Appendix
This section provides some technological Q&A. Read the description below to know the IEEE802.11g
standard.
ü
What is the IEEE 802.11g standard?
The IEEE 802.11g Wireless LAN standard subcommittee has formulated a standard for the
industry. The objective is to enable wireless LAN hardware from different manufacturers to
communicate with each other. It is backward compatible with 802.11b.
ü
Which IEEE 802.11 features are supported?
The product supports the following IEEE 802.11 functions:
•
CSMA/CA plus Acknowledge protocol
•
Multi-Channel Roaming
•
Automatic Rate Selection
•
RTS/CTS feature
•
Fragmentation
•
Power Management
ü
What is Ad-hoc?
An Ad-hoc mode is a wireless network type, meaning a group of computers with WLAN
adapters are connected as an independent wireless LAN. It is operating without the presence of
the Access Point.
What is Infrastructure?
An Infrastructure is a wireless network type, meaning wireless stations communicate with each
other via an Access Point.
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/XP/Server 2003, or other networking operating
systems to support the printer or file sharing.
ü
Would the information be intercepted while transmitting on air?
WLAN features two-folded 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 for users to set up depending on their needs.
ü
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 the 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
