SUNNYVALE, Calif., Feb.19, 2013 /PRNewswire/ --Ruckus Wireless, Inc. (NYSE:
RKUS) announced today its new ZoneFlex™ 7982 Smart Wi-Fi access point (AP)
took top marks in a unique, non-vendor sponsored, enterprise Wi-Fi stress test
study performed and published by Wireless LAN Professionals, Inc., (WLAN Pros)
based in Orem, Utah.

Unlike many common industry Wi-Fi performance tests, WLAN Pros set out to
determine how much traffic was needed to "break" access points from nine of
the industry's leading enterprise suppliers including: Aruba Networks,
Aerohive, Cisco, HP, Juniper, Meraki, and Ruckus Wireless.

"With so many new Wi-Fi devices with which to contend, organizations are now
demanding a well-performing wireless network and are, at times, confused and
misled by vendor claims," said Keith Parsons, a certified network engineer and
managing director of Wireless LAN Professionals. "Our ultimate goal was to
keep everything constant and the tests repeatable by only changing the access
point. This way we could determine the edge at which these 'best in class'
access points fall over."

Parsons emphasized that for this wireless testing, no donations, gifts or
money were accepted from any vendor. All participating vendors were encouraged
to and many did actively participate in the testing of their products. WLAN
Pros purchased all the testing equipment. 30 different volunteers representing
five school districts, two universities, seven WLAN AP vendors, and four
competing resellers assisted Wireless LAN Professionals during their testing.

"To make the test as vendor independent as we could, we adapted the testing to
ensure no single vendor had any advantage," said Parsons. "For instance, we
moved the test AP location to not be centered over iPads so Ruckus adaptive
antennas and interference rejection wouldn't give them an unfair advantage."

Stress Test Details

The testing, performed at a Canyons School District facility, involved
stressing Wi-Fi access points by running high-definition unicast IP-based
video streams to dozens of Apple iPads while transferring a 600MB file (up and
down) and performing a 20 second iPerf TCP test to an Apple MacBook Pro over
the same access point under test. WLAN Pros chose 20MHz wide channels, forcing
vendors to work within a smaller RF spectrum.

The dual-band (2.4 and 5GHz) testing involved incrementally adding 5 iPads to
the access point under test until more than 50 percent of the iPads were
counted as "dead" or the FTP estimate exceeded 20 minutes. For each access
point under test, WLAN Pros measured TCP throughput and iPad video errors
(having to restart the video streaming to the device).

Ranking the Results

WLAN Pros Wi-Fi Stress testing involved each iPad supporting a video stream
while concurrently uploading/downloading files as quickly as possible in the
background. The goal was to hold all things constant, only changing the
AP.After completing all the testing of supplier access points, WLAN Pros
ranked cumulative results of each vendor's product based on:

  oThroughput ranking - Established those APs that had the best aggregate TCP
    throughput scores. This represents the total number of bytes
    transmitted—both upload and download for an FTP site added to an iPerf
    download, divided by the total time.
  oiPad video errors ranking - Showed which APs were better at keeping iPads
    playing videos with the fewest errors possible while the Wi-Fi environment
    was crowded with other data traffic. Volunteers connected to an SSID,
    started a browser session and watched video streams. Errors were counted
    if the volunteer had to restart the video on any iPad during the streaming
  oOverall combination ranking – This was equally weighted between the
    throughput ranking and iPad video errors ranking, representing what was
    the overall best balanced AP.

Who Won, Who Lost?

According to Parsons, the most important part of the tests were the lessons

  oIt is possible to run into the limits of available RF spectrum.
  oAccess Points are not all the same.
  oWi-Fi is a shared medium network device, like a hub, not like a switch.

According to WLAN Pros, as each AP neared the maximum utilization of the RF
spectrum, all of the tested APs failed.The differences between the APs were
determined by how well they managed "air time."

While winners and losers varied from test to test, the overall results of the
WLAN Pros testing showed the Ruckus ZoneFlex 7982 outperforming all other
devices under test in each ranked area.

The Ruckus ZoneFlex 7982 was the only access point able to support 25
concurrent unicast HD video streams to 25 individual iPads - delivering the
highest overall aggregate throughput and lowest number of iPad video errors
compared to all wireless access points tested.

"Because Wi-Fi is a shared medium, the key to good performance, as we found
with our testing, was the ability for any access point to optimize the
available spectrum in real time," said Parsons.

The Ruckus ZoneFlex 7982

The Ruckus ZoneFlex 7982 incorporates adaptive antenna arrays for up to 4
times extended range and coverage, and automatic interference mitigation
optimized for high-density environments. It provides dual polarized adaptive
antenna arrays with 21 antenna elements and over 3,000 antenna patterns for

The ZoneFlex 7982 is currently the only three-radio, three-stream, dual-band
802.11n access point to combine dynamic polarization diversity with adaptive
antenna arrays to give customers unmatched improvements in Wi-Fi performance,
signal gain and reception. The ZoneFlex 7982 was also recently awarded
top-marks as the best 3x3 dual band 802.11n Access Point by Syracuse
University, who performed extensive, competitive, multi-client, multi-AP
testing in real classroom environments. Results for that can be found at
