Nano-SIM Decision Delayed
judgecorp writes "The decision on the next generation of even-smaller SIM cards for phones and other devices has been delayed by standards body ETSI, and the issue (which should have been settled this week) is nowhere near resolution. Apple wants to trim the existing micro-SIM further, Nokia wants to move to something like a micro-SD card which may involve patents. Meanwhile RIM has complained about Apple's approach."
I'm struggling to handle these things with my fat fingers already. And devices are getting so small that you have to wonder whether, if we want any foorm of interaction, we are on the edge of small enough. Now capacity and power, pile it on.
Because without a separate card, you get the Verizon/Sprint problem of refusing to activate devices that don't exist in their ESN database; i.e. devices that they didn't sell themselves at markup on extended contract. The SIM standard at least gives the telcos a (semi?)-secure method of identifying subscribers for billing purposes, while keeping them out of the business of dictating which devices are allowed on the network.
Yeah, fuck Apple! They're trying to get a royalty-free standard for a tiny SIM card established! How dare they!
Tme for all the hypocrites to come out against apple who is offering a free, perpetual license for the relevant patents, in favor of those who won't do the same, only because they have an irrational hatred of apple. Just look at the first post.
The are offering a 'free' license only to anyone who licenses their patents under the same conditions. That's not really 'free' that's 'Apple is tired of getting charged license fees by people who've been doing phone R&D rather longer than they have'...
The SIM isn't just a memory card. It also has onboard processing. Not much, but just enough to perform a handshake: The network actually authenticates the SIM itsself, with the phone just acting as a network interface and power supply. That way it is practically impossible to clone a SIM (There are ways, but they are far beyond the abilities of even most specialists in the field). As for why they are used, it's a regulatory thing intended to decouple the network operators from control of the devices, which could be seen as a conflict of interest or as a way to prevent customers from moving to a new operator (If they couldn't just move the SIM, they'd have to buy a completly new device).
Except that Apple didn't do anything except trim down the current version of the SIM card leaving only the metal contacts. There's nothing in the proposal by Apple that Apple actually created. They are essentially saying "I'll license 'trimming a normal SIM down to size with a razor blade' for free! All we ask is that you offer the same deal if your proposal is adopted."
It's... weird.
Of course it's "royalty free." There's nothing about it which is worthy of collecting any royalties.
My guess is the amount of space they take up in the phone is the problem. Basically, between the SIM itself and the hardware for reading it, that's a good amount of real estate.
Exactly.
But the problem is the insane rush to thinness. Devices are already too thin, and making them thinner just makes them harder to use, hold, and keep rigid enough to prevent glass breakage.
The problem is that current battery technology wants to be in regular shapes, and in order to allow for a sim socket you have to surrender the entire width of the phone even though the sim only takes a portion of that width. I suspect Apple would like to insert the sim in a slot that sits perpendicular to the slab. These nano-sims are also thinner.
Molded batteries would allow the use of irregular areas inside of a device, and such batteries could better use empty space.
Linear sims (toothpick) are another possible design. The phone need only read them upon insertion via a collar around the insertion hole. Nobody bothers to write to the sim any more.
Sig Battery depleted. Reverting to safe mode.
