SAN DIEGO and DALLAS — The defense contractor Northrop Grumman and AT&T are working on 5G-enabled defense capabilities for the U.S. Northrop Grumman and AT&T Communications, part of AT&T, entered into a collaboration agreement to research and develop a "digital battle network" to support the U.S. Department of Defense (DoD), according to AT&T last month. The digital battle network will be powered by AT&T 5G and Northrop Grumman's advanced mission systems. The partnership is intended to deliver a scalable, open architecture network that will help the DoD connect distributed sensors, shooters, and data from all domains, terrains and forces. The partners believe the connections will be similar to how smart devices connect and share everyday data.
