Wi-Fi In a SIM Card

gaijin_ writes "What if, rather than buying a MiFi or using a Wi-Fi router app like those on the Palm Pre Plus, you could stick a SIM in any device and have a shared 3G connection? That's what Sagem Orga and Telefonica are promising: they've developed the SIMFi, a USIM card with an embedded Wi-Fi radio that, when dropped into any standard handset, can share the 3G HSPA connection with various Wi-Fi clients as an instant access point."

I'm wondering (1)

poetmatt (793785) | more than 4 years ago | (#31119264)

Beyond that my instinct says this could be huge, how big of an impact does a product like this really have? Mind you, the questions of implementation and all that aside, is this really practical or just another thing that might eventually be a standard feature?

ircmaxell (1117387) | more than 4 years ago | (#31119372)

I think that will depend on the control you have over the functionality. Will the handset be aware of the radio? Will it be able to control it (turn it on and off)? Does it support encryption?

OTOH, it could be a portal for providing ubiquitous coverage for WiFi. Imagine having a city full of people with these (Even with reduced range to reduce the clutter). Then you would be able to access a "hot spot" from just about anywhere. Of course you'd be charged for access (by the provider most likely), but still it's a pretty cool idea...

Well, someone would be charged by an ISP for a connection to the internet, but you don't necessarily need the internet. It's easy to imagine a free mesh network running over nodes like this, with everyone running as a repeater for the common good. Various local services (bus schedules, local maps, restaurant locations, ordering a cab or a pizza) could be made available by servers connected to the mesh network without anyone paying for an internet connection. And of course people could run free exit nodes off their spare bandwidth at home or something to give the network some tenuous internet access.

SIM cards often expose customized menus to the phone. Or, describing it other way around, are allowed to take over the phone. So I guess there is a possibility of sensible integration.

Macfox (50100) | more than 4 years ago | (#31124102)

It's call STK or SIM Application Toolkit. Fairly old GSM standard. A small update for 3G was made a while back. http://en.wikipedia.org/wiki/SIM_Application_Toolkit [wikipedia.org]

STK is clunky at best. It's a polling arrangement. The phone polls the sim and it then replies with what it wants the phone to do. You certainly couldn't get the throughput needed via the SIM slot. I haven't RTFA but given it takes about 20-30secs to download 100 contacts from your SIM, it unlikely this new card would be using the existing standards or SIM slots.

It's for people who are too stupid to connect a cable. The cable connection can then be removed to cut costs. So everyone has to use wireless. It can probably default to unsecured, because those same people will also be too stupid to set up security. So at least you get so see what the person sitting opposite you is looking at on the Internet, if you are really that bored.

NightHawkeye (1721330) | more than 4 years ago | (#31119916)

Actually, I can already do this with my Nokia 5530 XpressMusic. It's a basic 2G phone with WiFi. Since it's 2G, I don't pay for data services. Yet I have access to high-speed capability whenever I'm at a WiFi hotspot. I couldn't justify the cost for 3G for the occasional times I'd want to access the internet. WiFi is a great compromise.

LWATCDR (28044) | more than 4 years ago | (#31120308)

None what so ever.
If you have a smartphone then you would have the option to use wifi.
If you have a feature phone you could use Bluetooth.
If you in the US AT&T and TMobile will let you use that sim when hell freezes over.
Really just about any smartphone could do this right now except the phone companies don't want you to do it.
You see you will have a much better end user experience using a separate device like a USB stick. And you would only have to pay an extra 50 to 90 dollars a month for it. So you see you are much better off not using any type of tethering.

T-Mobile at least has allowed Datajack.com to connect to their network, $39.99 bucks a month no contract. Device costs $99 to start the whole thing off, a total of $167.00 and you can Turn it off in any month you don't need to use it.

It has a HUGE impact. Now, when you go to a tech convention, instead of having crappy wireless at the convention center, you will have 5000 people, all carrying their own access points, trying to use the same dozen channels! Horray!

Re:I'm wondering (1)

aztracker1 (702135) | more than 4 years ago | (#31122158)

Probably unlikely for the most part. Especially since many handsets (smart phones) have hardware that already has a wifi device as well as the ability (hardware wise) to do wifi tethering. My jailbroken G1 does this pretty nicely, though I actually use the bluetooth option, and only allow my laptop to use it. Most of the carriers specifically don't want a single account to be able to share data with multiple devices.

Since most cellphones put the SIM card under the removable battery and the iPhone doesn't have a removable battery, I can somewhat understand your confusion, but rest assured that the iPhone does indeed have a user-removable SIM card (that is actually a requirement of the GSM standard).

iTouch! (3, Interesting)

sznupi (719324) | more than 4 years ago | (#31119976)

The other way around is much more interesting - get iPod Touch and, if needed, connect via WiFi and this SIM card; placed in a mobile phone that is, well, primarily a good phone. Cheap. One of those with uberlong battery life.

