The "problem" with satilite is the
circuit path and distance. went you load a page when surfing the web
you actually have several transaction taking place at once and some
complex pages have a lot of them. Each transactionn or data stream has
to be acknowledged to process completely and with sattielte you have
at least two 22,500 mile paths in the down load (actually longer
unless you are right under the satelite) and if it is 2 way you have
another set of 22,500 mile paths for ack's and uploads Just to travel
this distance you are looking at a latency of over 1/2 a second just
for the time it takes for the radio wave to travel the path. Add to
this the latency added by conversion from RF to digital data stream on
wire to ground based servers and then the back bone and the server you
are downloading pages from you can have a latency that easily equals
or exceeds 1 sec


Bull***.

No BS at all but I can see where someone that does not know how things
work can think otherwise. 700+ plus milsec is a VERY, VERY long time
for a ack on a network (300 ms is considered pretty slow) My ping
times to local server here average 60 to 80 MS last time I checked it
(I have seen it as low as in the 40ms range) so you have about 10x
the delay of a normal broad band contention. Dialup is usually in the
100 to 250 ms range. Also this delay is far more of a factor that you
realize in web surfing but people like you only maybe know how to turn
on a PC and open a browser and type in a URL but do not have clue how
it really all works and call it BS when some REALLY knows how it works
explains it and since it escpaes you abilty to understand it in you
mind it must be BS. Very sad. It is not like opening a water tap and
data starts flowing as everything must be handshaked and that takes
time at 700 MS ack times. For expample CNN web site showed over 40
data streams on a refresh of its page to fully biuld it. While it is
try that you can down load several streams at once, there is limits
with you browser and server as to how many you can handle at once. If
you are using FireFox or Netscape you can try the tweaks in the link
below and that will enable pipelines and multiple transactions and it
may improve your web performance on satilite Internet. (Or you can
just call that BS too and muddle along) I use it and it can snap
things up even further on a a good broad band connection.
