Document number:
213122
Release Date:
15 Apr 2013
Wireless networking has become the de facto standard endpoint connectivity in the workplace. Now, 802.11ac is the first Wi-Fi technology that can enable wireline performance in a wireless environment. Widespread deployment of 802.11ac could eliminate the need for wired clients of any type (outside of the data center) – enabling “utility networking” for the first time. With the advent of next-generation 802.11ac, users enjoy faster performance and network architects can expect higher client density per AP.
Ubiquiti Networks, Inc. commissioned Tolly to evaluate their next-generation UniFi UAP-AC access point, which leverages the 802.11ac architecture, against three leading 802.11n competitive offerings from Aruba Networks, Cisco Systems and Ruckus Wireless. (The other vendors do not yet offer systems leveraging 802.11ac technology.)The Ubiquiti Networks UniFi-AP AC delivered significantly greater throughput using 802.11ac technology as well as up to 10% greater throughput than the other offerings when running 802.11n (5GHz).

Comparative WLAN Performance and QoS in Media Applications Evaluation
Document number:
212133
Release Date:
14 Jan 2013
The Internet has changed the way users view and use media in the home. A vast majority of consumers use their Internet at home to download, view and distribute media content. In addition, these same users very rarely have only one application or process running on their home network at any given time, which can lead to slow downloads/uploads as other applications use bandwidth needed to deliver a favorable user experience.
The Belkin line of routers uses IntelliStream technology to prioritize traffic and bandwidth, by default, to provide the highest level of performance possible. This technology selectively prioritizes latency-sensitive and high-throughput applications, allowing for a higher quality of experience for media streaming. Belkin commissioned Tolly to evaluate the performance and Quality of Service (QoS) of some of their N-class and AC-class lines of routers versus comparable devices from four leading vendors, denoted in this document as Vendors A, B, C and D.

Motorola WiNG 5 Wireless LAN Solution
Evaluation vs. Aruba Networks and Cisco Systems in Branch Office & Retail Store Deployments
Document number:
212125
Release Date:
16 Aug 2012
Enterprise-class wireless LAN (WLAN) deployments have evolved from being adjunct to the office wired LAN and are now the primary communication medium for many organizations. Increased speeds have made the WLANs capable of carrying heavier traffic loads. In parallel, the dramatic increase of tablet computing and acceptability of bring-your-own-device (BYOD) have increased both the importance of the WLAN and the challenges in managing the environment. As business expands, organizations expect headquarters-class reliability for their branch operations. When business applications are delivered wirelessly, the WLAN becomes a critical element of the branch infrastructure.
Motorola commissioned Tolly to evaluate the Motorola, Aruba and Cisco offerings in several areas especially critical in remote branch office environments. The Motorola solution, built on its WiNG 5 architecture, provided significant benefits over the competing solutions. Motorola’s deployment was less complex and scaled better than Aruba and Cisco, provided significant functionality and security benefits when branch/retail locations were disconnected from the central-site controller and offered WAN prioritization functionality not offered by the others.

Edgewater Wireless EAP3000 Access Point
WiFi3 vs. Single-Channel Access Point Performance
Document number:
212106
Release Date:
14 Feb 2012
Wireless 802.11a/b/g/n LAN (WLAN) Access Points (APs) are integrated with single-channel radio solutions. While these single-channel APs advertise high-speed connectivity to clients, in practice the performance of the network is adversely impacted when a slow client, or when multiple slow clients, connect to the AP.
In cases where older 802.11b clients are being supported, this rate can be as low as 1Mbps when factors like distance or interference prevent higher association rates. Thus, even a single client associated at a low rate will degrade the overall performance of the AP.
The Edgewater Wireless EAP3000 AP eliminates this problem. By providing three separate channels, the EAP3000 can service older, low-speed clients on one channel while providing two additional channels that can be used by newer, high-speed clients.
Tests show that the EAP3000 provides a dramatic increase in aggregate throughput in these mixed-mode environments when compared with single-channel APs from several leading providers.

