Re: No, up to 212 MHz
That seems pretty unlikely - the power levels involved are very low - they have to be to allow this stuff to work without the crosstalk from one circuit killing every other service running on the cable. I suspect the very deliberate propagation characteristics of airborne / land to air radio services might also protect against interference.
Re: While I was rummaging through a box...
There are companies selling a modern board that pretends to be a disk drive to your old computer and uses an SD card for actual storage. It's a clever solution - you don't need to mangle your old machine, you don't need to battle with analogue audio signals and you control it all using whatever user interface the manufacturer actually intended.
I don't believe it's compulsory to read them and I'm pretty sure other articles have continued to be produced during recent weeks.
Re: How the fcuk...
"going to garner 81% of the worldwide market share within a couple of years (Android), or go with the one that's going to be stuck on 3.6% market share (Win)."
You're mistaking O/S with manufacturer.
I've bought a Lumia, so has my wife. They feel like a distinct upgrade from Android and are far better value. I don't believe we're alone in this. It's been a pleasure to leave behind the tat-filled malware bazaar that is the Play Store - like Poundland with pickpockets.
What possible incentive would there be for a manufacturer to take on an additional O/S that runs the same apps as Android, when they already have Android?
How does that work?
You can't install any OS on any hardware today - the two being somewhat inextricably linked. That's as true for a desktop or laptop computer as it is for a phone or tablet.
Show me AROS running natively on a Mac and I might change my mind...
"Personally I think the first company that brings out a device with a keyboard like the BB of old will make a killing, regardless of OS."
There are a wide range of such phones on the market right now, this second. Nokia alone sell 4.
Re: Forgot editing
A strowger final selector has 100 selectable outlets (as opposed to a group selector which only has 10 selectable levels, horizontal rotation stopping at the first free outlet).
But if you're going to cheat and do it electrically there are easier ways and you might as well use your strowger kit to drive nixie tubes.
A praxinoscope with 40 slots of different height, each one making up a row of 80 pixels. The display is monochrome and each pixel is either white or black, achieved by a shutter being raised or not. As the drum rotates all the pixels in the slot are knocked down to display white when in a non-visible position and then a series of 80 punch pins that are 'scanning' the display activate the pixel to black (or not) by their position.
The whole thing is controlled by a series of gears to keep it in sync. The refresh rate is as fast as you can make the thing work reliably - the drum will need to rotate to at least 50RPM I think to make the illusion work properly but it's probably only realistic to refresh one or two rows per revolution.
If I could upload a picture I could sketch how this thing works - try this though; Imagine a clock face. At 12 is the aperture through which the illusion is viewed. The drum spins clockwise. At 2 is a bar that knock all the pixels in a given row back to white. At 5 is the pin mechanism to set the chosen pixels to black. The bar and mechanism are attached to a stepping mechanism that starts at row 1 and increments once with each revolution - returning to the top after row 40.
It's sort of time appropriate - the praxinoscope (using still photos) was invented in the 1870's.
Re: The last ever 'proper' Nok?

Re: seems to raise a lot more questions than it answers
The problem with that being that it's hard to provision capacity for a rapid rise and fall in users of a given cell as a crowded train passes through it's coverage area without also disrupting the service of people working or living next to that same railway line, also using that same cell. It's cheaper and easier to build an overlay than it is to accommodate that traffic on the main network.
In urban areas the cell handover signalling for hundreds of users passing through multiple small cells at high speed, while trying to use the data connections, is something of an engineering problem.
Re: Sounds crazy and backwards
Comms and signalling to trains and staff uses GSM-R, a specialised variant of GSM. It's not appropriate to try and mix public traffic on that network and there's no provision for the kinds of bandwidth being talked about.
The rails can't be used as they are already carrying other, infrastructure level signalling information.
Without significant changes to the way mobiles pick a network connection cellular data's not a good option - which leaves WiFi. Hand-off between access points for a moving WiFi terminal device isn't great and so the remaining, easier technical option is APs on the train communicating with a regularly spaced set of wireless concentration and backhaul nodes, probably bolted to the frames for the overhead electrical wiring.

