Appendix B: Glossary

• 802.11b - The 802.11b standard specifies a wireless product networking at 11 Mbps using direct-
sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz,
and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks.
• 802.11g - specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum
(DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz,
and backward compatibility with IEEE 802.11b devices, and WEP encryption for security.
• Ad-hoc Network - An ad-hoc network is a group of computers, each with a Wireless Adapter, connec-
ted as an independent 802.11 wireless LAN. Ad-hoc wireless computers operate on a peer-to-peer basis,
communicating directly with each other without the use of an access point. Ad-hoc mode is also referred
to as an Independent Basic Service Set (IBSS) or as peer-to-peer mode, and is useful at a departmental
scale or SOHO operation.
• DSSS - (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit pattern for all data
transmitted. This bit pattern is called a chip (or chipping code). Even if one or more bits in the chip are
damaged during transmission, statistical techniques embedded in the receiver can recover the original
data without the need of retransmission. To an unintended receiver, DSSS appears as low power wide-
band noise and is rejected (ignored) by most narrowband receivers. However, to an intended receiver (i.e.
another wireless LAN endpoint), the DSSS signal is recognized as the only valid signal, and interference is
inherently rejected (ignored).
