At our office we have bad reception for 3G. We bought a Femtocell device that provides a 3G connection for one specific mobile provider. This device is connected to our network via ethernet. I cannot use this device at our office, because I use another provider.
Thinking about this - it could be that I use connections like this without knowing it. Take imaginary John, living in an area where connection is bad. He has bought and installed his own Femtocell at home. Not only he connects to this device, but everybody in range of this device - not?
When my direct connection to my provider fails, and I'm in range of John's home femtocell, my SMS, phone conversations and internet data are transferred over his home network.
- Is this traffic encrypted and safe?
- Is it true that anybody can connect to this device and use bandwidth?
- When a phone connects to this femtocell, does it have access to the local LAN?
