Hello Mark VK3JMA has made some suggestions for using the 2.4Ghz gear that is
commercially available.
Mark, what do you propose as a network geometry ?
It seems to me that to cover a large part of say Melbourne or Sydney a small
number of sites would be needed but the amateurs who would be using this
system will be in all directions. Which is why I raised the problem of power.
Another question; How will transmitter identification be done ?
My understanding is that they use TCIP. However that will not do for idents.
Can we get at the programming for these devices ?
Its true that the band is shared with class licenced users. However if we want
to tie the network we developed into the wider amateur network it would need
to carry the appropriate identifications.
I know this is getting ahead of the game somewhat but we will need to have
some idea how we can acheive the legal requirements.
From memory I think the lower 8 or 9 channels of the class licence channels
are in the amateur band. This means we will need to prevent other users from
using our system. I think we can do this using the 44.x.x.x addresses.
Is this so ?
There is a section of the ARRL web site devoted to these techniques so there
maybe something there about idents.
