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

I suggest not using PC to connect to the AMPRNET
get a small mikrotik router it support IPIP it operate on low voltage and consume nothing I have it working here with this setup
as for connecting radio you can connect with wireless lan as the fellows do on hamnet see here https://hamwan.org/
by that you will get high speed and wireless gear dont take too much power its less the 25 Watt 2M radio
Or U can connect to 9600 Baud or 1200 baud on VHF and UHF ham band and work Packet radio (i personally not recommend due to the low speed)

thank you Ronen,
I suggest not using PC to connect to the AMPRNET
get a small mikrotik router it support IPIP it operate on low voltage and consume nothing I have it working here with this setup
well, that's nice but a PC is still required and while FreeBSD is able to use IPIP I also guess there is no real need of a dedicated routing device while the encapsulation can be done by the OS itself; but it's a detail, will anyway check more deeply.
as for connecting radio you can connect with wireless lan as the fellows do on hamnet see here https://hamwan.org/
mmmmmm it' seem not possible, byway of their site the hamwan network exist only in U.S.A. and somehow in Europe, but I want to connect a village in Bangladesh.....
by that you will get high speed and wireless gear dont take too much power its less the 25 Watt 2M radio
feel no kind of AP are around, maybe satellite connection is a better option
Or U can connect to 9600 Baud or 1200 baud on VHF and UHF ham band and work Packet radio (i personally not recommend due to the low speed)
it sound better.
while "cheap" and "good" are in place I can loose "fast": is it clear that such rate is very low for today's web contents but have personally worked with IBM S/1 with 300 Bps RS232 and plaintext is suitable for that rate; as soon as plaintext email can flow the main goal has been reached.
will look around for both VHF and UHF devices.
best regards

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. - Brian

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.
