Configuration

24 Mbps, 18 Mbps, and 12 Mbps. As a mobile client travels away from an 802.11a
Access Point, the Access Point automatically decreases the data rate in order to
maintain a usable radio connection with the client.
For example, in an Infrastructure network that is using 2X mode, a client that is close
to an Access Point may operate at 108 Mbps, but a client that is far away from the
Access Point may operate at 12 Mbps. By default, a Skyline 802.11a Access Point
automatically adjusts its transmit rate depending on the mode of operation (802.11a-
compliant or 2X). However, you can also manually configure a specific send rate that
the Access Point will use.
WEP Security
The IEEE 802.11a standard specifies an optional encryption feature, known as Wired
Equivalent Privacy or WEP, that is designed to provide a wireless LAN with a security
level equal to what is found on a wired Ethernet network. WEP encrypts the data
portion of each packet exchanged on the 802.11a network using a 64-bit, 128-bit, or
152-bit encryption key (also known as a WEP Key). In addition, Skyline 802.11a devices
use WEP with Shared Key Authentication to prevent unauthorized devices from
associating with an 802.11a network.
When WEP is enabled, two 802.11a devices must have the same WEP Keys and both
devices must be configured to support WEP in order to communicate. If one device is
configured to use WEP for Authentication and Encryption but a second device is not,
then the two devices will not communicate, even if both devices have the same WEP
Keys.
Dynamic WEP Key Entry
When you select a Key Size, the appropriate WEP Key entry screen will open
automatically. The Skyline Access Point can support up to four WEP Keys (all four Keys
must have the same Key Size).
For 64-bit encryption, a WEP Key is 10 hexadecimal digits (0-9 and A-F); for 128-bit
encryption, a WEP Key is 26 hexadecimal digits (0-9 and A-F); and for 152-bit
encryption, a WEP Key is 32 hexadecimal digits (0-9 and A-F).
When WEP is enabled, Proxim recommends that you configure all 802.11a devices in
the Extended Service Set with the same WEP Keys in the same order (but the devices
do not need to use the same default Key).
Enable Repeat
The Skyline 802.11a Access Point can repeat packets between 802.11a clients that are
associated with it. If your network requires that 802.11a clients communicate with
each other, then enable the Access Point's Repeating parameter. Otherwise, set
Repeating to disabled if you want to prevent 802.11a wireless clients from
communicating with each other.
