CWAP Beta Course – Day 2

Today was the 2nd day in the CWAP (Certified Wireless Analysis Professional) beta course.  Today’s material was a lot more hand-on / lab type exercise in capturing and analyzing traffic.  From what I could tell, there were three main tools used by the course attendees:

They all seem to have their pros and cons, and they all seem to cost about the same amount of money (especially if you want to do multichannel packet capture on ~3 channels).  Which tool do you prefer?  Why?

The course contains an enormous amount of detail, such as the exact length (in microseconds) for slot times for each PHY type as well as a discussion on the application of that detail (i.e. how do the different slot times affect WLAN performance with and without QoS enabled).

Again, I thought one of the most valuable things were the networking opportunities with the other attendees and the sidebar conversations.  A colleague (and good friend) of mine, Ken Hall, was even inspired to sign up for a Twitter account (@wifiscubaguy) to continue the interaction outside of this course / classroom.  His account will definitely be on my next list of #WirelessWednesday mentions.

Tomorrow is the last day of the course.  From what I know, we are covering a lot of 802.11n concepts, as well as spectrum analysis, which should be a blast.

Packet Analysis 2.0

It seems like I am going to bring my wireless packet analysis to a whole other level – “Packet Analysis 2.0”, if you will. Two of my favorite wireless capture and analysis tools have recently been updated – OmniPeek Professional and Wireshark.

I have been at meetings at our company HQ (Xirrus) most of this week, so I haven’t had a lot of hands-on time with either updated tool.

OmniPeek Professional has just been updated to version 6.0.1, as of April 3rd. It seems to offer much more flexibility of viewing multiple data windows through mechanisms similar to tabbed browsing.

I also downloaded a few plug-ins for OmniPeek Professional, including the multichannel aggregator – once I acquire one more USB 802.11n dual-band adapters, I will try to write a blog post documenting my experiences with the aggregation feature.

The new version of Wireshark seems to focus on a lot of bug fixes, although it includes an experimental package for Mac OS X 10.5.5 and above. Version 1.0.7 of Wireshark was announced April 8th. On the Wireshark front, I am attending Sharkfest this June, which I am pretty excited about.

Now that I am thinking about wireless product upgrades, I realized that AirMagnet also came out with an updated version to their Site Surveyor product about six weeks ago (version 6.1_13206)

So many product updates, so little time…
