Verizon deploys LTE over CBRS spectrum

Verizon announced 4G LTE over CBRS spectrum (Citizens Broadband Radio Service) using its live commercial network in Florida.

The deployment uses a combination of Verizon licensed AWS and 700 MHz spectrum aggregated with 50 MHz of CBRS band 48 spectrum.  Verizon said it has achieved peak speeds of 790 Mbps using LTE Advanced features including multiple antennas, 256 QAM, and carrier aggregation across the shared and licensed spectrum.  The deployments in Florida involved outdoor and in-building systems.

Ericsson provided Ericsson Radio DOT system for indoor and Radio 2208 for outdoor, Qualcomm provided its Snapdragon TM 845 mobile test device with X20 LTE for access to CBRS on mobile devices, and Federated Wireless provided the prioritization through their Spectrum Controller, a Spectrum Access System (SAS) that dynamically allocates channels within the FCC’s spectrum sharing framework for this band.  Ericsson also provided the domain proxy to enable the radios to communicate with the Federated Wireless Spectrum Controller.

Commercial devices that can access the CBRS spectrum are expected in 2018.

Verizon said this real-world deployment marks the beginning of public access to the 150 MHz bandwidth of 3.5 GHz shared spectrum which until now has been used by the federal government for radar systems.

“As more people use more wireless devices to do more things in more places, building a network to stay ahead of customer demand is crucial,” said Mike Haberman, VP Network Engineering for Verizon.  “This shared spectrum resource is a critical component of our strategy to add capacity to our network.”

“We have been aggressively working over the past several years on deploying LTE Advanced features.  We’ve fully deployed carrier aggregation in our licensed spectrum across our network in over 2,000 markets, and have 4X4 MIMO and 256 QAM deployed in over 810 markets nationwide for our customers,” said Haberman.  “Combining those features with this shared spectrum band will provide more capacity, higher peak speeds and faster throughput when accessing the network for our customers who have come to expect the latest technology and highest reliability from Verizon.”

Verizon and partners drive advancements on CBRS spectrum

Verizon is collaborating with Corning, Ericsson, Federated Wireless, Google, Nokia and Qualcomm on end-to-end system testing of solutions for CBRS (Citizen Band Radio Spectrum) spectrum.

Testing is being done at Verizon’s facility in Irving, Texas. The end-to-end system tests are designed to accomplish several goals on the path to widespread commercial deployment:

To test and verify the Spectrum Access System algorithms from Google and Federated Wireless are consistently providing the best channel match from the SAS database.
To test data rates, modulations and the customer experience using CBRS spectrum.
To test interoperability between infrastructure providers to ensure seamless handoffs between CBRS spectrum and licensed spectrum for customers.
To test mobility handoffs on the CBRS spectrum.
To evaluate performance and data from LTE over CBRS spectrum.

Federated Wireless and Google are providing prioritization through the Spectrum Access System (SAS) that dynamically prioritizes traffic within the FCC’s spectrum sharing framework for this band.

Qualcomm is providing its Snapdragon LTE modem, which is needed to access LTE on CBRS on mobile devices.

Corning, Ericsson and Nokia have provided indoor and outdoor radio solutions which can run on the CBRS Spectrum.

Corning provided a SpiderCloud Enterprise RAN composed of a Services Node and SCRN-330 Radio Nodes.

Ericsson’s Radio System solution is comprised of 4x4 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 (MBI) BTS, FlexiZone Multiband Outdoor (MBO) BTS and FlexiZone Controller (FZC).

Dell'Oro: Fast growth predicted for CBRS

The nascent Citizen Broadband Radio Service (CBRS) market opportunities are expected to grow 10-fold between 2018 and 2022 with total RAN investments approaching $1 billion, according to a new report from Dell'Oro Group.

