Most laser tag systems use coded infrared signals for communication.

The Wizard Tag Wands also use infrared signals to tell the other wands what spells have been cast, any modifiers on the spell, who was the attacking Wizard, and so on.  

We need to know that the signals are received and understood completely by the receiving wand.  We also want to make sure that the ranges are correct.  The Ice-spike should have a long, narrow beam, and the Fireball should have a short range, with a much larger blast area.  

There are other things to look out for during testing, such as the ability to successfully communicate with infrared in sunny conditions.  Sunlight has a lot of energy in the infrared spectrum, which should be discounted by the hi-tech sensors in the wand.

Finally, most laser tag systems only have one sensor on the guns, and maybe multiple sensors on wearable items, like a connected laser tag vest.  Wizard Tag has everything you need to play built into the wand.  In order to ensure reliability of reception, we use multiple sensors.  The testing should show that integrating multiple sensors works and also whether or not there are more sensors than necessary.
