Note: The wireless devices MUST use the same preamble mode in order to
communicate.
IEEE 802.11g Wireless LAN
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an
IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point
(and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has
several intermediate rate steps between the maximum and minimum data rates.
The IEEE 802.11g data rate and modulation are as follows:

Wireless Security Overview
Wireless security is vital to your network to protect wireless communication
between wireless clients, access points and the wired network.
Wireless security methods available on the NXC are data encryption, wireless
client authentication, restricting access by device MAC address and hiding the NXC
identity.
The following figure shows the relative effectiveness of these wireless security
methods available on your NXC.
