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.

WiFi Pilot Post on CWNP.com

As you can see from the graphic on the left, I have a new blog post available on the CWNP homepage, http://www.cwnp.com 

If you are unfamiliar with the CWNP program, they are a vendor-neutral certification body for wireless networking and security.  

My most recent blog post at CWNP talks about a new product offering from CACE Technologies and MetaGeek, called “WiFi Pilot”.  The WiFi Pilot WLAN Analysis kit contains a WiSpy Spectrum Analyzer, an AirPcap wireless packet capture device, and the WiFi Pilot analysis software.  

Check out the review on CWNP for an extended discussion of product functionality, pricing, etc.  

One other thing that I mention in the post is the Sharkfest Conference for Wireshark Users and Developers.  The conference is being held Jun 15th – 18th.  I am attending the conference and *super* excited about it – feel free to email me at douglashaider <at> hotmail <com> if you are attending. I would love to meet up and chat!

MetaGeek to Offer Upgrade Program for Wi-Spy Devices

MetaGeek, makers of the Wi-Spy Spectrum Analyzer announced earlier this week a special upgrade program.  It allows existing customers to upgrade from Wi-Spy v1 to either a Wi-Spy 2.4X or the newer, dual-band Wi-Spy DBx.   To upgrade, customers pay only the price difference between the devices.

MetaGeek then sends out the new device and a pre-paid FedEx envelope to return your legacy device.  The program was designed this way to allow for no down time in your Layer1 WiFi analysis capability.  However, returns must be sent back to the company within seven days. 

The official announcement states that this is a trial offer, and that the program may not be permanent.  It is also limited to one upgrade per customer.   Additional details, pricing, and ordering information can be found on the company’s official upgrade page.  

The Wi-Spy is definitely one of my favorite troubleshooting and analysis tools, and I think this is a great program.  It actually reminds me of another favorite tool, the AirPcap Wireless Packet Capture Tool, which offers a similar upgrade program by its manufacturer, CACE Technologies.

Adventures in Capturing Wireless Packets

Just a quick FYI for those *true* WiFi packet analysis junkies out there – I installed OmniPeek Professional 5.1.4 on my HP 6910 laptop.  The software “works” with embedded Intel wireless NIC, but reports invalid data rates for 802.11n traffic.

The work around that I came too was to purchase a 3rd party, dual-band 802.11n USB adapter that has a supported API within the OmniPeek software.

I also have an AirPcap Nx device from CACE Technologies that I like *very* much – USB form factor that allows for wireless packet capture in Windows.  AirPcap integrates directly into Wireshark, which is nice since I “grew up” taking wireless captures in Lib PCAP format under Linux and looking at them in Ethereal.
