In a field trial, Ericsson and Qualcomm Technologies completed the first over-the-air 5G New Radio (NR) call on CBRS (Citizen Broadband Radio Service) spectrum, according to a statement from Ericsson.
Ericsson said that the combination of 5G NR over CBRS will enable a wide range of new applications for enterprises and industry verticals, which in turn supports the proliferation of private networks, further propelling the Industry 4.0 evolution.
“The promise of 5G NR in the CBRS band offers nearly unlimited potential for enterprise applications and industries,” said Paul Challoner, vice president of network product solutions for Ericsson North America. “This demonstrates our technology leadership and investments to date, and the fruits of our collaboration to drive the promise of private networks in the Industry 4.0 evolution.”
Francesco Grilli, vice president of product management at Qualcomm Technologies said that the 5G NR call over CBRS spectrum was a milestone with Ericsson in enabling the potential of 5G and woud help address the increasing data demand and evolving uses for wireless connectivity among consumers, enterprises, governments and other organizations.
“Qualcomm Technologies has been at the forefront of commercialization of CBRS with support since 2017 in our Snapdragon Mobile Platforms, LTE modems and the Snapdragon X55 and X65 5G Modem-RF Systems,” Grilli said.
CBRS, which uses shared spectrum from 3.55 GHz to 3.7 GHz, has been the catalyst for innovation to expand cellular usage beyond enhanced mobile broadband (eMBB) in the United States, the statement reads. Combined with the commercial rollout of Priority Access Licenses (PAL), LTE-based CBRS network deployments are rapidly gaining momentum and proliferating across thousands of sites across the country, it said. The statement said that these sites enable use cases such as fixed wireless access (FWA), mobile network densification and private cellular networks.
“As the rollout of 5G NR network equipment in the CBRS band occurs, private cellular network performance will deliver improved throughput, reduced latency, enhanced reliability and greater connection density, thereby allowing for advanced applications such as mobile robotics, connected manufacturing and facilities and augmented reality industrial applications,” the statement reads. “In addition, the coordination of CBRS and licensed spectrum, such as C-band, through carrier aggregation further delivers increased capacity to enhance the user experience.”
According to Ericsson, with the first over-the-air 5G NR call, Ericsson and Qualcomm Technologies can deliver the power of 5G NR to CBRS shared spectrum. The field trial took place at Ericsson’s North America headquarters in Plano, Texas, using Ericsson’s 5G distributed innovation networkm together with a smartphone form-factor test device enabled by the Snapdragon 888 5G mobile platform and the Snapdragon X60 5G modem-RF system, Ericsson said. The standalone 5G network configuration with rooftop radios allowed for various real-life test scenarios, including intra- and inter-band mobility and carrier aggregation (3.55-3.7 GHz TDD and C-band), as well as mobility between n48 and 5G low-band, or 4G, Ericssson’s statement reads.
Ericsson radios 4408 and AIR 6449 and the smartphone form-factor test device were used for the trial, and the over-the-air environment was made possible with the use of FCC test licenses, Ericsson said.
