Abstract
A wireless communication device may determine that a channel is to be used to transmit an advertisement. The wireless communication device may determine a channel-specific gain associated with transmitting the advertisement via the channel. The wireless communication device may generate the advertisement to include information identifying a channel identifier of the channel and the channel-specific gain. The wireless communication device may transmit the advertisement for locationing based on a received signal strength indicator (RSSI) of the advertisement.
Claims20
A method, comprising:
- determining, by a device, that a channel is to be used to transmit an advertisement;
- determining, by the device, a channel-specific gain associated with with the transmitting advertisement via the channel;
- generating, by the device, the advertisement to include information identifying a channel identifier of the channel and the channel-specific gain;
- transmitting, by the device, the advertisement channel for locationing based on a received signal strength indicator (RSSI) of the advertisement channel;
- and
- storing, in association with a transmitter calibration of the device and in a calibration mapping, the channel-specific gain in association with the channel identifier.
3 more elements
A wireless communication device, comprising:
- one or more memories;
- and
- one or more processors communicatively coupled to the one or more memories,
- configured to:
- receive, via a channel, an advertisement from a beacon;
- identify, from the advertisement, a channel identifier of the channel and a beacon identifier of the beacon;
- determine, based on the beacon identifier and a location mapping, a location of the beacon;
- determine, based on the channel identifier, a channel-specific gain associated with receiving the advertisement via the channel;
- generate locationing information that includes the channel identifier, the channel-specific gain, and a measured received signal strength indicator (RSSI) of the advertisement channel;
- determine a distance between a location of the wireless communication device and the location of the beacon,
- wherein the distance is determined based on offsetting the channel-specific gain from the RSSI;
- indicate, based on the distance, the location of the wireless communication device to a display of the wireless communication device or a locationing platform communicatively coupled to the wireless communication device;
- and
- perform an action associated with the locationing information.
11 more elements
A tangible machine-readable medium storing instructions, the instructions comprising:
- one or more instructions that, when executed by one or more processors, cause the one or more processors to:
- receive locationing information associated with a wireless communication device;
- process the locationing information to identify advertisement information associated with an advertisement channel received by the wireless communication device from a beacon;
- determine, based on a channel identifier in the advertisement information, a channel used during communication of the advertisement;
- determine, based on the channel identifier, a channel-specific gain associated with the communication of the advertisement channel;
- determine, from the locationing information, a location of the beacon and a received signal strength indicator (RSSI) of the advertisement channel;
- determine, based on the location of the beacon, the RSSI, and the channel-specific gain, a location of the wireless communication device;
- and
- perform an action associated with the location of the wireless communication device.
6 more elements
A method, comprising:
- determining, by a device, that a channel is to be used to transmit an advertisement;
- determining, by the device, a channel-specific gain associated with transmitting the advertisement via the channel, wherein the channel-specific gain is determined from a calibration mapping that indicates the channel-specific gain for the channel;
- and
- generating, by the device, the advertisement to include information identifying a channel identifier of the channel and the channel-specific gain;
- transmitting, by the device, the advertisement for locationing based on a received signal strength indicator (RSSI) of the advertisement channel, wherein the calibration mapping includes respective gain information for each channel of a plurality of channels that are to be used to transmit the advertisement channel.
2 more elements
A method, comprising:
- determining, by a device, that a channel is to be used to transmit an advertisement;
- determining, by the device, a channel-specific gain associated with transmitting the advertisement via the channel;
- and
- generating, by the device, the advertisement to include information identifying a channel identifier of the channel and the channel-specific gain, wherein generating the advertisement to include the information comprises:
- including the channel identifier in a header of the advertisement channel;
- and
- including a value of the channel-specific gain in a payload of the advertisement channel;
- and
- transmitting, by the device, the advertisement for locationing based on a received signal strength indicator (RSSI) of the advertisement channel.
