Chapter 1 - Product Overview
Features
With support for current Wireless-N, Wireless-G, and Wireless-B standards, the AirStation can transfer
data to and from all standard 2.4 GHz wireless network devices.
This device includes support for AOSS (AirStation One-touch Secure System) and WPS (Wi-Fi
Protected Setup), making connection with other wireless devices easier.
The following types of encryption are supported:
• WPA-PSK (TKIP / AES)
• WPA2-PSK (TKIP / AES)
• WEP (128-bit / 64-bit)
450 Mbps High Speed Mode
450 Mbps is the link speed when using 2 channel Wireless-N mode. It represents actual wireless
data speeds, including overhead. Because the overhead is not available for user data transfer, usable
wireless throughput will be substantially slower.
