Huawei AR1200 Series - WLAN Features Supported by the AR1200

An AP is a bridge that connects STAs to a LAN and converts frames exchanged between
STAs and the LAN.
l SSID
A service set identifier (SSID) identifies a service set. A STA scans all wireless networks
and selects a wireless network based on the SSID.
l Wireless medium
A wireless medium transmits frames between STAs. A WLAN system uses radios as
transmission media.
l Service set
A service set is a combination of WLAN service parameters. You can configure multiple
service sets and bind them to a radio of an AP to configure and deliver WLAN services
quickly.
l VAP
A visual access point (VAP) is a functional entity on an AP. You can create a VAP on a
radio interface of an AP by binding a service set to the radio.
1.2 WLAN Features Supported by the AR1200
The AR1200 supports Radio Frequency (RF) management, WLAN access security, and WLAN
QoS management.
RF Management
On a WLAN, the network environment changes frequently, and mobile obstacles or interference
from other radio frequencies (RFs) may affect transmission quality of radio signals.
The channels and transmit power of an AP must be adjusted to adapt to changes of the wireless
network environment. Manual adjustment increases maintenance costs; therefore, RFs are
managed by APs in a WLAN system.
The AR1200 uses radio profiles to manage RFs.
WLAN Access Security
Channels of a WLAN are open to users, and malicious users can easily intercept, modify, and
forward data of authorized users. The WLAN technology provides security policies to prevent
access from unauthorized users. You can select security policies on a WLAN based on the
security level.
The AR1200 uses security profiles to manage user access and supports four security policies:
Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2, and Wireless LAN
Authentication and Privacy Infrastructure (WAPI).
WLAN QoS Management
The WLAN QoS feature provides services of different qualities for WLAN users.
On the AR1200, you can provide QoS of WLAN services by configuring Wi-Fi multimedia
(WMM) profiles and QoS profiles.
