5.
There could be too much people using the same radio channel. Ask the owner of the
access point to change the channel number.
Q5: 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.
Q6: 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.

IEEE 802.11g standard
802.11g is the new IEEE standard for high-speed wireless LAN communications that provides
for up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next
mainstream wireless LAN technology for the home, office and public networks. 802.11g
defines the use of the same OFDM modulation technique specified in IEEE 802.11a for the 5
GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b. The
802.11g standard requires backward compatibility with 802.11b.
The standard specifically calls for:
A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz
frequency band, known as the extended rate PHY (ERP). The ERP adds OFDM as a
mandatory new coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48
and 54 Mbps (optional speeds). The ERP includes the modulation schemes found in
802.11b including CCK for 11 and 5.5 Mbps and Barker code modulation for 2 and 1
Mbps.
B. A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b
devices interoperate.
IEEE 802.11b standard
The IEEE 802.11b Wireless LAN standard subcommittee formulates the standard for the
industry. The objective is to enable wireless LAN hardware from different manufactures to
communicate.
IEEE 802.11 feature
The product supports the following IEEE 802.11 functions:
CSMA/CA plus Acknowledge Protocol
Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS Feature
