If AT&T is to launch mobile 5G service in 2018, it has to be sure its millimeter-wave frequencies and small cells work as planned. And tests suggest signal propagation will not be a problem.
In its Waco, Texas tests providing service to small and mid-sized businesses, mobile speeds of 1.2 Gbps, with latency between nine and 12 milliseconds were obtained at (roughly 450 feet) 150 meters distance, supporting “hundreds of simultaneous connected users” using the 5G network.
In Kalamazoo, Michigan AT&T found its small cell sites and millimeter wave frequencies were not degraded by rain, snow or other weather events. The signals even were able to penetrate significant foliage, glass and even walls better than initially anticipated.
Speeds greater than 1 Gbps in line of sight conditions were obtained at 900 feet (about 300 meters).
In South Bend, Indiana customers (consumer and small business) worked in both line of sight and some non line of sight locations.