“One of the more compelling propositions relating to the CBRS band is that it lowers the barrier to entry and provides opportunities for a wide range of participants to operate a public or private LTE network — or eventually even a 5G network — at a fraction of the cost of operating a typical network, utilizing licensed spectrum,” said Stefan Pongratz, Senior Director at Dell’Oro Group. “Taking into consideration both the enormous market opportunity with CBRS and the long list of caveats that could curtail the impact in the near-term, we expect activity to accelerate rapidly between 2018 and 2022 to support a wide range of participants to operate a public or private LTE network,” explained Pongratz.

Baseline specs complete for 3.5 GHz Citizens Broadband Radio Service

Ten baseline specifications for commercial operations within the 3.5 GHz Citizens Broadband Radio Service (CBRS) band are now ready to go.

  • CBRS Operational and Functional Requirements
  • CBRS Communications Security Technical Specification
  • CBRS Operational Security Technical Specification
  • SAS to CBSD Protocol Specification
  • SAS to SAS Protocol Specification
  • SAS Test and Certification Specification
  • PAL Database Specification 
  • CBRS PKI Certificate Policy
  • CBSD Test and Certification Specification
  • CPI Accreditation Standard

In April 2015, the U.S. Federal Communications Commission (FCC) adopted rules for CBRS, which opens 150 MHz of spectrum (3550-3700 MHz) for commercial use — while providing necessary protection of incumbent users of the band. Spectrum access is actively coordinated based on priority and granular location, making previously allocated spectrum available to new entrants and services.

The Wireless Innovation Forum (WInnForum) said this watershed event allows the finalization of CBRS products already in various levels of testing and sets the stage for the rollout of commercial CBRS networks.

Google: "Completion of these standards demonstrates that it is now possible to make major changes in how we approach managing spectrum resources to provide the abundant bandwidth essential to our society,” said Eric Schmidt, Executive Chairman of Google parent company Alphabet Inc. “This accomplishment shows that flexible, cloud-based management can enable spectrum to be used for many purposes simultaneously, and relegate the exclusive, command and control vision of spectrum allocation to history."

Nokia: “The CBRS shared spectrum band has been made available in the US, offering 150MHz of spectrum in a continuous block. This spectrum will enable cost effective coverage and capacity expansion at large scale. Completion of detailed specifications of the CBRS Baseline Standards, while working with various contributors from multiple companies, is a monumental milestone achievement,” said Ricky Corker, Executive Vice President, Nokia. “I would like to congratulate all members of the WInnForum in achieving this milestone. CBRS, using a unique 3-tiered shared spectrum approach, promises efficient use of spectrum, and I cannot wait to see the successful rollout in the US.”

Ericsson: “The completion of the CBRS Baseline Standards represents an important milestone for spectrum sharing, unleashing the band’s potential for innovation. Ericsson’s commitment to supplying LTE equipment for the band will ensure strong commercial support for the ecosystem,” said Paul Challoner, VP Network Product Solutions, Ericsson. “The wholehearted cooperation of incumbents, including the DoD, the NTIA, the fixed satellite industry, and the commitment of the FCC to the success of the CBRS is to be acknowledged. Ericsson looks forward to speedy certification of the SAS and ESC and a smooth transition to commercial operation of LTE nationwide in the 3.5 GHz shared spectrum band.”

Verizon: “Verizon is pleased to see the WInnForum make timely progress in publishing CBRS protocol and test specifications. These are critical steps in the testing of CBRS SAS systems, ESC systems, and CBSD devices and the eventual deployment of network infrastructure and consumer devices on this highly desirable CBRS spectrum,” says Ed Chan, Chief Technology Architect and Network Planning (NYSE: VZ). He added, “Access to additional wireless spectrum is essential for providers who want to deliver on the promise of next generation technologies. We believe the FCC’s new CBRS shared spectrum approach is an innovative and responsible way to leverage all the available spectrum resources in the U.S. We look forward to offering innovative new products and services in this new shared CBRS spectrum.”
