pics of another interesting wifi connection...


This is the tanzania electricity supply company, tanesco, office in Kayanga. Notice the surrounding tall trees and the small office building below.

The parabola antenna up in the tree majestically looking towards the Internet station. We cleared a few branches to have "signal breathing space" for the antenna! ;)

The linksys wap11 getting a dressing in a 5-litre jerrycan, easily available water proof box! We later heavily covered it with tape, to keep out as much rain water, fog & bugs as possible.


Coming down the huge eucalyptus tree, after climbing 50 metres above ground. I never intended to do this but its always a wise idea if you ever want the connection to come through. Other people imagine that they are seeing where you want the antenna to point, but in reality, they are just imagining it!! Another way to prove, "if you want anything done right, better do it yourself" ;)



This is the view from the top of the eucalyptus tree infront of the tanesco office. Notice the so many surrounding masts. In the foreground, is the celtel mast; middle, national telephone company - ttcl mast; and in the background, tigo mast. Celtel & tigo are mobile phone companies offering gsm. The tigo mast is close to where our small mast with antenna is.

The 3rd node & home town now bathed in wifi!!

This node has been amazing! Its something i never really had on my mind at all on doing. The next step was to setup an omni antenna and have whoever wants to access internet via a wireless network card drop in for the signal now and then. Just as I had just finished doing this, a friend and manager of the local electricity supply company, pops up at our office ready to sign up for Internet at his office, 2km away by road.

This would not be a problem at all, but his office is in a valley, total out of line of sight. But upon survey of his site, we realized he got quite a number of tall trees that could hold our antenna as we run down the cables to his office. But still, I was skeptical that we could get a good line of sight considering so many other tall trees around and infront of his office.

Having the long range multi client bridge powering the omni antenna at our base, I could confortably pick up its signal upon climbing nearby tree, about 50 meters off the ground. Well, this gave me strength to have a go at the connection. Having two linksys WAP11 radios lying around, configured one at take its position in the tree at the client side.

The 1st day, mon 12th, was all in vain, as it could not pick up any of the signals. This quite puzzled me alot and made me dig up more on how to configure the WAP11 plus whether they can interoperate with the senao driving the omni antenna at the Internet side. Reading the wap11 manual completely, solved the problem, as it clearly states, the wap11 cannot operate with any other access point unless its one of its own, that is, another wap11 on the other side! Well, i quickly configured the other wap11 and fixed it on the omni antenna on the internet side and prayed that it is powerful enough to push the signal that far.

And am now happy to report that it did not disappoint. We now have the remote site connected to the Internet and the manager is really happy.

Sharpen your IT skills @ the Wirelhttp://www.blogger.com/ess Community Camps this summer!

I have had quite a good number of good blog followers in and around africa, according to my blog stats. Some of these are known to me, either from past IT workshops, email, msn and others are strangers.

To the IT guys who do read IT stuff that i post on this blog, allow me to pose a few questions to you;
-Do you want to improve your current IT skills?

-Ever had the interest of sharing and learning IT skills and experience within a limited period of time?

-Want to know, learn and experiment with the latest technology in terms of hacking, Operating systems, etc right from the experts in the game?

-Enjoy IT talk?

-Would you like to join "elite" IT forums with "kool" IT experts who are known to you, help you with everyday IT challenges, share new ideas?
Well, this and more is what you always find at the wireless community camps that are organized in europe. 2006 was great for me because, i do not regret attending the Djurslands International Institute of Rural Wireless Broadband, DIIRWB and wifisoft.org organised community camps. Today, am setting up long distance WiFi networks with skills and plenty of support from friends that i met during those two camps.

Join the mailing lists of wifisoft.org or better still check out their website for more info on how to get involved. Email me if you feel my experience in attending last year's camp could be of valuable help to you.

At these camps, there is always a multitude of people from different parts of the world who are ready to share their experiences on using Information technology, for instance; Germany, UK, Denmark, Netherlands, Georgia, east Africa, etc
