Bomb proof walls. Not a joke!

Having (with a great deal of help), worked out what my configuration
should be, I now could use some advice from anyone who has experience
(or knowledge) of this situation.

In Israel, which is where I find myself, all buildings, (and the one
I'm living in is included in this) are required to have a "safe room".

This room must be gas proof, and withstand something just short of a
nuclear explosion. I can vouch for its construction, because putting up
shelves in it nearly killed me! I went through more drill bits in a
day, than I have done in my previous life, and I'm no youngster!

But, undeterred, my computer is nearly set up in here. All that's
missing is an internet connection, via my hosts cable modem.

So, I go out shopping to buy a suitable wireless router, only to
discover that I'm being warned off doing this, as the walls in these
safe rooms are not only bomb proof, but apparently resistant to
wireless networks as well.

Wires are even more out of the question. The room is truly sealed. You
can't even run a flat cable under the door. Rubber seals all round.

Does anyone have any experience of this situation? Even in another
country? Was I being warned off unnecessarily? Can wireless networks
get through this kind of construction? Is a booster or other form of
amplifier necessary, or useless? Or is the whole issue superfluous, and
its not really a problem at all.

Thanks in advance to all who reply.

I'm just guessing that this room has electrical power; how does that
get in there?

The room does have electrical power (just as well really, as my
computer is hooked up to it!) but the only sockets I can find are
buried in the walls. These rooms are part of the original design of the
building. I don't want to think about what will happen when the place
needs a re-wire!

Put simply, there are no conduits, or ducts. Also, drilling through the
wall, (were such a thing possible) would violate the rooms integrity,
no matter what sealant were used.

If so, you may be able to use Powerline Networking.

I was in the IDF for a while in the early 1970's. Everything is made
of poured concrete and reinforced with politics.

John mentioned power line networking. Methinks this is probably the
best approach. See:

I'm not thrilled with these, but they'll probably work.

Do the rooftops still have 30 TV antennas (and solar water heaters) on
them? If the residents have gone to DBS satellite TV, then there
should be plenty of coax cables and twinleads running into the
apartments. These can be used for ethernet.

Also, if the room has a phone line, there's also phone line
networking:

It's not as fast as the others but good enough.

Well, that can't be true, but it may be the rule. It might be
_difficult_ to drill a 1/4" hole for a CAT5 cable, but it wouldn't
destroy the room's integrity, and some silicone seal would work just
fine against gas ingress.

Unless the door is made of wood or plastic, you are pretty much left
with John and Jeff's suggestions of powerline or phoneline networking.

So use a power-line carrier based system. Netgear and Linksys sell kits.
