On September 1, 2021, Ericsson and Qualcomm Technologies announced that both parties have recently realized important industry outcomes in the field test - successfully completed the first 5G NR OTA call based on CBRS (citizen broadband radio business) spectrum. The CBRS spectrum combines 5G NR, which will support enterprises and vertical industries to create a wide range of new applications, which in support the popularization of enterprise special networks, and further promote the evolution of industrial 4.0.

Paul Challoner, vice president of Ericsson North American Network Product Solution: "5G NR service based on CBRS band is expected to provide almost unlimited potentials for enterprise applications and many industries. We are very happy to reach high-pass technology companies to achieve this groundbreaking industry results. This reflects our technical leadership and long-term investment, as well as the cooperation results of both parties in the enterprise special network in the process of driving industrial 4.0. "

FRANCESCO GRILLI, Vice President of Product Management, Qualcomm Technology, said: "The 5G NR call based on CBRS spectrum is an important milestone in our joint Ericsson to help release 5G all potential, which will help meet consumers, companies, governments, and other organizations. Data requirements for wireless connectivity, and support the evolving use case. Qualcomm technology has been at the forefront of CBRS commercial, since 2017 passed the SnapdragonTM mobile platform, LTE modem and the Snapdragon X55 and X65 5G modems and RF systems To provide support. We are very happy to be able to create opportunities for CBRS in a wide range of scenarios, and empower better user experience. "

The CBRS band is a shared spectrum from 3.55 MHz to 3.7 MHz, which has become an innovative catalyst that extends the cellular network to more use of the enhanced mobile broadband (EMBB). Combined with priority access licenses (PAL) commercial deployment, LTE-based CBRS network deployment rapidly develops to thousands of sites in the United States. These sites support many use cases such as fixed wireless access (FWA), mobile network intensive deployment and cellular communication network.

With the deployment of 5G NR network devices based on CBRS band, cellular communication networks can support higher throughput, lower delay, higher reliability and connection density in powerful performance, thus support mobile robots, networked manufacturing and equipment , Enhance advanced use cases such as reality industrial applications. In addition, a synergistic communication of license spectrum such as CBRS spectrum and C band is implemented based on carrier aggregation, and network capacity will further increase network capacity to enhance the user experience.

Ericsson and Qualcomm Technologies have brought advanced 5G NR characteristics for CBRS sharing spectrum through the first 5G NR OTA call of this implementation. The external field test completed the Ericsson North American headquarters located in Pleinno, Texas, using the previously released Ericsson 5G distributed innovation network and the integrated Snapdragon X60 5G modem and radio frequency system Snapdragon 888 5G mobile platform Smartphone form test terminal. This trial uses 5G independent networking mode, combined with the roof deployment of wireless network equipment, supports diverse actual test scenarios, including band internal and inter-band mobility and carrier polymerization based on 3.55-3.7GHz TDD and C bands, and Mobility between N48 and 5G low band or 4G band.

This test uses Ericsson 4408 wireless devices and AIR 6449, as well as test terminals of smartphones, and builds an OTA test environment based on the US Federal Communications Commission (FCC) test license band.

Ericsson and Qualcomm Technology provide a complete set of solutions to help meet the needs of customers such as manufacturing, mining and ports to low-delay, reliable indoor cellular communications, and support massive network terminals. The above solution will assist the industry in a wide application scenario based on CBRS shared spectra to accelerate deploy advanced 5G NR characteristics. Ericsson has been focusing on strengthening the indoor 5G product portfolio, making it the easiest, flexible product line in the market, as well as high performance, reliable, cost-effective and easy deployment solutions.

With the end of the external field test, the two sides in promoting 5G services based on CBRS shared spectrum, release more innovative opportunities by helping 5G service based on the above transformation shared spectrum.
