Hi Peter,
I hope you are aware of the OLPC project, because you seem to share
some of the same goals. See
http://laptop.org/
Yes I'm .... and HCL is taken up into manufacture it
setup a USRP1 based BTS .. which might cover near
by villages also.
With 11 dbi Anettena and appropriate PA . we can do it up 5 to 10 KM (
send a mail to Ettus)
Did you research other RF interfaces than the one used
by GSM?
Yes , and are legacy . need higher bandwidth.
and Why I'm not thinking for Armature radio or Air broadcasting .. it is
only One way..and other drawbacks
do you have any suggestion ?
>> Define cheap and small bandwidth?
They
have very cheap equipments ( out of store almost) for providing low
bandwidth. like 64 Kbps, 54 Kbps even 9 Kbps RF interface.
on demand they can supply.
you will be kind enough you you give me other cheap solution after all its
all for charity..
rather then GSM ,
and one more cause to attract me here is in some places we have GSM
infrastructure and , Govt and some private operator will let us user some
part of it.
Kind Regards,
