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.
US Cellular, Qualcomm Technologies, Ericsson and Inseego have achieved a 5G wireless communications extended-range milestone over millimeter-wave (mmWave) on a commercial network. The milestone was accomplished at a distance of 7 kilometers km (4.34 miles), the farthest 5G mmWave fixed wireless access (FWA) connection in the United States, with sustained average downlink speeds of ~1 Gbps, sustained average uplink speeds of ~55 Mbps and instantaneous peak downlink speeds recorded at greater than 2 Gbps.
Additionally, at a distance of 1.75 km (1 mile) with no line of sight, the companies achieved sustained average downlink speeds of ~730 Mbps and sustained average uplink speeds of ~38 Mbps. The test operators achieved the results in Janesville, Wisconsin, on US Cellular’s commercial network by applying Ericsson’s extended-range software to commercial Ericsson hardware Antenna Integrated Radio (AIR) 5322, along with an Inseego Wavemaker Pro 5G outdoor CPE FW2010e powered by the Qualcomm 5G fixed wireless access platform gen 1 featuring the Qualcomm Snapdragon X55 5G modem-RF system and a Qualcomm QTM527 mmWave antenna module.

Qualcomm Technologies has unveiled its next-generation modem purpose-built for Internet of Things (IoT) applications such as asset trackers, health monitors, security systems, smart city sensors and smart meters, as well as a range of wearable trackers.
The Qualcomm 9205 LTE modem brings together global multimode LTE category M1 (eMTC) and NB2 (NB-IoT) as well as 2G/E-GPRS connectivity, application processing, geolocation, hardware-based security and support for cloud services.
The modem is engineered to reduce power consumption by up to 70 percent in idle mode for battery-powered IoT devices that need to operate for 10 years or longer in the field. The Qualcomm 9205 LTE modem is also 50 percent smaller and more cost-effective than its predecessor – for IoT applications requiring low-power, wide-area connectivity in a small form factor device. The new modem is also software-compatible with the Company’s prior LTE IoT solutions, which allows module manufacturers to reuse software investments to develop new module solutions.
“The innovations included in the Qualcomm 9205 LTE modem are critical to support many of the 6 billion IoT devices expected to use low-power, wide-area connectivity by 2026,” said Vieri Vanghi, vice president, product management, Qualcomm Europe, Inc. “LTE IoT technologies are the foundation of how 5G will help connect the massive IoT, and we are making these technologies available to customers worldwide to help them build innovative solutions that can help transform industries and improve people’s lives.”
Global multimode LTE IoT modem and connectivity: Support for both 3GPP release 14 Category M1 and NB2 for operation with networks using any of these LTE IoT modes, as well as 2G/E-GPRS to allow for connectivity in areas where LTE IoT is not yet deployed. Category M1 mode also supports voice for applications such as monitored security panels, and mobility for applications such as asset trackers.
RF transceiver with fully integrated front-end: The Qualcomm 9205 LTE modem features an RF transceiver with extended bandwidth support from 450 MHz to 2100 MHz. It also integrates a comprehensive RF front-end, a commercial first in the cellular IoT space, which is designed to greatly simplify the design and certification of products using the new modem, and therefore accelerate time to commercialization.
Earlier this month, companies and vendors from across the wireless industry came together at Verizon’s facility in Irving, Texas to test 4G LTE technology over the CBRS (Citizen Band Radio Spectrum) spectrum. After the successful initial trials last year, Corning, Ericsson, Federated Wireless, Google, Nokia and Qualcomm Technologies are all collaborating in end-to-end system testing.
The CBRS band is made up of 150 MHz of 3.5 GHz shared spectrum, which until now has been primarily used by the federal government for radar systems. The FCC authorized shared use of the spectrum with wireless small cells in 2016. By using LTE Advanced technology, carrier aggregation and the spectrum access system (SAS), Verizon will be able to use this shared spectrum to add capacity to its network.
The end-to-end system tests are designed to accomplish several goals on the path to widespread commercial deployment:
Corning provided a SpiderCloud Enterprise RAN composed of a Services Node and SCRN-330 Radio Nodes. Ericsson’s Radio System solution is comprised of 4×4 MIMO, 4x20MHz Carrier Aggregation, including CBRS spectrum delivered over infrastructure aggregating Ericsson’s outdoor micro base station (Radio 2208 units) with the indoor B48 Radio Dot System in the same baseband (5216 units). Nokia provided FlexiZone Multiband Indoor BTS, FlexiZone Multiband Outdoor BTS and FlexiZone Controller.
