So Marlon, using what I perceive to be your ideas below, it's not
too bad of
a deal to put a "marginal" customer on (maybe not at -90, but maybe
-80 or
even -85, or do you think -85 is not even good enough?) so long as
we have a
clean link and we can make it with next to no packet loss?
In my situation, I'm selling mainly 512kbps connections. I have a
few that
want a full meg, and one that may be looking at 3meg shortly, but
I've got
mainly resi customers at the moment. I'm finding though, that I can
beat up
on DSL pricing for businesses here so I'm starting to hit that market a
little more. But, I need to be sure my system is stable before I
really get
into this.
I appreciate everyone's feedback on this topic. I haven't figured
out my
issues completely from my original post, but they have actually
cleared up
somewhat. I'm starting to actually wonder if I have either a bad
AP, or if
I have water issues as it seems like it was acting up in the middle
of the
afternoon, and then again later at night. Beyond that, we have good
solid
consistent ping times (5ms or less) to all clients (yes, even the
one with
a -90). But, again, haven't had any problems in about a week.
Waiting for it to cool down a bit before we put in our backhaul
(this POP is
on top of a water tower).
Which brings another question, how high from the top of a water
tower would
you recommed mounting the antenna? It's a PacWireless 13db
Omni-horizontal.
It's a "cylinder" tower. Right now the antenna is mounted directly
onto the
ladder railing on top. We're going to raise it up 5' or so when we
put in
the backhaul too. I'm thinking that may help keep things clean too,
as well
as give me just a bit more range with it (one side is partially
blocked by
the "dome" on the top middle of the tower).
