Beacon-based position awareness system

A method comprising:

• operating a client device comprising at least one hardware processor and a non-transitory computer-readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to:
• cause the client device to receive at least some of a plurality of directional signals transmitted by at least one transmitting device configured to transmit, in at least one plane, said plurality of directional signals, each covering an angular sector, wherein each adjacent pair of said angular sectors overlaps partially to create a logical sector, and wherein each of said plurality of directional signals encodes at least an indication regarding each of said logical sectors associated therewith,
• calculate a signal strength level (RSL) value for each of said received directional signals, and
• determine that said client device is located:
• (a) within one of said logical sectors, when the two highest said RSL values (i) are related to two of said directional signals associated with said logical sector, and (ii) are within a specified value range of each other, and
• (b) at a midpoint between said one of said logical sectors and a first said angular sector of a said adjacent pair creating said logical sector, when one of said two highest said RSL values corresponding to a second said angular sector of said adjacent pair corresponds to a location of said client device outside said second angular sector.

A computer program product comprising a non-transitory computer-readable storage medium having program code embodied therewith, wherein the program code, when executed by a client device comprising at least one hardware processor, causes the client device to:

• receive at least some of a plurality of directional signals transmitted by at least one transmitting device configured to transmit, in at least one plane, said plurality of directional signals, each covering an angular sector, wherein each adjacent pair of said angular sectors overlaps partially to create a logical sector, and wherein each of said plurality of directional signals encodes at least an indication regarding each of said logical sectors associated therewith;
• calculate a signal strength level (RSL) value for each of said received directional signals;
• and
• determine that said client device is located;
• (a) within one of said logical sectors, when two highest said RSL values (i) are related to two of said directional signals associated with said logical sector, and (ii) are within a specified value range of each other, and
• (b) at a midpoint between said one of said logical sectors and a first said angular sector of a said adjacent pair creating said logical sector, when one of said two highest said RSL values corresponding to a second said angular sector of said adjacent pair corresponds to a location of said client device outside said second angular sector.
