Mobile Marketing: The History of Mobile Network Technologies - FemtoCell
FemtoCell is a technology that is used indoors to boost indoor mobile handset signals by converting a wired broadband signal into a radio signal that mobile phones can pick up. AT&T, Sprint, and Verizon already offer FemtoCell base stations for subscribers' homes, and it is also being deployed in some commercial locations. This type of technology will likely be important for improving access to mobile marketing messages to your demographic when they are inside and mobile signals are weaker.
