From what I've seen of both, whether voice can "make it through" as opposed to data, depends on which data protocols and equipment
are being used. I don't know enough about what DSC
is using to guess at that one. The good thing about DSC
is that you don't have to try comprehending bad phonetics, hideous accents, and plain old sloppy speakers with marbles in their mouths.
Satlink and Rebel Heart would be irrelevant to this. "Your" IP address could be assigned to you by a government
administrator, much like a Soc. Sec. number. In which case, it could be free and permanent and not subject to commercial
interruption. Or of course, you could rent or lease
a block of them. All kinds of options are open--not just the "I've got a sleezy carrier who doesn't know how to communicate" problem that RH supposedly had.
If GE or Amana can figure out how to give my refrigerator
a permanent IP address, then Icom
or SH can do the same for my marine radio
. And then I just have to contact a registry and register, or transfer, that IP address to my name. Same process that is used to transfer EPIRB ownership
today, you go online, send an email
, no money
changes hands. (At least not in the US.)
If I change my phone
number from an AT&T landline, to a Verizon cell, to a Sprint cell, to a Podunk VOIP company...somehow, it all just happens. The number stays with me and the cost is government
capped, and CAN be zero if the carrier is not a pig. Some carriers take the full 30 days that they are allowed to take, in order to inconvenience the change. Other carriers manage to do it in 48 hours.
As I said, it is time the ITU took a look at the future. This stuff CAN all be integrated, and the costs of doing so can be less than the current
costs of operating redundant and disconnected multiple systems with constant paperwork filing and updating.
Simple and quick and painless? No, good planning rarely ever is.
But consider: Give everyone a new phone
number every time they move? Or just transition to the cellular system, and let the routers figure out where to ring the phone? That expensive new system has actually chopped prices way way down, not to mention, making life quicker and simpler for everyone. (Well, simpler until the carriers start playing games.(G)
You raise good points! I have seen both of the two top carriers "lose" SMS messages for 6-24 hours. This is not inherent to the system, however, it is the result of cheap
corporations. Usually the excuse is that "it was on a server that went down" and that's really not an excuse, it means "we were too cheap
to have redundant servers or acknowledgement protocols". In fact the old DARPA Internet
design was originally based on every server passing a message to the next most likely server--and then if it did not get a success ack, it would try again on another route
until the message WAS successfully passed on.
In that way the internet
is exactly like high seas radio
. You can call a vessel for days, but there's no assurance it has heard you. Well, the net provides for taking actions based on whether it does/not get an ACK from the destination
. It also provides (if you use the master routing that the cellular carriers do) for constantly knowing "Where is this device? Is it active? Can I reach it?" and it would be able to say "Yeah, Davy Jones isn't answering his VHF
, let's see if the HF or the cell or the satphone is active. Oh, heck, let's ring them all at once...or sequentially in a hunt group."
Heck, there were Telco's doing that 20 years ago, sequentially ringing all of your numbers, home, work, mistress, second home...until something picked up. No need for the human to dial around trying to find you, that's donkey work.
And again, government regulation and corporate greed plays a big role in reliability
. You've probably heard one cellco advertising "the most reliable in the business". What you have never heard, is that none of them ever generates a busy signal--they divert calls to voice mail, and they may not send the silent "message waiting" signal for hours. Ooops.
Wilma, the cellcos were up and running for 24 hours after the landline companies were flooded out. Then things changed, as the landline companies were required to have 3-day battery
backup power, but the cellcos were not required to have backup power--and as a result they went down and stayed down. Part of the aftermath is that the FCC "encouraged" them to play nicer now, if any carrier has any fuel
for any backup generator
in a given area, they WILL service
towers that belong to their competition, in order to keep the whole system up.
Big changes, and careful regulations
can make them standards.
It certainly isn't less reliable than "let's see if he's in cell range. Or maybe VHF
. Does he have HF-DSC? Oh, well how about the satphone, or at least, a text on the InReach?" By the time you can find all the numbers and turn on all the equipment
...good routing can have them all ringing, or at least tell you "He's out of range."
You realize, if refrigerators and now, commercial
aircraft (thank you, Malaysia) and even CARS are getting hooked into the web....what's the excuse for not hooking up boats? It isn't perfect
? So? It can still be way better than it is.
