Eye P.A. is a wireless packet analysis tool that visually displays all of the conversations on a Wi-Fi channel. The software is capable of tracking client devices by MAC address to troubleshoot speed and connectivity issues on a wireless network. More importantly, Eye P.A. will show you which competing networks and Wi-Fi devices are causing headaches for your users. This type of examination shows you the congestion caused by the neighbouring networks that share your channel.
Using multi-layered pie charts called “treepies” Eye P.A visualises the top talkers and the amount of Airtime, Bytes, and Packets used. The software’s built-in analysis engine will notify you if your network is using a non-standard channel, legacy data rates & devices, and the presence of protection mechanisms – all of which are common culprits in reduced network performance. Eye P.A. is an indispensable tool for Wi-Fi engineers and troubleshooters.
Filters and Treepies
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)

Fix Network Misconfigurations
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. will alert you if it discovers high retransmit rates, legacy data rates, and other problematic network settings.
Find Top Talkers and Slow Conversations
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.
Export To Wireshark
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.
Supported File Types
Eye P.A. visualizes 802.11 captures from a variety of sources, and supports the following file types:
During this snapshot, the “Bronco-Wireless” ESSID had a retry rate of 58%, which gives us a good clue that devices are repeating themselves too often.
Capture 802.11 a/b/g/n Packets with AirPcap Nx
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.
