WiFi is an incredibly useful communication protocol that is widely used. In fact, it’s the de facto standard used to create wireless networks in homes, businesses, public spaces etc.
However, it’s not uncommon for signal strength to degrade due to a variety of factors, including distance from the access point, obstacles, competing WiFi signals, and appliances.
WiFi heat map software can create an accurate map of signal strength during a site survey, producing a graphical representation of hot, cold, and dead areas.
Many professionals responsible for installing and maintaining WiFi networks will find a lot of value to WiFi heat map software in order to implement an environment with the best wireless coverage and performance possible.
I have done my research and curated the top heat map tools in the market in the list below. Some of them are even free so they can benefit a person who wants something simple for smaller environments.
Keep in mind though that for a large scale enterprise site survey you will need professional gear (wifi hardware with specialized interface cards etc) so that you can get the best results.
Table of Contents
Ekahau HeatMapper
The Ekahau Heatmapper is a small package that only takes a single minute to install. Being free also makes it well worth a look for anyone who is having WiFi coverage issues.
It comes in two versions, the free HeatMapper one which is for home and SOHO use and also the Ekahau Pro version which is a commercial solution for Enterprise use.
Even though it only works on Windows, it can easily be installed on a laptop for best portability while moving around the area.
It will find all available access points in the area, and supports typical WiFi standards, including 802.11n and a/b/g.
After you install the tool on a Windows laptop and start the app, you will need to walk around in the house or office space (i.e site-surveying) so that the software will pick up all the available wireless signals and access points in the area.
After the site-survey (limited to 15 minutes of survey) you will get a heat-map with colors and signal strength numbers (in dBm) of the area. This will help you to adjust the location of access points or wifi routers, change channels for lowering interference etc.
As we mentioned above, if you need something more powerful for a commercial enterprise, it’s worth looking at the big brother of this software – Ekahau Pro. This includes many more analysis and troubleshooting features. You will need also to get some professional hardware gear for big scale surveys of large buildings.
Price
- HeatMapper: Free
- Ekahau Pro: Between $4500 to $6000
NetSpot
One of the best things about NetSpot is that you get a professional level WiFi analysis tool for free, with the option to upgrade to the enterprise version for even more advanced capabilities.
It works on both Mac OS as well as on Windows (7,8,10), and provides a huge amount of information in a small package.
NetSpot will help you to work out where the hotspots and coldspots are, as well as the dead zones. It will help anyone to put together the optimum WiFi network for home, SOHO or larger environments.
When you fire up the free Netspot app, you will start getting information such as:
Free Process Mapping Software For Mac
- SSID and MAC address of the wifi routers.
- A graphical map showing a history of the signal strength.
- Current signal strength in dBm
- Channel of signals, wireless band, width of frequency channel, protocol used etc
- And much more
So, just like the previous tool in this list, you can just walk around in the area with your laptop and start surveying the facility to get a heat map of the wireless signals. This will help you re-arrange access points if needed or change channels for better coverage.
Price
Both free and paid versions are available.
The paid Enterprise version is priced at $499 for up to 10 users.
SolarWinds WiFi Heat Map
SolarWinds may not be free, but what it does is quite amazing. It quickly produces a WiFi heat map that will update in real time. This allows you to see any dead spots and their possible causes.
The other great thing about SolarWinds is that the maps it produces are attractive, intuitive, and very easy to understand. This makes it one of the easiest to understand WiFi heat mapping packages around.
It even discovers and maps all connected client devices within 3 meters. This can help in resolving problems with users that complain about their wifi reception. You can find out if the problem is their location or their client device.
By importing a background image of the office or room plan, you then drag and drop the wireless points on the map (routers, access points etc) to create the heat map.
It even supports creation of network diagrams using Microsoft Visio.
Price:
The wifi heat map functionality is offered under Solarwinds NPM (Network Performance Monitor) which is priced at $2,995 (starting price).

