Aruba's 802.11n Secure Mobility Solution

Mobile users need and expect the same secure, reliable access to company networks, servers, and applications when they're connected wirelessly as they do when sitting at a desk plugged into a wired network. Aruba's secure mobility solution delivers performance comparable to wired LANs at a fraction of the cost, letting you right-size the access layer of the network while untethering users and simultaneously improving network security.

The IEEE 802.11n standard forms the basis of this solution. Thanks to 802.11n, wireless networks are finally able to satisfy the performance requirements to be a user's primary - or even exclusive - connection to the enterprise network. But 802.11n alone is only one piece of the puzzle. Only Aruba can fill in the rest of the pieces, with technologies such as Adaptive Radio Management to increase the reliability of the wireless network, identity-based security to protect enterprise assets, and application-aware QoS to ensure all enterprise applications, including voice, function properly.

To simplify deployment, the solution is designed to leverage existing edge and core infrastructure - including power-over-Ethernet (PoE), cabling, switches, and routers. For example, Aruba's new 802.11n Access Points can be powered using existing 802.3af PoE, minimizing the need for an upgrade just to support 802.11n. 802.11a/b/g access points are also available that can be software-upgraded to support 802.11n in the future. This design allows customers to follow an IT migration path in line with their preferred schedule and available budget.

Aruba 6000 Controller

The heart of Aruba's secure mobility solution is the controller. Aruba's 6000 controllers can be used with new, or retrofitted to existing, Aruba 6000 controller chassis, and includes the following features:

• 32-core, multi-threaded network processo
• Dynamic reallocation of processing cores based on service profile
• Dedicated cryptographic processor cores
• High performance hardware acceleration engine is field reprogrammable via software updates

With a full complement of four hot-swappable modules, an Aruba 6000 Controller has the following specifications:

• 80Gbps throughput
• 32,768 users
• 2048 local access points
• 8,192 remote access points

Remote access points are ideal for telecommuter and business-continuity applications as they offer a simple means of securely connecting remote users and sites without having to manage clients.

Aruba 3000 Series Controllers

To serve the needs of small to medium sized enterprises, Aruba offers the new Aruba 3000 Multi-Service Controller family. These three controllers provide up to 8Gbps of throughput and support up to 2048 users, 128 LAN-connected access points, and 512 remote access points. The wireline capability of the new controllers extends Aruba's identity-based security technology to wired networks, eliminating the need for extra-cost security processors.

802.11n Access Points

Aruba's AP-120 family of 802.11n Access Points is based on 2nd generation RF chips and high performance MIPS CPUs with hardware-accelerated cryptographic processing. Featuring a field-upgradeable design and 3x3 Multiple-In Multiple-Out (MIMO) operation, the access points can be used for wireless access, intrusion detection monitoring, traffic analysis, secure enterprise mesh, or remote access point applications. The mode of operation is determined by network-downloadable software, a feature that allows the access points to be re-purposed and updated without the expense of physically accessing the device.

To protect access points installed in unsecured areas, or during use in distributed encryption modes of operation, security credentials can be stored in a Trusted Platform Module (TPM) microcontroller. The TPM specification was defined by the TPM subgroup of the Trusted Computing Group (TCG) for the secure generation and storage of cryptographic keys, and is widely implemented on devices for which high security is paramount.

The access points include automatic Power-over-Ethernet (PoE) management that supports 802.3af, 802.3at, and PoE +, minimizing the need to change PoE infrastructure just to support 802.11n.

The All-Wireless Workplace Is Now Open For Business

Used together, Aruba's new ultra high-performance Multi-Service Controllers and 802.11n Access Points are designed to offer the speed of a wired network, the low total cost of ownership and adaptability of a wireless network, and the security and centralized management for which Aruba is already well known. When combined with an Aruba remote access and/or enterprise Fixed-Mobile Convergence voice solution, these benefits extend across geographic boundaries and provide an extensible platform on which new applications can be built in the future.
