Thanks for the responces, the proposal as rightly said is no different
from Wireless networks deployed by ISP in small communities.

I think you are zeroing-in on a plan that will work. My point is that a
20Km radius is NOT a small community. While the VSAT link may have
sufficient bandwidth, your wireless distribution system may not.

It would help reduce the load by using a higher bandwidth method such as
fiber, to interconnect the various local wireless base stations to the
VSAT terminal, rather than using the wireless systems themselves for
inter-site distribution.

Remember that a wireless system's bandwidth is divided among all the
users. As more users access the network at any one time, the slower
will be the response.

Just to chime in on this topic, I think some incorrect information was
passed along regarding legality of transmission power - the FCC does
in fact limit unlicensed maximum transmission wattage on the 2.4Ghz
range, however the use of high gain antennas is NOT illegal. You can
use extremely high gain directional antennas to achieve links over a
20+ mile LOS link, and still be within legal limits for unlicensed
operation. Think of it as using as talking thru a funnel - all it is
doing is using that same power more efficiently and more focused. Now
if you are talking about running the signal thru and actual signal
amplifier, then yes, that would be illegal.
