The Mobile Operator Challenge
Operators are responding with a number of measures, including extensive LTE deployments, spectrum acquisition and refarming, backhaul upgrades, movement toward more usage-based pricing, and in increasing numbers, extending their radio access network strategy with Wi-Fi and small cells.
Each of these approaches has its strengths and weaknesses. LTE provides a signicant advance over 3G performance for broad coverage, but its use in high- density applications is challenged by inter-cell interference and siting constraints. Suitable new spectrum is scarce, expensive, and takes a very long time to secure.
Enhancing RAN capacity with Wi-Fi has a number of advantages. Nearly all smart mobile devices support Wi-Fi today, and in fact a growing proportion (particularly tablets) rely on Wi-Fi as their only network connectivity option. Most subscribers expect to nd Wi-Fi in public venues now, whether from their primary service provider, a resurgent community of hotspot providers, or the venue itself.
For operators, Wi-Fi’s shorter range, high throughput, access to as much as 600 MHz of spectrum, and lower unit costs drive higher capacity per dollar of capex in high- density applications than LTE can reach (see gure 1). Finally, Wi-Fi’s time-to-market advantage over LTE small cells allows operators to seize the initiative immediately in the intensifying land grab for deployment rights in high-density locations.

The Solution – Ruckus SCG200
The Ruckus SmartCell Architecture combines the industry’s broadest and highest-performing radio portfolio with the SmartCell™ Gateway 200 for unrivaled scale and flexibility in cellular integration. Ruckus’s end-to-end solution leads the field in addressing each of the key requirements for truly successful carrier-class Wi-Fi, at last giving the technology a long-term role as a full peer to 3G/LTE in the mobile operator’s RAN strategy toolbox.
Powered by the unique BeamFlex adaptive antenna technology and a host of smart, self-organizing network behaviors, Ruckus’s access points (APs) and small-cell backhaul solutions deliver the ultimate in radio performance in challenging high-density applications.
Through Ruckus’s leadership in both developing and implementing the standards work in process at the Wireless Broadband Alliance, the Wi-Fi Alliance, and 3GPP, the complete solution delivers on the promise of seamless subscriber experiences, leveraging the Hotspot 2.0 initiative as well as established standards such as 802.1x.
TheSmartCell Gateway 200 (SCG) offers the unique combination of a massively scalable WLAN controller architecture — supporting 10,000 APs and 100,000 active subscribers per 2U chassis — along with the interface flexibility required to support full integration into the mobile packet core via the 3GPP standard for trusted WLAN access. The SCG 200 also supports the multitenancy features required for inter-operator wholesaling and neutral-host deployments.
The portfolio is completed by a rich EMS and analytics platform developed through our work with several of the world’s largest carrier Wi-Fi deployments to date, including KDDI, Time Warner, and Sky.
NFV-based WLAN Controller Designed for Service Providers and Enterprises
Ruckus virtual SmartCell™ Gateway (vSCG), is a Network Functions Virtualization (NFV) based WLAN Controller for service providers and enterprises who desire a carrier-class solution that runs in the cloud. It supports all of the WLAN Controller features of the industry leading SCG-200, while also enabling the rollout of highly scalable and resilient wireless LAN cloud services.
The vSCG is primarily intended for deployment by a managed services provider in their data center and under their control. It enables the service provider to deploy a very scalable, resilient, and fully featured offering that is backed by their service level agreements. This differentiates it from the many controller-less services that are being offered by vendors.
Complete reporting and analytics engine purpose built for carrier grade and enterprise Wi-Fi Infrastructure
Ruckus SmartCell™ Insight (SCI) is the industry’s first Big Data Wi-Fi analytics and reporting engine purpose built to help enterprises and service providers make informed business decisions regarding the operation of their Wi-Fi networks. It makes use of Big Data technology and storage innovations found in columnar database repositories, which greatly enhance the scale and performance of a system when used to process historical data.
The Ruckus SCI platform transforms traditional network reporting into a vital business tool, collecting, analyzing, parsing, presenting, and storing unprecedented amounts of user, traffic, session, and location information. Data from the largest networks can be stored and retrieved for 5 to 7 years, or more.
Armed with such a vast repository of data and analytics, service providers can now quickly and easily determine, like never before, who is on their Wi-Fi network, what they are doing, when they are doing it, and from where. This can be extended to provide location-based analytics and application recognition both of which will greatly enhance the value of this kind of technology.
SCI gathers real-time and historic data which is analyzed and graphically displayed in an easy to understand format with a wide variety of views and customized reports. The data gathered by Ruckus SCI details essential network statistics such as traffic usage, client and session measurement, network changes, network latency, and inventory.
