Verizon's patented system is designed to detect "spoofing attacks" (U.S. Patent No. 12587857) on cellular base stations by comparing a station's known "true position" with a "real time position" calculated from satellite signals, generating an alert when the distance between the two exceeds a set threshold. Grapevine inventor Jerry Gamble, Jr. and Flower Mound inventor Sumanth S. Mallya are named on the patent. [Image: istock Illustration: ThinkNeo/iStockphoto; DI Studio]
