Detection mechanism for magnetic distortion

An access point (AP) comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, the memory storing instructions to cause the at least one processor to:
• obtain a location of the AP from a global navigation satellite system (GNSS) sensor in the event that the AP is outdoor;
• or
• obtain the location of the AP from a location service provider in the event that the AP is indoor;
• obtain a reference inclination value and a reference intensity value of a magnetic field intensity based on the location of the AP;
• obtain, using a magnetometer and an accelerometer of the AP, an inclination value and an intensity value of the magnetic field intensity associated with the AP;
• determine a first difference between the reference inclination value and the inclination value associated with the AP, and a second difference between the reference intensity value and the intensity value associated with the AP;
• determine that the first difference exceeds a first threshold or the second difference exceeds a second threshold;
• and
• detect, based on the first difference exceeding the first threshold or the second difference exceeding the second threshold, a distortion for at least one of the inclination value and the intensity value.

A non-transitory computer-readable medium comprising instructions stored thereon which, when executed by an access point (AP), cause the AP to:

• obtain a location of the AP from a global navigation satellite system (GNSS) sensor in the event that the AP is outdoor;
• or
• obtain the location of the AP from a location service provider in the event that the AP is indoor;
• obtain a reference inclination value and a reference intensity value of a magnetic field intensity based on the location of the AP;
• obtain, using a magnetometer and an accelerometer of the AP, an inclination value and an intensity value of the magnetic field intensity associated with the AP;
• determine a first difference between the reference inclination value and the inclination value associated with the AP, and a second difference between the reference intensity value and the intensity value associated with the AP;
• determine that the first difference exceeds a first threshold or the second difference exceeds a second threshold;
• and
• detect, based on the first difference exceeding the first threshold or the second difference exceeding the second threshold, a distortion for at least one of the inclination value and the intensity value.
