WIPS allows you to divide a WLAN into multiple virtual security domains and add sensors (APs with
IPS enabled) to each virtual security domain. A sensor can do the following, according to the
detection rules you have defined:
• Categorizing APs in the wireless network
• Categorizing clients connected to the wireless network
• Detecting security events in the wireless network
• Dividing channels into the permitted and prohibited channels and detecting channel utilization
• Prohibiting rogue clients from accessing the wireless network
• Taking countermeasures against rogue devices
WIPS only manages Comware-based ACs.
Automatic network planning
WSM automatic network planning enables you to plan the location and number of APs by adding
virtual APs in the location topology to analyze signal coverage in the area.
RF management
WSM RF management includes network planning management and RF management.
RF management creates a heat map predicated on the radio type, transmission rates, and obstacles
such as concrete walls, windows, and metal barriers. The APs can be sorted by signal strength,
access rate, channel, or SSID. Based on location view, RF management displays the wireless signal
coverage in a room or on a floor.
With RF management, administrators can locate weak signals, low access speed, network access
failures, and other wireless signal problems. Users can adjust AP deployment, transmission rate, and
channel configurations to implement optimal and cost-effective wireless signal coverage.
Spectrum guard management
WSM spectrum analysis scans the 2.4 GHz and 5 GHz frequency bands to detect interferences and
affected channels and to generate real-time spectrum data. Operators can determine the wireless
spectrum performance and WLAN security by viewing the current interference data and real-time
spectrum data. The interferences that can be detected at the 2.4 GHz band include the following:
• Microwave ovens
• Bluetooth devices
• Fixed-frequency devices
• Video devices with fixed frequency
• Cordless phones using fixed frequency
• Microsoft Xbox
The interferences that can be detected at the 5 GHz band include cordless phones using fixed
frequency, Microsoft Xbox, and other fixed-frequency devices.
