Field Activity Day & Discussions
*I am happy to take part in updating the dairy on a very special day, where all the school particiants exposed how to establish a link with an access point being far away from the location. It's a good learning method. Thanks for this Oppurtunity.
It is a very good idea to have a check list before going for the activity.

...Its rainy day from afternoon.
The real spice of the school is in practical training Hands ON expereince.....
All are assembled in the lab at 08:30 AM. It is becoming little easy beacause of the background work done by the all teaching group in the lab in listing and packing the equipment needed for the field activity. Thanks alot for this....
We started from the lab at an about 08:35 AM towards the AGH with all the equipment on shoulders... it's a good idea will be helpful to work on our own.
All the way, while walking with equipment, reached AGH, at about 08:55 AM
Till now we dont know about the items we forget to take to the activity. Hope we have taken all.......
Bus came to AGH, boarded the bus, it's a very good transportation arrangement made by the organisers(my opinion).
Reached there at 09:15 AM, taken all the equipment and gone to the actual location.
Oh... first problem we observed is, forget to note the Azimuth and angle of the transmitter location.
Anyway we overcomed this problem this, using the Compass, MAPs? , and other tools.
At 09:40 AM, Now all of us started to take part actively in erecting the Antenna.
We carried Spectrum analyers with us used to track the channel of transmission from the other side.
Chosen one good location to mast the antenna, Here we have taken precautions, for CLEAR SIGHT & Fresnal zone, it is to remembered always while erecting.It is better to mast the antenna at the cliff.
Antenna erection is completed at 10:00 AM, it's a time we are all searching for the signal, using Netstumbler, Omni-Directional Antenna, Cantenna, and also using the Mini-antenna with the Spectrum Analyser, but still we didn't....
Trying with diferent antenna's atlast using the Grid antenna we got the link established.
Lot many questions, raised by the participants and they are all cleared by the teachers. It's a good place for discussion while having practical exposure.
Link was established, Using linksys box Group Two succeded in communicating the with the other side.
It's an nice thing that was demonstrated by the Mr Rob, using his Apple MAC Laptop using the IChat? Feature and Webcam, we used to see the Carlo, Thomas, & Struzak at the other side using the link.
Further after,using the linksys box already configured earlier by Group One, they made the link with GGH, which is followed by the group3. All of us worked together in the field activity learnt a lot, in established a link.
Now at last in the field activity, we have changed the Antenna, and tried to establish the link with the CANTENNA, it was designed by the participants on their own, with a cost of around 3 Euro, Oh...... we got the link established to the other end.
Good packets recieved, Pinged the link 192.168.1.1, and we have the long distance link established with homebrew antenna by the ICTP School participants in the lab on 13 Feb 2006.
Each group has taken their photographs, and along with other groups also, and ofcourse weather is worst compared to other days, it's too cold. But all of us alerted by the Carlo in the earlier day, about the weather, we have taken precautions. Thanks to Carlo.
Succeded in establishing a link with all the co-operation...Hip hip hurray..
We packed all the equipment carefully, and boarded the bus, and reached the ICTP gate. It might be a good idea if the bus drops us at the GGH, we reached the destination at 12:00 noon by walking along the road from the ICTP gate, we all are tired alot
It's a luch time yaar......
After assembling all the participants in the class Carlo and Rod, started and discussion pros and cons of the day activity, and also warned all the participants about the preliminary precautions to be taken during activity. All of us noted the requirements.
But the evening session is not that much intereted till Coffee break because, we were left for free to prepare reports......
Rainy day
Till the end of the session we were engeged in report preparation.
At 19:00 hrs are all gone for dinner. Some of us worked in the lobby computers.
This is the first rainy day after the school started ended with very happily, each ofthe participant acquired knowledge alot because of the fried activity.
Good Night........
