TOPIC

    What's the difference between DSSS and FHSS?


DISCUSSION

    Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS) are two different technologies in the IEEE 802.11 specification. They are incompatible with each other.

    Frequency Hopping technology is older and is limited by government regulation to 2 megabits per second.

    Direct Sequence technology is becoming more widespread and supports data rates of up to 11 megabits per second. Apple uses DSSS technology because it is equivalent to Ethernet data rates.

    Note : Wireless internet access requires AirPort Card, AirPort Base Station, and Internet Access (fees may apply). Some ISPs are not currently compatible with AirPort, including America Online. Range may vary with site conditions.
