2. What is the difference between 11Mbps and 11Mbps wireless products?
What’s the benefit of 11Mbps Wireless Access Point?
The 11Mbps is made possible by the new modulation method called PBCC
developed by TI, which is different from the current CCK modulation method
for 11Mbps. The 11Mbps Wireless Access Point offers double data rate than that
of 11Mbps with 20% more distance coverage. The 11Mbps 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 11Mbps 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.
7. What is ISM band?
