Multi-point Bridge:
Connects more than two independent Ethernet LAN networks or computers wirelessly.
5. 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.
6. 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.
7. 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 bit shared key
for WEP.
8. 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.
9. What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed
use in the ISM (Industrial, Scientific and Medical) band. The 2.4GHz unlicensed ISM band
is available worldwide, which presents the opportunity for the global market of 802.11b
high speed wireless products.
