Wi-Fi with dish and cantenna


The photos shown here document our installation, made in October and November 2003, of a wi-fe network between two house about 300 meters farm with some trees in the middle. We managed to reach, with two D-Link DWL-2000AP access points, an average spped of 17 Mbps, which actually seems the maximum achievable with those models. Without the dish, that is to say only by using two cantennas, we reached 15 Mbps spped.

We are me, my brother Alessandro and our friend Gliano.

Ale on the roof Alessandro on the top of the roof beside the dish used on one of the sides of the wi-fi bridge. It's a nice
1 meter and 80 centimeters disc, made by Fraccaro, which was in
the past used for satellite TV. You can see Friuli mountains on
the background.
Cantenna and dish detail Detail of the cantenna which serves as illuminator for the dish. The access point is contained into
the rectangular metallic box.
Cantenna and cables detail Detail of the cantenna, from the bottom. You can see the two cambles (power and ethernet network) which
descend; also, you can see the cable which connect the access
point with the cantenna.
The second cantenna The cantenna on the other side of the wireless bridge, in Gliano's garden.
The second cantenna 2 The same devilish instrument, seen from the front.
Full view of the second cantenna View of the entire structure on the "cantenna side" of the bridge.
Trees The trees located between the two points of the bridge. It's about 200 meters far from the side in which the
dish is installed, and 100 from the other.
