The six companies—Federated Wireless, Google, Intel, Nokia, Qualcomm and Ruckus Wireless - say they believe that CBRS will be critical to drive innovation, support new business models and spur global economic growth.

The declaration by the six companies follows the move last April by the US Federal Communications Commission (FCC) to adopt rules for CBRS which opens 150 MHz of spectrum (3550-3700 MHz) for commercial use.

With the change by the FCC, because spectrum access is actively coordinated based on priority and granular location, it becomes possible for regulators to make previously allocated spectrum available to new entrants and services—while providing necessary protections for incumbent users of the band.

The companies say they aim to build a robust ecosystem of industry participants and make CBRS solutions as widely available as possible, and that operators could benefit from a significantly expanded footprint and capacity on new spectrum, while subscribers could enjoy a consistent wireless broadband experience—particularly in challenging places such as indoor locations, venues and corporate campuses.

Meantime, Ruckus Wireless has said it is its intention to address the challenge of in-building cellular coverage and capacity through the introduction of OpenG technology, which combines coordinated shared spectrum, such as 3.5 GHz in the US, with neutral host-capable small cells to enable cost-effective, ubiquitous in-building cellular coverage.

Ruckus plans to drive the adoption of OpenG technology—which it says addresses a global market with an annual Total Addressable Market (TAM) of over $2 billion—by leveraging its extensive enterprise channels, service provider, public venue and enterprise customer base, and its portfolio of differentiated technologies.

Ruckus is demonstrating OpenG technology in collaboration with Qualcomm during the current Mobile World Congress (MWC) 2016 in Barcelona.
