What is the accuracy of the location?

The Tive Solution relies on 3 methods to provide hyper accurate location. Below is the approximate accuracy for each location method:

  1. Satellite/GPS: 20 m (70 feet)
  2. Wi-Fi Geolocation: 50 m to 100 m (<200 feet)
  3. Cellular Towers Triangulation: 500m (0.3 miles)

What is Satellite/GPS ?

GPS is a satellite navigation system that sends location information (latitude, longitude) to our device. This method is the most accurate but requires the device to acquire GPS signal from the sky which is sometime not possible when device is deep inside a trailer or container. This method is disabled by default since it has a significant impact on the battery life, especially if the device does not good access to the GPS signal (near window or door).

What is Wi-Fi Geolocation ?

Using Wi-Fi signals is a great way to accurately position connected devices throughout the world in a battery-efficient way. This technology can provide precise location given the proliferation of Wi-Fi access points (APs) and advances in the technology in recent years. The Tive trackers simply listen to nearby wireless Wi-Fi access point signals without connecting to Wi-Fi networks and reporting these signals to the Tive data cloud to perform the location mapping. Tive uses a Wi-Fi geolocation engine which contains over 5 billions Wi-Fi access points and provide reliable information to locate a Tive tracker. By continuously applying proprietary algorithms to qualify these access points, we ensures that APs currently in the database can be relied upon for location accuracy, and any new APs identified are thoroughly vetted, so the information they provide is equally beneficial. This location method is enabled by default and has several major advantages:

  • It can work in areas where satellite positioning systems are unreliable, such as in dense urban areas and indoors. 
  • It uses existing Wi-Fi infrastructure to work, without any additional hardware installation, making it an extremely affordable option as well as an accurate one.
The accuracy depends on the number of APs that are observed and the environment in which they are deployed. Assuming that the ground truth of APs is precise, as the number of APs increases in a given area, the more accurate the location results will be. 

What is Cellular Tower Triangulation ?

Cell tower triangulation is another technique widely used to identify the location of the phone/devices. Tive trackers contain a cellular modem that connects to cellular networks globally to transmit data back to the Tive data cloud. During this process, the Tive devices will listen to all nearby cellular tower signals from various cellular networks from LTE (4G/5G) and GSM (2G) and report this information to the Tive Data Cloud to resolve its location. Tive location engine uses algorithms and cellular signals to seamlessly track the position of Tive devices including ones that roam across multiple networks. The Tive devices also support the Enhanced Cell ID (E-CID) which is a positioning feature introduced in the latest LTE radio standard. This technology allows to includes the accuracy of cellular location by 2x over the traditional cellular tower positioning
