This device, would be used for
* "find me" devices that ring or notify their location, when
accessed,
* open or better yet lock door and gate, and notify if
locked.
Good for garage, car, home etc.
* control machines of any sort, including bicycle rental,
vending machines, remote controlled
vehicles, and any
mechanical or computerized device you can think of.
Arduino GSM Shield
http://arduino.cc/e...in/ArduinoGSMShield
Connect it to your Arduino microcontroller and plug in a SIM card, and you can control your Arduino via telephone or SMS. And the Arduino can control pretty much anything, so there you go. [ytk, Jan 08 2014]

So, when someone dials a wrong number, your house
gets unlocked, but neither you nor the someone
knows about it? |
|

Umm… This exists. [marked-for-deletion] |
|
| |
Wow!!! Thanks for the link. |
|
| |
But I'm talking about a tiny PRODUCT that's inside
OEM products, sold by cellular companies. No SIM
but rather controlled through a unique ID. So
please unMFD it. Note: [business: cell phone
network] |
|
| |
And Vernon, that's not a problem. The signal is
secured, and to access the device you may need
to go through a password system. The actual
access is not done through the regular telephone
system (hence: no SIM) and even if it would be,
there still are many other ways to secure the
access, with various levels of permission. |
|
| |
Plenty of IP-aware devices like door and
heating controls out there already. Many
even have wifi. |
|
| |
Linking telephony to a pc is very, very baked. |
|
| |
Using a pc to control multiple devices over IP
via hardwire LAN, 802.11, Bluetooth, CANbus,
RS232, RS422, CAMAC, even IEEE488
(remember that ?) is WKTE. |

Suggested-for-deletion, no innovation here. |

How do you think they get the chip that goes on that
board? It's a tiny product
inside an OEM product. And you can't really connect
to a cell network without a
SIM anymore. Cell companies don't generally
manufacture the equipment, you see
—they just authorize the equipment to use the
network. The SIM is what controls
that authorization. Talking about a cellular device
without a SIM is like talking
about a car without a license plate. Incidentally, you can get SIMs that have no phone
number attached, and are
only usable for data. These are commonly found in tablet devices that have GSM
connectivity. |
|
| |
The reason you don't see a lot of random devices
connected to the cell network is
not because nobody has thought to do it before, or
because it's technically
infeasible. There just aren't that many applications
for such technology. |
|
| |
In terms of the applications you describe: “find me”
devices already exist. My
phone does just that, and there are other products
that you can attach tags to
that work over Bluetooth and other protocols to
provide similar functionality. But
connecting a random device to the cell network just
for the purpose of being able
to find it if it's lost is generally cost and power
prohibitive. |
|
| |
As for opening and locking gates—there are already
plenty such devices. In fact, I
saw a remotely controllable garage door opener for
sale at the Apple store not
too long ago. My thermostat is controllable from a
phone over the Internet. But the vast majority of home
automation devices that are remotely controllable
use a wi-fi connection to the
Internet, which has the advantage of not requiring hefty
subscription fees. Since these
devices are deployed in a single location where wi-fi
is generally available, it's a
much more logical choice. But there's no reason you
*couldn't* design such
devices to use GSM. It's just that nobody wants such a
thing. The few people who
do could probably hack something together pretty
easily with a personal hotspot
device. |
|
| |
The remote machine control is a good idea, but the
problem is this is already
very, very common. Everything from vending
machines to rental cars to parking
meters can be equipped with a GSM module, either to
remotely control and monitor
the device, or just to process credit card payments. |
|
| |
There's really nothing new to this idea at all, I'm
afraid. The MFD will have to
stand. |
|
| |
Yeah but he's talking about a tiny PRODUCT that's inside OEM products! |
|
| |
Ah - wait! Did he say _tiny_?? |
|

// * control machines of any sort, including bicycle rental,

|
| |
...car bombs, IEDs...by all means, we should make remote
detonation of homemade explosives easier. |
|
| |
I can say with 100% certainty that the type of person who is
inclined to remotely detonate a homemade explosive will
not be deterred in the least by difficulty in finding a means
to do so. For a lot of reasons, not the least of which is THIS
IDEA ALREADY EXISTS. |
|
| |
Besides, I figured you of all people here would be above
playing the “what if the terrorists get ahold of this” card.
[Alterother], I am disappoint. |
|
| |
I admit it wasn't my best work. |
|
| |
This idea is NOT about a WIFI controlled device. |
|
| |
This idea is NOT about a Bluetooth controlled
device. |
|
| |
This idea is NOT about a PC controlled device. |
|
| |
The idea is that it is controlled DIRECTLY by the
cellular network complying with the ITU directives. |
|
| |
And I am talking about developing a device at the
cellular device hardware manufacturing level.
Nokia
or Samsung. So that this device IS the SIM (with an
extension) or in other words, the SIM will be
"embedded" inside this device. |
|
| |
My emphasis on Tiny and OEM was in answer to
the
Arduino controller which needs 5 volts, is large and
only works in conjunction with Arduino. |
|
| |
And about terrorists and terrorism, I don't think it
will have any "impact". Technology is not the
issue, not for the terrorists, and not for getting
rid of terrorism. |
|
| |
What's the point of "embedding" the SIM? You're not
gonna make the device any smaller or cheaper that
way, you just end up with a more expensive, less
reusable device. If there were any point in doing
that, they'd be making them that way already. |
|
| |
My first thought was something to do with Thomas the tank engine. |
|
| |
No need for remote, no need for magnetic card. It
works from your phone, or from ANY phone. |
|
| |
The SIM is good for phones. This is an "enabling
device" which looks like a SIM and is connected to
another "accepting" device like a lock, or a
beeper, or a hot water faucet. After being
registered (online) it is activated and ready to do
its job. |
|
| |
There are many uses for this type of device, from
a parking-card to a hotel room lock. All with no
need for a key or for a remote control any more.
All through you phone. |
|
| |
Before you ask me how it will work as a key if ANY
phone can access it, think of the possibilities, I'm
sure you'll come up with at least 10 ways to
protect it. Oh, and secure communication of
course is built-in and part of the device. |
