Track-iT & UWB: Frequency, Safety & Interference Considerations

Track-iT Operating Frequency

Follow-Me Track-iT uses Ultra-Wideband (UWB) channel 5, which operates in the 6240 – 6738.2 MHz frequency range, with a center frequency of 6489.6 MHz and a bandwidth of 499.2 MHz. This channel is designated for UWB tracking systems, ensuring reliable performance with minimal interference. Channel 5 is accepted in most parts of the world without any limitations, with the notable exception of Japan.

Interference Considerations

UWB Channel 5 operates within the 6 GHz spectrum. Other technologies such as Wi-Fi 6E (5925–7125 MHz) and certain wireless video/camera systems also use this band. For reliable operation, it is essential that no other devices transmit in the same frequency range as Track-iT. Strong emissions from Wi-Fi access points, wireless cameras, or other equipment in the 6 GHz band can disrupt or even completely stop Track-iT operation.

For optimal performance, ensure that the Track-iT system has exclusive use of UWB Channel 5 and avoid placing other 6 GHz transmitters in the same environment.

Safety and Power Concerns

Some of our users occasionally raise concern about the power, radiation, emissions, etc. from the Tracker whilst wearing it on the body or on/near the head.

Whilst this may seem concerning, we would like to show how our adopted technology (Ultra Wide Band or UWB) can operate perfectly safely, with little concern for problems. UWB is a standardized and regulated wireless technology, specifically designed for safe operation, including in close proximity to the body.

Transmission Power

The diagram below shows various wireless technologies and their transmission power.

We can see Power Spectral Density on the Y-axis; think of this more simply as the transmission power of the relevant components. In the case of Follow-Me, this is the transmitting power of an Anchor or Tracker. Governed by UWB standards, this means our transmission power is -41.3 dBm/MHz, which is incredibly low compared to the other technologies.

The diagram below shows the massive power difference between UWB and the others (including GPS and even your smartphone). The conversion to Watts helps you see that the Tracker using UWB is a mere fraction (nanoWatts) of the power coming from the other potential devices – there is simply no need for concern.

Our Commitment to Safety

At Follow-Me we take safety concerns and the impact of our technology seriously when it comes to our performer tracking systems.
