manufactures to communicate.
2. What does IEEE 802.11 feature support
?
The product supports the following IEEE 802.11 functions:
l
CSMA/CA plus Acknowledge Protocol
l
Multi -Channel Roaming
l
Automatic Rate Selection
l
RTS/CTS Feature
l
Fragmentation
l
Power Management
3. What is Ad-hoc
?
An Ad-hoc integrated wireless LAN is a group of computers, each has a W ireless LAN

8. 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
