One of the tooted selling points of FemtoCells is the enhanced user experience indoors. There is no doubt that in terms of radio coverage the FemtoCell will enable a more uniform and better RF signal indoors.
The story does not end there however. The underlying concept of "convergence" with FemtoCells will give content personalisation and customisation a whole new dimension. In addition to simple signal radiation, a FemtoCell router serving 2-3 mobiles can also perform a whole bunch of other tasks on behalf of users. This is a new uncharted territory with a poetic license to daydream. A variant of social networking can also emerge if it is embraced by the new breed of "converged" operators.
With Google putting effort on mobile content search, the FemtoCell era will be a very exciting and interesting period and one should expect interest in this technology to extend beyond the circle of traditional mobile operators.
