Wireless: in africa they can build their own atennas!

With this project, we will learn how to build wireless network with a cheap and good technology and build antennas with material form here

Test our cantennas antennas: 2 km without problems

In bamenda there is no industry, but very good and skilled manufacture so they make container form old container. we can give the dimensions we need and they do it. so our friend present our first cantenna antenna


this antenna was build on the base of the book Wireless
Networking in the Developing World. This book can be
downloaded from the following internet page
http://wndw.org/ From this book we build 2
cantennas antennas (see chapter 4 page 33). we take the dimensions of
the book, but we had no N connector. we had a original linksys cable
with a loss of 5db for 9 meter. we take 2 of this cables, because we
can plugin in the linksys router and we just put  the cable inside
the container and we tight it. when it was finish, we start testing.
Just beside of the satelet dish we had a internet connection, we plug
in the linksys. on the other side we has a notebook with the second
antenna. First we test 300 m distance and it works properly, form this
point to a restaurant. so we test further. we had a good position on
the top a little hill and on the other side it was 3 stage
building.  We ask to make test, but when the responsible see a
white man in the group, he want 20'000.- cfa (~35.- euros). The africa
friends, who made the test were ashamed and we decide to go elsewhere.
it was a catholic church and the allow us to make the test and give us
electricity (our notebook has no good battery, so we need always
electricity). The distance was 600 m and we could have internet. So we
test more... An internet cafe was on the way and a friend of us know
the people, so we could make test there. it was working too. we get
internet and here you can see a part of the ping
protokolle.
