AT&T Offers AirGig Update, Reiterates Upcoming Trials for Fiber Fronthaul/Backhaul Alternative

AT&T AirGig millimeter wave broadband technology provides better propagation than traditional point-to-point wireless options because it uses wave guide technology, said Bill Hogg, president of technology operations at AT&T, today. Developed by AT&T, AirGig is designed to be deployed on the same pole infrastructure as electrical power lines but operates using millimeter waves. “It doesn’t actually use the conductor of the powerline itself,” Hogg said. “The wave is launched as a millimeter wave on the powerline as a wave guide.” AirGig is designed to support multi-gigabit speeds. AT&T has applied for or received 200 patents related to the technology, Hogg said. Hogg’s comments today provided a brief glimpse under the hood at how the technology announced last year works. AirGig Update A wave guide is a structure that restricts how much waves can expand over distance, thereby minimizing energy loss. According to Hogg, AT&T AirGig “takes existing powerlines and uses them as a wave guide for millimeter wave.” Propagation or the distance signals can travel, is much better than if “you just had millimeter wave antennas pointed at each other,” he noted. “It’s a great alternative to stringing up fiber, especially in rural areas where you have long runs,” he … Continue reading AT&T Offers AirGig Update, Reiterates Upcoming Trials for Fiber Fronthaul/Backhaul Alternative
