need to controol and send a video through 3G mobile phone

[meamem]

please is their any one can help me to understand how to control 3G mobile phone
could any one where can i start search about what mobile phone i can use and what is the micro controller i can use to send data from a camera to mobile phone by the controller and make a video call with the video coming from the camera I need help please i want this in my home work pl

Buy a modern smart phone they do this already. There is no practical way to implement this yourself on a small scale at a reasonable costs with any usefulness.

i'm glad you choose this conversation but the problem i need the AT command that program the mobile phone or sit the mobile phone into making 3G calll the problem not doing 3G call i need the paramters for it and the commmand that i got it from searching was AT+CBST=(three parameters i don't know what they are making

If you use the phone as a modem you'll be stuck with modem speeds (very very slow one's I might add), they won't be 3g speed (regardless of the network you're on) there is no way you'll ever get 'video' out of this kind of connection, you'd be lucky to get still images in a reasonable period of time (and that's with no audio)

A simple Google search will **broken link removed** on that AT+CBST command.

Thank you for the link it's very helpful but how the 3G phones do this
i think there is a camera do this work i want but it will coast me 3000 dollar for one came imagine the price with at least 10 or 5 cams
i don't remember the cam name

Looks like you have a lot more research to do meamem.

You will need a decent 3G module, and something like an ARM processor, running Linux would help as you can use that as packet router, and it will require also USB host, which an ARM type processor will have. Microcontrollers do not have enough memory to swap all of these bits and bytes to process video, still images are OK, as long as you are not processing it, and just passing the information on.

One well known manufacturer (AXIS) used to make an ETRAX processor, which was basically an ARM core with POP memory, making a SoC running a Linux distro for video (MPEG / MPEG2 / MPEG4) processing.

Plenty of ARM open hardware stuff out there.

I was thinking using outer switching without putting the micro controller in the way of cam streams using multiplexer for example.
high speed MUX or ultra speed i think this will solve the problem of the slow micro-controller and I'm not very powerful in using arm if you could send me site that explain how to use ARM .Thank you in advance.

Well if you have a access to a wifi hotspot get a cheap ipcam.
like this one
**broken link removed**
I have 4 of them.
the only big con is that if you want to use the audio functions you will have to use IE with active-X installed
and no windows 7
but the great thing is that is has it own free DDNS service. and you can set the port to any thing you want
so if the wifi hotspot blocks certain ports you can get around it.
And you have pan and tilt controls.
and you even have some hard wire interface on input and one output. At 5v TTL
some models even have a 3X optical zoom. but around $100
The above model is ~$50.00 with shipping.

This is not related to what I want.
what i want is 3G. something can be manged from large distance and not very cheap but reasonable price.

Then get a 3g wireless hotspot and let the ip cam connect to it.
Then you can connect to it via the internet from anywhere in the world.

Olimex have some good demo boards, might be worth looking at!
