I have a technical question ... you can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?

Yes I understand ... so it is not technically possible to manage wifi and 3g antenna at the same time because data can only handle one job at a time? I thought the wifi module and the module 3g were managed separately...

This is an android software limitations?

When you use the wifi 3g module is put into the off state to save battery, works only the incall module. When you disable the wifi 3g module change the status to up. About your question no, it's impossible to use wifi and 3g at the same time to make 2 different operation

thanks for the reply. just in my office I have a wifi router with no internet connection, are connected with the phone to surf the intranet. so I would keep the connection 3g to receive notifications from whattsup or other ... every time without having to turn off and on the wifi. It does not seem like a stupid question.

Yes, I'm doing it on my Nexus 4, check this thread:

Another guy is doing it on an Optimus G, he did it first as far as I can tell:

Simply put no. Phones are not made to use 2 different wireless signals at once.
...
There is no way around it

That's incorrect. Android phones can use multiple wireless signals at once (wifi, cell, mobile data, bluetooth, nfc). And they can have multiple network interfaces up at the same time just like any linux box can. It just happens that the network manager turns of mobile data when you turn on wifi, but that's on purpose (to save you battery/cost), and not because the phone isn't capable of it.

Not sure why you say with such authority there's no way around it. If you don't know the answer to something for sure, better don't give a wrong answer.

There's even an app on the play store that can loadbalance a download over wifi and mobile data at the same time:

I say this from past experience that the WiFi antenna could not get a signal at the same time as the data antenna.

Now while this may have changed. I will look into it myself before I pay much heed to it as anything more then smoke and mirrors.

Welcome to the future, I guess...

But this has been around for awhile (though not as advanced, obviously...)

But as far as being able to use both separately at the same time would probably be a pain to implement in many phones.
