When you say, "absolutely not experienced about radio
transmission/devices/requirements", I take it that you are not an amateur
radio operator.
Amateur radio frequencies and the AMPRnet are for use only by licensed
amateur radio operators in accordance with their local country's laws for
the amateur radio service. I don't know the laws in Bangladesh, but it's
likely that, unless there were a licensed operator present in the remote
village you mention, it would not be a legal solution.
Also, amateur radio in the US and everywhere else that I'm aware of does not
allow encryption. But most of the internet is moving toward encryption:
websites, email, etc. So, accessing those resources via amateur radio would
be illegal.
Lastly, speed is an issue. Browsing today's websites requires a lot of
speed, something that just doesn't work over 1200 baud or 9600 baud or even
56 kbps (which is coming, but not even available yet). You could go faster
in the microwave frequencies, but then distance and line of sight are an
issue and you still need a licensed operator and no encryption.
Bottom line, amateur radio is probably not a viable solution for your
application.

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
