10. 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.
11. 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.
12. What is DSSSWhat is FHSSAnd 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 short-duration impulse noise.
Direct-sequence spread spectrum (DSSS) generates a redundant bit pattern for
each bit to be transmitted. This bit pattern is called a chip (or chipping code). The
longer the chip is, the greater the probability that the original data can be recovered.
Even if one or more bits in the chip are damaged during transmission, statistical
techniques embedded in the radio can recover the original data without-the need for
retransmission. To an unintended receiver, DSSS appears as low power wideband
noise and is rejected (ignored) by most narrowband receivers.
