I remember hearing about these though I'd consider these to be somewhat of
an oddity. again why 70cm, only 30MHZ wide & already filled with other
users? Why is everyone so damn scared and afraid of moving to the amateur
microwave bands where we have 1555MHZ of mostly unused spectrum from
1.2-47.2GHz? Why must we recreate the wheel so much of the time when it
may be better, faster, easier, & cheaper to use directly or adapt a
solution already in use in another service.

There is a company that makes PCMCIA Cards that work on the 70cm ham
band give out up to 0.5 watts and give high speed data rate (dont remember
exectly how much but few mb/s )
that can serve for wireless link for tha ham community ....

I like your thinking. I have looked into similar solutions such as
Ubiquiti
wireless devices. They have wireless devices that can be
configured
out of the ISM band and into the ham band with no mods. Plus they are in
the
sub $100 range making them a viable option. I have also played with some
converted Linksys devices running HSMM-MESH. All great in theory, but in my
case, I am an island. There are no hams in my region that would see the
benefit or interest in such endeavors. They are more than happy to get
their
DX and go to bed.
Anyone in Northeast PA want to link up with some kind of RF/wireless and
extend
the Amprnet?

> It would seem Linux and Ethernet whatever architecture it's running on
would seem to be the best solution available for routing Net44 at the
moment
and it works well. a standardized plug and play package of hardware sold
by
your local candy store would be nice but we're only partially there. Being
that 44NET/Amprnet is supposed to be a RADIO BASED IP NETWORK (or at least
interconnected islands of RADIO BASED IP NETWORK) we seem to only have half
of a standardized solution to offer. It seems that we have forgotten the
RADIO part. Given a live piece of cat5 with bits on it that I wish to have
show up elsewhere what can we offer to the average ham that can go on the
tower with Ethernet in one side and an antenna on the other, especially
something standard enough that a local group can set up a network with?
The
only thing I can think of that even comes close is the professional grade
802.11 hardware that's out there. (much of the consumer stuff lacks the
configurablity !
we could really use such as power control and
timeouts). I might
propose
that we standardize the RF interface for AMPRNET on an agreed physical
layer
(of 802.11 unless something else is proposed and made quickly and cheaply
available) and a relatively standard stack of hardware and software be put
forth as a package that could be turnkey deployed by interested parties.
What would others think of embarking upon such a project as a group? who
might be interested? and what might we offer? (PS. I know of at least
one
manufacture of gear that would be quite happy to mod a standard product or
products so as to have them better fit the amateur radio band plan and
channels on a couple of our microwave bands as well as make provision for
the ability to get significant QRO above the 25-30dbm out that seems
standard. This in production batches maybe as low as lots of 100 units)
