Wireless Networking Question

Ok, please excuse my lack of knowledge when it comes to wireless networking, but I have a very basic question that I thought of last night while I was talking with my brother on our cordless 900mhz phone. Heres the question:



Can I get an semi-accurate range idea of how well a wireless 802.11b connection will work by using my 900mhz phone around my house to pinpoint hotspots or weak spots?



Example: If I can use my 900mhz cordless phone in my basement without any loss in clarity, can I assume that a 802.11b wireless connection will act just as well?



Thanks for any feedback.

    No, won't work. The phone is 900Mhz, and the wireless card is 2.4 Ghz. The two frequencies behave differently when passing through walls and such. Your phone also has a more powerful transmitter/antenna. One example would be to put your phone in your microwave (DON'T turn the microwave on) and call your phone from a second line. It should ring. But if you can it your laptop in the microwave (I refer you to my previous warning) It will not receive any signals whatsoever.

    Technically, yes. But they are low-powered microwaves which are harmless.



    The lead and other heavy metals in our drinking water, paint, and gasoline shield us from this specific radiation. To my knowledge there has never been a "Exploding potatoes" situation linked with Airport or any other 802.11b/g device. <img src="graemlins/lol.gif" border="0" alt="[Laughing]" />

    Yea I know I'm just joking around. I was handling some Ir-192 yesterday so I'm off the scale.

    Dr. Bott ExtendAIR Directional or Omnidirectional Antennae are spec'd with Apple part numbers, but no indication of signal boost is present on the tech specs page
