Just bought an XDA2 - partly because I understand WiFi add-ons will be available soon.
Any news on this - or, if they are out there, anyone with experience.
My home wireless network is Apple Airport, by the way, but includes a PC without problem.
Thanks...
I didn't believe there were any plans at the moment for a dedicated Wi-Fi backpack. Instead take a look at the SDIO Wi-Fi card being offered by SanDisk:
http://www.sandisk.com/retail_sdwifi.html
My friend thought he had picked up somewhere that the XDA 2 had an internal slot that is eventually going to be used for wi-fi. Can anyone shed any light on this?
I certainly would prefer an integrated wi-fi solution so that I can use the sd slot for whatever I decide.

havent heard about a wifi backpack apart from speculations from people here
but i have heard about an upcomming sdio wifi card which also had connectors for sd ram cards at the same time
SD Wi Fi with256Mb of storage
Check this link out, This could be an answer to many problems.

"My friend thought he had picked up somewhere that the XDA 2 had an internal slot that is eventually going to be used for wi-fi. Can anyone shed any light on this?"
I think this is related to the marketing hype generated by O2 etc. Essentially they are referring to the capability of inserting a CF card based WiFi solution into the XDA2 backpack.
For all those who are mildly paranoid about being monitored how much do we really know about the following: The XDA2 changes hands, is the original owner's info still linked to it; the XDA2 is barred, when using it as a PDA does it still send out signals? if so, can these signals be located? can the XDA2 be used to surf without a sim card, if so, are the signals posted to anyone? Can the XDA2 be unbarred? If it can be, is it hardwired to retain its original ID? Does all this sound like the Matrix ... well it may well be! :roll:
sounds like u got sum good dope
email me
LOLLLLLLLLLLLLLLLLL
...but seriously...

When the radio is switched on the xda sends the imei whether a sim is in place or not, the information of a previous owner is lost once a hard reset is carried out, however some people think that by unclicking permanant save, that the data is lost, well that isnt true because if the next owner switches it back on and you were using the feature before, he will have access to all your data, the only way I found was to delete all contacts, check permanent save, reboot then uncheck it. There is no way known at the moment that is public knowledge that allows you to manipulate imei on xda2. I understand that there are calls from the uk government to have all imei numbers in hardware rather than firmware/software to make it almost impossible to change identity. Just because you are paranoid doesnt mean they arent out to get you. :shock:
Thank you you seem to be THE authority on XDA! You say ""When the radio is switched on the xda sends the imei whether a sim is in place or not"" I am not sure I understand the concept of 'radio' in the xda2. can the radio be switched off/disabled? what signals are sent and how are these managed, by whom? because there is now billing requirement why should this radio signal be monitored? It has been also said that "Paranoia is the belief in a hidden order behind the visible." anon (why do u think he chose to remain anon?)

If you suspect they are listening, well, they are and all you can do is to make a little harder, thus:

Wish I was smoking something man! Maybe some food poisoning from bad lumpia :?
I was in a security presentation and saw how a secuirty engineer from Motorola was able to pinpoint and triangulate 17 different phones in an auditorium and then go down to each unit and "clone" it for surveillance purposes with a GUI application in his laptop. ( With the users permission for the purpose of the demo!)
If they are showcasing this technology, then I guarantee Big Brother
( NSA and NRO specifically) have the capability in a more advanced form and blend it with Exchelon, key word analysis and the like....
have a look at www.followus.co.uk its excellent we use it to track the kids, ( the more cell sites close by the better the fix) its show us they are at near by to where ever they say they are
Yes, I am aware of that service.
It is a good thing for parents and businesses and is not infringing on privacy because it is consentual and voluntary.
It amazes me to see how many peope think cell phones are not easy to trace or tap because they are mobile!
Having started this thread, I was begining to think no-one cared!
Is it worth pulling together all the intelligence on remote monitoring in one place? The benefit of this will be to know what currently done and if it is at all possible tweak the systems to ensure a modicum of privacy.
There is all sorts of legislation protecting privacy and some ensuring civil liberties. What are the implications of mobile phone contracts, for instance? Do they have a duty of care to protect our privacy is there anything in the contracts that limit their liability in this regard, and if so, why?
oh ... and I don't smoke but I'm told that I don't need to!
Hello everybody,
I am using an XDA2 (=iMate) which sports a SDIO slot; furthermore, the device is listed in sandisk's compatibility listing. To connect to our wireless network (811.b), I use the Sandisk SDIO-Wireless-Lan-Adapter. I had no problems connecting to the access-point, I get a stable connection immediately, the indicated connection speed is 11 Mbit/sec. Since the distance to the ap is very small, link quality is near 100%.
The problem is that the maximum transfer performance I get is very poor. I get no more than 250Kbit/sec (=30Kbyte/sec), no matter if I do webbrowsing or simply copy files from other computer in the local area network. This is nothing compared to the ~5000Kbit/sec (=600Kbyte/sec) that an 811.b adapter should be capable of. I tried changing channels, but that did not change anything. I also hard-reseted my xda2 and installed nothing but the sandisk-drivers...no changes. Alternatively, I tried the driver from socket....works, but no changes in performance.
I have got the same problem at two different wireless networks (at work & at home), so it seems that the problem is on my system. I cannot test more than these two networks, since I do not know any others.
Has anybody got an idea what could cause this problem? How fast are your XDA2s with SDIO-Wifi?
Thanks in advance,
Stephen.
I had the same problem I returned my card and got a Socket one instead (from Expansys) I worked immediately.
After I returned it I read somewere that you must set your access piont to work at only the slower 11mbs and not the faster 22 or 56mbs and that will resolve the Sandisk problem.
I cannot verify this as I had returned my card, but my access piont was a Dlink one runnig at 56mbs

