OpenG is an exciting new Ruckus technology innovation that can vastly improve mobile coverage and capacity inside buildings. It utilizes shared spectrum on the CBRS band and enables venues to deploy an LTE network with the simplicity of Wi-Fi. This is a new business opportunity for all Service Providers, enabling them to deliver to enterprises & venues in-building cellular LTE coverage (no spectrum ownership required!).

Below are answers to a few questions concerning OpenG.

Ruckus In-building wireless

Q: What is the in-building cellular challenge?
A: Macrocellular radio signals attenuate as they pass through the fabric of a building, resulting in dead zones, where there is no coverage at all or only intermittent coverage which creates the in-building cellular challenge. This results in poor cellular performance, meaning disruption in service, for anyone using a cell phone in-building.

Q: What is OpenG technology?
A: OpenG technology combines coordinated shared spectrum capabilities, such as 3.5 GHz in the U.S., with neutral host capable small cells to enable building owners of all sizes to deploy cost-effective in-building cellular coverage for all of their customer and employee needs. Ruckus’ vision offers a significantly less expensive, easier-to-deploy, mobile network-neutral alternative to distributed antenna systems (DAS) and traditional small cells.

Q: Why is this important to the industry?
A: The industry is in the midst of a dramatic shift as cellular and Wi-Fi technologies converge. This convergence is taking on multiple forms, including cellular adopting attributes of Wi-Fi (LWA, LAA), Wi-Fi adopting attributes of cellular (Wi-Fi calling, Hotspot 2.0) and lines blurring between traditional spectrum management models (either licensed or unlicensed) with the new coordinated shared spectrum 3.5 GHz model adopted by the FCC in the U.S. Enterprises and service providers are seeking solutions that support subscribers from all mobile networks. These solutions are easy to deploy and provide an attractive total cost of ownership (TCO) while improving in-building performance.

Q: How will voice over Wi-Fi work with OpenG?
A: The same as it does now.

Q: Is this US centric?
A: OpenG is a global opportunity; it is not U.S. only. Citizens Broadcast Radio Service, or CBRS, refers to the new rules the U.S. FCC adopted, opening 150 MHz of spectrum (3550-3700 MHz) for commercial use in the U.S. Throughout the world, regulatory bodies are also expected to adopt similar rules for CBRS-like spectrum in their respective countries. These may use 3.5 GHz spectrum, or they may use other spectrum bands—it depends on what each country has identified previously for CBRS-like services.

Q: What is the value proposition to mobile operators?
A: MNOs get a massive footprint expansion at little to no cost. OpenG will fix coverage problems and requires no change to the operators’ core network.


What it means:

OpenG is a Ruckus technology innovation that improves mobile coverage and capacity inside buildings, where connecting with conventional macro networks is a challenge. It combines new coordinated shared spectrum (CSS) capabilities with small cell technologies to bring licensed mobile connectivity indoors. In the United States, OpenG solutions use 3.5GHz spectrum under the Citizens Broadcast Radio Service (CBRS) rules defined by the Federal Communications Commission. Ruckus is an active participant in a group of wireless industry leaders working to develop, market and promote solutions utilizing CBRS.

Why you should care:

Mobile service has traditionally been an either/or proposition: users connect to mobile macro networks outside, and rely on Wi-Fi indoors where mobile signals are poorer. If you’ve ever been on a mobile call and walked into an office building or parking structure, you know why that’s a big problem. In many buildings, especially new construction, mobile services that operate over licensed radio spectrum just can’t penetrate everywhere users want them. Especially deep inside buildings, you end up with mobile “dead zones”, dropped calls and frustrated subscribers.

With the emergence of LTE-WiFi convergence and CSS, that’s all changing. Solutions like Ruckus’ OpenG let service providers and enterprises deploy “neutral host” small cell solutions inside buildings to extend mobile connectivity to places it wouldn’t otherwise reach. The result: better indoor coverage, happier users and new business opportunities for managed wireless services.
