Hybrid ranging

A system comprising:

• a memory storage;
• and
• a processing unit, the processing unit coupled to the memory storage, wherein the processing unit is operative to:
• divide a coverage environment into a plurality of areas,
• determine a corresponding plurality of accuracy gradients of ranging for each of the plurality of areas,
• implement passive ranging for ones of the plurality of areas that have a high accuracy gradient of ranging and one of a high client device density and low client device movement,
• implement active ranging for ones of the plurality of areas that have a low client device density, and
• switch, based on at least one of a level of client device density and movement speed of client devices, between passive ranging and active ranging for ones of the plurality of areas that have at least one of high client device density and high client device movement.

A computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:

• dividing, by a computing device, a coverage environment into a plurality of areas;
• determining a corresponding plurality of accuracy gradients of ranging for each of the plurality of areas;
• implementing passive ranging for ones of the plurality of areas that have a high accuracy gradient of ranging and one of a high client device density and low client device movement;
• implementing active ranging for ones of the plurality of areas that have a low client device density;
• and
• switching, based on at least one of a level of client device density and movement speed of client devices, between passive ranging and active ranging for ones of the plurality of areas that have at least one of high client device density and high client device movement.