Making maps for orienteering can be an expensive business. Being a niche market, orienteering mapping software such OCAD can prove prohibitively pricy for individuals looking to get started in mapping, plus you are restricted to being a Windows user. Going down the vector graphics route using free plugins for mainstream drawing tools, such as MapStudio for Adobe Illustrator, opens up mapping to Mac and Windows users but again proves to be expensive.
Now however we've learnt of a new option for making orienteering maps, using completely free software, available across Mac, Windows and Linux platforms. By using Inkscape, an open source cross platform vector graphics editor, coupled with an orienteering specific set of extensions - O-scape, you can now draw orienteering maps for free.
If you're used to vector drawing then you'll find Inkscape and O-Scape easy to pick up. For newcovers, vector drawing can be quite a steep learning curve, but perseverence is worthwhile and Inkscape does seem to be very intuitive to use compared to other vector drawing software.
We got in touch with Jon Eaton (WCOC), the developer of the O-scape extensions to find out more about the project.

Nopesport: What prompted your development of the O-scape extensions?
Jon Eaton: Last Christmas I spent a while searching the internet for free software that could provide a platform for the production of Orienteering maps. The search proved fruitful when I discovered Inkscape.
Inkscape is a cross-platform Open Source vector graphics editor distributed under a free software licence and can be run on Linux, Windows & Mac OSX. Inkscape has capabilities similar to Adobe Illustrator and uses the W3C standard Scalable Vector Graphics (SVG) file format. Inkscape has a deceptively simple and streamlined interface while supporting many advanced features making it very easy to edit nodes, perform complex path operations, trace bitmaps and much more. Inkscape is under active development, with new features being added regularly by a thriving user and developer community using open, community-oriented development. More information on Inkscape can be found on the Inkscape website.
Inkscape has been designed to accept extensions written in a number of programming languages and includes interpreters for Ruby, Perl and the most commonly used language for writing Inkscape extensions, Python.
I have written a set of Python extensions, the O-scape extensions that, together with the innate capabilities of Inkscape, enable the full symbol set of ISOM:2000, ISSOM:2007 and the new ISMTBOM:2010 to be created. The O-scape extensions are now available on SourceForge.net at: sourceforge.net/projects/o-scape/files/.
Nopesport: What is the benefit of using Inkscape and the O-scape extensions?
Jon: Being FREE, Inkscape and the O-scape extensions will hopefully enable individuals and small clubs to create maps where they were previously unable to afford the software required. Also, this could provide the mapping tool to enable orienteering to spread into more areas and countries.
Nopesport: What are your future plans for O-scape?
Jon: Currently Inkscape and the O-scape extensions cannot generate pictorial control description tables although a full set of the control description symbols is available. This is a gap that I hope to fill in a future update. Inkscape can, though, output high resolution PNG files, providing compatibility with Condes and Purple Pen.
Simple instructions are currently provided to get people started using Inkscape and the O-scape extensions. It is my intention to a write a comprehensive manual to describe the best ways of using the O-scape extensions with Inkscape.
Other areas where I'm looking to make developments include a routine for generating random dot patterns to automatically produce regions of symbol 117 Broken Ground and 210 Stony Ground and the ability to import Ocad files into Inkscape (if at all possible).
This is the first release of the O-scape extensions and is, as such, untested in the real world. Therefore, I would appreciate feedback of any comments that you may have and that may improve the operation and performance of the extensions.
If you want to get involved in the project, find out more about O-scape on SourceForge or get in touch / send feedback at: o_scape@btinternet.com or discuss this on the Nopesport forums.
So, now we've got free map drawing through O-scape, you can now use entirely free software from start to finish of putting on an event. Draw the map using O-scape, use Purple Pen to plan your courses, then use Ór to manage entries and results on the day.
While we believe there is orienteering software out there that is worth paying for, free options help open up the sport to individuals and small clubs who can't afford the cost of software. This hopefully will also force the developers of commercial software to stay on top of their game in improving their work and meeting the needs of their userbase, before they opt for the free route.
