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. 


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.  


Draw lines to define the shape and dimensions of your floor. 


Draw elliptical layout or structures.


Draw rectangular layout or structures. 


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.
