Default Real noob questions

I live in a small rural town in the backwoods. We have phoned
internet and a wireless provider.
The wireless antenna is about 800 meters away, i can see it
from the roof of my house. From the roof to my router (I use coyote on
a dial up) measures 4 meters.
From what I understand I will need an antenna, cable, a
pigtail and a pci wireless card.

So here are the questions:

Antenna -- would a simple wire antenna pointed at the source
be adequate ? Or one of these semi-parabolic antennas ? Like these :

http://www.gtnet.com.br/images/fotos_produtos/98.jpg

http://img.mercadolivre.com.br/jm/im...1_6148.jpg&v=I

Cable - a lot of people here use RG 58, and say that at short
distances like 4 meters the loss is very small, 10% below a RG 213 .
Is this true ?

Pigtail - any secrets ? Do I need one if I use RG 58 ?

PCI wireless card - is there a cheap , good, all-operating
system chipset, like the realtek 8029-8129 are for ethernet ? I intend
to use it under linux and windows.

I've browsed dozens of pages, but most just sell. Few explain
anything at all.
TIA

First ask the wireless provider what it takes to be a user.

As DTC said, you need to contact the provider to see what is required.

Just because it's wireless DOESN'T mean it is 802.11x. Many companies
manufacture wireless systems that are proprietary, NOT 802.11. Take for
example the Motorola Canopy 900 system....900 mHz and ABSOLUTELY NOT
802.11x.

Furthermore, it's MY opinion that any ISP that wants to be reliable, and
appear to be not just another fly-by-night WISP, would NOT use commodity
802.11x gear.

Not necessarily -- you'll lose lots of signal in a 4 meter cable.
That's pretty far, and you'll probably need to avoid signal losses.
Better to use a USB, so no cable signal loss, and locate a USB wireless
adapter and antenna where it has clear line of sight to the access
point. Hawking makes a USB adapter with dish antenna that might be
enough to get the job done. Otherwise use a USB adapter with external
antenna connector and a high-gain directional antenna (e.g., bigger
dish).

I did, it takes +- one months salary for an antenna, 10 meters
of RG 58 cable, an old samsung wireless pci card.
http://www.samcoaustralia.com.au/sit...asp?prodID=120

Monopoly is a wonderful thing, if you are on the other side.
The guy hides as much tech details as possible, but I believe the
control is done by MAC address.

You get a 11kbps connection, for +- 1/10 of a months salary.
This is slightly cheaper than the phone option. Also the phone is max
5 kbs.
You have to give the equips back if you cancel the contract,
plus the balance of one years fee, if you cancel before a year is up.

So I decided to try to set my own one up. See how strong the
signal is, etc before signing up. No way I can hack here, pple would
turn me in very soon. So no worries there.
The questions stand.

(Sorry I use the expression "salary " instead of figures in
dollars, or whatever. People have no idea how low salaries are in the
third world)

A wireless howto anywhere ? All I found are more concerned
with lap tops within the house, or wardriving. Nothing like the
excellent linux ethernet howto.

Not available here, also I cannot see the provider antenna
from where I am, only from the roof.

Great links you sent. But ... they all think you are an expert
in antennas ....
http://www.freeantennas.com/projects/Ez-10/

This is supposed to be the easiest one, but there is no
mention on how to connect it to PC or even how to point it ....

I meant to put the USB adapter and antenna on the roof.

Granted its a monopoly, by definition where there is only one provider of
service. He's a monopoly because there is no incentive for competition. As
its HIS system, he has every right to be proprietary about it. Regardless
what authentication he uses, its exclusively at his discretion on who he
allows to use his service.

I really don't understand what you are saying. Even at the end of a long
telephone loop, you can get at least an 18 kbps connection (unless there
are sever line impairments - and you would definitely know that was clicks,
pops, and squeals on a telephone call. Even a cheap Walmart internet
account is on only $10 a month. So what you are saying doesn't make sense.

Annual commitments with an early termination fee are normal.

Be fore you even try that, you'll need to find out some very very basic
points of his operation.

And what did you find out? Is he locked in at 802.11B or g? What
authentication does he use (oops, you don't know that yet). 33 feet if RG58
cable, ummm...you need to study a bit more on cable losses.

HUH???? Why are you shopping in Australia?? Where are you from?
Try a Linksys Wireless-G PCI Adapter

And if you ARE from Australia? The laws there are entirely different for
wireless ISP operators. Are you sure he is operating a legal biz?

