2. What is the difference between 54Mbps and 11Mbps wireless products?
What’s the benefit of 54Mbps Wireless Access Point?
The 54Mbps is made possible by the new modulation method called OFDM,
which is different from the current CCK modulation method for 11Mbps. The
54Mbps wireless products also operate in the 2.4GHz ISM band and they are
backward compatible with 11Mbps wireless products.
3. What is Roaming?
Roaming is the ability of portable computers, e.g., Packet PC and notebook, to
have consistent and continuous data transmission/reception throughout an
area covered by more than one Wireless Access Point. In order to achieve
seamless connectivity, all the wireless clients and Access Points must be set to
use the same SSID. When a user walked out of the coverage area of one AP
into another, the wireless client network device will automatically reestablish
connection with the new AP.
4. What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking devices, e.g. a network adapter, that
allows the network to identify it at the hardware level. Unlike IP addresses,
which can be changed or dynamically assigned by the network, the MAC
address of a networking device is permanent.
5. What is WEP?
Wired Equivalent Privacy (WEP) is a type of data encryption mechanism
described in the IEEE 802.11 standard. The 54Mbps Wireless Access Point
supports 64/128/256 bit shared key for WEP.
6. Would the information be transmitted securely in the air?
WLAN offers two layers of protection for security. First layer is on the hardware
level. As with Direct Sequence Spread Spectrum (DSSS) technology, it has
the inherent security feature of scrambling. Second of all, on the software level,
the security control is made possible by Wired Equivalent Privacy (WEP) for
access control.
