Unlike WiFi, this technology is carrier-specific. It will only work with Verizon. WiFi is something you already have at home, and which is already available in hundreds of millions of locations worldwide. WiFi can also be generated easily in those hotel rooms around the world. With WiFi, all services also work (including all data), not just circuit-switched voice. For these reasons, I think T-Mobile USA's solution of using dual-mode WiFi handsets is a lot smarter. Just imagine if you've got several carriers in your household and/or business -- Sprint, AT&T, Verizon, T-Mobile -- why have several Femtocells (one per carrier) when it ought to be enough to just simply have WiFi? And if you have a large space -- larger than 5,000 square feet -- you need multiple Femtocells for each carrier. In contrast, T-Mobile USA guarantees flawless in-building coverage virtually for free, thanks to WiFi.