Re: Moto X it is then!
Good grief, what is it with people wanting to run one company's OS or kit on another company's OS or kit?
I'd quite like to play Commodore 64 games on my Oric-1, but it's not going to happen. BB's environment and inherent security relies on the vertical integration of hardware, OS, servers and network.
If one of iOS, Android or Windows Phone (or a feature phone platform) doesn't do it for you, it might be your requirements that are wrong.
Re: Am I the only one...
For the price of an i7 laptop I could buy a typewriter, some paper notebooks, a full set of felt-tip pens and a portable DVD player - but it kind of misses the point.
Re: Just Imagine
Meego ended up such a tangled mess it needed starting again from scratch to be a viable long-term OS. that's exactly what Nokia didn't have the time or money to do. Their strength was always in hardware and their own apps - Android would have left them just another 'me too' with little to differentiate them - who buys an Android phone for the manufacturer's apps? This game's not over by a long shot.
Re: Am I the only one...
The sensor is 2/3" - the same as most compact cameras.
I think you're missing just how deeply zoomed some of those images are.
It's interesting how in the space of maybe three months the comments on Lumia articles have gone from "no-one will ever buy one" to "I've just ordered one", "my 720 does this", "my 620 does that". I'm seeing a fair few in the wild, and both me and my wife have bought 820s - which means we can do the party trick of opening a photo on one phone and sending it to the other just by touching the cases together.
I bought an 820 - and like you found myself seriously impressed at how well it works after owning Android. The hardware is good, certainly, but the OS is really very, very good. The simplicity and integration between apps - especially the Nokia developed ones - is exactly how a phone should be.
That will be because of the price differential. Plastic is a dreadful material to use, if you price your phone at a point higher than the mean annual income of the world's population.
Re: More and more frustration...
Why? I've switched from Android to a Lumia and it's really rather good. WP8 is excellent.
Re: Only one problem
We've got an array of devices on our house - iPad, Windows laptops and desktops, android phones and tablets and even a desktop running Edubuntu. I've got a WP8 Lumia - it's without doubt the best phone I've ever owned. When I switched from an Andoid mobile to my Lumia I felt like breathing a sigh of relief. That people think Android is a mature, reliable operating system ready for the big time amazes me. Don't get me started on the Play store rammed to the rafters with buggy, ad-crammed nonsense. It's the digital equivalent of poundland.
Re: Megapixels are not everything
It has the same size image sensor as most compact cameras - 2/3"
Re: Someone has to pay
I think the distinction with services like BT's Vision service is that they're not Internet. They use a portion of the ISP provided last mile to deliver content hosted privately. Conceptually it's the same as watching a film hosted on a NAS in your home on your Smart TV.
Just because something is using an IP network doesn't mean it's the public Internet - and it's a distinction that I think some of the net neutrality debates completely miss. If net neutrality laws are passed I think ISPs will shrug their shoulders and set about building private overlay IP networks to deliver content from their commercial partners. Akamai have built a very successful business doing almost exactly that.
Re: How would this even work?
The ISP and the content provider agree to provide a private connection between themselves that bypasses the public Internet and delivers that content at a guaranteed rate close to the consumption point. The content provider could even pay to put servers hosting content in exchanges/central offices.
The ISP hasn't limited or restricted the competitor's service, it's just made sure that its preferred content provider's packets have a much better chance of being delivered in a timely fashion.
It's common in Europe with ISP's video on demand services. Delivery is guaranteed because the service isn't being provided over the public Internet, it's being provided from a server in the telephone exchange hosting the end user and then delivered using a portion of the last mile access reserved for such content at the time the user asks to watch it. The important and relevant point is that it's not the public Internet and so any net neutrality rule would be moot. A content delivery network engineered end to end to ensure effective delivery beats best efforts public Internet every time.
Re: On the other hand...@Terry Barnes
Well the problem then would be that you'd never be able to go faster than that 1/50th. Today you get to use your connection at full speed all the way to the peering point if the network isn't congested. Insist on getting exactly your 1/50th and you've essentially gone back to a couple of hundred kilobits max.
Re: illegal for anyone to pay extra for a decent Netflix connection
Isn't that the problem though - expectations that aren't accurate? You're not buying a dedicated connection to the Internet, you're buying a last mile at a headline speed and then a share of some backhaul to a peering point. If you're consistently using more than your fair share in a way that is detrimental to the people you are sharing with, your ISP takes steps to redress that.
Maybe ISPs should be more upfront about contention ratios and the like, but there's a chance they'd just confuse people. You can buy uncontended high speed bandwidth from end-to-end but the cost is dramatically more than buyers of consumer broadband want to pay. It's cheap *because* you share it.
Re: Bus Lane? Try Ford Lane.
It's not that its prioritised as such - it's more fundamental than that.
A separate IP network, that isn't the public internet, delivers the special content to the edge of the network. Video on demand is served from a point as close as possible to the last mile - that's how businesses like Akamai make their money and it's how VoD services provided by ISPs work.
Net neutrality laws won't and can't change that. The traffic isn't Internet traffic, so how will a law applying to Internet traffic even touch it? Your ISP is reserving part of your last mile bandwidth to deliver non-public Internet IP traffic. If the law is framed to try and extend beyond the strict definition of the public Internet then MPLS becomes illegal and corporate WANs around the globe stop working.
I'd guess as well that ISPs *could* give all traffic equal priority but perhaps could neglect to provide enough bandwidth to the peering point that they know certain traffic comes from.
My view is that this stuff is too complicated and technical for any poorly-framed law to actually have the intended effect. The market should decide.
Re: On the other hand...
You're only really paying for your last mile speed. If you want guaranteed throughput all the way to a peering point you can have it, but it will cost you thousands. Consumer broadband is built down to a price - and that will be true all the time the vast majority of people buy broadband based on what's cheapest.
Contention of 50:1 means that things can slow down at busy periods - but it also means that the expensive part of the connection costs you only a 50th of what it otherwise would.
I'd go further and say that the Linux brand on a consumer device is the kiss of death. Normals are terrified of those 5 letters. There is space for niche products as Vertu have shown, but the carriers won't even think of lifting a finger to help - and why would they, what possible benefit is there in it for them?

