AT&T Debuts 5G Channel Sounder 'Porcupine' with NI

The "Porcupine" is out, and it's making its debut in all its shiny grandeur. Nicknamed “Porcupine” within AT&T, a new millimeter-wave channel sounder was introduced this week as a first-of-its-kind device.

Looking a bit like something that might be walking and talking in a Star Wars movie, the sounder was developed with the help of National Instruments (NI) to capture how wireless signals are affected in a given environment. It can be used to measure how signals reflect off of, or are blocked by, objects like trees, buildings, cars or people.
