An apparatus and method for WGIO phase modulation are described. In one embodiment, the method includes the receipt of a high-speed data stream, encoded according to an 8b/10b code. Once received, a symbol rate of the data stream is reduced by a predetermined amount. Finally, once the symbol rate is reduced, a square wave carrier is phase modulated, using the reduced data rate data stream to generate a WGIO signal having double side band spectrum distributed either side of the square wave carrier. Accordingly, in one embodiment, a 3GIO signal may be phase modulated in order to fall within a spectrum that is not currently occupied by a wireless protocol, including, for example, Wireless Local Area Network (WLAN), Wireless Wide Area Networks (WWAN), global positioning systems (GPS), or the like in order to prevent interference therebetween.
