Very often I'm being asked how can we aim such long distance WiFi links.

A relatively simple way of doing this would be to use a high-power analog signal transmitter fed into the antenna on one side, with a spectrum analyzer identifying that signal on the other side.

In our global village world - we can find the above for less then $300 (total for both sides), which conventionally would cost way over $10,000:

Buy a high-power 2.4Ghz video transmitter from:www.chinawholesaleonline.org
At first - I was a bit worried to give my credit-card on an unknown Chinese web-site. For once, I'm happy that I was brave enough. The owner of that site - Adam, had dispatched the transmitter immediately, and I got it days later via DHL. However, the unit was faulty, it would often not turn-on, the frequency would not be stable and would shift with temperature and the power was less then 300mW.
For a moment I thought to myself that I deserved it for buying from such an unknown source. However, I have emailed Adam, and he had quickly <"read more", to continue>

Here is the small transmitter being measured with a spectrum analyzer to establish the power. Look at the nice and stable analog signal which is so easy to spot on the far side.

My talk at UC-Berkeley, could serve as decent and current source of information about AirJaldi.
While surely not my best talk from a personal point of view (my excuse is that I was sick and under-slept),
I did got to address many issues tanks to the questions from the audience.

It's an hour long and no commercials ... Enjoy:

This post is long due, but like they say - better late then never.

Following the AirJaldi conference (end of October 2006) David Rowe came to visit us in Dharamsala, all the way from far Australia.

David is leading a unique and exceptionally important project of revolutionary potential: Free Telephony Project

While many of us are still getting used to, and learning the concept of Free / Open Source Software (F/OSS), David's project introduces additional confusion, yet equally innovative concept: Open-Source-Hardware

Finaly, the new server for AirJaldi is installed and is ready for service.
In fact, if you see this page - it means that it's still working ;-)

Well, this is what it looks like ------------------->>>

The server is hosted in Hurrican Electric farm in Fremont, Califronia.

The new server will host all sites, content and services related to AirJaldi. In addition, pending bandwidth and time constrains, we welcome all Tibetan non-profits and other non-profits affiliated with us to host their sites with us. The machine is managed by a group of volunteer system administrators from around the world.

Thanks everyone for the hard work in making this operational.

The year (2007) started with Mikey's visit to California.

The plan (which did happen) was to go over the year's workplan and genrally do lots of talking...
As per the AirJaldi tradition, talks must be accompanied with actions - so Mikey was draged to the roof to get some work done...