In addition, participants in this ecosystem have set up private LTE sites which are using CBRS spectrum. Private LTE networks are being engineered to meet the needs of enterprise customers who want greater control over their LTE solutions including private on-site servers, control over access to their designated LTE network, as well as increased throughput and reduced latency through dedicated backhaul.
The end-to-end system testing, which began in February and will continue over the next several weeks, has provided actionable insights and have significantly advanced CBRS spectrum deployment feasibility.
“The promise of the CBRS band and enabling the use of wider swaths of spectrum will make a big impact on carrying wireless data in the future. These trials are critical to stress test the full system,” said Bill Stone, VP technology development and planning for Verizon. “There are many players in the CBRS ecosystem and these successful trials ensure all the various parts perform together as an end-to-end system for our customers’ benefit. We want to ensure devices efficiently use CBRS spectrum and that the new components effectively interact with the rest of the network.”
At the conclusion of this testing, equipment will be submitted for certification through the FCC. Following that deployment can then begin. Both commercial deployment of LTE on CBRS spectrum and devices that can access the CBRS spectrum are expected to begin in 2018.
CommScope, Ericsson Complete SAS Interoperability Testing for CBRS
To help ensure their readiness for commercial deployment in the CBRS wireless spectrum, CommScope and Ericsson have successfully completed interoperability testing of their equipment. The testing is one of the first successful interoperability tests using the Wireless Innovation Forum’s release 1.2 specifications.
“CommScope’s team of architects, developers and engineers have been building an industry-leading SAS for nearly two years,” said Tom Gravely, vice president of research and development, Network Solutions, CommScope. “Completion of interoperability testing with a major radio equipment provider such as Ericsson validates our SAS design and readies us for commercial deployment.”
The interoperability test confirmed that CommScope’s Spectrum Access System (SAS) and Ericsson’s radio infrastructure with CBRS spectrum support will work together as part of a CBRS network. The rigorous SAS–Citizens Broadband Radio Service Device (CBSD) interoperability testing used a battery of scenarios to verify that both products meet governmental requirements and industry protocols, as well as CommScope’s and Ericsson’s respective quality standards.
“Ericsson offers a comprehensive portfolio of CBRS network solutions that will help operators of all sizes deploy in this spectrum quickly and successfully,” said Paul Challoner, vice president of Network Product Solutions, Ericsson. “Additional milestones need to be reached for CBRS to become a reality, but we are pleased to complete interoperability testing with CommScope as part of the developmental process.”
In a CBRS network, a SAS and CBSD work together to ensure that the appropriate wireless signals are transmitted and received between the core network and end-user devices, while managing interference. An Environmental Sensing Capability (ESC) works with the SAS to identify the wireless signals of incumbent users to avoid interference from CBSDs. CommScope is one of four ESC operators conditionally approved by the FCC to provide SAS and ESC services.
Qualcomm Technologies, ZTE and China Mobile have achieved the world’s first end-to-end 5G NR Interoperability Data Testing (IoDT) system demonstrating a data connection based on 3GPP R15 standard. Following the guidelines of China Mobile, the IoDT connection demonstration took place at China Mobile’s 5G Joint Innovation Center, and utilized ZTE’s 5G NR pre-commercial base station and Qualcomm Technologies’ 5G NR sub-6 GHz UE prototype.
The end-to-end 5G NR system operates in the 3.5 GHz band and supports 100 MHz bandwidth, compliant with the 3GPP Release-15 5G New Radio layer 1 framework — including the scalable OFDM numerology, new advanced channel coding and modulation schemes, and the low-latency self-contained slot structure. The end-to-end 5G NR IoDT system is designed to efficiently achieve multi-gigabit per second peak data rates at significantly lower air interface latency than 4G networks.
“Implementation of 5G NR technologies will be critical to meeting the increasing connectivity requirements of emerging mobile broadband experiences such as streaming high-definition video and immersive virtual/augmented reality in the future, as well as enabling new high-reliability, low-latency services for autonomous vehicles, drones and industrial control, etc.,” said Cristiano Amon, executive vice president, Qualcomm Technologies, Inc., and president, QCT
The successful interoperable connection of the end-to-end 5G NR IoDT system serves as an industry milestone toward pre-commercialization of 5G NR technologies at scale, driving rapid development of 3GPP standards-compliant networks and devices.
