Adant has applied its unique smart antenna technology combined with advanced machine learning algorithm to enable deep-sub-meter location capabilities for BLE, WiFi and UWB based gateways and beacons. Adant offers its patented solution to achieve best location accuracy at lower costs than other equivalent location systems on the market. 


When a radio signal is sent from the transmitter to the receiver it bounces back (i.e. is reflected and diffracted) multiple times on the surrounding walls and obstacles, thus creating multiple replicas at the receiver of the original signal with different amplitude and phase.

This significantly complicates the task of determining the Angle-Of-Arrival (AoA) and Time-Of-Flight (TOF) of radio signals which is the key to accurate estimation of position.

Furthermore, standard real time location systems employees omnidirectional antennas with low gain or passive directional antennas causing each location gateway/beacon to have limited coverage. 

Adant smart antenna technology strongly reduces the impact of multi-path effect by creating multiple different radiation patterns with each single antenna element and using its sophisticated machine-learning algorithms to improve the AoA/ToF estimation. Moreover the capabilities of exciting multiple switchable high gain beams in every direction allows the coverage of each location gateway/beacon to be significantly enhanced.



By using its unique, advanced smart antenna technology, Adant deep-sub-meter location technology defeats multi-path and extends the range of signals and strongly improves 3D coverage. Intuitively, it’s like having multiple gateways/beacons in one single compact case, each focusing on a particular region of the space to be tracked.

Deep-sub-meter precision can thus be obtained with as few as one or two beacons where other systems would require four or more of them.

For system developers and system integrators this translates into lower system capex cost and lower cost of ownership (installation & maintenance) at same or better precision and coverage performance
