Setting up a wireless network is pretty easy (for most of us), but Apple wants to simplify the process even further by putting RFID transceivers into wireless base stations, like the AirPort Express or AirPort Extreme. All network info (like encryption keys and SSID info) would be stored in the base station. Devices that you want to connect to your network would be fitted with RFID tags, so when the two come face-to-face (the device and your base station), RFID info can be read/written to the tag without having to configure anything. As an example, the patent mentions an Apple Wi-Fi remote...
which could be configured by "bringing it into proximity with the computer or network base station." In the long run, this will make networking devices easy enough for my Luddite relatives to do, which is good news for people who get weak in the knees at the thought of networking.
