Template:FAQ/Questions/simultaneous voice-data-GPS over cell

Can the Goliath boards provide simultaneous voice/data/GPS over the cell network ?
Yes.


 * The GPS and GSM control functions are both connected to USB. The GSM controls are also redundantly connected to a serial port.
 * There is a USB hub controller on the Goliath board, which means that all the USB devices will be usable simultaneously by the gumstix.
 * The audio routing has a digital PCM stream from the GSM module going to a port on the gumstix motherboard, and uses AC97 to talk to the UCB1400 codec chip on the Goliath for generating analog audio (ie using mic/headset).
