5. What is Infrastructure?
An integrated wireless and wireless and wired LAN is called an Infrastructure
configuration. Infrastructure is applicable to enterprise scale for wireless access
to central database, or wireless application for mobile workers.
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
