Wi-Fi localization is a revolutionary technology that uses common Wi-Fi signals to locate objects and people inside buildings. It might seem complicated, but it's actually as simple as using Wi-Fi on your phone or computer.
How does Wi-Fi Location work?
Wi-Fi localization works with what is already in your building - Wi-Fi routers and access points. These devices emit signals that are picked up by sensors or Wi-Fi enabled devices such as smartphones or special tracking tags. This data is then analyzed and converted into location information.
Wi-Fi localization methods
- RSSI Multilateration : This method uses the received signal strength from multiple access points to determine location.
- Fingerprinting : This method compares the received signal with a database of known "fingerprints" of Wi-Fi signals in different locations.
- Time-of-Flight (ToF): ToF measures the time a signal spends traveling from a device to an access point and vice versa.
- Angle of Arrival (AoA) : determines the angle at which the signal arrives at the access point.
Why Wi-Fi localization?
Wi-Fi localization is great because:
- Uses existing infrastructure: Most buildings already have a Wi-Fi network, so no additional investment is needed.
- Increased availability: These days, almost every device has a Wi-Fi receiver, which means you can easily track your children's location.
- Flexibility: It can be used for a wide range of applications, from baby tracking to building navigation.
Examples of using Wi-Fi Location
- Item Tracking: Quickly locate important items such as medical equipment in a hospital.
- Building Navigation: Help visitors navigate large complexes such as shopping malls or airports.
- Security Applications: Detect unauthorized devices in sensitive areas.
How accurate is Wi-Fi Location?
Wi-Fi location accuracy can vary, but is usually accurate to within 10 meters. Improved methods such as ToF or AoA can provide even more accurate results.
The Future of Wi-Fi Localization
With the development of Wi-Fi 6 and other advanced technologies, Wi-Fi localization is expected to become even more accurate and reliable. It will be able to support a wider range of applications and become an even more important part of our daily lives.
Summary
Wi-Fi tracking is an amazing technology that uses something we already have all around us - Wi-Fi - to help us find people or things. It is an easy, accurate and flexible solution to many modern problems. Whether it's tracking expensive equipment in a hospital or making sure your kids are safe, Wi-Fi tracking is here to help.
