6. What is BSS ID?
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be
configured with the same BSS ID.
7. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared
key algorithm, as described in the IEEE 802 .11 standard.
8. What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP
security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i
WLAN security standard, and the specification might be officially released by early
2003.
9. What is AES?
AES (Advanced Encryption Standard), a chip-based security, has been developed to
ensure the highest degree of security and authenticity for digital information,
wherever and however communicated or stored, while making more efficient use of
hardware and/or software than previous encryption standards. It is also included in
IEEE 802.11i standard. Compare with AES, TKIP is a temporary protocol for replacing
WEP security until manufacturers implement AES at the hardware level.
10. Can Wireless products support printer sharing?
Wireless products perform the same function as LAN products. Therefore, Wireless
products can work with Netware, Windows 2000, or other LAN operating systems to
support printer or file sharing.
11. Would the information be intercepted while transmitting on air?
WLAN features two-fold protection in security. On the hardware side, as with Direct
Sequence Spread Spectrum technology, it has the inherent security feature of
scrambling. On the software side, WLAN series offer the encryption function (WEP)
to enhance security and Access Control. Users can set it up depending upon their
needs.
12. What is DSSS? What is FHSS? And what are their differences?
Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly
synchronized, the net effect is to maintain a single logical channel. To an unintended
receiver, FHSS appears to be short-duration impulse noise. Direct-sequence
spread-spectrum (DSSS) generates a redundant bit pattern for each bit to be
transmitted. This bit pattern is called a chip (or chipping code). The longer the chip is,
the greater the probability that the original data can be recovered. Even if one or
more bits in the chip are damaged during transmission, statistical techniques
embedded in the radio can recover the original data without-the need for
retransmission. To an unintended receiver, DSSS appears as low power wideband
noise and is rejected (ignored) by most narrowband receivers.
