You DO realize that the south pole station is built on ICE right? It's about 9,000 feet to bedrock there and the whole station moves about 10M/year (north of course.)
Ummm... You want to build towers out in the middle of nowhere tens and hundreds of miles away and use microwaves to send usable amounts of power between them?
I beg to differ. We have highly directional antennas being used in urban areas now and cell sizes that are getting pretty small around congested areas. So we are already doing what you say will fix this. Putting in more cell towers and antennas does help, but in urban areas where 5G would likely be put first is already subdivided pretty small.
But when you up the data rates, you have to increase the bandwidth and/or power. Physics demands it. So if you are already maxing out your licensed spectrum doing 4G (and they are) you will need more spectrum. Then if you consider the fact that 4G devices will need to be serviced too while 5G is rolled out, you will see that it's not going to work to do what you say. (Not to mention that RF exposure safety limits may start being a problem here too..)
For ground based devices that don't move, fiber is cheaper and faster.
Trust me on this, 5G is largely useless if the only point is bandwidth... Not saying they won't try to sell it, but the bandwidth required for 10X 4G will put you into spectrum you simply cannot afford in mobile devices due to power budgets and semiconductor costs.
So it's really about the spectrum space being unavailable and what they can get being expensive to use.
Another thought. How low does a plane need to fly to "drop off the radar"?
First, Civilian radar depends on transponders, a small transmitted signal from the aircraft that is triggered by the Radar signal. This transponder responds with a "squawk code" (a 4 digit number assigned by ATC) along with some other basic information like altitude. Transponders make it unnecessary to get a "primary" return (i.e. they don't have to get the actual radar signal return) for the aircraft to show up. In fact, most civilian radar installations run with primary returns filtered out because they create visual noise for controllers, because weather and other noise shows up.
Second, the aircraft in question was at the far reaches of radar coverage. This tells me that a primary return was unlikely. In fact, the radar coverage for this aircraft was expected to end right about where it did. I"m told that radar coverage did not start back up for the next controller for a few min of flying time so a short time out of coverage was expected. They will pull the tapes and review for any primary returns, but I'm guessing this has already been done an it provided little information.
So, this tells me that something happened to the aircraft during the short time it was outside of coverage. What ever it was, it must have disrupted the flight controls and likely their communications ability, but it seems that the aircraft stayed largely in one piece, at least until it impacts the surface. If it was generally in one piece with say the vertical stabilizer disabled it could have flown a LONG way from the last position report.
It did NOT break up at altitude. Something rendered the aircraft uncontrollable. A loss of hydraulic pressure or power does this for a 777. Decompression at 35,000 feet can do significant damage to an aircraft's systems, plus it can incapacitate the flight crew in less than 10 seconds. Decompression can do this, without causing the aircraft to come apart in the air. Metal fatigue, fuel tank explosion, small explosive device, uncontained engine failure are all possible things that can cause decompression and all of these have happened before.
My guess is that they will find the aircraft tens even hundreds of miles away from the last known position, largely in one piece under water. The longer this takes, the further away from where it was last seen it will likely be. This is because they have found nothing yet. Much of an aircraft floats, so it sank in one major chunk with out spreading debris too far. This is not totally inconsistent with past aircraft crashes. KAL 007 flew nearly 20 min in a slow descending circle after being shot down. They will find it in a day or two.
So, what do I need a 300GB, when I can go to Fry's and get 4TB drive and just plug it in?
And when you run out of space, you just buy another unit and plug it in? Why have a unit always on just for an archive? Sucking up power just for a day that you might need the archive.
Most drives can easily spin down when not in use. Then there is a small delay as the platters spin back up but the power consumed when a drive is not spinning is quite minimal.
Because, you know, we never ever actually create new things that are larger and need more bandwidth to transfer. re: standard definition vs high definition. If the market creates a capability, there will be someone or something that will seek to fill that capability.
You can stream HD video now over 4G, how much more bandwidth can you sell and for what?
Latency improvements might be a good thing, but by my reading 5G is targeting 100X the bandwidth of 4G. Even if they manage 10X, I'm here to tell you that they are going to have to find spectrum space for this. Physics require it. The only spectrum available that makes sense is higher frequencies than where we are now with cell phones. But the reason we don't use this spectrum now is because solid state devices that work at these frequencies are incredibly difficult to engineer (and thus produce) and suffer from huge power requirements.
Mobile devices just *don't* have that much of a need for more bandwidth beyond an HD video stream. It's a hand held device running on battery power. What we need is low power consumption and enough bandwidth to do what you need. I don't see 5G's targets making much progress in the practical world.
I suppose there is always a place for more bandwidth, but the limiting factor is going to be spectrum space here. 5G is most likely going to increase bandwidth performance, but at what cost? Using 4G you can stream HD video now, what more do we actually need? For mobile devices, I'm not so sure there is much more necessary.
As always, the issue really is spectrum space. Where will it come from *this* time? Cell spectrum is generally well used (at least in urban areas) so there will be a huge push to find something else. Problem is that all the available spectrum is way up there, where solid state devices start having serious design issues and the power required is huge. You thought your 4G phone battery died quick...
