It tests, or implements by installation and using specifically App is tested the speed.
As it can be seen that prior art has the disadvantage in that
1. the Wi-Fi intensity on mobile phone, plate indicates icon, come according only to received signal strength and manufacturer's custom rule
It is given, do not reflect actual user's experience；
2. carrying out Wi-Fi upload, downloading rate measurement by installing App mode, it can not accomplish to continue to monitor and multiple spot is supervised
It surveys；
3. needing user itself to have certain professional knowledge, and realize event by tool when encountering network-in-dialing problem
Barrier diagnosis positioning；
4. not providing the intuitive network quality of user (state, failure) information and network failure alarm.
In view of the above-mentioned problems, there is no good solution in the prior art.
