Rapid, location-aware troubleshooting with Aruba Central and Aruba UXI agent for Zebra

By Abhinav Raj, Product Marketing Manager

When you need to troubleshoot and fix a network issue, you need the accurate location of the issue, and a tool to analyze and fix the issue.

Consider a warehouse scenario where employees are constantly moving with handheld devices. These devices are Wi-Fi-connected and help employees perform a range of tasks including inventory planning, management, and storing. A drop in network performance in one area of the warehouse can create a series of sequential critical tasks, requiring IT teams to be vigilant and continuously monitor network health to stay ahead of outages. When a network issue does happen, it needs to be fixed asap so it does not affect business outcomes. In order to make this happen, IT teams need the accurate location and the appropriate tool to fix the issue.

Aruba recently launched the UXI agent for Zebra, which runs passively in the background on Zebra devices and constantly monitors network performance from the Zebra client perspective, providing precise insight into how Zebra devices are experiencing the network. The UXI agent also measures SIP call quality and roaming performance when Zebra devices are carried from one area in a facility to another. Most importantly, it provides the location of the issue on the floor map from Aruba Central, pointing out the problematic AP and details of the issue. This is enabled by having the floor map of the facility in Aruba Central, and using 802.11mc to identify the issue location.

Aruba Central is an AI-powered network management solution that helps IT teams to remotely manage, fix and improve the network performance, and when used with Aruba UXI agent for Zebra, the complete solution provides an end-to-end view of network health – from network side and from an end user’s perspective. UXI agent for Zebra continuously monitors network performance from Zebra device perspective and provides the issue location, along with highlighting what went wrong, and Aruba Central provides the tools using which the network issues can be fixed – remotely and rapidly.
