You are probably wrong. There is a certain gentleman who is a genius when it comes to radio, who started a company. Ericsson bought that company for approximately $40 million under the circumstances he worked for them for a few years. Now that time is over, and he has started *another* company. This was a few years ago, and by then he had an analogue telephone smaller than the smallest GSM-phone. More interesting than that was that it broadcasted using like 0.1 watts, when GSM-phones (at least back then) used 1-3 watts. As you can understand, it consumed almost no batteries at all. Another interesting thing about it is that the BS (base station, I've gotta remember you don't work where I do (-: ) could be tens of kilometres away, because they were so advanced.
Furthermore the NMT system might get SMS-services, possbily encryption and other features that up to now have been reserved for GSM. So don't think that NMT is over!
Just a comment. The European digital standard (i.e. GSM) has had SMS-services for the past 20 years, in USA you are just getting it. And of course, you can't stick to standards either. It's 160 letters, get that!:-)
" er...if you are worried about the radiation damaging you, bear in mind that the antenna is already right next to your head. "
The Point is that it isn't omnidirectional. It can only go in one direction, where *all* of the radiation goes. With todays antennas the radiation is spread out, which is at least *better* then when it goes only in one direction.
" the signal will have passed through buildings, cars, trees, and all sorts before getting to your phone. "
Yes, but that has already been accounted for, and that is what causes the bit delay problems. Still, that is not such a big 'energy stealer' as would it have to go through the hand, or for that matter the head.
The Point (here I go repeating myself) is that it wouldn't work in todays phones, neither in tomorrows phones. Perhaps in the day after tomorrow, but by then we will probably use some other kind of system for transferring the signals...
Am i just stupid, or don't you have to be connected for it to display ads. I mean, the first time you boot it, it obviously can't display any other ads than the ones that were added during manufacturing, but who would want to buy ads that will be displayed some time between 1 and 3 years from the time of the buying? Also, if I run the computer single-mode and never connect it to the Internet the ads can never be updated. Or perhaps the are confident everyone will have a permanent Internet connection by the time they release this BIOS...
Well, anyways, I'm just stupid and probably should return to work...
I talked to a friend/collegue here at work, and here is what he said:
" As is common in the US, companies sometimes make a big noise about stuff that has been known for (almost) forever. As even mentioned in the article, random and regular layouts are both tradidtional for phased array antennas, but other layouts are also used and their characteristics are known.
However there are a number of HUGE problems before you can bury such an antenna in a handset as they suggest tand the (prototype) phone shows.
1) array antennas only effectively transmit at 90 degree to the surface. If you add it some electrical tilt this can be extended to approx a 45 to (extreme) 60 degree eitehr side of that but the circuitry to do that dynamically is VERY complex.. far too big and battery hungry for a handset using todays technology. Mobiles in any case require 360 degree coverage.. you can have a handset lying down standing up, in any orientation you like relative to the RBS (base station)
2) That energy would need to go through your hand...(or your head)... not smart and you would loose MANY dB... most of the power. which removes the point
3) actually you can't build a phased array that small in any case, the article is just "science fiction" in the sense that it is theoretically possible... IF we were using very very high frequencies. But a practical problem is that you can't have the elements of the array signigicantly closer together than a wavelength, otherwise they just couple togetherand dont act independently (and the array therefore stops functioning as an array, it just works as one antenna). a 900 MHzsignal has approx a 30cm wavelenth.
So, if I don't shield it and cause interference with my mobile phone the world will end? As long as you haven't got anything very sensitive I'd say it's it's OK to "cause interference", but of course, I'm just in tenth grade and know nothing about physics...
Also, it's not like the FCC will knock on your door...

So that's that!
The computer in my living room has no case. Is that why my cheap Grundig speakers blew up when I connected them to my Onkyo sound equipment?
Automatic gears are for women who don't know how to drive, the elderly and Americans...