On a sensibly priced contract or outright prepaid (I can get 4 GiB, valid for 3 months (and if recharged again before that 3 month cut-off, usnused data are added to new portion), for 12 Euro; good enough)

Re:iTouch! (1)

mbourgon (186257) | more than 4 years ago | (#31120418)

I'd love to see that. I'm actually surprised no one's done something similar in hardware - while I carry a blackberry for work, I'd love to use its data connection on my Touch. Can't because the wifi radio in the bberry isn't built that way, but why not do something like that via bluetooth?

I'd be surprised if people didn't want to do something similar once the Pad came out - why pay for 2 data plans?

Re:iTouch! (1)

sznupi (719324) | more than 4 years ago | (#31120766)

"why not do something like that via bluetooth" - because Apple won't allow it (iTouch does have bluetooth...)

And there is a possibility via WiFi already - a software for some smartphones that allows them to act as a WiFi hotspot; Joikuspot for Symbian for example. But it's not very attractive IMHO - not only your particular Symbian phone needs to have WiFi, but also there's unnecessary overlap of functionalities between iTouch and Symbian smartphone. It would be much more lean if data access was provided via something like, say, Nokia 1208 even (a phone with ridiculously great reception and battery life; which I would probably carry with iPhone anyway)

PS. Not saying that 1208 would be a good choice, that phone doesn't even have GPRS ;p

But you get the idea; you can go really cheap if you just want a good phone with data access (they are way below $100 now; price without contract of course)

Re:iPhone (1)

X0563511 (793323) | more than 4 years ago | (#31120520)

Well, you would certainly have a hot spot. Cramming a wireless transmitter in a SIM card and having any kind of a respectable range, you are going to have a LOT of heat building up in that SIM.

The chipsets in consumer routers get very warm... and that's with the silicon of the chips, shielding, heatsinks etc. In this case, you'll have a tiny microcircuit in a piece of plastic.

How are they going to deal with heat?

czmax (939486) | more than 4 years ago | (#31119314)

This is a technical "solution" to a non-technical problem. The ability exists today but is predominately blocked by the cell phone providers.

This quote from the article shows how deluded these people are: "it seems likely that carriers would give the SIMFi away as long as you took out some sort of mobile data contract". If that was the case then I'd be able to use tethering on my iphone RIGHT NOW.

Sure, neat technical hack. Nice miniaturization there. But making this functionality available in a smaller form factor isn't the problem.

Re:solves the wrong problem (1)

marcansoft (727665) | more than 4 years ago | (#31119366)

Exactly. Any Wi-Fi card these days can work in AP mode, so any cellphone with Wi-Fi can potentially do this already. Manufacturers just don't care to do it and/or telcos don't care to allow it.

On an unrelated note, how on earth are they pulling this off? As far as I know, at least regular SIMs are limited to pretty low power, the data rate is really low, and they don't have access to the cellphone's data connection. I can't see this working unless USIM was expressly designed to support this kind of usage; it certainly requires a lot of cooperation from the phone, it would have to be part of the standard to begin with.

Re:solves the wrong problem (1)

nine-times (778537) | more than 4 years ago | (#31119992)

Yeah, I was just thinking the other day about how retarded it is that we can't do this. My phone has WiFi; I assume that the WiFi and 3G are capable of operating at the same time. My laptop has WiFi. I don't see any good reason why I can't set my phone to be an ad hoc network and let the laptop connect. If cellphone carriers are ok with selling you MiFi devices, then I don't know what'd be wrong with allowing users to do this sort of tethering with a phone.

Obviously they want you to buy a separate data plan for every device you want to use, but then why allow the MiFi?

Re:solves the wrong problem (1)

petermgreen (876956) | more than 4 years ago | (#31120786)

At least in the UK the mifi is marketed as a "mobile broadband" device with "mobile broadband" plans.

What the carriers don't want you doing is using an "unlimited" phone data plan with a PC because PCs can much more easilly use a hell of a lot of data. I doubt they would care too much about you using your phone to browse on a "mobile broadband" plan.

omnichad (1198475) | more than 4 years ago | (#31120724)

And then since there's plenty of combo bluetooth/wireless chips already in phones, there's no reason to put this functionality in the SIM anyway.

Re:solves the wrong problem (1)

jtownatpunk.net (245670) | more than 4 years ago | (#31120030)

Bingo. Carriers go to great lengths to make it a pain in the ass to tether phones and only grudgingly allow it in limited cases for extra money as long as you use their proprietary "dialer". They want the process to be annoying enough that people only do it when they have absolutely no other choice. There are plenty of smartphones with built-in WiFi but I can't think of a single branded phone (in the US) that has the necessary software installed. If carriers wanted to facilitate this type of thing, they'd already be doing it. Instead, we have to rely on third party software and, occasionally, "hacking" the device to restore functionality that's been removed.

owlstead (636356) | more than 4 years ago | (#31122518)

Meh, I can do USB tethering on my Android phone (Hero) right now. It's as easy as going into the menu and enable the tethering, and then plugging it into my laptop. I was a must have feature for me. No 20 euro additional charge - and for 30 euro a month for my ADSL I have telco WiFi access points to boot. Just don't buy an iPhone. I must admit that the persons in the telco provider shop were rather reluctant in admitting that it was possible.

