Nextel's phones include a feature it calls Direct Connect, which lets users push a button, like the CB radios of the '70s, and talk instantly walkie-talkie style with selected users who have similar phones.
The ARIS connects to a home network at the push of a button using Wi-Fi Protected Setup (WPS), which is built into most current wireless routers, or a simple on-board setup sequence when WPS is not available.
