Qualcomm’s ultraBAW filters cover 2.7 GHz to 7.2 GHz, keeping cellular and Wi-Fi in place. Qualcomm explains how the filters work. Each time a government auctions off a slice of spectrum for cellular use, the airwaves get more crowded as users begin occupying the new frequencies. In the days when spectrum wasn’t so scarce, cellular…
