Introduction to Wireless Technology
... Spectrum (FHSS) sends data over a set of different frequencies in a predefined pattern and is limited to a 2 Mbps data rate. Direct Sequence Spread Spectrum (DSSS) combines the data with a spreading signal, in a fashion similar to CDMA, but with a single code, and transmits at rates up to 11 Mbps. ...
