I&#x27;ve been trying to solve an issue similar to what Beartooth is doing, and 2 miles is amazing range. Bear in mind, these aren&#x27;t huge towers hundreds of feet above the ground with 50kWh power sources and million dollar price tags, they&#x27;re battery-powered, handheld, and consumer-priced. And cell towers with all the advantages listed only travel less than 20 miles. 2 miles with those limitations is a great distance.<p>I think maybe you&#x27;re looking at the wrong use case. This doesn&#x27;t replace GSM, it replaces walkie-talkies (or rather updates it for the text-based world). The use case is you and your friends are at an event downtown and cell service goes out (like it does when the sites are oversubscribed). You&#x27;re camping and there&#x27;s no service that far in the woods. You&#x27;re in a disaster and trying to find your loved ones. It&#x27;s short range communications, not long-distance calling.<p>Ham radio would go farther, but sending encrypted communications over ham radio is illegal, so that&#x27;s right out. This is the next best thing.
