Designing Wi-Fi forLarge Public Venues (LPV)such as stadiums, arenas, or convention centers requires a highly strategic RF approach to handleextreme client densityanddynamic environmental factors.

According toRUCKUS One Online Help – High-Density Design Best PracticesandRUCKUS AI Documentation – LPV Deployment Planning, three critical considerations are:

Expected number of devices (B):Determines AP count, bandwidth capacity, and airtime utilization. LPV environments often exceed one device per seat, requiring precise capacity planning.

Effect of human bodies on RF propagation (D):Human absorption of 2.4 GHz and partial reflection of 5 GHz signals dramatically affects coverage. RUCKUS recommends directional antennas and elevated AP placement to overcome this.

Versions of iOS and Android (F):Client device capability (e.g., Wi-Fi 5/6 support, roaming features) influences channel width, band steering, and roaming design.

Other factors like WAN speed and charging stations are operational but not primary design variables in LPV RF engineering.

Auto Cell Sizing (ACS)is a RUCKUS feature designed to automatically optimize the RF environment by dynamically adjustingtransmit power levelsof access points to ensure balanced coverage and minimal interference between APs.

According to theRUCKUS One Online Help – RF Management and Auto Cell SizingandRUCKUS AI documentation – RF Optimization Tools, ACS:

Automatically adjusts radio transmit power (B)based on environmental conditions and neighboring AP coverage.

Requires background scanning to be enabled (D)so the system can measure the surrounding RF conditions and interference patterns.

ACS doesnot automatically adjust channel selection, as that functionality is handled byChannelFly, a separate RUCKUS technology. It isnot enabled by default, and manual power tuning is typically disabled when ACS is active, since the controller manages power dynamically to maintain optimal cell overlap.

Thus, the correct answers areB(it can automatically adjust radio power) andD(it requires background scanning to be enabled).

ARUCKUS Application Policyallows administrators to control network performance and user experience by classifying, prioritizing, and managing traffic based on the type of application detected on the network.

According toRUCKUS One Online Help – Application Control and Policy Management, andRUCKUS AI documentation, Application Policies can:

Apply rate limiting (A):Control the bandwidth allocated to specific applications or application groups (e.g., limit video streaming or social media traffic).

Apply Quality of Service (E):Mark or prioritize application traffic using DSCP or internal QoS levels to ensure latency-sensitive applications such as voice or conferencing receive higher priority.

RUCKUS leveragesDeep Packet Inspection (DPI)for identifying over 2,500+ applications, enabling precise enforcement per SSID or per user.

Other options—URL filtering,VLAN assignment, andpacket capture—are handled through separate mechanisms (Web filtering, Device Policy, and diagnostic tools, respectively), not via Application Policies.

Therefore, the correct answers areA (Rate limiting)andE (Quality of Service).

SmartZone controllerssupport a range ofexternal authentication servicesfor bothproxy (via controller)andnon-proxy (direct-to-AAA)authentication mechanisms. According to theRUCKUS One Online Help – Authentication Services Configuration, the supported external services include:

Active Directory (AD) (A):Used for domain-based user authentication and group policy enforcement.

Lightweight Directory Access Protocol (LDAP) (B):Provides user authentication through directory lookup, commonly used for enterprise identity systems.

RADIUS (E):A widely used AAA protocol that integrates with external servers such as FreeRADIUS, Cisco ISE, or Microsoft NPS for centralized authentication and accounting.

WhileSAMLandOAuthare used inRUCKUS Cloud and RUCKUS Onefor SSO (Single Sign-On) and API authentication, they arenot used for WLAN or AAA authenticationwithin SmartZone.TACACS+is not supported as an external client authentication method in SmartZone (it is only used for admin login on some platforms).

Therefore, the correct authentication services areA (AD),B (LDAP), andE (RADIUS).

RUCKUS Wi-Fi Planner (Wi-R Planner)is a predictive design tool that helps plan AP placement and coverage before physical deployment. It relies on environmental and hardware data to simulate accurate RF propagation.

According toRUCKUS One Online Help – Wi-Fi Planner Configuration, essential inputs include:

AP model selection (A):Determines transmit power, antenna gain, and coverage pattern.

Building wall materials (C):Define RF attenuation and signal propagation characteristics.

Parameters likeDHCP/DNS settingsorcontroller cluster sizeare not required for predictive modeling—they’re part of post-deployment configuration.

Thevirtual SmartZone Essentials (vSZ-E)controller provides centralized management for up to10,000 APs and 1,000 switches, making it ideal for large distributed enterprises that prefer self-hosted or cloud-based control.

According toRUCKUS One Online Help – SmartZone Essentials Overview, vSZ-E offers:

(B)Scalability to meet medium-to-large enterprise requirements (well above 3,000 employees).

(C)Centralized management for Wi-Fi and wired networks, including policy enforcement and firmware control.

(D)Cloud-hosted deployment capability, including operation in environments such asAWS,Azure, orVMware.

UnlikevSZ-H, vSZ-E does not supportmulti-tenancyorPartner/Administrative Domains, and it does not natively tunnel user data back to the cloud; data is locally bridged unless configured via GRE or VPN.

AnEthernet Port ProfileinSmartZonedefines wired interface behavior and port settings for access points that have multiple Ethernet ports. These profiles are used to configure connectivity, security, and redundancy on wired links between APs and the upstream network.

According to theRUCKUS One Online Help – AP Ethernet Port ProfilesandSmartZone 5.x Configuration Guide, the following parameters are supported:

Port Speed (A):Defines link negotiation—Auto, 10/100/1000 Mbps, or fixed rate.

Spanning Tree Mode (D):Controls loop prevention through STP configuration on AP Ethernet ports.

802.1X Authentication (E):Enables port-based authentication for secure wired access on AP Ethernet interfaces, commonly used in hospitality and MDU deployments.

Other listed options—LAG creation(handled via controller-side link aggregation configuration),number of clients(a WLAN-level setting), andTunnel Profile selection(handled under WLAN or Zone configuration)—are not part of the Ethernet Port Profile feature.

Thus, the correct answers areA (Port speed),D (Spanning Tree mode), andE (802.1X Authentication).