Re: Hang on, what?
I bought a Lumia 820 recently - it's undoubtedly the best phone I've ever had.
I even like Windows Phone - it remembers that the device is primarily a phone. Tiles look more modern than the icons on other platforms, in my opinion, and seem better suited to touch operation.
For the price of the phone in the review, a valid comparison is much higher up the model range than the 520.
How does this contravene the DPA? You can't give informed consent because there's no way the data that has been collected could be used to identify an individual. It's hard to throw people in jail when they've broken no laws.
Re: What has it got in its pocketsess?
"So an MAC doesn't sound so different to a phone number."
The point being I think that it's trivial to engineer a reverse search to find an individual from a telephone number. Depending on how and why that's done, that can be legal or illegal.
With a MAC address - much harder. You'd need the co-operation of the mobile operators and they won't co-operate because they're complying with the DPA.
A mobile's telephone number is only used by the network you are taking service from and its transmission to that network is encrypted. A MAC address is transmitted in the clear to any device that asks to see it.
I can't see a way that the MAC address of a mobile phone could be used, in isolation, as a piece of useful data about an identifiable individual. Now, if the bins had cameras in them.....
Re: Rah Rah Rah
I'm struggling to see that they've broken any laws so the ICO can't do very much. The DPA doesn't apply as capturing MAC addresses doesn't let you identify individuals (though trying to match those MAC addresses with a person list would be illegal). RIPA might apply, but again - there's no information about individuals here.
Re: Got as far as...
Wind your neck in! It's not dishonest, it's enbtirely and demonstrably true.
The sentence you refer to makes no reference as to the efficacy of those inputs, only that it is able to incorporate them. How is a factually correct statement dishonest?
Re: Packet Switching
Extra large packets are no good for real-time applications though - all you do would do with voice is increase the propagation delay while you wait for enough bits to fill your new super sized packet.
Re: Battery drain
It's the processing required to use 4G that drains your battery. The radio has to receive a bitstream, decode it and then extract the bits relevant to you, separating them into streams for the processes running on your phone that need to use them. The same happens in reverse too.
Or put another way - the transceiver doesn't use much power, the processor controlling the transceiver needs plenty.
Packet switching is only more efficient where the traffic is random, or as good as.
If you find that you have lots of traffic heading for the same destination, or that is part of a sliced up continuous datastream (as in a telephone call or streaming video for example) then circuit switching becomes more efficient. This is because the packet overhead consumes a significant amount of the available bandwidth resource. In a TDM network that destination intention needs only be signalled once and then the entirety of the channel bandwidth can then be used for payload. In a TDM network a G.711 call takes 64Kbits - the same call presented as an RTP stream over IP consumes 96Kbits.
My belief is that the next 'step' in networking will be to introduce a hybrid model where both packet and circuit switching are used according to the type, urgency and distribution of traffic being handled by network nodes. Before IP won the networking wars the logical next step looked to be the B-ISDN standard. Circuit switching at a much higher bandwidth (probably 2Mbps) than the existing 64Kbits narrowband ISDN.
Both networking models have advantages and disadvantages - and historically we've tended to swap between packet and circuit models, from the days of the first postal systems. We've reached a point where it's affordable and feasible to do both using the same endpoint.

