Real scenarios from this area, for your reference

The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.

The client moved into a new office in Xinhe, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.

The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.

AP deployment is RMB 150–400/AP, whole-home plans from RMB 800, depending on area, floors and whether cabling is needed. Survey is free — we give a point map and budget first.
