Greetings;
RF Only is a very difficult sell these days. One reason being you can buy
a decent used tablet or smartphone for $100.00USD or so and put it on a
plan for a few bucks a month for access - and it's RF. A series of radios
for point-to-point links (as used on EastNet), decent TNCs, hardline/coax,
tower/masts, and beams can get pretty pricy not to mention whatever you
plan to use for a controller... and for only 1200 or 9600 baud (at least
in the USA) makes it a _very_ difficult sell to a club or an individual.
It's quite doable with decent used gear and if you're persistent so you
can stay away from wired links as packet "networking" is using one radio
to come in on, so you may go out on another radio. Point to point links
are used so that you eliminate "hidden transmitter syndrome" and free
your network of packet collisions.
If you decide to look at FlexNet, there's nothing much to set or configure
with it. There's no NetRom overhead so your data will seem faster than the
bauds you use, and there's no fuss or muss with qualities. It uses real-time
ping frames and calculates a round-trip time to live and it adjusts the
quality/time of the link by real time response. You don't have to set
or adjust anything there.
On FlexNet you can expect a 30ms RTTL quality on a point to point link
at 1200 baud, while at 9600 baud you can expect an RTTL around 8-10ms.
Using a TNC3 I've been able to get RTTLs as low as 5ms at 9600 baud and
data flows through almost as fast as if the remote end was local.
Defintely something to look into!
