So you are looking to setup a small time Wifi ISP (Freenetwork)?
I don't think it is problem as long as the anttena is in line of sight and signal strength is greater than -10 db
Its in a preliminary stage only. I do not know about the legal side of using this technology. Anyone aware of it.
U are not allowed to do an omnidirectional broadcast in the 2.5Ghz band (u will screw up everbody elses rx/tx). Licence fee for point to point link is/was Rs75000/-. U require cleareance from the DOT WPC division and NOC from the police for yourself and for your client. U would have to obtain SACFA clearance for location of antenna if antenna height exceeds 3 mtrs above the sea level or above building terrace.
And what about various goverment agencies involved for such a project to setup apart from Department if IT. Does it come under say FCC etc. Also Would such a project be subjected to say some ISP act or something.
If u are an ISP u have to use the 5GHz band. Connect the 2.5Ghz card o/p to an upconverter and PA to generate 5Ghz.
Actually this is intended to be a community project only and not commercial as such. But there would be a small fee to join such a community and as such it will not be free in that sense.
That is a commercial venture and will cost u substantially more in licence fees, to be paid to the DOT WPC.
However afaik the wpc is not monitoring the 2.5Ghz band. And point to point links go undetected.
and if u wanna go global try 25Ghz moon bounce. Or 150 /300bps shortwave with a 200w pa. Plaintext mails properly trimmed or text chats should work well.