Re: 7.4 million phones = 5 days for Android

Android is an operating system. Nokia is a manufacturer. Do you see the difference?
Re: the market continues to reject WP
Don't extrapolate from your views to presume everyone else feels the same.
I don't get on with iOs. we've got four Android devices in the house and none of them work entirely properly.
When my wife and I bought new phones last month we *chose* Windows Phone deliberately. I like it - it works properly, it's easy to use and it's affordable. My Lumia 820 seems easily as capable as an iPhone and more capable than the Samsung Android it replaced.
Re: My left testicle...
"That said, a Nokia with Android would be a million times more marketable than the Windows Phone crap they are trying to offload onto unsuspecting consumers right now."
They sold 7m Lumia last quarter, let's call it 25M for the full year.
You're saying that if they dumped Windows and used Android that they'd then sell 25 BILLION phones in a year?
I suspect that's not true because if it were, they'd be doing it.
Re: your arrogance remarkable .
"without windows we wouldn't even here to talk about this phone"
I'm sorry, what? I actually own a Lumia but I can't decipher your comment.
The history of personal computing is not all about Windows. Other operating systems have come and gone and if Windows hadn't have been so successful another one would have. It's not true to say none of us would be commenting without Windows, it would be true to say that we would be commenting on OS/2 or Amiga OS or something Appley or something from DR or NeXT or BeOS or a hundred other choices. Hell, we could even be commenting away on an Oric Ionos running a Tangerine GUI.

"Monopoly abuser Microsoft with its straight jacket OS with the garishly colored tiles is just not an option."
You're not concerned about Android owner Google's monopoly on search then?
You can change the colour of the tiles and the size of them. Can you do that with icons on Android or iOS?
I bought a Lumia last week - it's bloody great. The designers remembered that it's meant to be a phone first and a 'device' second. Windows Phone seems perfectly good - far more polished than Android. We've got 4 Android devices in this house and not one of them works 100% properly.
I'm also seeing a lot of Lumias being fiddled with on trains and in pubs - there's a vocal group of commentators on here who despise them, the public seem to think otherwise.
Re: Presumably independent action would be legal...
You only pay tax on profit usually. The 10% fine is on global turnover. Given the size of the margins in the telecoms world a fine of that size would turn a healthy profit into a stinking loss and probably result in thousands of job losses.

We, as voters, can't complain that no-one in government has any idea of how to run a business and then put in place measures to *ensure* that that's the case.
