◉ The ratio of the chipping code to data bits for a direct sequence
spread spectrum (DSSS) signal is called which of the following
Answer: Processing Gain
◉ Which component of frequency hopping spread spectrum (FHSS)
system creates more overhead than any similiar component in a
direct sequence spread spectrum (DSSS) system
Answer: the interframe spacing
◉ How does spread spectrum tech reduce the probability of signal
jamming
Answer: By transmitting over a wide frequency spectrum
◉ Although there are many different implementations of spread
spectrum tech, what are the only types specified by the FCC in the
Codes of Federal Regulation (CFR), volume 47, part 15
Answer: Direct Sequencing Spread Spectrum (DSSS) and Frequency
Hopping Spread Spectrum (FHSS)
, ◉ Why is Direct Sequencing Spread Spectrum (DSSS) the most
widely known and the most used of the spread spectrum types
Answer: Its ease of implementation and high data rates
◉ What is the width of Direct Sequence Spread Spectrum (DSSS)
channels and how far apart are their center frequencies spaced
Answer: 22 MHz and 5 MHz
◉ What Wireless Local Area Network (WLAN) device can be
described as a half-duplex device with intelligence equivalent to that
of a sophisticated Ethernet switch
Answer: an Access Point (AP)
◉ What are some common methods used to configure and manage
access points (AP)
Answer: Telnet/ssh (Secure Shell), USB, and a built in web server for
browser access
◉ What is a half-duplex device that is only capable of (OSI) reference
model Layer 2 connectivity
Answer: A wireless bridge
◉ Which statement best describes protocol filtering that has been
implemented in a wireless bridge
