How to Use AirTight 802.11 WLAN Coverage Estimator

Draw Layout

Select the layout control (line/ellipse/rectangle) by clicking on it.	To start drawing, click on a grid intersection point with the left mouse button.

Drag the mouse without releasing mouse button as per required size and direction.	Release the mouse on or near a gridintersection point to finish drawing the desired object.
Place Access Points and Sensors

Select an Access Point type.	Drag the selected Access Point.

Move the Access Point to desired location.	Drop the Access Point.
Estimate Cost and Generate Report

Estimate costs using different price points, save the cost data.	Get personalized report containing created layout and estimated costs.

Access points You can drag and drop legacy (a, bg, abg) and 802.11n (an, bgn, abgn) access points onto the layout. The slider allows you to plan Wi-Fi coverage with a certain link speed. For 802.11n, the choice of channel width (20 MHz or 40 MHz) determines the range of link speeds available. Sensors You can protect your Wi-Fi network using a wireless intrusion prevention system (WIPS). Drag and drop WIPS sensors on the layout and plan your wireless intrusion detection and prevention coverage. Design Controls Define the dimensions of the grid area in meters or feet. You can reset the grid with the Redraw Grid button. RF Environment You can estimate the radio coverage of access points and sensors in your premises by choosing one of the pre-defined RF environments. The typical radio propagation characteristics for these environments are based on the measurements conducted by AirTight Networks. RF Controls Use the Transmit Power (mW) slider to choose the appropriate transmit power for your access points. The Dual Radio Frequency filter is useful to view either 5 GHz or 2.4 GHz coverage for dual-band (abg and abgn) access points and sensors. Line Draw lines to define the shape and dimensions of your floor. Ellipse Draw elliptical layout or structures. Rectangle Draw rectangular layout or structures. Delete Choose any object (e.g., lines, access points, sensors) on the grid and delete. Combined/Coverage/Sensor View Use the different views to focus on either access point planning or sensor planning, or to view both together. Estimate Cost Use the Cost calculator to estimate the total cost for your Wi-Fi rollout project.
