That's not _necessarily_ true. Until now, sure, you needed to convince the carriers to sell your CDMA device. But, if Verizon is going to be true to their word, then all Nokia has to do is get their devices certified, and then the customer can buy them without Verizon branding them. And hopefully this will lead to Sprint and the smaller CDMA carriers following suit (MetroPCS, Cricket, etc.).

Also, "generic EDGE/HSPA unlocked device anywhere in the world" isn't trivial. There's at least 3 or 4 frequencies they have to support now. If they do it, then great. But if they only support Europe and AT&T (spit), but leave out T-MobileUSA, then I certainly wont care.

As for a WiMAX modem for current tablets, wouldn't that just create a bottleneck when transferring data from the modem to the tablet? AFAIK WiMAX is significantly faster than either Bluetooth or USB, so it would make as much sense to just stick with using an EV-DO or HSDPA phone as a modem.
I don't want to see "modem" per-se, but I would _LOVE_ to see Nokia compete with Cradlepoint. Only, instead of using an external EVDO device (Cradlepoint's devices use USB to connect to a phone or dongle), they could have 3 models that use internal radios, one CDMA/1xRTT/EVDO based, one GSM/GRPS/EDGE/UMTS/HSPA based, one WiMAX based. All would have:
  • Wifi for communicating with clients
  • RJ-45 for connecting to a WWAN or LAN (depending on situations)
  • USB client and/or OTG for config and charging
  • LOTS of battery
  • SIP server for interfacing with CDMA or GSM voice capabilities (and whatever WiMAX might have in that regard)
  • Jabber server for interfacing with SMS/MMS capabilities

This wouldn't just be a good companion product for the NIT line, other consumers could use it for their laptops (the MacBook Air doesn't have an express card slot, for example), UMPC's and MID's that don't have WWAN options (how many EEE PC users might buy one of these?).

And by having the delivery be Wifi, they can do a lot better than bluetooth and USB speeds.

I think I'd much rather see that than a version of the N810 for each WWAN, etc.

Now they promise shipping hardware in April/May and usable system for end users in June/July. In theory Nokia with all its OMAP experience and deep pockets should have less trouble in releasing OMAP3 based device than some random small startup so I'm curious when we'll see real Pandora hardware in the wild.

My apologies if this has been answered (I saw it asked): will the WIMAX edition be new hardware or can current N810 owners somehow upgrade to it given that the N810 is only a few months old? does the N810 have the hardware inside that currently is not "activated?"

Only through the same method used to upgrade other items--notebook computers, digital cameras, cellular phones, etc.--that are no longer the latest and the greatest mere months after their release: sell the old to help finance the new. Or just stay out of that money burning hamster wheel.

No. T'would make having a "WiMAX Edition" confusing if the non-WiMAX Edition also featured WiMAX, no?

Erm, magic? . . .

Seriously, if the chip isn't there, the only way to give it WiMAX is with some sort of USB or Bluetooth dongle-thing.

If that means using a WIMAX enabled device which can share the connection over bluetooth/wlan, sure, why not?
If it means a HW hack, your neighbor must have a quite advanced lab for redesigning the PCB and also access to the missing components (namely the WIMAX chip).

Really? I thought that the N8x0 had a serial port under the back cover. Nokia could make a replacement battery cover with WiMAX connecting that way. Should be able to get 115 kb/s easily.

No, it's not there. There's a lot more certification to be done with the FCC if there's a WiMAX radio in a device.

Hahaha . . . I like it. :p But, seriously, bandwidth issues aside, enabling the serial port requires using the Linux flasher tool, and it kills battery life.

The serial port is used to burn in firmware in the factory... not sure if it can support additional use.

Ok, needs flasher to enable, but you have to have flasher to update image to OS2008.25, anyway. And it's a new battery cover; it could cover a new battery. :cool: It could be the greatest thing since microSD and fixed internal memory...

Edit: Tex, it's used as a serial console by the excitable lads doing things likely to break startup.

It affects battery life because in the device there is no grounding, so it is likely to have an irq storm.
Also level shifters are missing. However the pads are probably the most easily accessible part of the interiors.

I assumed the luser-friendly Wiindows tool was just a cross-compile of the Linux flasher, wrapped in a pretty shell, so it could do it. But I suppose the image format does not contain flags to indicate add'l changes, so it couldn't just be pushed as a new OS image.


Igor, you saying there'd be no substantial battery drain from the serial con if you put a pull-up/down on rx? (When not in use, of course.)

The thing is, right now Nokia doesn't even really make any CDMA phones. (Any that have Nokia's logo on them are ODM units made by other manufacturers, or units that were designed at least a year and a half ago, as far as I know.) Their sole CDMA R&D center (in San Diego) laid off 1/3-1/2 of its employees about a year and a half ago and switched to working on GSM phones. So I'd be really shocked to see them put 1xEVDO into an internet table.

If the serial driver is in good shape.

