Overview:
The Industry's Most Scalable and Versatile Small Cell Gateway
Specially designed for mobile service providers, the SmartCell Gateway 200 (SCG-200) is the industry’s first multi-function HetNet small cell gateway. Situated between the Wi-Fi network and the mobile core, the edge services platform integrates all the essential network element functions required for seamless Wi-Fi/mobile network integration and management, including:
- Large Scale Access Point Controller
- Wi-Fi Gateway
- 3G/4G Offload Gateway
- Automatic Client Provisioning
Situated at the edge of operators' mobile networks, the SmartCell Gateway 200 represents the first in a new category of scalable and versatile service platforms to eliminate the difficulties operators are experiencing with building and managing large-scale small cell networks and integrating them into their mobile core.
Awarded the "Best Mobile Broadband Technology" by the GSMA, the RUCKUS SmartCell Gateway (SCG) is capable of supporting hundreds of thousands of RUCKUS or non-RUCKUS Wi-Fi access points and hundreds of thousands of clients, as well as providing standardsbased 3GPP integration into existing 3G and future 4G/ LTE mobile core infrastructures.
The SCG serves both SIM and non SIM-based clients using cellular friendly authentication protocols, such as 802.1X. Combined with policy-based data traffic steering, operators have the option to offload traffic at the Wi-Fi edge or tunnel the data traffic to the service provider's core (PDG/TTG mode). With this approach, operators can transparently accommodate today's mobile devices (UEs) without installing special client software (clientless solution) thereby accelerating the time-to-market and adoption of Wi-Fi based offloading solutions.
The SCG platform features a unique NEBS-3/ETSIcompliant, dynamically scalable clustering model that maintains carrier-class availability and resiliency through active-active clustering by incorporating a distributed and replicated database optimized for real-time data management.

Unrivaled Scalability and Versatility
Unlike solutions that were originally designed for smallerscale private enterprise Wi-Fi networks, the new RUCKUS SCG platform has been developed specifically to meet the unique requirements of very large-scale access point management in carrier environments, providing all of the essential network element functions required to support the multiple integration architectures dictated by the realities of network operator infrastructures and mobile device capabilities.
Wi-Fi Gateway
In the Wi-Fi domain, the SCG acts as a very large-scale access point controller and Wi-Fi gateway combined, managing both RUCKUS access points and third-party access points. When working with RUCKUS access points, the SCG provides featurerich management — including control over their self-organizing smart networking behaviors such as RF management, load balancing, adaptive meshing, and backhaul optimization. The SCG allows operators to dynamically configure and manage network and subscriber QoS/policy rules, in addition to authorize, account and bill Wi-Fi users enabling monetization of Wi-Fi services.
3G Data-Offload Gateway
The SCG provides true 3G data offload functionality working across 3GPP control and data planes. The platform supports a clientless architecture option that does not require any client software. Based on 802.1x, GRE, and GTP, this innovative clientless approach to TTG/PDG functionality provides seamless integration into existing mobile core architectures and is compatible with a much wider selection of today's mobile devices than other Wi-Fi/mobile integration solutions, such as I-WLAN.
The SCG also provides dynamic policy controls to tune Wi-Fi network resource utilization, giving operators the tools to maximize revenue capture while also managing the end user's QoS experience in a consistent manner across both cellular and Wi-Fi access networks.
Unified Authentication
Single-credential authentication, critical to the successful implementation of data offloading solutions, eliminates the complexity of authentication and connection, motivating subscribers' rapid adoption of the carrier's Wi-Fi offer. The SCG implements 802.1X based EAP methods — EAPSIM, EAP-AKA, EAP-AKA' and other EAP variants, along with traditional portal-based authentication schemes — such as WISPr 1.0. The multi-protocol authentication support allows operators to deploy a variety of devices — ranging from SIMbased 3GPP cell phones (UEs), to non-SIM devices such as laptops on the next generation of carrier grade Wi-Fi networks.
Unique 802.1X Smart Tunneling Mode
Enabling Wi-Fi roaming while interworking WLAN with cellular core gives operators as much visibility and control over traffic generated over Wi-Fi networks as over cellular networks. The SCG's unique clientless solution, with the in-band IP assignment from the GGSN/PGW, allows operators to authenticate and tunnel WLAN traffic to either a GGSN or (an LTE) PGW, providing the foundation for session continuity.
