4. What is Ad-hoc?
An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN
card, Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable
at a departmental scale for a branch or SOHO operation.
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.
