Hi there - Anyone know of any commerciallly available device/tool/accessory
that will enable enhancement of wireless signal reception by a laptop with a
built in wireless card....?

Cheers,

Dave




Re: enhancing sensitivity of a wireless card in a laptop


Some PCMCIA card can be connected to a better external antenna, but not many
and I cant ever recall hearing of a built in chip with an external antenna
connector, but that would be cool, and some have the capability to have
thier transmitter power tweaked via the manufacturers included utility, but
does yours? I Have no idea......

Re: enhancing sensitivity of a wireless card in a laptop


I made such a clip, it works, fits most of the cards and is
especially nice in connecting laptop to directionl antenna.

I wrote disclosure document with US Patent office thinking to sell the idea
to someone - never got to do it ...

Another Access Point, which can be configured as a "repeater".

An example:  I want to use my laptop in the building across the
street.  Unfortunately on the first floor of that building the
signal strength is typically about -83 dBm at best, and depending
on obstructions (literally on where cars are parked between the
two buildings!), might be more like -95 dBm.  Well, -83 dBm isn't
very good, and -95 dBm essentially isn't there.

So I put a repeater on the second floor of that building.
That's not where I want use the laptop, but that is where the
signal strength is good.  The repeater gets a signal more like
-70 dBm now, and so does the laptop.

Well, I did not think he was asking for a thirdpart hardware solution, but
yep, an AP or repeater will do it.

It's called a "device"!  As in "any commercially available
*device*/tool/accessory".

Of course another hardware solution might be approprite use
of a high gain antenna, and maybe even a dedicated AP with a
high gain antenna.  What might work depends on details not
provided.
