Wi-Fi Diagnostics & Troubleshooting

Troubleshoot and Solve Wi-Fi Problems Related To RF Interference

Nuts About Nets is a leading innovator of low-cost, PC-based, WiFi diagnostic tools used for installing, optimizing and troubleshooting 802.11 (WiFi) wireless networks. Organizations, small companies, technicians and individuals worldwide rely on our products and solutions for solving wireless problems associated with RF interference.

From the introduction of the AirSleuth and Invisible Waves series of RF spectrum analyzers to the unique AirHORN series of channel / signal generators, and now the recent addition of IMMI technology and WifiEagle channel analyzers and WifiBuilder diagnostic access points, Nuts About Nets has demonstrated a track record of creative solutions for helping solve interference-related wireless problems.

IMMI Technology & Wi-Fi Channel Analysis

Optimize Performance By Using The Best Wi-Fi Channel

When troubleshooting an 802.11 network it is not possible to predict how it will behave when you are armed solely with RF measurements. This is why we focus on performance metrics and IMMI (Indirect Measurement of Microwave Interference) technology -- because they more accurately predict how your wireless network will actually perform.

Though RF spectrum analysis remains a popular tool for troubleshooting interference-related problems, IMMI technology holds greater promise since it excels at computing the best Wi-Fi channel -- that is, the channel with the greatest available bandwidth and least affected by RF interference from other wireless devices.

RF Channel And Signal Generators

Control The Source of Transmissions And Generate Wireless Traffic

AirHORN is a unique, PC-based product that aids in testing Wi-Fi antennas, RF shields and wireless networks. It is an RF signal generator that covers the 2.4x and 5.x GHz ISM bands and was designed for microwave and RF applications. AirHORN transmits stable and accurate RF signals for each of the Wi-Fi (802.11) channels and is ideal for research and development of antenna design.

A signal generation system is key to any test system – AirHORN can be used for rapid evaluation of receiver performances. Combined with an RF spectrum analyzer, you now have the tools to locate "dead spots" in any locale where a Wi-Fi network is installed.

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.

Pro Audio White Space Finder is a “game-changer”

The industry’s first product that includes both realtime RF spectrum analysis and intermodulation analysis

Precise, wideband RF spectrum scanning, visualization and channel coordination of the RF environment

In a hostile RF environment why leave your wireless planning to chance ?!   Take the guess work out of configuring your wireless audio gear — Pro Audio White Space Finder / RF Spectrum Analyzer enables you to choose the optimal channel assignments — free from RF interference and intermodulation distortion. The PAWS4400 analyzer offers detailed RF spectrum scans using easy to view, graphical displays, along with interference-free channel assignments. Real-time RF spectrum analysis combined with our intermodulation distortion (IMD) module delivers optimal channel assignments for even the most demanding RF environments.

Pro Audio White Space Finder / RF Spectrum Analyzer


PAWS4400 Was Designed With These Goals In Mind:


• Combine RF spectrum analysis and intermodulation analysis in a single tool.
• Automatic charting of open white spaces (RF frequencies) in a real-time RF environment.
• Graphical UI that is easy to use; lays-out the relevant data in a clear, concise way.
• The UI is tablet-PC friendly.
• Fast data acquisition, display, and channel assignments.
• Sets up the RF spectrum analyzer with proper default settings for span, RBW, VBW, image suppression, scaling, and sensitivity with minimal user input. This allows users with little to no experience with spectrum analyzers to get right to work.
• User-definable threshold for open white space.
• Sensitive and accurate measurements.

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.
