RE: Real world 802.11x distances

["Ian Lowe" <ian.lowe@xxxxxxxxxxxxxxxxxx>]

g has a much larger range normally - using a Belkin "b" AP, I can
get a
signal on my driveway just outside the house. Using a Vigor 2600VGi, I
get a nice solid signal across the street - a good 20 metres away.

Could be down to device/manufacturer variations, but we see this most of
the time with Netgear and Linksys "g" kit too.

That being said, it's our experience that a concrete floor is pretty
much death for any wireless network, b or g. I think it's the rebar, to
be honest, but in several of the buildings we work in we have had to
drill a hole for CAT5, reseal it with intumescent material and use two
access points.

As always, YMMV.

I'm trying to ascertain what real world experiences people have of
802.11x wireless reception and distances.

I'm currently a b users and find a couple of stud walls and a breeze
wall are enough to almost kill a wireless signal.

i've been told that g goes further ? - is this correct ?

I've been having sneek peaks at a broadband enabled alarm panel -
inbuilt webserver, 802.11g camera ready - event recording, X10 interface
etc. etc. - looks very interesting and could be a great move forward in
the security world.  My real concern is the distance g will work at in a
real world environment.

We do a lot of houses with concrete mid floors, and i've been pretty
convinced that wireless will not penetrate these.

Does anyone have experience of going through concrete floors ? and if so
how successful is it.





Dean.