hi stephob12,
after reading this read i have googled around and found an article about socket sdio wlan card in a german computer magazine. the wrote that the sdio-specs do not allow transfer speeds > 35,7kb/sec regardless what sdio-card you are using (sandisk or socket). your performance of about 30kb/sec is really near the theoretical maximum limit.
i have no experience with those cards but i had planned to purchase one for my xda2 but i am slightly disappointet about that sdio limit :? . at home i use a bluetooth connection to my dsl access point and the speed is very good especially when you know that bluetooth with its 723kbit/sec is much slower than 802.11b with 11mb/sec.
i will now overthink whether to purchase a sdio wlan-card or not. at least not for the price of around 100 us$ or euros they have at the moment.
regards
peter
Hi,
can you post the URL of the article you found?
or send it per PM if you prefer ...
and what do you mean with "socked one", which one is it ?
and no one has any information about how the Compact Flash one is working, by using the back pack - this would be an alternative, don't you think???
ciao
the card is a "SOCKET" you can see it on www.expansys.com it is offered as an alternative to SANDISK at thew same price.
Thank you for the quick answer,
now I sow it, it seems to be more interesting than the Sandisk, I wanted to buy one ... but in that case it is worth to wait, to find a Socket near to where I live
May be I can find it in China or in the USA,
there is another brand - I forgot the name - which will be sold soon at CompUSA ...
I'm trying to find it ...
wil post it when I got it

Cheeper SanDisk SD WiFi card
Hi,
i think ive found (cheers google :wink: ) the same SanDisk wifi card u guys were talking about for $85 US (£47 GBP sounds much cheeper) at blueproton.zoovy.com so i was gunna ask if ne1 had ne experience with them but u obviously do.
just a couple of questions, am i right in guessing that SDIO stands for Secure Digital Input Output? how secure are these devices? what sorta encryption base do they use? and does ne1 know if there is any talk of bringing out a faster (22g or 54g) card on SD or CF?
Cheers
Smiley
Smiley,
SDIO WiFi card offers you WEP with 128bit key and this is your basic Wifi security. I am not sure if the SDIO card does any encyription. I suspect not.
As far as I know there is no 802.11g card (SDIO or CF) yet. I just read the news about a 802.11g chip for mobile devices. See below :
http://www.infosyncworld.com/news/n/4968.html
This may mean we may see cards based on this chip in the future or there may be products using this technology to deliver built-in Wifi capability.
Hope this helps. Regards

does this mean that the socket one works at the full 11mbps withought having to downgrade ur main network? :?

Hello all,
I've got this Socket SDIO WLAN card, and it's terrible with regardws to throughput, but it's okay besides from that. I can't even stream a 300kb/s video, and that's not impressive... In cradle via USB it's of course okay, and having problems with SIP VOIP client as well, very very sad.. I wrote Socket, and got a reply that indicates they're sorry for this, but that it's caused by some HW-related issues on my device (QTEK 2020)
Urgh...

Finally…some competition to Sandisk / Socket SD WiFi
Do you want to connect to your WLAN ? No problem…
Mobile Planet is selling the PRETEC SD WLAN cards.
Installed one yesterday…works like a charm in my MDA II.
After playing / experimenting (but never being able to reliably use it)
with Sandisk and Socket cards I have now 100% reliable WiFi connection.
at what speed and i'm not talking about the reported connection speed but the real world speed
thinking if the sd interface can reach those 11Mb speeds when sending
Speed...oh well, I'dont have any tools to test it.
POCKET SKYPE works...
Speed...oh well, I'dont have any tools to test it.
POCKET SKYPE works...
I have to comment on Mobile Planet... It took me a year to get off their spam list after ordering from them once. Never again.
@vegasmda: you should replace the link in your posting by a more anonymous link (just for security reason). the current link leads directly to your basket Stanley...
i do not know what misuse could be done by this i feel that it's better when nobody directly lands in you basket.

