Probably not - that is, if we're talking about customers directly

It's the cost of consumer direct access to the satellites which is the
show-stopper and I don't see it coming down to dialup costs for years
if ever. 80% of the U.S. consumers with access are still using dialup
connections and most of 'em are not going to move to broadband until
the costs get a lot closer to dialup than they are.

While there's definitely a future for satellite comms, the
"last mile" problem combined with the enormous bandwidth of fiber
limits its usefulness as a general-purpose broadband access method.

Say you orbit a new, state of the art satellite. How much bandwidth
can it provide to how many customers?


A whole bunch. Even the old birds which have been up for years can
repeat something like 900 TV channels and those are not considered
high-capacity satellites.

Compare that to what is
available in a single fiber. Also remember that once the duct is in
place, pulling another fiber isn't that expensive, and that new
technologies permit more bandwidth in existing fibers.


What "ducts"?? There aren't any ducts running into farms and vacation
lodges out in the boonies. They'll have the last mile problem for
years to come. Until the phone companies replace their twisted-pair
wiring with cable, fiber optic and otherwise.

Absolutely. This is where DSL can really get the market, because with DSL you
don't need a second phone line.

That means 900 customers can have 6 MHz of bandwidth each. Or maybe 5400 can
have 1 MHz each.

When the satellite repeats a channel, it doesn't matter how many people watch
it. Internet bandwidth is a completely different beast.

Compare that to what is
available in a single fiber. Also remember that once the duct is in

I meant ducts that carry it to within a mile of the customer. Ducts that go
across the country, etc. Satellites can't create another RF spectrum.

Fiber and Wi-Fi...watch out...

One caveat!

A lot of folks are setting up their own little wireless networks. The stuff is
becoming cheaper than the cable it replaces!

But not enough folks understand the need to encrypt. Without good encryption of
your network, anybody can drive by with a lapper and access your network - and
your hard drives, etc. Your internet firewall won't help because your network
thinks the invader is *inside* your network, not outside. You need for the
network itself to be encrypted.

Where's my RJ-45 plugs?

And for good reason. In my new location, I'm terrified to drill
through the walls (it's an old *solid* house that predates cheap
sheetrock by decades) but I've no trouble using wireless.

If someone truly sets up their network in this manner, they are truly
running a serious risk, as you describe. I've just moved, so I have
to reinstall my network, and it will actually be set up with two
wireless access points: one for the "inside", which will be
MAC-restricted and locked down with WEP (until my operating system
fully supports TKIP in which case I'll go up to that protocol), and
one which is "outside" for any and all comers to sit in the nearby
park and reach the internet. No traffic goes to the inside from the
outside, and both sides can see the internet, so life is good.

N2EY Where's my RJ-45 plugs?

Put some time and effort into understanding exactly how to make it all
work properly, and you'll find that you need fewer RJ-45 plugs.

Oh, and I get that you're not talking about setting up your own
network in the encryption-free manner in which you describe. I'm just
trying to show that there are many good ways to make wireless work
such that you can be friendly to your neighbors while protecting your
assets.

I use a very simple all-platforms bulletproof "security protocol"
Jack. I don't put anything of a sensitive nature on a hard drive in a
computer which is networked, particulary when the network includes the
Internet, *nothing*. Net result is that my sensitive info can't
possibly get hacked and I don't have to diddle with any contorted
encryption and firewall sorts of pushups. I could care less if this
computer gets hacked, there's nothing in it which is of any pecuniary
or "intelligence" value at all to anybody else. What do I care if
somebody taps into my antenna modeling files, e-mail to N2EY or my
..jpegs of family and such which are in this box?!

Of course in the process I'm giving up a lot of current-tech
conveniences like online banking, online shopping and others. But
that's OK where I come from, my telephone still works and I still dial
around to place orders with the plastic, the banks are still issuing
statements, the post office still sells stamps, yadda, yadda. I have
yet to run into a transaction or an instance of passing out any other
type of sensitive info which was stymied by doing it offline.

Depends on the tradeoffs you make between security and convenience,
I've taken the easy way out of the whole endless computer security
swamp.

That's with antique satellites, not with the monster birds being
tossed up these days each of which which has orders of magnitude more
capacity than the TV repeaters.

When the satellite repeats a channel, it doesn't matter how many

people watch

Welp, I read recently that several new satellite ISPs have jumped into
that biz so common sense indicates that they have to have unused
bandwidth available in copious supply or they wouldn't have opened
shop. Fact is that the demand for sattelite access is very
cost-limited which automatically keeps the need for bandwidth down to
manageable levels. Sattelite comms will continue to grow in markets
where the users are 'way out in the boonies where cables will never go
and they don't have any options and there are plenty of those. Then
comes the huge and growing market for sattelite mobile comms. And the
consumer market populated by folk who just like working the birds.

It appears to me that in the limit and ignoring some obvious realities
the Wi-fi vs. Satellite market competition won't be a competition. By
their very natures Wi-fi or some evloutionary form of Wi-fi will grab
the big pieces of the light-duty consumer and business travel markets
and the sattelites will continue to carry the heavy duty business
mobile and remote access comms.

And all this with the monster volume of *really* broadband military
sattelite comms sharing the RF spectrum with the commercials.

Compare that to what is
available in a single fiber. Also remember that once the duct is in
place, pulling another fiber isn't that expensive, and that new
technologies permit more bandwidth in existing fibers.

Many people in this country live twenty and more miles from anything
even vaguely resembling a cable. Wi-fi is never gonna reach them.

Ducts that go
across the country, etc. Satellites can't create another RF spectrum.


What's a "duct" anyway? How many of those are running all over North
Dakota and Idaho??

It is interesting that your primary concern is to keep your
information secure -- that is indeed a very valid concern. The
approach you describe is the one that was followed at the defense
contractor where I started my career. It works very well for many
many cases and is "the right way" to handle most kinds of classified
information. However, there is a concern which isn't addressed by
your system, which is being a good Internet citizen and preventing
your computer from being used for Evil. You could care less if the
machine gets hacked, but if it gets hacked and used as an open proxy
for delivering spam or as part of a distributed denial of service
attack, your negligence leads directly to the economic losses of
others. That's something worth considering.

Brian Of course in the process I'm giving up a lot of current-tech
Brian conveniences like online banking, online shopping and

In some ways it's harder to do business offline these days, but just
as you can still use a pulse telephone without Touch-Tone, you can
still use the phone instead of the Internet.

Brian Depends on the tradeoffs you make between security and
Brian convenience, I've taken the easy way out of the whole endless

That is indeed one approach, and other than the blind spot I described
above, it's a perfectly reasonable and consistent approach. You can
still send all your Internet traffic over AX.25[1] and I can't, which
is also a plus for you. But I've got a versatile tool, a profitable
source of income, an engaging hobby, and a space heater all in one,
and that doesn't completely suck.

Quite a few are, Steve. A lot are also that integration between the
browser, mailreader and system that was supposed to open up a new world
of computing ease for us.

And I am with you, Brian...If I need to do something that bad, I will make

My suggestions for computer security a

1. Buy a Mac

If you can't buy a Mac:

1. Zonealarm Pro (avoid version 5 - if you have to register it with
version 5 do it, then find the previous version)

2. Proxomitron (or some other proxy hardware or software)

3. Don't use Internet Explorer at all - ever.

4. Never ever ever use Outlook or Outlook Express.

5. Nortons of course.

6. Adaware don't hurt.


I have to do all that stuff for my home computer (a PC) but all I have
to do for my work computer - the Mac - is turn it on, download the
updates from Apple around once a month. Hundreds of hours saved per year.
