The 3G mobile broadband network is being put under the pressure, not by file sharing or video streaming, but by the simple email.
It seems that while surfing the internet, downloading files and watching videos, all feature in the make up of mobile broadband traffic these are not responsible for putting pressure on the network.
According to Bell Laboratories, it turns out that email is using up more bandwidth than any other application available to users.
This puts a different perspective on what mobile broadband is being used for, after all it is only in the main cities and airports that higher connection speeds are available to users.
In other areas, the connection speed can be as low as dial up internet and therefore surfing the internet is a bit of chore when pages take so long to load.
