    The BLE Technology seems promising. However, I have some queries on Bluetooth and its advanced generation BLE

    1. Which of the three is/will be cheaper? (Zigbee or Z-wave or BLE)
    2. Can devices with older Bluetooth versions (BT 2.0 or BT 2.1 or BT 3.0) communicate with a device (say iPhone 4S) installed with BLE and vice versa?
    3. I read, that the signal range of Class-I Bluetooth compatible device is 100m and the range of Class-II Bluetooth compatible device is 10 m. So, if both the devices are placed 90 m apart, can both the devices communicate now via Bluetooth (since the Class-I device doesn't fall within the range of Class-II Bluetooth signals)?
    4. What are the advantages/ disadvantages and the hazards of higher frequency ranges (The frequency range of BT and Zigbee is 2.4 GHz and Z-wave is ~908 MHz)?

    Regards
