Ruckus said that the nature of high-density environments, where thousands of simultaneous users must be supported in a confined space, presents a unique set of challenges that conventional, enterprise Wi-Fi systems simply aren’t able to handle.
The requirements for high-density environments run counter to traditional enterprise wireless LAN (WLAN) deployments. Instead of optimising for broad Wi-Fi signal coverage with the fewest number of access points, Wi-Fi networks within stadiums and other high-density environments require large numbers of access points (APs) to get the needed capacity and very high spectral reuse.
When large numbers of APs are deployed in close proximity, it creates the potential for interference. Ruckus BeamFlex adaptive antenna technology is ideally suited to this kind of environment as it enables RF energy to be focused at the user.
This increases the signal gain, which provides for a much better user experience. It also reduces the radio frequency (RF) energy that neighbouring APs might see, which provides for greater interference mitigation.
Ruckus provides a line of ZoneFlex 7782 3x3:3 2.4/5GHz 802.11n APs with 120º sectorized and 30º narrow beam antennas, which are especially effective in stadiums when APs are mounted high above the crowd, as the narrow beam limits the coverage area.
By limiting the coverage area, the opportunity for interference is also limited. Other technologies that can be essential in any high-density deployment are approaches that enable automatic channel selection.
Ruckus ChannelFly technology enables the AP to automatically pick the optimum 2.4 or 5 GHz channel, and when circumstances change, the AP can quickly select another channel.
The RF characteristics of a venue tend to change greatly with the presence of a crowd, and when that crowd ebbs and flows, the optimum channel selection may change. Having all APs operating on the optimum channel can improve overall network performance.
Salt Lake City’s Rio Tinto Stadium
Rio Tinto has 100 Ruckus APs deployed, a combination of Ruckus ZoneFlex 7782-N (narrow beam) outdoor APs, which are mounted on the catwalks above seating areas, and dual-band Ruckus ZoneFlex 7363 indoor APs that provide coverage in the concourses, press boxes, and business offices.

To conduct an initial trial, eGear installed 30 Ruckus ZoneFlex 7962 indoor APs and one on-site Ruckus ZoneDirector 1000 controller to manage the network. The Ruckus Smart Wi-Fi infrastructure was able to support upwards of 1,600 concurrent users and roughly 4,000 devices, consistently delivering 27 MBps uplink and 40 MBps downlink connectivity.
Kansas City Convention Center
After an extensive site survey, ETI designed a wireless network with the Ruckus ZoneFlex system to both meet the Convention Center’s current needs and satisfy their requirements well into the future. The network at K.C.C.C. includes approximately 120 Ruckus ZoneFlex 7962 indoor access points—100 of which are hard-wired, and 20 that are deployed in a configuration leveraging Ruckus SmartMesh Networking. A Ruckus ZoneDirector 3000 centralized controller provides centralized management and administration of the Wi-Fi infrastructure.
