VisiWave Site Survey 4.0

A new, major release of VisiWave Site Survey is available right now to assist you in building and maintaining your wireless networks. VisiWave has always been a powerful, yet simple, WiFi site survey tool. Now it's even more powerful, but still straightforward to use.

Predict Access Point Coverage

Answer "what-if" questions: After performing a wireless survey—even while sitting back at your desk—you can virtually move an access point and have VisiWave predict what the new coverage heat map will be:



A heat map that predicts the coverage if the AP was relocated

VisiWave gives you the ability to see what coverage would be like if you moved an existing AP to a new location. VisiWave models the coverage based on existing measurements and creates a heat map that predicts what coverage would be like with an AP in the new location.

New Chanalyzer Integration

Add a second dimension to your spectrum analysis: With VisiWave you've always been able to create an interference heat map. Or you could use a spectrum analyzer to see the interference at a specific location. Now for the first time, you can map where the interference is occurring and also replay the spectrum data in a real spectrum analyzer. Collect data once then analyze it any time:

Google Earth Reports

Embed yourself inside your building or city-wide site survey results. Instead of viewing static, flat survey results, use VisiWave along with Google Earth to interactively visualize your wireless coverage as 3D models overlaid on the earth's surface. Reveal patterns and details of your Wi-Fi network that simply can't be seen in a PDF report:

All New Features in v4.0 of VisiWave

Support for creating reports in Google Earth has been completely re-done. Google Earth reports now sit right next to PDF and HTML as an output type. Just create a report like you always do and then select Google Earth as the report type.

VisiWave can now show you the predicted coverage of an access point by just virtually moving that AP to a new location on the map. You can propose a new location for any AP Marker that is linked to an actual AP. VisiWave then predicts the coverage of that AP in the new location.

Now you get the best of both worlds when it comes to analyzing your area's interference. VisiWave shows you on a map where the interference is happening and Chanalyzer Pro allows you to see the specifics of the type of interference that was recorded during the survey.

After doing a survey with VisiWave where you collected spectrum data using a Wi-Spy device, you can now view the interference within Chanalyzer Pro. VisiWave automatically launches Chanalyzer and tells it to load the spectrum data collected during the survey. You then use all the normal, powerful features of Chanalyzer to examine the spectrum data.

Note, versions of Chanalyzer prior to v5 may not properly load the spectrum data. If this happens, you will need to upgrade to Chanalyzer 5 or later.

802.11ac is now supported. Just plug in a wireless adapter that supports the 11ac standard and VisiWave will use it to record Wi-Fi survey data.

You now have two color scheme choices: Blended and Distinct. Blended is the new scheme that behaves more like the typical temperature heatmaps that are used for weather forecasts. With this method, you still pick three base colors, but VisiWave now smoothly transitions from one color to the next by blending the two neighboring colors. Also, by default, the three base colors are red, yellow, and blue where red indicates strongest and blue indicates weakest. This is also more like typical temperature heatmaps.

The image file used as the floor plan image is now stored within the survey data file. So now you can move a survey file around without having to also move the image file along with it. This also makes it easier to share a survey file with others.

VisiWave can now directly use floor plan images stored as PDF documents. The entire first page of the PDF is used as the background for your survey area.

Surveys that collect a large number of data points and a large number of access points are now processed much faster. VisiWave can easily handle a survey that collects thousands of data points and that contains thousands of unique access points.

Up until now, your survey maps had to have 'north' pointing to the top of the map or they wouldn't work with Google Earth or GPS data collection. Now you use a map with any orientation. You just have to tell VisiWave which direction is north by using the new "Set North" feature.

Now a minimum signal strength (or SNR) can be set for heatmap graphs. Areas that fall below this minimum value are not colored in.

When hovering your mouse pointer over a data point, the value shown is the strongest signal strength from the set of APs selected in the AP List on the right. Previous versions of VisiWave didn't take the AP List into account when picking the value to show.

Download Free Evaluation

If you aren't currently using VisiWave, it's time to take a second look. The full-featured evaluation version is a simple download and install. Download the evaluation version now.

Upgrade to Version 4.0

If you already own VisiWave, upgrade to the latest version. It's a low-cost upgrade and more than worth it.
