hey,

i recently purchased a 54 mbps wireless PCMCIA card.
The router is on 2.4 Ghz.

Now, is this "bad" for me (physically speaking)
I mean i have a laptop (IBM ThinkPad) and i am (as we speak) having the laptop in my lap and writing this thread.

Okay, my question is, How "bad" is it for me?

And the PCMCIA card has like a 15 meter radius before it cannot find the signal any longer. Whats up with that? It should be able to have a 300 meter radius.

You mean like the EM field?

Harmless. You've been exposed to far worse.

i guess that the Smokedetector is worse then.

and another question, can i become sterile from it?

hmm..I doubt the smoke detector is worse. But either way, it won't make you sterile.

About the pcmcia card-- do you have anything between the laptop and the router?

Firstly if you have your laptop on your lap, I think your major concern should be with it overheating. It's usually advisable to keep laptops on table surfaces and to have the little legs that extrude out in use so that the surface temperature of the laptop (notibly near it's battery) can keep cooler than what it would with the insulation of your legs (or a carpet etc).

It's also suggested that if you have a mains adapter to also put it's powerpack onto a surface similar to the table rather than being sat on a deep-pile carpet etc.

This will hopefully increase the life expectancy of your Laptop. As for actual health-threats from it, Laptops are less hazardous than computers with CRT's.
(CRT's over time start acting up like old TV's, currently when mines turned off it generates such a high level of UV it's almost like watching an Arc welder which of course you should do because it causes retinal damage)

Since the laptop is also designed to use a low voltage thats notibly in regards to it's "mobile" usage it also makes it safer since your less likely to fry yourself with electricity.

As for your PCMCIA card, it could be likely that depending on how much power it draws from the system defines on how strong an output/reach the card has. This means if you are running on batteries, it's more than likely that the system is conforming to power conservation and therefore not using so much power on it's peripherals.

There is of course the added point of is there objects between you and your router, and more notibly because of all the recent publicity of how easy it is to connect to peoples wireless networks (due to some people not understanding how to use MAC addresses of their adapters to lock their routers down to just their systems) it's possible that in the case of Tree's, Trees are absolutlely horrific when it comes to recieving radio signals. I'm not sure how, but the trees themselves act a bit like a Faraday cage does with electricity just with radio signals, they seem to be able to absorb them so well (Far better than Animal lifeforms but then again thats what a tree is suppose to do, take photonic energy and convert it through photosynthesis into energy it can use to create sugars etc. Although thats photons, radiology uses frequencies that aren't as fast but are still frequencies.)

omg, my balls belongs to the wes clan, i fear that you might use them as a weapon to defend your lunarbase. What will i do?
