Verizon Wireless has introduced a new device that routes its cell phone traffic over a consumer’s household broadband connection, effectively creating a mini cellular service network inside the user’s home. The new box, called “Verizon Wireless Network Extender,” is designed to let Verizon Wireless customers use their cell phones at home in situations where they don’t typically have good service signals. The Verizon Wireless Network Extender acts as a small cellular base station, also known as a “femtocell.”
