We live in an imperfect world. In a perfect world, all countries would share the same set of frequencies that can be used by Wi-Fi devices. In fact, in a perfect world, there would be no countries in the first place. In the real world, each country has its own regulatory body that permits the utilization of certain frequencies for this or that purpose.Continue reading “On the 6 GHz Wi-Fi Band and Tin Foil Hats”
At TamoSoft, we’ve always strived to offer the same set of features in TamoGraph for Windows and macOS. However, there has been one area in which the macOS version lagged behind the Windows version: TamoGraph for macOS couldn’t use external USB adapters to capture Wi-Fi data. Today, with the release of TamoGraph 7.0.137, this limitation has gone.Continue reading “Using an External Adapter Is Now Supported in TamoGraph Site Survey for macOS”
Modern Wi-Fi networks use beamforming, multiple spatial streams, and higher order modulation, such as 256-QAM and 1024-QAM.Continue reading “Packet Capture Challenges in Modern Wi-Fi Networks”
In a previous blog post, All You Wanted to Know About Testing Wi-Fi Adapters, But Were Afraid to Ask, I promised to blog about Wi-Fi data collection. Well, that day has come. A recent Twitter discussion convinced me that shedding some light on this topic could be beneficial for the Wi-Fi community, because many people have only vague ideas about what’s going on under the hoods of their favorite sniffer or site survey applications. “Is that really important?” you may ask. Yes, guys, it’s very important, and yes, you should care. I’ll try to explain why. Continue reading “How Applications Collect Wi-Fi Data and Why You Should Care”
It’s been a while since we released TamoGraph 5.0, but we’re finally ready to deliver the next version of TamoGraph for Windows and macOS, a software tool for Wi-Fi network planning and site surveys. We’re putting the finishing touches on it, and you’ll be able to download the new version before the end of April.
TamoSoft turned 20 this August. During the last 15 of these 20 years, we’ve been making software for Wi-Fi analysis. Part of this job is to develop drivers for Wi-Fi adapters, and in this blog post I’ll shed some light on how our development team has been testing the products of their work, and how the testing process has evolved over these 15 years, along with the evolution of wireless standards and adapters. Below you’ll find many photos (often referred to as “geek porn”) and technical details. Continue reading “All You Wanted to Know About Testing Wi-Fi Adapters, But Were Afraid to Ask”
