Hello,

If anyone knows about any project related with simulation models for
GSM and cdma2000 (physical layer) please send me or post the contact
information for that or those projects. At Universidad del Valle
(Colombia) we´re investigating on those techs, because are the ones
installed in the area. Thanks!

Subject: measuring antennas gain

lcamacho@...

Hi friends:
I have been thinking...I do not have RF Generator and Periodic/Log
Antennas....but I have APs, wireless cards and 24/19 dBi grids antennas.
If I know the transmission power (of AP or wireless cards), the antenna
gain (24 or 19) and the distance transmitter-receiver ¿why  I cannot
calculate the gain of an antenna under test? or ¿can I do?

what do you think?


In the other hand, I would like, if somebody would send me the Short and
Long  Distance  Links  Reports  ... I am sorry,  I lost  that
information...very thanks in advance...

Best Regards

Luis

Subject: using Spectrum Analyzer Agilent ESA 4404B

lcamacho@...

Hi!

I am measuring the output power of wireless cards and APs. Mi procedure
es to introduce directly  the output (antenna conector) of the equipment
to input of Spectrum Analyzer (ESA).
I have two problems:
1. I do not have doubts for insert to ESA; 14,17 and 20 dBm wireless
cards. The 4404B resists until 30 dBm (but 0 Vdc)...but I fear introduce
30 dBm exactly...4404B have a input attenuator but...when I introduce a
signal, the value power displayed in the ESA screen does not  change
although I vary the value of attenuation..I do not know what happens.
¿how I could be sure that the internal attenuator is working? Of course,
with an external attenuator, I would not have problems, but, I do not
have one!

2. When I introduce the output power of a 17 dB wireless card to ESA,
the signal is not continuos, the signal hop hop in an interval of 100
MHz...it is normal?

I am attaching an picture of ESA, I get this image changing the typical
value of Sweep Time (4 ms)  to  2 s.

Best regards

Hi all!
You can upload photos (and I am very curious to see them!!!) using the
Photo item on the menu on the left of the ICT4SD page. You must have a
Yahoo account to be able to upload the photos. You can also upload
general files (as for example documents) using the Files item of the
same menu.
Looking forward to seeing your photos!

Subject: Rural Telecommunication Project.

labdala@...

Dear friends,

We met at School on Digital Communications for research

and training on developing countries held at ICTP in February 2004.

I am reading a lot about Jhai Foundation and Village project, additionaly other rural projects.

We are developing a similar project to offer telecommunication services

to rural communities in Venezuela. The community selected is placed in Andres Eloy

Blanco district. It has a population of 42.067 people. It has three villages

called Pio Tamayo, Quebrada Honda and Yacambu. The table below describes

the public services.

Type of Service	District Andres Eloy Blanco	Parroquia Pío Tamayo	Parroquia Quebrada Honda	Parroquia Yacambú
Power Service	74,14%	90%	31%	56%
Water Service	54%	74%	18%	20%
Toilet service	51%	73%	7%	15%
garbage service	37%	58%	1%	1%
Telephony fixed	8%	12%	0,80%	2%

We want to offer to schools and medical surgeries: internet service, Voice over IP, e-mail, etc.

I need a piece of advice about what hardware use for school stations.

I thought to ask Pentium IV with typical monitors that costs about 1000 $,

but I saw that you built your own systems. How much money did you save doing that,

because you used LCD monitor for saving power but this monitor costs about 800 $.

Do you think that is better to use LCD monitor in my case? Or is it better to use typical monitors

-I think that is better to use typical monitors because we have enough power energy enable-

Therefore, we want to offer VoIP but I don´t know a lot about this technology. I have read

in the slides presented in the school that you used Quintum PSTN Interface, but

in the slide called future VoIP, you said that you want to use Quintum or

Digium Products to replace Quicknet LineJack PSTN Card, why do you want to replace this card?,

what advantages does it have?. What sort of card do you advise us to use for VoIP system?

Could you please tell me what are the best products for VoIP?.

Thank you in advance for your help.

Salaam Ahmed,

Thanks for your quick response.
My names is Habibu Atib. I am new to this area of
wireless computing, so haven't done much yet. Though
my interest will be much inclined to security element
of it. I guess you have done alot in this area, as you
mentioned in your previous email.

What are some of the security gaps that exists in this
area of wireless computing. I welcome ideas from you.

Have a nice evening.

Regards,
Habibu

Please am trying to identify a research problem for my PhD within the
