Ruckus ZoneFlex Ranks Highest in New Independent Tests of Seven Leading Enterprise Wireless LAN Systems by Jones-Petrick and Associates

Ruckus ZoneFlex System Demonstrates Nearly Three Times TCP Throughput over

Competitive Systems, Exhibiting Superior Handling for Voice and Data in the

Hardest to Reach Areas

    SUNNYVALE, Calif., Jan. 14 /PRNewswire/ -- Ruckus Wireless today
 announced that its ZoneFlex(TM) Smart WLAN system outperformed seven
 leading enterprise wireless LAN (WLAN) systems in an independent test
 report published by Jones-Petrick and Associates (JPA), one of the
 industry's most respected experts in wireless networking.
     The WLAN testing, conducted over a two-month period, benchmarked the
 latest generation of enterprise WLAN systems within a real-world office
 environment. The tests measured single client throughput, multiple (20)
 client throughput and voice quality performance with multiple (19)
 Voice-over-WiFi (VoFI) clients and background data traffic at varying
 distances, levels of obstruction and interference.
     In every test, the Ruckus ZoneFlex consistently delivered significantly
 higher throughput at the greatest distances and in the most challenging
 locations, with and without interference.
     Additionally, in the VoFI tests, ZoneFlex demonstrated the highest and
 most consistent voice quality, measured by mean opinion score (MOS) and
 R-Value -- two standard performance metrics for evaluating VoIP
 technologies -- across all the test locations, making it the only WLAN
 system able to continuously deliver "toll quality" voice traffic.
     The wireless testing was performed by Al Petrick, the vice chairman of
 the IEEE 802.11 working group and co-author of the book IEEE 802.11
 Handbook, A Designer's Companion. Mr. Petrick is widely considered a Wi-Fi
     "The innovations in centralized wireless LAN systems have enabled
 enterprises to deploy, manage and secure their WLANs to mobilize the
 workforce and reduce overhead costs associated with constant wiring and
 re-wiring," said Al Petrick, principal of Jones-Petrick. "However, when it
 comes to delivering reliable, predictable performance for users everywhere,
 our testing shows that systems with inherent, RF-optimized APs outshine
 those that rely only on WLAN controllers for RF management.
     "With Wi-Fi now becoming users' preferred connectivity method,
 enterprises are looking for systems that can deliver wired-like
 performance, particularly in hard-to-reach locations and for
 delay-sensitive applications like voice and video. Based on our testing, we
 determined that the performance benefits offered by the Ruckus ZoneFlex
 system, combined with its centralized management tools, make ZoneFlex the
 ideal solution for the mid-size enterprise," Petrick concluded.
     As the centralized WLAN model becomes accepted as the de-facto standard
 for enterprise WLANs, the focus will turn to fixing the neglected RF issues
 that negatively affect performance and stability. The historical approach
 of throwing more APs and controllers into the network to address range and
 performance limitations increases WLAN cost and complexity, in addition to
 being ineffective in combating RF interference.
     "The biggest complaints we hear from companies aren't about deployment,
 management or security any more. They are about RF problems -- poor
 coverage, unstable Wi-Fi signals, and sporadic drops in Wi-Fi performance,"
 said Selina Lo, president and CEO of Ruckus Wireless. "JPA's test results
 show how important RF-optimized APs are to overall system performance and
 stability. The technical advances we've made are paving the way for
 wire-class Wi-Fi."
     Test Details and Results
     JPA conducted a variety of wireless LAN tests in a single-story,
 18,000-square-foot office complex in Fremont, California, using the latest
 equipment from seven leading enterprise WLAN vendors and standardized test
 tools such as Ixia's IxChariot and IPerf.
     For each device under test, JPA tabulated TCP throughput results for
 both single client and multiple clients in different locations throughout
 the test facility, with and without interference. JPA also captured the MOS
 and R-Values in a VoFI test with multiple dispersed VoFI clients and
 varying AP locations. The tests performed were:
1) TCP downlink performance on a single client in six different locations with four client rotations per location, with and without interference introduced 2) Aggregate TCP downlink performance on 20 dispersed clients and six AP locations at varying distances, with and without interference introduced 3) Voice quality of 19 VoFI clients and 1 client PC generating background data traffic Ruckus Wireless, the Clear Winner JPA's WLAN testing determined that the Ruckus ZoneFlex system performed better than all leading alternatives in providing extended range, consistent performance across all locations, support for multimedia and the ability to automatically adapt to environmental changes caused by interference and other obstacles. Highlights of the test results include:
-- The Ruckus ZoneFlex system continually demonstrated significantly higher TCP throughput at the farthest and most challenging locations. -- With ZoneFlex, an 802.11g Centrino client exhibited 2.5x higher average TCP throughput when positioned 175 feet from the Ruckus AP, than any other product tested. -- At the furthest distance, Ruckus ZoneFlex delivered 15.66 Mbps of aggregate TCP throughput to 20 clients, nearly 3x more than that of the nearest competitor. -- In single 802.11g client testing, ZoneFlex exhibited the highest average TCP downstream throughput across all locations. -- In VoFI tests, Ruckus ZoneFlex achieved the highest quality MOS (4.33) and R-Value (90.47) scores across all locations over all competitive systems. Ruckus' "smart Wi-Fi" technology, which is based on a multi-antenna array, enables real-time signal path selection and interference rejection, resulting in a consistently reliable connection -- even for high-bandwidth applications and in challenging environments.
