On my network, the most common 802.11 client is 802.11g, almost 50% of the clients on my wireless network are 802.11g. Here are the distributions the type of clients:

802.11a – 19%
802.11b – 14%
802.11g – 50%
802.11n 2.4G – 13%
802.11n 5G – 5%

Does your network looks similar?

Just received a couple of new Cisco 1142 Lightweight AP(data sheet).

Here are some pictures:

It is a much better AP compare to 1250 for indoor carpeted office environment for the following reasons:

1. It uses less power (12.95W vs 18.5W)
2. It is lighter, and smaller (2.5lbs vs 5.1lbs)
3. It has built-in antennas (you can get 5GHz, or dual-band 5GHz and 2.4GHz)
4. it is prettier
5. It has more memory (128MB vs 64MB on AP1250)

The PCI DSS Wireless Special Interest Group has released an Information Supplement in July 2009 for DSS 1.2. It clarifies some of the vague areas in PCI DSS wireless requirements.

The most obvious requirement that stands out is the requirement of rogue AP detection. In the past, enterprises the do not have wireless network implemented would just tell the auditor that they do not have any wireless networks and thus none of the wireless network requirements would apply to the merchant/service provider.

Well, with this new Information Supplement, the enterprises will be required to run Wireless IDS or IPS, or Wireless Analyzer atlease quarterly to look for rogue AP on their network, even if the enterprise does not run a wireless network.

I can see that this requirement will open the door that were previously closed for many wireless vendors/consultants/channel partners to sell wireless security to the enterprises/SMB.
