Introduction
This chapter provides an overview of the technology used by both the BayStack™
650 and the BayStack 660 wireless LAN PC cards. Both are referred to as the
“BayStack PC card.”
Information about installing and using a BayStack access point with a BayStack
PC card is available in Using the BayStack 650 Access Point and Using the
BayStack 660 Access Point. Both guides have information about planning and
installing the BayStack 600 Series Wireless LAN, including:
•BayStack 650 Wireless LAN products
Includes the BayStack 650 PC Card and the BayStack 650 Access Point
•BayStack 660 Wireless LAN products
Includes the BayStack 660 PC Card and the BayStack 660 Access Point
Product documentation for the BayStack 650 Wireless LAN products and the
BayStack 660 Wireless LAN products are available on the BayStack 600 Series
Documentation CD.
The software described in this manual for the BayStack 600 Series Wireless LANs
are available on the BayStack 600 Series Wireless LAN 802.11 Software CD.
Note: The BayStack 650 Wireless LAN products and the BayStack 660
Wireless LAN products are not interoperable.

Using the BayStack 650/660 Wireless LAN PC Card
1-2 203113-B
System Overview
The BayStack PC cards allow wireless connection for laptop computers, with a
PCMCIA slot, to an IEEE 802.11 industry standard wireless local area network
(wireless LAN). If used with the right access point (BayStack 650 Access Point or
BayStack 660 Access Point), the cards can obtain resources from any location in a
facility that is connected to an infrastructure (wired server-based) network.
If used without an access point, users can create an ad hoc network between
two or more PCs using either PC card. You can use an ad hoc network for file
sharing, print sharing, chat capabilities, and workgroup collaboration. The PC
cards employ two different technologies to make a wireless LAN connection:
•BayStack 650 PC Card
The BayStack 650 PC Card uses Frequency Hopping Spread Spectrum
(FHSS) radio frequency signals, which uses a Frequency Hopping (FH)
modulation technique to connect to a BayStack 600 Series Wireless LAN.
With FH, a radio transmits and receives on one frequency for a short period of
time and then pseudo-randomly moves to another frequency every tenth-
of-a-second. FH technology reduces susceptibility to interference from other
transmitters and noise sources in the same 2.4 GHz range since transmission
is constantly shifting from one frequency to the next. The result is better
performance, better security, and system scalability in the use of the product.
•BayStack 660 PC Card
The BayStack 660 PC Card uses Direct Sequence Spread Spectrum (DSSS)
radio frequency signals employing a DSSS modulation technique to connect
to a BayStack 600 Series Wireless LAN. DSSS takes the original data stream,
multiplies it by a spreading factor, and transmits the new altered data stream
on a contiguous group of frequencies (occupying 22 MHz of the available
spectrum). Such a group of frequencies is referred to as a DS channel.
This process provides a high-degree of security.
Note: A BayStack 650 Wireless LAN operates using an FH modulation
technique. But a BayStack 660 Wireless LAN operates using a DS modulation
technique. Since these are different modulation types, the two wireless LANs
cannot be used together.