Which might not be the case. The driver alternates between gpio mode and serial:
* after a timeout serial mode is disabled and gpio irq is used to detect activity on the RX line (this trashes the first bit - it would be possible to bitbang the whole first byte and then switch to serial mode, but that's not the case)
* when the irq is rised, the muxing is reverted back to serial mode

But this driver is not part of the deliverables for a stock kernel, so it doesn't get really tested.

Re: The Nokia N810 - WiMAX Edition
 
I made some "x-ray" images from photos in the fcc documents to get a feel about how the n810 is constructed. Notice the large empty area on the right side of the picture above the battery. This is behind the plastic antenna cover. The wifi/bluetooth antenna is visible on the left side in the second picture. Also note the pads on the far right side, so theoretically they could just solder a wimax module in. I think that they would make a new board design for the wimax model. They probably could have included the FM radio or a full size sd card if they weren't saving space here.

hey Igor...

Just wanted to ask you an off-topic question. Will the video bandwidth issue be ultimately resolved as many people are complaining about the lack of good video support. You can ignore the post if you dont want to answer.

Re: The Nokia N810 - WiMAX Edition
 
i know theres no simple answer, but Antilles do you have an idea of why the 800/810's OS's are so sluggish compared to the Touch's?

Benson 2008-03-31 22:39

Re: The Nokia N810 - WiMAX Edition
 
Cool, SDRman. Anyone have any clue what those pads are up in that corner? Is there something attaching on the front there?
(If that's some sorta data bus useful for connecting WiMAX, it could be useful for other things too. But I'm with you, a new PCB seems likely.)
I guess we'll know when (if) thoughtfix gets one.

If that space is really empty, there's uses even without that bus; run wires down to the USB port, with a switch to disconnect <whatever gadget you put there>. I don't think a typical 3G USB dongle would fit, but if you could cram it in...

so then has there been a second filing with the FCC that goes over the WiMax edition yet? or are they waiting till after tomorrow (april first)

I can provide the basics (I'm sure GA can answer better though):

-general purpose, mostly-open computer vs more narrow-focused, tightly-controlled device

-Linux on a mobile device

-optimization choices

-hardware design choices

Ummmm.... Linux on a mobile device vs. BSD on a mobile device? I'm not sure that the kernel and other low-level stuff has any real performance difference.

True, true, but, technical semantics aside, I believe Texrat was referring to the whole almost-fullsize computer operating system versus highly mobile-optimized limited OS.

I drastically oversimplified, and condensed a TON of issues into that one statement. If you start thinking about it, I'm sure you'll realize why. ;)

In case you haven't noticed, the device can play sounds. Those pads are for the speakers.

Benson 2008-04-01 14:55

Re: The Nokia N810 - WiMAX Edition
 
9 pins? for speakers... Seems odd, or are we not talking the same pads?

Texrat, I didn't answer, because the only answers one can give are drastic oversimplifications, hence wrong. But if I had, I'd have gone for this sort of oversimplification:
Because the Nokias can do stuff.
It seems wrong in a less harmful way. And as useful, in my opinion (which is that no answer to such a broad question is useful...)

But I'm sure OpOfIg found your answer more helpful than mine would have been, so carry on!

No, you're not. igor is talking about the speaker pads that were mentioned in the x-ray post, and you're talking about the Cold Flash/serial pads.

The xray pictures looks completely different than it did the first time around, I swear! ;_;

Ooookaay, picture time.

From SDRman's post, I thought he was suggesting WiMAX could connect to the nine pads below. So my comments have been referencing that. The seven pads under the battery look like a cluster of seven pads in my N800; I thought these were the serial console, but not sure. The four pads are not quite the same layout, but I still identified them with a cluster of four on my N800. I was thinking JTAG, as I'd heard there was a JTAG interface, but I haven't really looked into this stuff much, having heard that it was a battery hog. (Both these clusters are accessible through shielding cutouts on the N800)

None of these look like speaker terminals to me, but I don't really know...

jolouis 2008-04-01 17:03

Re: The Nokia N810 - WiMAX Edition
 
Just to throw in my two cents on the whole "pads" discussion here.. the 4 off on their own (at least on the N800, don't know about the N810... assume they correlate to the ones that are circled in green) I would put heavy money on being header pins for USB. If you check them you'll find that when you put the tablet into USB Host mode, one of the pins goes 5V high just like it does on the USB connector. I got myself some pogo pins a while ago to test the theory but never got around to actually doing it...

As for the rest... well somebody mentioned serial/JTAG, which on the N800 again I know are part of the other group of pads that are exposed right beside the battery through a cutout in the sheilding, but I haven't investigated those myself...

Texrat 2008-04-01 17:08

Re: The Nokia N810 - WiMAX Edition
 
The 4 in green are used for factory firmware flashing.

That is magnificent. :D :) :cool:

If you want Wimax in Canada, you're going to be forced to buy that monolith anyway (I dare you to get Portable Internet but not buy the modem). Why are they selling such gargantuan monstrosities, especially if Nokia is able to jam the same hardware into a corner of the N810?
