Wi-Fi Ranges

So, I was at the local sandwich shop last night, and I noticed I was able to
pick up a signal from a local T-Mobile hotspot, which I have an account
with. It was only one bar out of five. But I was able to connect to it and
surf the web without any problems.

I then looked up the hotspots in the area, and I saw that the closest one
was a Fed-Ex/Kinkos about 2-3 blocks away. Measuring it on the map, I
estimate it to be at least 800 feet from where I was.

Is that normal for wi-fi routers to have such a large range? That seems a
bit far to be picking up a wi-fi signal. The router was a little uphill from
me, though not a very steep hill.

Thanks,

Neil

For those type of deployments, they set it up it work within the
building. So it will likely get out into the parking lot also.
That's all the need to care about.

Will it go farther? Sure. Will it be a reliable link? Most likely
not. I installed a Linksys WRT54G and it was usable over a thousand
feet away which surprised me.

A true case of "You mileage, err...footage may very".

commercial grade access points may have higher gain antennae than
are normally found in home/residential equipment.

Doing testing with a couple of Cisco APs and high gain omnidirectional
aerials we've had them working over several hundred meters , and even
further with directional ones but that's on open ground. In a built up
environment it's unusal to get anywhere near that.

It's possible there was another hot spot not shown on your map

No, the chances of there being another hotspot are very slim, as there's
only a few types of business that have T-Mobile (Starbucks, Kinkos, some
hotels and airports -- that's about it). This wasn't a random hotspot. It
was a T-Mobile hotspot, and there are only a discreet set of them.

As for open ground, though, the place where I was down the street (to the
south) and a little west of where the hotspot was. In between (the northwest
corner of the intersection where I was at) was open. Thus, between me and
the hotspot, there were no buildings. I'm sure that was it.

Please do not top-post. Your answer belongs after (or intermixed
with) the quoted material to which you reply, after snipping all
irrelevant material. I fixed this one. See the following links:

The world record for unamplified WiFi using off-the-shelf Linksys APs and
very large omnidirectional antennas is, I believe, over 280 kms.

The record using a home made directional antenna at a hackers convention
in Las Vegas a couple of years ago was 51 miles. Although I never
learned if they were on top of a mountain or not. I bet they were.
