The benefit with sticking with Bluetooth, ZigBee or Wi-Fi is that you are not really locked into a vendor. Agreed, Tony. We would support ZigBee protocol for sure. We might also support LIN. Since we are creating wired LIN networks, we'd like a low-cost wireless bridge for industrial units (sensors, etc.) and we're thinking of just continuing the RS-485 signaling into the RF medium. But for CF modules, we'd be running ZigBee. There could be multiple products: - very low power, low speed (possibly 315/433 MHz) - higher power, higher speed (900 MHz) We'd be going "non-standard" if we support 1 MegaBaud data rates, since ZigBee is limited to 250kbps I believe. But you could also use the same unit at lower rates too for compatability.