Cost and Capacity Analysis: Xirrus vs. Aruba Networks and Cisco Systems
Document number:

Release Date:
05 Aug 2011
Network architects considering deployment of Wi-Fi solutions need to be aware that not all 802.11n Wi-Fi products are architected the same, nor do they offer the same level of performance. Customers need to consider various factors like the one-time capital expenditure (CapEx) required for hardware and software components of each solution, as well as the ongoing operational expenditure (OpEx) items such as maintenance and power costs. In addition to the acquisition and ongoing costs associated with each solution, customers need to also factor in the costs of any switching infrastructure upgrades, cabling infrastructure upgrades, etc. required to implement a solution. Apart from these easily-quantifiable costs, there could be ancillary but substantial costs associated with items such as: site surveys, end user training, network performance and coverage optimization that will vary from one deployment to another.
Xirrus Wi-Fi Arrays, available in 4, 8, 12, and 16 radio models, are built on a distributed architecture that provides a level of inherent redundancy and resiliency not found in traditional 2 radio AP + controller solutions. The high-density radio implementation of the Xirrus solution provides for a dramatic reduction in the need for physical devices - 51 Xirrus Arrays to 192 Cisco/Aruba’s Aps in the first example described below. In the simplest terms, this Xirrus advantage translates into lower capital expenditures (CapEx) for hardware, device installation and network infrastructure upgrades and lower operational expenditures (OpEx) for maintenance, support and power consumption.
To illustrate the Xirrus architectural benefits in a way that would be meaningful to wireless LAN architects and implementers, Xirrus commissioned Tolly to develop a cost analysis for three common wireless LAN deployment scenarios: 1) Enterprise, 2) Primary/ Secondary School District, and 3) Convention Center.
This is the main section of a two-part report and contains the summary of the analysis. This report should be used in conjunction with the report appendix (Tolly document 211100APPENDIX) that contains detailed bill of material information.

Motorola WiNG5 Wireless LAN Architecture Advantages:
Lab Evaluation vs. Traditional Hub-and-Spoke WLAN Solutions
Document number:
211114
Release Date:
09 May 2011
Motorola’s WiNG5 architecture was designed to deal with the challenges of higher
bandwidth 802.11n wireless networks and scale efficiently from small to large,
geographically dispersed deployments. In the WiNG5 architecture, the controller
function is distributed throughout the network. In fact, each AP has much of the same
capability as the main system controller.
Because system intelligence exists local to each access point, local WLAN traffic always
stays local - removing a significant burden on WAN resources. Furthermore, in situations
where the APs are unable to communicate with the main system controller, no loss of
function is experienced at the local WLAN and users are not impacted.
Motorola Solutions commissioned Tolly to benchmark the performance and system
behavior of products built on Motorola’s new WiNG5 architecture and compare those
results with solutions from Cisco and another leading vendor2 that are based on
traditional, controller-based architectures. Testing was conducted in April 2011.

Click the link for the 2012 report: Edgewater Wireless EAP3000 Access Point
Multi-Channel vs. Single-Channel Access Point Performance
Edgewater commissioned The Tolly Group to evaluate its EAP3000 multi-channel, wireless chipset’s aggregate 802.11b/g throughput in a reference platform against three commercially available, single-channel enterprise-class 802.11g access points.
Eight different throughput test client mode/association speed combinations were used to verify that performance differences are consistent across an array of connection types. To minimize the impact of RF anomalies and environmental noise, encourage repeatability, and focus on optimal throughput, engineers connected wireless LAN clients to each access point tested over a wired RF link. Attenuation was introduced to some or all of the clients to reflect real-world conditions. Multiple permutations of the tests were run, each having a different set of standard and association rates for the clients.
Results show that the AP based on multi-channel Edgewater technology delivers consistently higher performance than any of the three commercially-available single-channel APs tested.
