This wireless was foiled

As a wireless person I receive occasional questions about electromagnetic radiation which I just referred to the Environmental Health and Safety department.  Some pictures below show where someone appears to have taken matters into their own hands, but even without the foil I doubt this person was hitting any exposure limits from the AP https://www.fcc.gov/general/radio-frequency-safety-0

Personally it is a little funny that some people worry about exposure from APs, yet will hold a cell phone right next to their head for an extended period of time.

Super Bowl 50

An interesting thing about where I work is that am within sight of Levi Stadium.    Here is a picture I took from the building a few days before the Super Bowl.

The Goodyear Blimp was already flying around the area.   If you are in the area and have a scanner then there are some frequencies you could try to listen to the blimp http://wiki.radioreference.com/index.php/Blimps

While I do not have any predictions as to which team will win, it is a safe bet that a record amount of  data will be transferred over wireless networks.   http://www.techrepublic.com/article/super-bowl-50-to-showcase-new-tech-shatter-bandwidth-records/

This what I saw at the Phoenix Airport last year.  Talk about close!

  

Radio Shack

If you are also into the RF part of communication make sure to stop by Radio Shack before it is too late.  Closing of the stores represents a change in purchasing options, but in the short run it also means some good prices.  I bought some PL259 connectors for about a dollar each today.

Wireless Networking Videos

If you are working on the CCNA or CCNP wireless or any of an number of other wireless certifications such as http://www.cwnp.com/.  It is useful to know that a set of videos by Jerome Henry were just released by Cisco Press.  (Jerome Henry is a well known person in the wireless world.  He has both a CWNE and a CCIE wireless.)  The videos are called Wi-Fi Configuration, Deployment and Troubleshooting LiveLessons True there is material available for free on YouTube, but the quality varies greatly.  

At this point I am about half way through the videos, and would recommend it as a good use of time for anyone in wireless networking.

A different type of rogue wireless device

If your job involves tracking down rogue wireless devices, make sure to look at the vending machines in the area.  Our fancy new Coke machine turned out to have a wireless connection.  It takes something like this http://www.flukenetworks.com/enterprise-network/network-testing/AirCheck-Wi-Fi-Tester to be sure for a specific case of your site, but as you can see from a this reference http://mandetech.com/2010/12/16/odyssey-software-enabling-coca-cola-freestyle-machines/ that the capability does exist.

Wireless in stadiums and other large venues

With the memory of the Super Bowl fresh, it is natural to think about wireless in a stadium.  The Levi stadium in Santa Clara has a wireless network that is nicely done.  It was done by Aruba networks with APs under the seats to deliberately limit the cell size http://www.mobilesportsreport.com/2014/08/stadium-tech-report-aruba-networks-chief-designer-on-building-the-ultimate-stadium-network-at-levis/   In other cases absorption from bodies is bad, but in this case it is good.   http://www.arubanetworks.com/wp-content/uploads/stadiumRFfund.pdf.  When planning your own implementation make sure to review some of the wireless vendor solutions already out on the web.  For the case of Aruba it may be found at http://www.arubanetworks.com/solutions/lpv/