There's no real "monopoly" -- other Internet options undoubtedly exist
(e.g., dialup, satellite, probably others). By that logic McDonalds has
a "monopoly" on the Big Mac.

He uses 80211.B as the link I posted to the NIC card shows.
He uses MAC authentication. He uses an antenna like the one I posted a
link to, also RG 58 cable. I know, because I examined my neighbors
with a binocular and also asked about the cable. He transmits using
2.4 GHz
In the place I work at, this guy also provides the same
service. On a good, clear day it took me 10 hours to download the
slackware CD1, about 600Mb. He sells that as a 22Kbps link. In my town
its a 11Kbps link, so downloads would be around half as fast.. No one
else was using the net and i did nothing else but download. I cannot
examine the setup because he uses some kind of router on the roof and
the signal enters via ethernet cable.
If I take into account the salary differences, the guy wants
2000 dollars to lend me the antenna, cable and wireless PCI card, plus
250 dollars a month for the service.(a total of 3000 dollars a year,
what I have to pay if I opt out). So if I could set up my end of the
link, I would save a lot of money.
I have downloaded a lot of docs though the links that John

Then they aren't. No such thing as two monopolies. You would have to
argue duopoly, but even then there are probably other options.

Oh come on:
Expansys Brazil sells the Linksys WRT54GS-US for about US $100

The going price in the USA is about US $70.

50 dollars at newegg
And a minimum salary here is now around 170 dollars a month.
Is what > 80% of brazilians earn.
But we diverge. Wrong newsgroup. I was just pointing out
relative costs, which IS appropriate. No point in discussing what
software to use on the new moon based super provider with 100GBs
tranmission if neither of us will ever be able to afford it.

And if it WAS available, there is a 60 dollar shipping + 200%
import tax on it, not included in price. See mailing details. = 360
dollars

Nope, $70 (as I wrote):

Irrelevant.

At least get your facts/claims straight.

We are finally understanding each other :P
A kit with the antenna in my question, using 8 meters(I only
need 4 meters) of RG58 cable, and a ralink-chipset PCI card. And at a
good price.
So the questions stand :
The kit comes with 8 meters of RG58 cable, and no pigtail. Is
this OK ? The seller says that loss will be negligible. He also says
that there is no problem using up to 15 meters of cable(a question low
down on page)
Are Zinwell G361 cards good quality ? Are they compatible with
win/linux ? I have already visited the ralink site, it says the
chipset, a ralink 2561T, has opensource drivers. Anyone tried one ?
TIA

.................................................. .................................................. ...........................

KIT CLIENTE DE PROVEDOR WIRELESS 100% HOMOLOGADO PELA ANATEL
PRONTO PARA INSTALAR, CONTENDO:

- 01 antena PROELETRONIC 24 dBi (fique atento, existem antenas de
menor preço, mas muitas nem mesmo são homologadas.
TENHA GARANTIA DE QUALIDADE e perfeito funcionamento da sua rede
wireless por anos e anos sem problemas com oxidação do dipolo e
componentes e outros problemas que ocorrem em antenas de qualidade
inferior).

- 01 Placa Pci Zinwell G361 802.11B/G
54 Mbps com chipset RALink 2561T

- 01 cabo para conexão da antena diretamente à placa, evitando assim o
uso de pigtail e perda desnecessária do nível de sinal. O cabo tem 8
(oito) metros e já vai com os conectores montados. Montado com cabo
RGC58 + conectores N femea e SMA.

Nota sobre o cabo RGC58: Muitas pessoas afirmam ERRONEAMENTE que o
cabo RGC58 é muito inferior ao cabo RGC213 e que não funciona bem,
causa perda, etc... ISSO É MITO. Em testes TÉCNICOS, que executamos,
o cabo RGC58 apresentou inferioridade de 8% (OITO POR CENTO!!!) em
relação ao cabo RGC213, ou seja, se você capta 70% de sinal com o
RGC213, com o RGC58 você irá ter uma perda de 8%, captando apenas 65%
de sinal, o que praticamente não influencia na velocidade de conexão.
Quem realmente entende de wireless sabe analisar e comprovar a
situação. O cabo RGC58 é o melhor custo x benefício do mercado, além
de ser infinitamente mais fácil de trabalhar do que o RGC213.

Se você não conhece as conexões diretas com cabo RGC58, EXPERIMENTE !

?????. Since price is irrelevant in purchase, maybe you could
post me one free ?

I did.
Thank you for the Wiki links. I am studying them. Since I
cannot understand your logic, I will not be accompanying this thread
any longer. Bye.
