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.



OpenG 是 Ruckus 提供的一项技术创新,可在传统宏观网络连接困难的室内环境扩大移动网络覆盖范围和容量。该技术集全新的辅助频谱共享 (CSS) 功能和 small cell 技术于一身,可将经过许可的移动网络连接引入室内环境。在美国,OpenG 解决方案使用联邦通信委员会制定的公民广播无线电服务 (CBRS) 规则中提供的 3.5GHz 频谱。Ruckus 是无线行业 CBRS 解决方案研发、营销和推广领军企业大军中的积极参与者。(按此查看相关发布内容。)


移动网络服务一直以来都是采取二者选一的策略:用户在户外连接移动宏观网络,而在移动网络信号较差的室内环境就要依赖 WiFi。如果您曾经在使用手机进行通话的过程中走入办公楼或停车场,您就会了解这一问题的重要性。在许多建筑物中,尤其是新建的建筑,通过许可的无线电频谱提供服务的移动网络信号根本无法渗透至用户需要的所有位置。尤其是建筑物的深入空间,您看到的只能是移动信号的“盲区”、掉线和痛苦不已的用户。

LTE-WiFi 结合技术和 CSS 的兴起改变了一切。通过 Ruckus 提供的 OpenG 等诸如此类的解决方案,服务提供商和企业可以在室内环境部署“中立主机” small cell 解决方案,以便将移动网络连接延伸至其自身无法触及的地方。结果:更好的室内覆盖,用户更加满意,托管无线服务获得新的商业机会。
