Effective Range ?

What's the effective range of an 802.11B signal, presuming no walls to
block it?

Indoors : signal travel as far as 150 meters
Outdoors: signal range is over 3 times greater i.e. 500 meters

There isn't a simple answer as a variety of factors have to be taken
into account.
1.Tx output power.Different countries have different rules for max power
output and it can vary with the type of operation, point to point for
example.
2,Rx sensitivity.Better sensitivity will increase range.
3.Type of Antenna on both systems can have an impact on range.Height of
the antennas can also have an impact.Line of sight and multipath signals
can also impact.
4,Data transfer rate.the slower the speed the more reliable the data and
hence a longer distance can be used.
etc......

People have achieved distances of several km's using the correct
combination .

If you believe the advertising schpiel.

Reality check: expect to get no more than 100ft unless you use proper
antennae, and expect to get much less if you have tinted glass, trees
or anything cute in the way.

This is interesting because over the past couple years there's been
talk about an 802.11n wireless standard. I read an article the other
day about how it's fianlly been approved by the IEEE and can extend the
signal range by 50%, compared to 802.11g. And, it's four times faster
too. Here's the link:

Please re-read the very first line again:
"A faster and more far-reaching wireless Internet is coming
within a year..."
It hasn't been approved yet and is not expected to be approved for
quite some time. See:
http://grouper.ieee.org/groups/802/1..._Timelines.htm
for the timeline. Looks like 802.11n is scheduled for approval in
July 2007.

Incidentally, MIT Technology Review is one magazine that's well worth
reading.
