Device Placement on the Layout Model

¾MAC Address: Enter the MAC Address of the Radio.

¾Antenna: Select an antenna from the drop‐down list.

™Click <More> to view additional details of the antenna. The Select Antenna dialog box appears which helps you add or select the antenna in a better manner, from the list of available antennae. It is a good practice to keep the Sensor antennae to be dipole or omni‐directional, which enables the Sensor to detect and prevent attacks from any direction.

¾Orientation: Select a direction from where the antenna would receive its power. The preview reflects the antenna radiation based on the selected antenna.

¾Active Protocol: Select an active protocol from the drop‐down list. Each radio can operate on any one of the protocols.

¾Power (mW): Select a power level from the supported power values at which the Sensor operates for each selected protocol. You must keep the default values, which are based on the maximum transmit power for the protocol as permitted by the regulatory agencies in the countries for which you are doing the WLAN planning. (Example: FCC in the United States). Refer to Appendix D: Glossary of Terms for more details on regulatory domain compliance.

¾Waterfall Curve: Select a waterfall curve from the drop‐down list of available waterfall curves for the selected protocol.

¾Advanced Parameters: Click to set the advance 802.11n parameters. This is available only if you have selected the 802.11n protocol.

Click <Save> to save the changes. Alternately, click <Cancel> to discard the changes.

7.7Viewing Signal Strength

Planner enables you to view the signal strength of all the devices placed on the floor map across a layout. Use either of the following to view the signal strength:

•Click from the Toolbar

•Right‐click anywhere on the floor map and select View signal Strength

The View Signal Strength screen appears.Figure 121. Viewing Signal Strength

The screen displays the signal strength values and device details such as the Device Name, Radio ID, Active Protocol, SSID, Signal Strength, and Link Speed of the devices on the floor map. The Signal Strength and Link Speed values change as you move the cursor across the floor map.

7.8Statistics

Statistics gives the percentage (%) area under specific RF coverage as compared to the total layout area. Click on the Toolbar to invoke Statistics.

RF coverage for statistical analysis includes:

•Access Point Views: Coverage, Link Speed, and Channel Interference

•Sensor Views: Sensor Detection Only, Sensor Prevention Only, and Sensor Redundancy

Note: To view the Statistics for the Sensor Views, switch to the Sensor View group and click the Statistics icon.
