Wifi RF exposure

If my Linksys WAP is not needed, I can telnet to it, and type: /usr/sbin/wl down and to switch it on again: /usr/sbin/wl up

But of course only because I modified the soft and added a telnet client. Usually it is off.

Yeah - sounds like a good idea.

It's probably safe to keep the configuration you have. Actually, tinfoil makes a quite comfortable cap, and who's going to see you anyway? ;-)

As for a market for felt liners, just get a bolt or so of felt, make some hat liners, and see what the traffic will bear. ;-) People will buy almost _anything_ off ebay. ;-D

Maybe. Some router functions (like NAT, and MAC tables for switching functions) are learn-as-you-go, so the newly powered router will be inefficient for a few minutes before it 'catches' the data it needs. Your wired router (I presume that's what "simple router" means) will have to substitute for the other-than-wireless-specific functions of the wireless one.

More to the point, WiFi is typically very low power (0.03 watt), and doesn't operate 24/7, just has a low duty cycle with the transmitter usually OFF. Some wireless routers (the Apple Airport ones) have additional control in software, you can lower the transmit power. The numbers DO matter, and by present standards a WiFi transmitter is considered safe, so I believe it IS safe.

Data can make me believe otherwise, mere suggestion cannot.

On most WiFi routers you can turn off the radio. I know that's true of Linksys and Netgear products.

Maybe there is. At least we already have highly sophisticated scientific tests of the various styles:

Well, put the hat on the wireless router then. :)

Seriously, you are in NO danger from the RF emissions. The levels are not nearly strong enough to be harmful.

If you look around the room, you will no doubt find even stronger sources of non-ionizing radiation.

Or more crudely, just unscrew the antenna and remove it.

At least, nowhere near as strong as holding a mobile phone to your head.

I'm thinking of moving to a dark part of the universe where the radiation density is lower.

You're going to shack up with DimBulb?

I wonder. It'd still radiate out the connector and the lack of a load might cause some SWR problems.

Disconnecting the antenna will cause most of the power entering the connector to be reflected back into the transmitter. Some of it is dissipated in the transmitter and cable losses and part is reflected back towards the connector and so on, so only a small part of the original power is actually radiated from the connector.

Unscrewing the antenna on any larger transmitter may damage the transmitter, unless some SWR protection is used, which shutdowns the transmitter or at least drops the output power, if there is a severe mismatch, thus reducing even further the power radiated from the connector into free air.

So, solution: Replace antenna by dummy load. You can make one yourself with a suitable connector and resistor.

That is where the Borg lives, you will be assimilated, resistance is futile.

I resistance is futile, try capacitance or inductance.

Ha! Why go through all the trouble.?

Just book a trip to Washington and hang out with Congress for a while. Even brainwave monitors have a hard time detecting energy there...!!
