TWIG’s Indoor Location Tracking Devices Are Better Than GPS
Unlike GPS (global positioning systems) devices which are very useful outdoors yet not so useful indoors, TWIG Australia’s indoor location tracking devices are extremely apt at finding the precise location of individuals carrying the devices inside a superstructure. The TWIG Short-Range Device (SRD) can read signals from proprietary TWIG beacons, bluetooth and WiFi.
The reason why GPS signals don’t work so well indoors is because the roof of any superstructure tends to block signals to and from satellites. Also, the proximity of one GPS device to other GPS devices in a shopping centre, school or hospital is responsible for causing distortion of the signal which reduces the ability of the devices to perform location tracking functions.
Furthermore, GPS signals are not effective at locating people vertically. So, if a worker is facing an emergency in a skyscraper, for example, it is three times harder to locate that worker than if they were in a single storey building.
For indoor positioning, location based devices use primarily a combination of proprietary signals and a WiFi network to track the location of the person carrying the device. A TWIG device will scan for TWIG beacons and then transmit information about its proximity to the beacons to TWIG’s cloud software, TWIG Point via WiFi. The software then calculates the exact location of the device according to its proximity to the beacons.
On TWIG Point a virtual map can be uploaded to help locate persons in distress. The location of TWIG beacons can be programmed into the map and signals will consequently indicate where a worker in distress is located. This can make response times way faster because security and emergency services are able to use a visual representation of the building where the emergency is occurring to locate the person in distress.
It is, in fact, even possible to locate a person in distress without using TWIG Point cloud software. Without TWIG Point, in an emergency, the number associated with the closest beacon will be sms’ed to an emergency contact.
This feature is incredibly useful in large commercial or government superstructures where security, nurses, teachers or other workers may be working alone; some distance from any other workers. In the event that there is a security breach, a violent patient or a wild animal present, workers equipped with indoor location finding devices can contact security for help before the danger escalates.
