Appendix A Wireless LANs
Note: The AP and the wireless adapters 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 NWA are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NWA identity.
