Ultrasound vs RFID

It's the unique natural attributes of ultrasound which makes USID technology ideal for Real Time Location Systems requiring reliable location data with high levels of accuracy.

Sonitor's RTLS platform uses ultrasound as its means of communications. Ultrasound has several desirable properties that make it ideal for this application:

1. It does not penetrate walls, so location per room is simple to achieve.
2. It does not require line of sight between the tag and the receiver.
3. Ultrasound waves are mechanical waves and immune to interference. They do not interfere with sensitive equipment that might otherwise be disturbed by electromagnetic waves.
4. The security of an ultrasound system is very high, making it virtually impossible to eavesdrop on the communications link from outside the premises of the installation.

The Sonitor ultrasound system has been designed for safety, so all emitted sound pressure levels are within the international regulations for the safe use of ultrasound.