CF Wireless LAN card
This is just to report that I just bought and fitted a ProLink WL201 wireless LAN card and it works like a treat, including with the access point our local pub landlord has set up. I'm very pleased with it as I can now answer all the quiz questions that I don't know. As this CF card is about a third of the price of many others, I thought you'd like to know.

Are you using the backpack, or do you mean it's an SD card?
Thanks!
CF card in backpack
wtharp2, It's a CF card in the backpack - a little cumbersome but it saves a lot of money in UK as gprs is expensive with O2. Regards, Derek
My G2 with Cyanogen 6.1.1 is still only showing 1.28gb internal memory, does that mean the stock crap is still locked up somewhere? I really hate how they advertised it when it was never available in the first place

This is from the HTC Vision Wiki about the memory,
The Missing 2GB
11-12-10: The following is our best understanding of the issue at-present. Scotty2 says this is "99.9%" the issue and "the only explanation that makes sense."
What Missing 2GB?
Although marketing from T-Mobile claim the phone contains 4GB of internal storage (not including the removable micro-SD card), once the phone was released, users quickly noticed that only ~2GB appears to exist.
Several theories for the "missing" flash memory storage were proposed, including a possible "shadow" installation of the operating system being hidden somewhere, as well as a possible 2GB limitation of the card when in "byte" rather than "sector" mode. Still a third theory proposed that perhaps the extra 2GB were somewhere outside the normal block device where the Android kernel's flash controller couldn't find it.
Apparently, none of these theories were correct.
So where is the missing 2GB?
To answer this, it is first necessary to understand a bit about how internal flash cards, such as the Sandisk card (also known as an "emmc") on the HTC Vision, store information.
Luckily, Sandisk has provided a helpful video. Pay particular attention to the discussion of SLC (single-level cell) and MLC (multi-level cell) in Chapter 5.
In an SLC configuration, a single bit is packed into each memory cell. In a multi-level cell, you can fit 2, 3, 4 or more bits in each cell. You get a lot of capacity with more bits per cell, but at the expense of speed and reliability.
In trying to figure out where the missing 2gb went, scotty2 noticed that most of the Sandisk card's block device (that is, the part with Android on it) had been partitioned within the regular "User Data Area" as an "Enhanced User Data Area".
Note that when we talk about partitioning the emmc, we're not talking about regular MBR partitions like /dev/whatever. An emmc partition is a very low-level partition of the flash. Each emmc partition constitutes a full block device, which can then be further partitioned into a bootloader, /system, /data, etc.
The card's datasheet wasn't too clear about what the "Enhanced User Data Area" did that was so different from the regular User Data Area, although one thing was clear-- once its parameters was set, you couldn't "un-set" it. To quote the datasheet, the Enhanced User Data Area "can be programmed only once during the device life-cycle (one-time programmable)."
But why was the entire Sandisk partitioned in this special "Enhanced" User Data area? No one knew.
Then tmzt found this. It's an article by Toshiba that suggests what's going on:
Those areas requiring better reliability are SLC or can be programmed as SLC. . . the Enhanced User Data Area, which may store, for example, system log files, are SLC. The User Data Area, which may store music, pictures, videos and other files is MLC. . . Each 1 bit configured as SLC results in 2 bits less of MLC. Theoretically an 8GB e-MMC device (densities are defined in MLC terms), could be configured virtually all as SLC and thus would be approximately 4GB. In most cases, it is more likely that the majority of the memory would be configured as MLC to support higher density.
You've probably figured out by now what's likely happened here. Assuming the Sandisk emmc works like Toshiba's, the 4GB flash has probably been, save for a few tiny partitions such as the radio, irreversibly configured to use SLC, rather than MLC. If so, the benefit is faster performance and perhaps greater stability (and more read/write cycles). But its capacity/density would be cut in half.
And that, my friends, may very well be where your 2GB has gone.
So To Conclude...
Assuming the above is a correct understanding of the issue, the following appears to be the case:
The HTC vision has a 4GB firmware card
It has been irreversibly partitioned to use a faster/more reliable configuration called SLC
This has resulted in a practical capacity/density of ~2GB
Update: Initial investigations from over a month ago reported that T-Mobile attributed this issue to "creative partitioning": ("I called into T-Mobile Android support and was assured this number is correct, and that I do have the full 4GB storage on-board... there's just some "creative partitioning" going on.") This may correlate with the explanation provided above.
Update 12/6/10: A more technical discussion of this (with pictures) is here.
