This VRD covers the deployment of Aruba WLAN in a typical campus network, and it is considered part of the Base Designs within the VRD core technologies series. This guide covers the design recommendations for a campus deployment and it explains the various configurations needed to implement the Aruba secure, highperformance, multimedia grade WLAN solution in large campuses.
Aruba WLAN has a logical four-tier operating model that consists of these four layers:
Management - The management layer consists of AirWave®. AirWave provides a single point of management for the WLAN, including reporting, heat maps, centralized configuration, and troubleshooting.
Network services - The network services layer consists of master mobility controllers and Amigopod. Amigopod provides secure and flexible visitor management services. The master controllers provide a control plane for the Aruba WLAN that spans the physical geography of the wired network. The control plane does not directly deal with user traffic or access points (APs). Instead the control plane provides services such as whitelist coordination, valid AP lists, Control Plane Security (CPSec) certificates, Radio Frequency Protect (RFProtect™) coordination, and Remote Authentication Dial-In User Service (RADIUS) or authentication, authorization, and accounting (AAA) proxy.
Aggregation - The aggregation layer is the interconnect point where the AP, air monitor (AM), and spectrum monitor (SM) traffic aggregates. This layer provides a logical point for enforcement of roles and policies on centralized traffic that enters or exits the enterprise LAN.
Network access - The network access layer is comprised of APs, AMs, and SMs that work together with the aggregation layer controllers to overlay the Aruba WLAN.

Hi Jamie, A great VRD that covers the deployment of Aruba WLAN in a typical campus...
A great VRD that covers the deployment of Aruba WLAN in a typical campus network.
I have 2 comments regarding ''Type of Wired Access Switches":
- For 802.3af switches when using AP33x, both 5Ghz and 2.4Ghz will operate 1x1:1 mode not only 2.4Ghz radio.
- Why IPM (Intelligent Power Monitoring/Management) is not considered as part of the design? it will help using AP33x with no restrictions when plugged to a 802.3af switch.
This guide explains how to implement an Aruba 802.11n wireless network that must provide high-speed access to an auditorium-style room with 500 or more seats. Aruba Networks refers to such networks as high-density wireless LANs (HD WLANs). Lecture halls, hotel ballrooms, and convention centers are common examples of spaces with this requirement. Because the number of concurrent users on an AP is limited, to serve such a large number of devices requires access point (AP) densities well in excess of the usual AP per 2,500 – 5,000 ft2 (225 – 450 m2). Such coverage areas therefore have many special technical design challenges. This validated reference design provides the design principles, capacity planning methods, and physical installation knowledge needed to successfully deploy HD WLANs.
The solution would be to place it right on the website along with all the other Aruba VRDs....

...went All wireless office with Micorosoft Lync. We learnt a lot from your environment. Anytime...
Thanks, Jay (thecompnerd)! Always a pleasure to work with you. You are one of our few customers who went All wireless office with Micorosoft Lync. We learnt a lot from your environment. Anytime, please give me a shout if you need any help with anything.
.... Thank you again, Julia Ostrowski Aruba Networks | Customer Advocacy
Hi there--so glad this doc is helpful to you! We love getting feedback from our customers.
We are working on a solution that would allow you to directly download these docs as PDFs--in the meantime we hope there is not much of a delay for you to access the information as a PDF.
Thank you again,

This guide presents a new wireless architecture to deliver a multimedia-grade experience to students living in residence halls. We will show that large numbers of low-power microcells located directly in the student rooms is the only effective solution to fully meet user expectations. We provide simple rules to determine the density of these microcells for different types of construction. We also provide migration options to enable many institutions to deploy this architecture without pulling additional cabling.
...you please point me to any reading to understand? Thanks!!! [EDITED] An Aruba engineer...
Thanks for your writing, very useful. I have a question on Mcast. On page 9 you recomend to enable both MCAST Rate Optimization and DMO, but also rise DMO threshold to 80. How can be preferable to use 80 TXOPs instead of broadcasting the MCAST frame at the optimized rate? Could you please point me to any reading to understand? Thanks!!!
[EDITED] An Aruba engineer kindly helped with this basic question. Mcast frames do not use MCS datarates and contains a single packet per PDU. DMO uses MCS datarates and many packets can be aggregated.
This guide covers Aruba Mobility Controllers and is considered part of the foundation guides within the VRD core technologies series. This guide will help you understand the capabilities and options you have when deploying an Aruba Mobility Controller. This guide describes operating modes for the mobility controller, licensing, forwarding modes, logical and physical deployment, redundancy, and how to select the appropriate mobility controller based on scalability requirements. Version 9 includes information on the 7200 series controller.
