ü 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.
ü What is Infrastructure

configuration. Infrastructure is applicable to enterprise scale for wireless access to
central database, or wireless application for mobile workers.
ü 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.
ü 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.
ü Can Wireless products support printer sharing
Wireless products perform the same function as LAN products. Therefore, Wireless
products can work with Netware, Windows NT/2000, or other LAN operating systems to
support printer or file sharing.
ü 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.
