Hello All,
In Sydney we have two what are really WiMax systems available for
public use. Their protocol is not strickly WiMax at present but they are
hardware compatible and the WiMax protocol will be downloaded to the users
when the software is available.
One of these systems has 84 base stations in Sydney.
If an amateur club or group of clubs could purchase one of these base stations
which I understand run about 25 watts on 3Ghz and either specify it for an
amateur band or transvert it to an amateur band we would have a better wide
coverage system than WiFi.
I presume the design would be frequency agile because in different countries
or even areas of different countries different bands would be needed.
The user receivers are quite cheap from a number of suppliers in Sydney.
My son is using one of these systems and finds it very fast. Faster in fact
than ADSL.
Under our regulations we could push up the base station power as much as we
could afford. Likewise with the receivers modem a transvertor with higher
power could improve the range considerably together with high gain antennae.
I believe there is room on 1200 Mhz for one of these systems
which could support most amateurs in a city.
Worthwhile the experts looking at this ?
