It makes the computer on the network mobile, so it can quickly a...

AI Technical Summary

Problems solved by technology

While completing the wireless network supervision, there are the following defects: (1) Since the system needs to be re-established in the original wireless environment, the cost of supervision is increased; (2) The monitoring terminal is connected to the supervision server in a wired manner, and remote monitoring cannot be realized Network supervision; (3) It cannot only provide real-time supervision of the network, but cannot restore network events; (4) Due to the scattered distribution of supervision platforms, it is easy to form supervision dead ends, and users in some unsupervised areas can evade supervision
