Interesting

Thats faster than taking than opening the back of the N900 taking out the sim and sticking it in my PC :D

This is a great technology - imagine how easy it would become to buy content from brick-mortar stores direct to your mobile device - something the brick-mortar music stores need (along with competitive pricing) to make them stay relevant any more ..... but I still doubt that the music industry will ever embrace any such technology - they still want to sell CDs

dont give that biased engadget site traffic send people to look at official site instead http://conversations.nokia.com/2010/...nsfer-concept/

Re: Nokia Demos new transfer tech
 

Interesting that the N900 seems possible to recive that amount of data, future Fw upgrade or some mystery hardware already inside?

Re: Nokia Demos new transfer tech
 

Didnt mean to give engadget extra traffic - I rarely hit the site anymore, if i had known the other had it already I would have linked to that

Re: Nokia Demos new transfer tech
 

The way this was demonstrated there was no data-flow control on the N900 side of the transaction. So if it works like this in general then it means that anyone who gets close enough could just dump whatever they want into your N900. Not nice.

So the technology would need something like what's used for BlueTooth, i.e. either pairing in advance (unlikely for the kind of buy-from-store service demonstrated in the video), or a pop-up & accept on the receiver (N900) level. In other words, never as simple as demonstrated in the video.

Re: Nokia Demos new transfer tech
 

I think that they have allready done the pairing before they shot the video.

Re: Nokia Demos new transfer tech
 

I think it is ultra short range. It touches to that nokia box underneath, which acts sort of like pairing. Nobody can dump data to your device unless you virtually touch it on the transmitter. It just saves the hassle of pluging in the usb cable. (and the danger of them stealing your data)

thats more than 100MB/sec .. but to where? eMMC or the internal NAND in that speed.. ?

Re: Nokia Demos new transfer tech
 

one album in 10s -> about 100MB (256kbps) in 10s = about 10MB/s

ohhh we need this in our stores in the uk, now, we need it now :)

Re: Nokia Demos new transfer tech
 

To pair would be highly inconvenient and unlikely for the kind of pay-service they demonstrated.

The article refers to RFID technology and 10cm range. As far as RFID is concerned it's been demonstrated again and again that it's totally feasible to access devices from a much larger distance, with the right equipment.

So this doesn't sound particularly safe. It's difficult to combine convenience and security.

I don't think this is a big mystery wireless technology.. I assume what they did is tweaking the 802.11 MAC-layer, so it may actually use the same hardware as in the N900. The reasons for my assumption are the following:

a) They almost certainly use the 2.4GHz band (same as 2.4GHz 802.11 and bluetooth), anything else doesn't make sense if you want to sell your technology worldwide.

b) The 802.11 MAC layer has quite a bit of overhead from ACK messages etc. For this application the sender and transmitter are very close, so you have a high SNR and low bit error rate, i.e., few lost packets and therefore few retransmissions. Being close also allows you to tweak the timeouts in the 802.11 MAC layer (they are designed for a range of 100m or something). They could also make more fundamental changes, such as adding some kind of streaming transfer mode, which would further increase the throughput for applications like the one shown.

These are just my 2 cents.. as usual Engadget doesn't really have a clue about the technology they are writing about.

Re: Nokia Demos new transfer tech
 

It's right there in the text below the video:
"this new radio tech forms a short-range connection between the writer and the device, and doesn’t use any other radio networks – the writer is immediately paired with and recognizes your handset"

In other words as pointed out by qwazix it's just an uber-short range wireless solution; the lack of range means "any signal can be trusted" as you'd have to be close enough to the thing to know that you're communicating with it (theory goes... reality could be a different story). I'm guessing there's also in the end going to be some interactivity on your phone/device that says "enable/confirm transfer"... I don't see that being a huge hinderance or anything considering your device has to be out sitting on the "Box" anyways... just hit OK on your device and let things go... that way if somebody tries to carry one of these boxes around in their pockets and get too close/give you a hug or something to try and load your device with junk nothing would happen since there wouldn't be a confirmation...

I think the most interesting fact about that video is, that it was filmed somewhere between May - July 2009, since there's no snow outside.

We've had quite a good winter this year in Finland, and the street is sunny and clear outside.

So they had the N900 + this wonder tech in there already 6 months ago! :)

EDIT: That was filmed in the Helsinki Flagship store.

Bolded part should be November.

Re: Nokia Demos new transfer tech
 

I think it's fair to give credit where it's due.

Engadget reaches far more audience than conversations.nokia.com, and having them 'broadcast' the news is beneficial to Nokia.

@Bratag: thanks for the head's up.

Re: Nokia Demos new transfer tech
 

I think they managed to make the hardware Bluetooth-3-aware. That's all. And it's good news for N900 owners.
