Nuts About Nets has been developing wireless diagnostic tools and software since 2006. Our focus is low-cost, easy-to-use tools that professionals and non-professionals alike can use to solve real-world problems related to RF interference and intermodulation distortion. The tools come in two hardware form-factors — USB dongle or handheld. A wireless USB dongle attaches to a Windows PC running diagnostic software, whereas a handheld instrument can operate standalone (or also connect to a Windows PC).

Our track record speaks for itself — both in the width and breadth of new, innovative products we’ve developed. With patents for Wi-Fi channel optimization and intermodulation analysis, we’ve demonstrated an ability to approach old problems from new perspectives.

Whether your objective is to troubleshoot a problem with a Wi-Fi network, coordinate wireless transmitters and monitor frequencies for a live event, test your RC gear, detect sources of RF interference or rogue transmitters, or you simply require a general-purpose instrument to measure RF transmissions across a frequency spectrum, then check-out our products to see how they can help solve your wireless needs in today’s increasingly crowded and unpredictable RF spectrum.

Introducing WifiBuilder

The Industry’s First Diagnostic And Production Wi-Fi Access Point


WifiBuilder is the industry’s first diagnostic and production Wi-Fi access point. A new type of wireless network tool that excels at determining your wireless network’s best channel. WifiBuilder is both a diagnostic tool AND a high-end, dual-band, 802.11N access point. Use it in diagnostic mode for troubleshooting and detecting RF interference that cripples the performance of your Wi-Fi network (using IMMI technology it computes which channel has the greatest available bandwidth). Or use it in production mode, configure the WifiBuilder access point to use the best channel for optimal performance and leave it in place — for use as your normal AP.

Profiler24x is a Wi-Fi diagnostic tool used for installing, troubleshooting and monitoring 802.11 wireless networks in the 2.4x GHz band. It is unique in its use of an access point (WifiBuilder) in performing channel analysis. Employing patent-pending IMMI (Indirect Measurement of Microwave Interference) technology Profiler24x provides unprecedented visibility into the performance of a wireless network. The information collected and displayed by Profiler24x helps to simplify troubleshooting of interference-related problems and predicts bandwidth performance for each 802.11 channel.


PC Magazine Best Of 2011 -- WifiBuilder

PC Magazine announces that WifiBuilder has won the seventh annual PCMag.com Best of the Year 2011 Award in the category of Network Software.


PC Magazine Review of WifiBuilder Diagnostic AP

WifiBuilder received a great review from PC Magazine — 4.5 stars and an Editor’s Choice award.

WifiBuilder Diagnostic and Production Access Point

Why Use WifiBuilder ?

Running a custom Linux kernel, the WifiBuilder AP communicates with diagnostic applications that are run from your Windows desktop or laptop machine. These diagnostic applications are used for installing, troubleshooting and monitoring 802.11 wireless networks. That is, in addition to being used as your normal AP for wireless network communication, WifiBuilder is designed to be used as a diagnostic tool — performing data acquisition and communicating with a Windows application that analyzes the results and displays them using graphical charts. When the WifiBuilder AP is left in-place as your normal AP then its diagnostic capabilities are always available when the need arises.

Introducing Intermod Assist

Intermodulation Calculator and Frequency Coordination Software


Introducing the latest, low-cost development in RF intermodulation analysis and frequency coordination — Intermod Assist. Intermod Assist is a new, ground-breaking software tool specifically designed for the wireless, professional audio and video industries. Its computational engine rapidly generates frequency sets of intermodulation distortion-free radio frequencies, applying user-defined signal bandwidths and channel spacing. These frequency sets can be used to coordinate transmitter frequencies where the goal is to assign the most reliable channels to your wireless audio and video gear — that is, channels free of intermodulation interference.


Pro Audio White Space Finder / RF Spectrum Analyzer

Why Use Intermod Assist ?


In the wireless audio industry, RF interference and intermodulation distortion have become major concerns — the number and variety of new and different wireless devices that operate in the UHF band can wreck havoc when it comes to configuring wireless audio gear.  In the shrinking frequency space allotted for wireless audio equipment it has become a true challenge to assign interference-free channels to wireless audio equipment. Intermod Assist is an invaluable tool that can be used to facilitate frequency coordination and channel assignments in the most complex RF environments.  Intermod Assist saves valuable setup time by computing the most reliable frequencies — free of interference from intermodulation products.
