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, Wi-Fi congestion and intermodulation distortion.

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, intermodulation analysis and radar pattern simulation, 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.

WifiMETRIX is a new type of diagnostic tool that uses a 6 GHz radio module to simulate radar pulses and a dual-band Wi-Fi chip to monitor and troubleshoot Wi-Fi networks. It implements three important features – DFS testing (patented), AirHORN and WifiPROBE (patented). The 6 GHz radio module has been programmed to simulate radar patterns (DFS testing), and the built-in Wi-Fi chip can perform both signal generation (AirHORN) and throughput diagnostics (WifiPROBE) on each channel.

The DFS Testing function employs a 6 GHz radio module, amplifier and filters – it performs as an RF signal generator that simulates radar signal patterns. When an AP that is currently configured to use a DFS channel detects a radar signal it is then required to jump to another channel. Validation of an AP’s ability to detect and respond to radar events is the primary goal of WifiMETRIX’s DFS testing feature.

The AirHORN function is an RF signal / channel generator that transmits stable and accurate RF signals for each of the Wi-Fi channels, and aids in testing Wi-Fi antennas, RF shields and wireless networks.

The WifiPROBE function traverses each channel and measures the available transmit time. When the goal is to choose the best channel – the one with the highest available throughput – then WifiPROBE is the tool of choice.

WifiMETRIX operates in stand-alone mode and does not need to associate with an access point in order to perform its functions. It is a unique (and low-cost) device that is tailored for DFS validation, troubleshooting Wi-Fi problems and computing the best channel. The underlying IMMI Technology used by WifiPROBE is patented and the DFS Tester functionality is currently patent-pending.

RF Explorer operates both as a standalone, handheld RF spectrum analyzer and also interfaces with a PC running more sophisticated data analysis software. There are several models in the RF Explorer series of RF spectrum analyzers that span different frequency ranges — from 50 KHz up to 6100 MHz. Don’t let the price fool you — the performance of these small, affordable instruments compares favorably to more expensive and bulky test equipment.
