first CWN international link

Hi!

Good news! We (well, at least I remember me and Mitar) were talking about the possibility to connect
Slovenia and Croatia and Austria's wireless community networks together via Wi-Fi (well,
theoretically we could end up in Greece . This was a dream at the wireless summit 2010 in Vienna. Now,
after some planning, this seems to be on the edge of being realized!

Please take a look at http://grow.wlan-si.net/wiki/Dogodki/2011/07/WirelessLinkTestingDay

In case you want to participate and live in the area, please get in contact with Pridi (as described on the web page)
or Mitar.

Woohoo! Cross country Wi-Fi connections :) Here we go!

Re: first CWN international link

Hello,

It is certainly going to be a fun time because it is a long range connection. For wireless it does not matter whether it is cross border link. I wish for the success of the project.

In Nepal, the longest link we have made is 52 KM from mountain top to another mountain top. Your's is going to be longer than that.

BTW, if you find the equipment reliable one, please let me know. I will also try them.

Re: first CWN international link

This write-up appears to suggest that things like TCP ACK might end up limiting your throughput down below what is useful.

http://www.radio-active.net.au/web/80211/distance.html

I'm guessing you would need to abandon TCP for such a long link.

TCP will work fine at such distances, but there can be link-layer
problems.

The per-frame acknowledgement in 802.11 was not a great idea even in
802.11b times.  ISTR that options were introduced with 802.11n to use
fewer acks.  Block ACKs I think that it's called?

You can also diverge from strict 802.11 constants or protocol to make
such a link work.  For years, NICs have let you fiddle with the SIFS and
other parameters.
