What is the difference between the RealTrac local positioning system and other systems on the market?

The RealTrac local positioning system is designed for professional use (initially developed for local positioning) and ensures exceptional positioning accuracy regardless of the distance to the user, the number of access points, and provides data transmission and voice communication via digital interference-free channel.
