“Eye P.A. will summarize what is going on in a very flexible, graphically-rich style. With a few clicks, you can filter exactly what you are interested in and get incredible insights in to what is going on over the air.”
— Nigel Bowden, Mobility Consultant at Bowden Networks Ltd
After you’ve ruled out interference, your users may still be experiencing issues. MetaGeek’s Eye P.A. packet visualization software shows you how your channel is being used, packet-by-packet. With just a glance, you can get an idea for the total utilization of air time, packets sent, and bytes present in your capture– the bigger the slice, the more activity taking place.
From here, it’s easy to drill down to exactly what you’re looking for, so you can find and fix packet issues and improve overall network capacity.
“I recently had a manager with a new Dell laptop that was horribly erratic on our usually-reliable 802.1X based WLAN. The curious thing was that another co-worker had the same model, and had zero problems. Using Eye P.A., I was able to quickly find both devices in the treepie, drill in for differences, and see that the problem machine was pretty much an exercise in re-transmissions. A quick driver update did the trick.”

A lot goes into deploying a wireless network, and sometimes settings get overlooked. The Analyze Tab will alert you to a number of potential issues, along with suggested solutions that can help you to increase your network performance.
Eye P.A. makes it easy to identify slow conversations that could be causing network slowness or inefficiencies. These could be legacy devices on your network, or maybe a certain device that is taking up more than its fair share of airtime. By looking at clients from the packet level, you can see which devices are transmitting, how much airtime they’re taking up, and how fast they’re talking.
The best thing about Eye P.A. is its intuitive, visual take on filtering with its multi-layered pie chart (“treepie”) system. With just a few clicks, you can drill down into the exact network conversation that’s causing the problem, without scrolling through hundreds of rows of data in a huge table.
Eye P.A. color-codes subframe types as well, so you can quickly see how much traffic was management overhead (purple and orange), and how much traffic was data payload (blue).
If you use Wireshark to look at packet contents, you can harness Eye P.A.’s powerful filtering capabilities to do the heavy lifting for you, then export only the most important data to Wireshark for row-by-row analysis.
Eye P.A. visualizes 802.11 captures from a variety of sources, and supports the following file types:
“I can now get a big picture view of PCAP files in seconds without needing to spend a lot of time decoding things.”

In addition to supporting a variety of packet capture formats, Eye P.A. also supports packet capture with the AirPcap Nx. This 2×2 MIMO device allows you to record 802.11a/b/g/n packet captures in both the 2.4 GHz and 5 GHz bands, and support for AirPcap Nx is built into Eye P.A., so you won’t have to launch another program.
