Well, I personally could care less about the dish,
but Direcway doesn't offer a megabit connection on the smaller dish.
Nor does the Direcway Small Office specifies "up to" a megabit.
Once again, what you're getting with the bigger dish and additional
monthly charge - are "enhanced uploads" and a 500 megabyte FAP
threshold with a 56 kbps refill rate. (Smaller dish gets 47 kbps
refill rate). You'll find little or no difference in long term
download speed averages.
Granted, Direcway only advertises "up to 500" kbps for the smaller
setup. But they use the very same modem, and the very same
bandwidth. Shared bandwidth. With my 74cm elliptical dish and
consumer plan, I typically receive in excess of one mbps. On good
days, it's over two mbps. On rare occasions, I've downloaded
simultaneous bit-streams (4-5 files from the same server at the same
time) in excess of six mbps. But when it's bad, it's bad. When too
many people are "up" at the same time, it can drop well below 100
kbps. Upload rate code is fixed at 1 (up to 128 kbps), but as I've
already told you - that's a horribly inflated number.
My point? Same modem on shared bandwidth means you're not going to
see any noticeable difference in download speeds between the two
dish sizes. But by design, the bigger dish gets more of your
transmit signal to the Direcway gateway - permitting the modem to
switch between upload rate codes 1 and 2 (up to 256 kbps, also
horribly inflated), depending upon atmospheric conditions. The
business plan part buys a line of code in their server that raises
your FAP threshold/refill rate. But your received signal is included
in the same 48 MB broadcast that everybody else receives. Simple
fact of the matter is, the more users that are "up" at any given
moment, the less of that 48 MB each receives. Shared bandwidth.
