AT&T Labs has completed what it said was the industry’s first 5G RedCap data connection in an effort to expand 5G in IoT devices. RedCap chips, short for Reduced Capability, 5G, support devices such as low-end augmented reality wearables, small cells, video surveillance equipment, industrial sensors, and smart grids.
Working closely with Nokia and MediaTek, AT&T tested 5G RedCap on MediaTek’s RedCap platform connected to the 5G SA network built with Nokia AirScale. AT&T made the first data call on its live network on July 19.
“This industry-first accomplishment in the U.S. will pave the way for 5G RedCap devices expected in the coming years,” the carrier said in a press release.
Introduced with 3GPP Release 17, 5G RedCap is designed for devices currently served by LTE CAT-4 but provides equivalent or better in performance with up to 150 Mbps theoretical maximum downlink throughput. It helps reduce the complexity, cost and size of 5G devices. It also introduces options to allow devices to operate at lower power levels.
“Looking ahead, AT&T is working with the ecosystem for additional advanced 3GPP power saving features for 5G RedCap, including wake up signal, early paging indication, PDCCH monitoring adaption and more,” the carrier said.
