Although wireless LANs, like voice systems, utilize radio signals to send data, non-digital wireless LANs are sophisticated digital systems and can be made quite secure.

- Page 5 The second type of RF modulation in the 802.11 specification is Direct Sequence Spread Spectrum. The BayStack 660 products operate within the same 2.4 MHz band as the BayStack 650 products. However, the BayStack 660 products utilize a completely different radio modulation technique than used with Frequency Hopping. This technique is called Direct Sequence.
- Page 6 time for a transmission (like we find in normal radio communications), or even discrete, narrow signals to which a data stream would “hop” (like in Frequency Hopping), the data stream in Direct Sequence systems is sent over a wide range within the band. The larger the chipping sequence, the wider the transmission band over which the original signal is spread.
