1. A method for detecting an interference source in a wireless network in an industrial facility, the wireless network comprising a plurality of network devices, the method being implemented by a network management device and comprising:
a) receiving network quality information from the plurality of network devices, the network quality information from a corresponding network device including at least one network key performance indicator (KPI) indicative of signal quality at the corresponding network device, and a network identifier of the corresponding network device;
b) detecting a degradation in a section of the wireless network based on the network quality information from at least one device from the plurality of the network devices, the section of the wireless network comprises the at least one network device;
c) determining a geographical area associated with the section of the wireless network based on the network quality information from the at least one network device in the section of the wireless network;
d) determining a route plan and transmitting the route plane to an automated guidance vehicle based on the determined geographical area and network topology of the section of the wireless network for covering the geographical area, said determining the route plan comprising determining a plurality of locations in the geographical area for covering the geographical area;
e) determining a location of the interference source based on measurements of the at least on network KPI measured at the plurality of locations in the geographical area, from the automated guidance vehicle; and
f) controlling the automated guidance vehicle to proceed to each location from the plurality of locations in the route plan and measuring the at least one network KPI at the each location of the plurality of locations;
wherein the route plan for the automated guidance vehicle comprises the plurality of locations in the geographical area.
