Meru WLAN System vs. Cisco
Systems WLAN Solution for
Converged Voice and Data Wireless Networks
Release date:
18 September 2007
Document Number:
207214
Meru Networks commissioned The Tolly Group to evaluate the Meru Wireless LAN system which consists of a WLAN controller and one or more APs. For this test, engineers paired Meru’s midsize enterpriseclass controller, the MC3000, with its dual radio, 802.11g WLAN AP208 Access Point.
Engineers measured the voice quality and aggregate throughput in a single AP environment handling several dozen simultaneous live and simulated VoIP-over-WLAN sessions along with simulated traditional data applications. Tests focused on showing the benefits of Meru’s over-the-air voice Quality-of-Service versus a Cisco Systems, Inc. 4402 WLAN controller and AP1242AG in high-density scenarios. Tests were conducted in July 2007.

Metalink, Ltd. WLANPlus™ MtW8171/MtW8151 Chipset Competitive 802.11n (MIMO) Wireless LAN Performance for Homes
Release date:
08 August 2007
Document Number:
207215
Metalink, Ltd. commissioned The Tolly Group to evaluate its dual-band (2.4 GHz / 5 GHz) wireless solution based on Metalink’s dual-chip WLANPlus MtW8171 / MtW8151 chipset in a reference platform.
Tests compared the throughput and coverage area benefits obtained in a home environment with Metalink’s solution against three similar chipsets from Atheros, Broadcom and Marvell.
The competitor chipsets were installed in off-the-shelf products from Apple, Inc., Linksys Corp. and Buffalo Technology, Inc., respectively. The Tolly Group tested the indoor wireless
performance of all products in various areas of a three-story house in Atlanta, GA. Tests were conducted in July 2007.

White Paper Sponsored by Siemens: Evaluating Wireless IPS Systems
Release date:
18 April 2006
Document Number:
206119
This Tolly Group white paper, commissioned by Siemens, focuses on the key issues users must consider when evaluating wireless intrusion prevention systems. For the report, The Tolly Group evaluated HiPath Wireless Manager Advanced (HWMA), a multi-faceted WIPS designed to protect enterprise network infrastructures from wireless attacks.
The Tolly Group assessed the capability of HWMA to detect and block a range of wireless threats — from dealing with rogue APs, to detection and prevention of access point (AP) MAC address spoofing, to detection and prevention of Denial of Service (DoS) attacks, and several others.
Tolly Group engineers measured the effectiveness of HWMA against two other products: AirMagnet Inc.’s AirMagnet Enterprise and Aruba Networks Aruba Mobility Controller. Tests were conducted at AirTight Networks facilities in Mountain View, CA during December 2005.

Fortress Technologies, Inc. Fortress Security Controller FC-X Encryption and Compression Performance Evaluation of Three Models (FC-1500, FC-500 and FC-250)
Release date:
20 March 2006
Document Number:
206104
Fortress Technologies commissioned The Tolly Group to evaluate the performance of the company’s flagship FC-X Security Controller. The Fortress FC-X is a high-performance security appliance with Gigabit Ethernet interfaces and is an integral part of the Fortress Security System designed to provide high performance, secure and reliable connectivity to wireless LANs and fixed wireless networks using Wi-MAX, free space optics, satellite, or other point-to-point links.
The Tolly Group conducted steady-state zero-loss (<0.001%) encryption and compression throughput and latency tests in two FC-X boxes for a variety of Ethernet frame sizes. The FC-X also was subjected to extensive performance tests designed to measure the scalability of the FC-X Security Controller in three selectable performance modules: FC-1500, FC-500 and FC-250.
Finally, The Tolly Group measured the zero-loss throughput in Mbps across the FC-X pair on an encrypted link for different data types (most-compressible traffic and least-compressible traffic) and various numbers of emulated clients for the three FC-X models. For the latency test, The Tolly Group measured the average Store-and-Forward latency for the least-compressible data type and a single client for the FC-1500 model only.

Symbol Technologies Wireless Switch System 5000
802.11b Performance Evaluation versus Cisco Systems Aironet 1220 Access Point
Release date:
16 February 2004
Document Number:
204100
Symbol Technologies commissioned The Tolly Group to evaluate its Wireless Switch System, which is comprised of the WS 5000 Wireless Switch and one or more AP100 Access Ports. The WS 5000 is a switch that centralizes unified access, security, policy management and Quality of Service for the wireless network, while the Access Port consists of the wireless LAN radio and antenna. This design represents a ‘skinny’ approach to wireless in which the intelligence usually reserved for access points is relocated to a centralized switch and the Access Port handles radio functions only.
Tolly Group engineers tested the WS 5000 and Access Port against a Cisco Systems Aironet 1220 Access Point, which represents a ‘fat’ AP design in which intelligence is located in the access point.
Engineers measured the raw throughput and latency of devices under test using Chariot software. A multi-BSS performance test proved the performance advantages of assigning multiple BSSIDs against a single BSSID while implementing virtual WLANs. Another test measured the throughput with virtual WLANs enabled and in the presence of background broadcast traffic. Engineers also validated the security options available in both the systems and The Tolly Group validated the Symbol Wireless LAN System’s QoS facilities by prioritizing traffic by application or by WLAN.

Aruba Wireless Networks Aruba 5000 Wi-Fi Switch/Aruba 52 Access Point - Encrypted Wireless Performance
Release date:
23 October 2003
Document Number:
203126
Aruba Wireless Networks commissioned The Tolly Group to evaluate its Aruba 5000 Wireless LAN Switch and its Aruba 52 access point. The Aruba 5000 is a four-slot WLAN switch with an integrated VPN gateway that operates at 10/100/1000 Mbps and combines firewall and VPN functionality along with wireless service. The Aruba 52 access point is a dual-band AP that supports 802.11a (54 Mbps) and 802.11b (11 Mbps).
Engineers conducted an IPSec throughput test designed to measure the aggregate internal performance of the Aruba 5000 switch. A second test measured the real-world throughput of the Aruba 5000 with an integrated VPN gateway supporting a large-scale wireless client/server network. Lastly, Tolly Group engineers validated 20 different features of the Aruba 5000 WLAN switch and the Aruba 52 AP. All tests were performed in September 2003.
