iPhone 3G users stuck in an AT&T dead zone at home or at work will soon be able to plug in a device that provides a strong local signal for up to 10 phones and four simultaneous voice or data connections via a connection to broadband Internet.
Price and availability haven't yet been set for the appliance, which AT&T calls the 3G MicroCell. The CDMA industry usually refers to local area, consumer cellular base stations as a "femtocell," suggesting a smaller version of the "picocell," an industry term for a cellular base station installed to extend the signal of standard "Node B" antennas of cellular networks. Apple has installed commercial GSM picocells with 3G base stations within its retail stores that work in parallel with WiFi base stations to give the locations both WiFi and 3G cellular signals.
