How does Troverlo work from a technical perspective?

Technical overview of the Troverlo technology

Troverlo Asset tags mimic a Wi-Fi access point. Most Wi-Fi chips can be configured to operate as a Wi-Fi AP or a Wi-Fi client. To create an asset tag compatible with the Troverlo Platform the tag must mimic certain functions of a Wi-fi AP.

Specifically, the tag needs to mimic the Beacon functionality discussed in the Beacon section found here: 802.11 Frame Types and Formats

The Beacon must be broadcast in a manner consistent with the Wi-Fi standard.

A compatible asset tag does not need to have WAN connectivity, nor does it need to participate in the full complement of the Wi-Fi standard. It does not need to establish a data connection, associate, authenticate, or perform any functions other than what is required to send a Beacon and be discovered by Wi-Fi clients.

Troverlo Asset Tags broadcast the following information:

  1. BSSID (MAC)
  2. SSID (Network name)

Observation Endpoint (client devices):

  1. Capture the above Asset Tag broadcast data.
  2. Append data regarding Lat/Long, Speed, Altitude, HPE (horizontal accuracy of position)). RSSI (signal strength), Frequency of RF radio (2.4 GHz) + Channel.
  3. This combined data set is saved in the cloud and gathered by Troverlo