Multi-vendor Wi-Fi AP Gateway
The SCG unifies user authentication and data traffic originating from non-RUCKUS access points. This enables a single point where applying network level vendor agnostic policy controls can be applied and key user data KPIs can be generated. It also allows operators to uniformly set policies for traffic steering (offloading), such as offloading at the SCG (PDG mode) or tunneling traffic to the GGSN or PGW. It also provides a single point for generating user data session records for statistical analysis and charging.
Hotspot Services
The SCG supports secure large scale hotspot deployments, long URL lists and walled garden deployments , and is able to handle multiple whitelist/blacklist for HTTP traffic. The SCG's ability to transparently handle static & dynamic proxy HTTP messages minimizes the impact on corporate users utilizing hotspot services with proxy settings on their devices. The SCG's per subscriber API interface allows deploying an external portal server for login/splash screen handling. The SCG also supports WISPr 1.0 based authentication.
Operations and Administration (OAM)
Element Management System (EMS)
With the built-in EMS, the SCG supports rapid deployment of separate and expensive dedicated management systems. The built-in EMS provides user-friendly full-fledged FCAPS support and can be easily integrated with existing NOC/NMS management systems. The integration of management system supports secure API access (RESTful JSON), standards based SNMP MIB access, SNMP traps and CLI based configuration and management, allowing traditional Wi-Fi service providers, cable operators and cellular operators to manage the integrated Wi-Fi networks easily through their existing operation desk.
Statistics, KPIs and Reports
The SCG's built-in EMS provides rich near real-time statistics, ranging from data on on-going operations of APs, SSIDs, Radios, backhaul (Mesh) and the Wi-Fi controller and gateway system (the SCG cluster itself). Reports ranging from hours to years can be generated for a variety of Key Performance Indicators (KPIs) and exported out in multiple formats. For operators seeking richer information, RUCKUS also provides the (optional) Wi-Fi Analytics appliance for long-term storage, sophisticated data mining and analysis, and richer complex reporting, allowing operation teams to leverage dedicated external reporting systems to generate complex reports.
Wholesale/MVNO operations
The SCG's fully functional GUI provides concurrent Rolebased access control (RBAC) for viewing the Wi-Fi system resources and performance. With the support of partitioning for access in a secure manner, the SCG allows Wi-Fi service providers to lease Wi-Fi network resources such as WLANs and APs to other service operators such as MVNOs, to enable MVNO admins to administer and monitor only the WLANs and APs over which they have control.
Charging
The SCG provides billing functionalities for operators to monetize their Wi-Fi network capabilities via basic RADIUS based accounting and generation of session CDRs, which can be transferred to an external Charging Gateway Function (CGF) via the Ga interface. The Charging Data Functionality (CDF) is also implemented in the SCG.
Future Evolution
The SCG has been designed for future technology evolution without requiring costly hardware upgrades; instead, the SCG supports non-disruptive functionality via software upgrades. This software-based upgradable design allows an operator to deploy an SCG as a pure-play Wi-Fi controller today and upgrade the existing SCG for e-PDG functionality at a later point in time, in-line with the operator's timeline for LTE network roll-out and LTE/Wi-Fi interworking plans.
Features:
Large-Scale Access Point Controller
The SCG-200 offers the industry’s most scalable controller architecture, through a unique, dynamically scalable clustering model that maintains carrier-class availability and resiliency through active-active N+1 redundancy and hot-swappable components.

Traffic can be forwarded via:
- Local breakout at the AP to offload the entire Wi-Fi data path from the gateway.
- Secure tunnel from the AP to the gateway with local breakout at the gateway, to offload Wi-Fi traffic from the backhaul and the core network
- Various tunneling options to direct traffic from the data-offload gateway to forwarding gateways in the mobile core
Automatic Client Provisioning
The SCG-200 implements automatic client provisioning technology, allowing popular client devices to be automatically configured for access upon service activation. Subscribers no longer need to sign on explicitly every time they access hotspot services.
