## Abstract

In one aspect, a computerized method useful for implementing location awareness a vehicle coupled with an on-board diagnostics (OBD) pass-through dongle includes the step of providing a plurality of wireless personal area network (WPAN) beacons, wherein plurality of WPAN beacons transmits a low-energy WPAN signal. The computerized method includes the step of pre-mapping a plurality of subareas in the area with a set of signal attributes for each WPAN beacon of the plurality of WPAN beacons. The computerized method includes the step of coupling a vehicle with an OBD pass-through dongle, wherein the OBD pass-through dongle comprises a Low-Power Wide-Area Network (LPWAN) module, and wherein the OBD pass-through dongle comprises a WPAN module. The computerized method includes the step of, with the WPAN module, receiving one or more WPAN signals from the plurality of WPAN beacons.

## Claims

### Claim 1

A computerized method useful for implementing a location awareness vehicle coupled with an on-board diagnostics (OBD) pass-through dongle comprising
providing a plurality of wireless personal area network (WPAN) beacons, wherein the plurality of the WPAN beacons transmits a low-energy WPAN signal;
pre-mapping a plurality of subareas in an area with a set of signal attributes for each WPAN beacon of the plurality of the WPAN beacons;
coupling the vehicle with the OBD pass-through dongle,
wherein the OBD pass-through dongle comprises a Low-Power Wide-Area Network (LPWAN) module, and
wherein the OBD pass-through dongle comprises a WPAN module;
with the WPAN module, receiving one or more WPAN signals from the plurality of the WPAN beacons;
with the LPWAN module, communicating a LPWAN signal to a on-premises server network in the area,
wherein the LPWAN signal comprises the set of signal attributes for each WPAN beacon of the plurality of the WPAN beacons as received by the WPAN module; and
with the on-premises server network in the area, matching the set of signal attributes for each WPAN beacon of the plurality of the WPAN beacons as received by the WPAN module with the pre-mapped plurality of the subareas in the area with the set of signal attributes for each WPAN beacon of the plurality of the WPAN beacons to determine a sub area of the vehicle.

### Claim 2 (depends on 1)

The computerized method of claim 1, wherein the on-board diagnostics pass-through dongle is coupled with an OBD port of the vehicle.

### Claim 3 (depends on 1)

The computerized method of claim 1, the LPWAN network comprises a LoRa* network.

### Claim 4 (depends on 1)

The computerized method of claim 1, wherein the WPAN network comprises a BLUETOOTH® Low Energy (BLE) network.

### Claim 5 (depends on 1)

The computerized method of claim 1, wherein the set of the signal attributes for each WPAN beacon of the plurality of the WPAN beacons comprises a signal strength and a signal direction of each WPAN beacon in the subarea.

### Claim 6 (depends on 1)

The computerized method of claim 1, wherein the area comprises an automobile dealership premises.

### Claim 7 (depends on 6)

The computerized method of claim 6, wherein the subarea comprises a portion of a parking lot of the dealership premises.

### Claim 8 (depends on 1)

The computerized method of claim 1, wherein the on-premises server network maintains a table of the pre-mapped plurality of the subareas with the set of the signal attributes for each WPAN beacon of the plurality of the WPAN beacons.

### Claim 9 (depends on 1)

The computerized method of claim 1, wherein the OBD pass-through dongle communicates OBD-related data to on-premises server.

### Claim 10 (depends on 9)

The computerized method of claim 9, wherein the OBD-related data comprises an OBD accelerometer information, an OBD battery level information, and an ambient vehicle temperature information.

### Claim 11 (depends on 1)

The computerized method of claim 1, wherein the OBD pass-through dongle detects that a service provider's smart phone is within a specified pairing range of the OBD pass-through dongle and communicates an electronic message to the smart phone notifying the service provider that the service provider's smart phone is within the specified pairing range.
