Wake on Wan is an application written by XDA-Developers user petititi, which allows remote powering on of your computer over WiFi or GRPS/3G. The application uses the Wake-On-Lan magic packet technology, which allows a packet to be sent to your network card while the computer is turned off, and powers the computer on. You can read more about the technology here at Wikipedia.

The application also uses the Sense SDK, which allows a beautiful interface to use to wake up your computer.
