Perhaps this is a fit for Outernet ?

Hello Alessandro,
To the best of my knowledge, there is no AMPRNet infrastructure in
Bangladesh, so there is nothing for you to connect to using network 44.
While it is true that amateur radio can communicate over long distances,
it can only do so at extremely slow data rates, far too slow for internet
use. The only way I can think of for you to accomplish the connection
you seek is to use satellite communications. There are indeed amateur
radio satellites, but none of them handle the kind of data that would
be needed for internet use.
I believe you will have to get your connectivity via one of the commercial
or government satellite services. In the USA, this is not expensive,
but I have no idea how much it would cost for Bangladesh. Perhaps you
can find a charity that will fund or donate the necessary equipment or
service.
I wish you the best of luck.

hello everybody,
let me shortly present myself and the matter: working in IT for more than
30 years,
experienced with network devices (switch, routers, firewalls,
IDS/IPS), programming (C and some others), good knowledge on protocols and
RFCs; hosts under my control are not allowed to run anything else than
FreeBSD.
but absolutely not experienced about radio transmission/devices/requirements
so had
carefully read http://wiki.ampr.org/wiki/Quickstart and feel it is
not suitable for my problem: I am looking how to arrange for an
internet-connected PC located somewhere in a remote village of Bangladesh
with no local power source.
while it seem almost easy to power the PC with solar-cells battery is it
not clear
for me:
- if and how is possible to use 44net to internet-connect the remote site
via RF,
feel it just a matter to have sufficient "radio power" to reach a
44net bridge, a PC/router and some radio devices but unsure.
- what kind of radio devices are suitable for that use
(or: how far can
radio waves go with a "poor" power source?)
- locations (if any) of local-radio-amateur joined in
44net that can
bridge some internet traffic from/to such a "leaf-site"
moreover my limit are:
- money: while it's a personal initiative have no founding except my
incoming
and thus cheap is a must
- reliability: can't be on site to fix any
possible problem as them
arise, so "good" devices are required
as stated in RFC1925 : <<good, fast, cheap: choose two, you can't have
all three>> implies that am aware that "fast" can't be get; just
need
directions and some "good" reference for the HW where I can learn details
as power requirements and for the SW (but I guess 44net is the right place).
wish you nice day
$witch
