Femtocell are 3G mini antennas whose power does not exceed that of a Wi-Fi terminal and that allows, for example, a reliable relay of the signal inside. Already SFR and AT&T have tested these products with view to marketing them.
One of the main obstacles to mass usage has just been lifted. The 3GPP who enact the standards of 3G mobile telephony has just published a standard to ensure compatibility and inter-operatively of all the solutions that manufacturers start to propose. Better still, this standard will make it possible that millions these cells can cohabit and run with true relays. Thus, it will be possible to create a tight grid which could for example be used for the fourth 3G operator that we wait to be created, which would be less expensive and make use of its customers Internet.
