Vodafone, Optus Femtocell trials not impacted by UK vulnerability

Femtocell devices have been used by telecommunication companies around the world for sometime, and work by using a home or office fixed-line broadband connection to extend a 3G signal in areas where coverage may be poor.

"A Femto is linked to the Vodafone core network via your home Internet connection. The Femto uses this access to retrieve the secret key material of a Vodafone customer who wants to use the Femto," the group explained today.
