5. What 

is 

Ad-hoc

 

An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN adapter, 

Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a 

departmental scale for a branch or SOHO operation. 

 

6.  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. 

 

7.  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. 

 

8.  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. 

 

9.  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. 

 

10. 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. 

 

11.  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. 

 

12.  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. 

 

13.  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