Research is great, I'm just not thinking there is much practical that will come of this.
They already said they want any mobile OS that doesn't allow the government to shutdown and make worthless any device that a protester owns. They know they constant huge occupy protests are just going to get larger and more powerful so they keep demanding to be able to brick devices own by the freedom fighters. Expect the contributors to this Firefox scheme to be put in prison for challenging the Republicans this way.
Wasn't this a Democrat suggested bill? Why are you blaming the Republicans? H.R. 4065 right?
You approach closer and close to the "absolute truth", but never get there, and every pi microns there is an e chance that there will be a step function and the whole convergence has to start again.
Um... Your argument is irrational... Or, at very least based on irrational numbers...
Fermilab struggles to find enough funds to maintain their conference Audio Visual equipment and has discontinued providing video projectors for lectures to save money. Facing difficult economic conditions and funding shortages has forced a re-prioritization of how money is spent on technology.
"Others are claiming this is about not wanting to use Power Point," said one A/V technician "but I can assure you it is about saving money. We are simply not replacing any projector lamps and as existing equipment stops working we are taking down the projection screens and uncovering the chalk boards they cover."
Manufacturer can do that if they want. Apparently LG and ATT elected not to do so on my phone. I'm personally OK with it locked down as there is really very little I want that requires root. (Only one thing comes to mind and it was decidedly optional). I just want the phone to work, and so far it serves me well without root.
But that is me. Your mileage and desire for root may be different.
So does this mean we can sue this vendor for damage their tool causes? Hope so.
You knew it was coming (if not already here); Android virus infections, or more likely malware is the thing. But now that they have Android locked down pretty well, shouldn't be a huge issue. These days, just rooting your Android device is not as simple as running some root kit. You have to actually flash new firmware on my 2 year old phone to root it now.
But, really, what's the big deal? Just installing apps is a crap shoot already. Most do things with your personal information that would have desktop users up in arms if it got out. On smartphones they just put it in the EULA and it's a free for all. You READ those things right? Yea, me too.
I have to remind you that this was about a location database developed though the scanning of car license plates as they move around on public streets. Companies collect and sell this information, mainly to people trying to get cars back for lean holders when their customers have failed to make payments. And the question is about what could happen if there are errors in this location data.
How about if you lose your job because you can't get to work because your car was erroneously towed.
Um, how/why would a database of scanned in license plates get *your* car towed when it shouldn't be? A Repo man isn't going to tow something unless he KNOWS it's the car he wants by checking the Make/Model, Color, Plate and VIN. How does inaccurate information in the location database get the wrong car towed? Hint: It won't. Your car might be repossessed in error, but this is NOT the fault of the location database, the Repo man or the lean holder made the mistake. Strike one. Next!
How about if you get frostbite because it's 7 degrees outside with a wind chill factor of -18 and you cannot drive home because your car is gone.
Same issue as the above.... Repo guys are going to check the license plate number and VIN before they hook up and tow. This information (plate and VIN) comes from the lean holder NOT the location database.... Strike two... NEXT!
How about if your car is damaged during the towing process because the tow truck driver, who took your car when he shouldn't, is an idiot.
If your car is towed in error, sue, you will recover any costs. If it's damaged while being towed, sue. They have insurance for this. But, again, this is NOT the fault of the location database gleaned from scanning license plates on public streets. The repo folks are going to check the car's description, plate and VIN (likely in that order) to make sure they match the lean holder information. Towing the wrong car is not something they want to do because it could be considered a felony. Strike three... You are OUT.
I'm pretty sure the number of issued BTC is just an agreed upon number that could be easily expanded. It would take a revision of the protocol to allow more, but as I understand this, we are talking about changing a defined value and worst case would be a recompile of everybody's software.
Ahh.. You have hit on the long term issue I had with BTC. I've read stories where people have lost their coins which will take them out of circulation, and the problem you talk about is further reason for coins to be lost.
One could argue that they would just issue new currency to miners like they do now, but that's a problem too.
But I will wager that in the ODD instance where such data is used there will be more evidence required to even bring a charge. Just saying that some license plate was scanned at location X at the time of the crime won't be enough. Especially if that data was collected by a company for other reasons than solving a crime.
The price of the lawyers not withstanding, I would contend that there where *other* causes in your hypothetical that drew the criminal charge, not just an error in the license plate data. But you are describing a situation where there is more than just bad information in a database, but there would have to be additional evidence. How's this the database's fault?
Not to mention that the chances of there being bad information that leads to the wrong person being charged is pretty slim. DA's don't take cases unless they think there is a chance of getting a conviction. So is it possible? Yea, hypothetically, but extremely unlikely in real life. If it happens to you, I suggest you sue the company who provided the bad information in civil court to collect your legal fees. If their data was responsible, I'll bet you can collect for your legal fees and possibly a bit for mental anguish too.
I'm asking for a hypothetical situation where license plate scanning errors could harm somebody. I don't see any situations where this would be true so your claim that it *could* is not washing with me. Come on, invent something if it is so obvious that I'm wrong.
