Possible to extend my wireless network to about 1/2 to 3/4 of a mile.

I saw a post like this where someone wanted to go 2 to 3 kilometers. A
little farther than I need.
The response was that it was probably possible with special equipment, but
is illegal.

Can I do this (legally or not, just want to know my options)? I'm not going
quite as far as the
other poster, so I hope this helps.

I can mount my wireless router in an upstairs bedroom. The other location
is not line of sight as
there are some houses and trees intervening them, but no hills to speak of.

I'm wondering about equipment, will I need to mount special attennas on both
ends, etc.
Leo.

A simple reflector of aluminium kitchen foil around a curved
thin walled plastic container, using elastic bands to hold
the foil in place, can add around 10 percent to signal strength,
about 20 percent to signal quality and around 30 percent
to range.
USB wireless adapters are the most flexible since positioning
is important and the thin USB cable makes this easier.
Increasing the transmitted power by modifying the transmitter
is probably illegal, making most use of the permitted power
is probably ok.
Using a reflector aids signal strength both transmitted and received,
it also cuts out interference coming from the
sides making it more line of sight.
Intervening buildings will probably defeat you.
The USB method is cheap to implement, and you can put one
on a laptop and go roaming to map signal strength, and use
Netstumbler to see what signals are around you.
There are high gain aerials advertised, at a price,
and no guarantee that they will work in your situation.

No you must have line of site, rain/snow and trees will all prevent this. If
you can't see the target it would not work at this distance.

Hi

It is illegal if you use Transmitters that exceed the Output rating of the
FCC.

However, people do achieve such range with legal equipment.

It involves building towers that are high enough to make sure that you can
compensate for the Fresnel effect, and using very hi gain highly directional
Antenna.

The Antennae has to be set with land survey equipment to make sure that they
are looking “eye to eye” since to cannot align them visually from such a
distance.