PS for those in NL, that's KPN mobile and XS4ALL ADSL I'm using, I haven't had time to do tethering over my Bluetooth connections, and I heard it is tricky and consumes rather a lot of power if I could get it working. Nice thing is that the bigger laptop battery is also powering the phone if you use USB, but you do have a wire to worry about.

In many cases, such as this one, there is no need for perfect 1:1 VSWR [wikipedia.org] . In broadcast, you can have several kilowatts, or more, of RF power going into an antenna. A high VSWR can be very bad. When you only need milliwatts of ERP [wikipedia.org] , you can deal with inefficient antennas.

Finally, a way to tether with my iPhone.

upgrade dumb to smart phone? (1)

amigabill (146897) | more than 4 years ago | (#31119770)

This could be a start for those of us not willing to pay monthly data plan fees to get a smart phone out of our dumb phone. I don't want to pay a hefty monthly fee just to own a smarter phone. Oh, wait, I have Verizon, no SIM slot. So I can't use it anyway. What about a microSD equivalent, with some brains as well as a radio and of course some flash memory?

TFS mentions a "USIM", so this is CDMA technology.

I'm not sure about combining flash memory and a radio on one card. However, plain, old microSD wifi cards have been on the market for quite a while now.

Carriers will have a shitfit (1)

They won't like this one bit and go to great lengths to disallow or prevent it from working.

Given that the carriers distribute the SIMs for their networks, not hard for them to prevent it !

Not necessarilly;

There exist certain hacktastic solutions for inserting 2 simcards into a handset at once, and having both co-exist peacefully. If you were to do this with one that is a traditional phone SIM, and then have this special SIM as the other, you could do this on your phone and they would be hard pressed to stop you.

Most US carriers already officially disallow tethering preferring instead that you subscribe with an additional device (like an Aircard or a MiFi), and charge you a healthy premium for the privilege. In some cases you can fly under the radar, like with a jailbroken iPhone on AT&T.

My Touch Pro 2 on Sprint came with an "Internet Sharing" app in the programs menu, for sharing 3g over USB or Bluetooth..

I'm not so sure about that. (1)

Consider how much you have to pay for data when you go beyond a typical 5GB/month limit. I would guess that your wireless provider would be more than happy to enable you to quickly burn through that 5GB and start paying the exorbitant overage costs.

FYI: Telefonica is one of the top carriers of Spain and has a lot of international subsidiaries.

SIM=GSM (1)

markdavis (642305) | more than 4 years ago | (#31120064)

>What if, rather than buying a MiFi or using a Wi-Fi router app like those on the Palm Pre Plus, you could stick a SIM in any device

But you *can't* stick a SIM in "any" device, only in GSM devices. Won't work on two of the three largest carriers in the USA, Verizon and Sprint. To make matters worse, Verizon will still charge a fortune to do that, and Sprint dropped the ability to legitimately tether smart phones completely (although you can do it with the Pre quite easily, anyway, but it is not legit. Maybe Sprint will wise up and offer something official this year?)

And even if you had a GSM phone, it still has to be compatible, AND fit, AND drivers/software were available for that particular phone, AND the carrier had to somehow work with it.

Well, Sagem and Telefonica certainly aren't concerned primarily about limitations of US cellphone market. Telefonica cares mostly about their network technology, which is quite firmly in GSM family. As is 80+% of mobile subsribers in the world.

I don't expect any drivers to be neccessary; this solution seems to be precisely about NOT using "special" phone. SIM cards typically expose to a phone their customized menu item, so there's certainly a way to control any functionality added in the hardware of said card.

gad_zuki! (70830) | more than 4 years ago | (#31120572)

Right. Not to mention, whats the speed of SIM reads and writes? From my experience theyre unusually slow, like 14.4kbps slow. Its an ID card, not a fast storage option. A lot of good thats going to do you when that internet connection is a 1mbps.

Already does this using the hardware in the phone. I use it on my iPhone. It's also available for Android, Palm, Blackberries and Winmo.

(can also use USB for tethering, works better than Apple's own)

They'll cripple the feature. AT&T will complain if you use it.

This is very silly. Before people forgot about PDAs we had CF, SDIO, and SpringBoard. We don't need any new technology for small device expansion, instead of re-inventing it, we just need SDIO slots on phones. It is like we went backwards with technology.

Did I miss something? (1)

torkus (1133985) | more than 4 years ago | (#31123504)

Ignoring the technical challenges of getting a WiFi transceiver into something the size of a SIM card - how exactly is the SIM card trading data with the cell phone to begin with?

Cell phones have an open back door to their wireless data channel through the SIM interface? One that will, without software on the phone, just allow you to transport data?

Even if you CAN talk through the SIM card interface and for data around how ever you want - how fast is that interface? It's meant to read off SIM cards that hold a tiny amount of data. So little most internet speeds could transmit the entire contents in a single second quite easily. Or is the SIM card supposed to have some kind of BT transceiver in it as well to tie to the cell phone?

There's no detail in the linked article and...given that cell carriers lock down this stuff in the phone I fail to see how it's possible even if the miniaturization is practical.
