Radio based sports tracking comparison

Explantion of the graphics The graphic is based on radar tracking physics.

At the top of the graphic:  
The frequency spectrum shows how wide the bandwidth (BW) is relative to WiFi.
WiFi typically has 20 MHz of bandwidth (max 80 MHz). UWB (ultra wideband) 500 MHz in green.
5G Phone networks operate at 3500 MHz. UWB channels 3 and 5 are most used.

For accurate distance measurements a 500+MHz bandwidth works best.
For sports tracking UWB (ultra wideband) is most accurate.

BW=Bandwidth in MHz (higher is better)

Improvements in accuracy are possible by:
- better electronics timing (TCXO)
- better signal quality, Low Noise Amplifier
- use more then 1 antenna
- using more measurements per second. Higher update rates
- using more anchors (reference points)
- software filtering


Tracking methods
3D sport pefromance tracking


Most technologies have lower accuracy at longer distances.
Sustainable accuracy at a distance is provided by:
- Laser ranging
- UWB
- Motion capture
- Infrared optical cameras are accurate with limited range of about 30meter.



OUTDOOR
Optical (camera) systems have issues with outdoor conditions like direct sunlight, snow, blocking of direct view by field players.


3D tracking
Multiple reference points for observations are required for any technology
Single point of view, stereo scopic cameras with AI also need multiple vantage point to solve oclusion and degrading accuracy over distance, low update rate and massive data processing and installation cost (cabling).
