This Solution Guide describes best practices for implementing an Aruba 802.11 wireless network that supports thousands of highly mobile devices (HMDs) such as Wi-Fi phones, handheld scanning terminals, voice badges, and computers mounted to vehicles. It describes the design principles particular to keeping devices that are in constant motion connected to the network as well as best practices for configuring Aruba Networks controllers and the mobile devices. The comprehensive guide addresses six areas of network planning to ensure a high quality of service for roaming data and voice sessions: device configuration, airtime optimization, roaming optimization, IP mobility configuration, IP multicast configuration, and interference resistance. A detailed troubleshooting section covers common issues that arise with these types of WLANs.

In centralized Aruba WLAN deployments, the mobility controller is the heart of the network. The controller operates as a stand-alone master, or in a master-local cluster. Aruba provides several redundancy models for deploying mobility controllers. Each of these options, including the choice to forgo redundancy, must be understood so that the correct choice can be made for each deployment model.

For WLANs to be able to reliably support mission-critical, high-throughput, or time-sensitive applications, RF interference must be continuously monitored. The WLAN must automatically and dynamically adapt to mitigate the effects of any interference in the environment. WLAN infrastructure has to provide the administrators with real-time, historical, and proactive visibility into the air to diagnose and mitigate interference. In this application note we will look at some of the tools that Aruba offers as a part of its WLAN solution that enable administrators to ensure reliable, high performing RF.

This document provides an overview and refresher on key concepts in 802.11 wireless networking, including:
- Wireless communications fundamentals like how channels work and the importance of avoiding co-channel interference
- Factors that impact wireless performance like available channels, channel widths, transmit power levels, and signal to noise ratios
- How lower signal to noise ratios can cause clients to downgrade their data rates, impacting overall channel performance
- A brief discussion of access point planning and placement as well as client roaming behaviors
The document provides useful CLI commands for various functions on an Aruba network including:
- Enabling logging to troubleshoot processes like DHCP or user authentication.
- Checking interface, AP, and radio status and statistics.
- Viewing ARM neighbor reports and scan times.
- Examining user authentication details, roles, and dot1x configuration.
- Checking client connection details, data rates, and troubleshooting high retry counts or errors.
This document provides guidance on using the command line interface (CLI) for Aruba Instant. It describes how to enable SSH access to the CLI through the Instant UI. Once connected via SSH, the CLI session starts in privileged mode, where show, clear, ping and other commands are available. Configuration commands require entering configuration mode using the configure terminal command. The CLI supports scripting through various sub-modes to configure interfaces, SSIDs, rules, and security settings. Help is available using the question mark command.

Adaptive Radio Management (ARM) is a technology that dynamically optimizes wireless network settings like channel and transmit power. It works by having access points continuously monitor the RF environment and report back to the controller. The controller then determines the best settings for each AP based on interference and coverage indices. This allows the network to self-optimize and self-heal in response to changes in the RF environment or user traffic patterns in real-time. ARM provides features like band steering, airtime fairness, and co-channel interference mitigation to improve performance and reliability.
Neighbor Wi-Fi networks, RF noise sources, misbehaving clients, indoor and outdoor coverage patterns can all impact mobile device performance on wireless networks. Join us in this session to discuss how you can design for RF coverage and capacity in challenging environments, proactively monitor your wireless LAN and put together a process for troubleshooting those toughest connectivity issues.
