Adaptive Radio Management (ARM)
Wireless networking has the potential to deliver unprecedented mobility benefits provided that Radio Frequency (RF) spectrum is properly managed. Aruba's Adaptive Radio Management (ARM) takes the guesswork out of RF management by using automatic, infrastructure-based controls to maximize client performance and enhance the stability and predictability of the entire Wi-Fi network.
ARM works with all standard clients, across all operating systems, while remaining in compliance with IEEE 802.11 standards.
802.11n Client Throughput Performance
Since enterprises are likely to deploy a variety of class 802.11n Draft 2.0 client types, testing was conducted to reveal performance variances and compatibility among different client types. This paper describes the results of the testing including the performance of different client types as well as the impact of multiple clients in an 802.11n WLAN infrastructure.
Aruba's Mobile Voice Continuity Solution
There is much evidence that Enterprises are ready for a dual-mode Wi-Fi — Cellular mobility solution: this is clear from the technical press, analysts and from Aruba's own customers. This interest has prompted Aruba to look at the state of the art in dual-mode handsets, IP PBXs and the different forms of FMC (fixed-mobile convergence) solution available in the market.
Aruba and Cisco NAC Integration
Cisco NAC is the architecture that provides mechanisms to authenticate and verify the client integrity of a host before it is permitted to enter the network. This extends across various interfaces of network access, including wired, wireless and remote access.
Video Surveillance Solution Over the Aruba Infrastructure
Video surveillance is the term used to describe the use of cameras and video equipment for surveillance and security. This design guide offers recommendations for deploying third- and fourth-generation video surveillance solutions, which are alternatively known as IP surveillance.
Secure and Scalable Enforcement of Microsoft’s Network Access Protection in Mobile Networks
In today’s era of increasing mobile computing, one of the greatest challenges to businesses is the increasing exposure of client devices to malicious software such as viruses, worms, and spyware. No longer are user devices primarily desktop systems that remain behind a corporate firewall and in contact with IT management systems at all times.
Instead, companies increasingly outfit their employees with wireless-equipped laptops, PDAs, and other mobile devices that regularly leave the corporate network and attach to networks at homes, public wireless hotspots, hotels, and partner sites. When these devices return to the corporate network, any malicious software they may be carrying can be spread to other corporate systems. For this reason, ensuring that these devices are properly protected from malicious software has become a key interest of IT departments.
Beyond the Hype: Voice over Wireless LAN
Voice over IP over Wireless LAN (VoWLAN) is becoming increasingly important to enterprises, and network managers are increasingly planning it into their next round of technology upgrades. Many have called voice the “killer app” for wireless networks, and others have called wireless the “killer app” for voice over IP (VoIP).
While VoWLAN is in its early stages, network managers have clearly indicated their desire for wireless LAN systems to support current and future requirements of ths technology.
Aruba Networks supplies customers with the most comprehensive set of VoWLAN features available with industry- leading performance independently verified by leading test labs.
Dedicated Air Monitors? You Decide.
Aruba customers commonly ask:
“Do I need dedicated air monitors in an Aruba deployment, or can I get by with just access points?”
The answer is:
Aruba access points double perfectly well as air monitors, but dedicated air monitors provide extra performance and protection.
Meeting FIPS Requirements for 802.11i WLAN
From the boardroom to the battlefield, no user has a greater need for mobile communications than the Government. Until recently, however, WLAN technology has been a trade off between increased productivity and security. To take advantage of wireless technologies, the only option for government agencies, per Department of Defense Directive (DoDD) 8100.2, was to deploy a Layer 2 encryption overlay on top of their wireless infrastructure.
Aruba Networks took a fundamentally different approach to WLAN security by centralizing the architecture. The result was the Aruba Mobile Edge solution.
