    Hiya.Im a 35 year old man who is currently about to study the CWNA WIRELESS CERTIFICATION.
    Im doing this on a low budget, and self study is the only option.

    Could you please reccomend a strategy

    From your recent post on WWDC and the WiFi issues that Jobs had, I don’t follow the statements:

    “The Wi-Fi radio in the iPhone (3G, 3GS, and 4G) is only capable of operating in the 2.4 GHz spectrum, so Apple would want to encourage as many users to utilize the 5 GHz spectrum as possible.

    How should they encourage users to utilize the 5 GHz spectrum? It sounds obvious, but provide plenty of 5 GHz access points. The clients (laptops, phones, tablets, etc.) make the decision of which AP they want to connect to. They make this decision on a number of factors to include signal strength and signal quality. If you provide a relatively high number of 5 GHz APs, clients will migrate to them.”

    If, as you indicate, the iPhone only works in the 2.4Ghz range, how could Apple encourage users to use the 5Ghz range? The same question would be for any OTHER user that uses B/G. Does N operate in the 5Ghz? Maybe I don’t know enough about the operating range of N. Also, as with 802.11a, it operates in the 5Ghz range but has much less penetration ability and, in turn, requires additional access points.

    Do you have any sort of whitepaper that talks about how to set up multiple access points for seemless movement / transition between then in a larger, in-door environment?

    Would appreciate anything you might have on this.

    Hi Douglas,

    I’m the assistant community editor over at ITKnowledgeExchange, and I found your blog through your Twitter link. This month we’re covering all things on wireless networking, and I was wondering if you’d be interested in writing a guest blog post for us. We’d love to have you! If you’re interested or have any questions, please email me at Melanie [at] ITKnowledgeExchange [dot] com.

    I look forward to hearing from you!

    hi Douglas.

    I’m developing a system of indoor position use wifi. however I am having problems with relation to this library of apple. was once private.

    where I use the code.

    libHandle = dlopen(”/System/Library/SystemConfiguration/IPConfiguration.bundle/IPConfiguration”, RTLD_LAZY);

    apple80211Open = dlsym(libHandle, “Apple80211Open”);
    apple80211Bind = dlsym(libHandle, “Apple80211BindToInterface”);
    apple80211Close = dlsym(libHandle, “Apple80211Close”);
    apple80211Scan = dlsym(libHandle, “Apple80211Scan”);
    apple80211Bind(airportHandle, @”en0″);
    this is code work in IOS6 – in root /Application

    to scan the antenna next to the device in case an Iphone. and thus measure the distance in relation antennas.

    put the apple blocked access to this library. I wonder if there is any other option for this development. a new library. that perform the same functions.

    do not intend to jailbreak the app works perfect when installed in the root folder of the device.

    however intend to publish the source code to the community. and even launch a test app in apple store.

    thanks for the help.

    I am a long time Dell customer, who has had just about one of every vrseion of the Dell Latitude in since the C series. Because of pricing differences, I decided to give HP a try with the HP 8560P and am very impressed with it. The design is well thought out, the build quality is first class, and the performance is unbeatable.I can’t think of a single thing that I don’t like about this machine, except for possibly its weight and the fact that HP hasn’t refreshed their docking stations to match the performance of the laptop. Even the best docking station they have available for this laptop has no modem pass-through, only 2 digital video ports at a time, and USB 2.0 instead of 3.0.The keyboard on this laptop has a unique design that works and feels great. Its design prevents spills or dirt from getting into the machine.The new touch-pad is gigantic and works great. There is an eraser head mouse in the center of the keyboard for people who prefer to keep their fingers on the keys. Both can be deactivated in the software if you prefer for them to be off while you use your external mouse.The screen and audio is wonderful.The hing is solid and firm. Much better than on the Dell’s.The performance of this machine is incredible. I rendered a video in Premiere, while running a various scan, copying a DVD, and playing HD contact from Netflix all at the same time. Incredible.For the price, this is the best machine on the market. I highly recommend it, or a custom build vrseion of it direct from HP.
