Ossia has received Federal Communications Commission approval to use the 2.4 GHz frequency. The downside of that approach is that it lacks the range and directionality of higher frequencies. On the other hand, the lower frequencies don’t need the clear line of sight that infrared frequencies do and they’re not stopped by the obstructions that hamper millimeter waves. It’s all a trade-off. It really depends on what you’re trying to accomplish.
