Reduce Uncertainty with an RF Recorder
In engineering, uncertainty has always been a terrible monster. In fact, the entire field of test and measurement exists to eliminate it wherever possible. Despite this never-ending quest, some portions of RF system design remain plagued by guesswork and rules of thumb. We’re not here to postulate but to reduce uncertainty.
Predicting real world signal propagation is a classic example. Billions of dollars are spent on computer simulation software to generate propagation models, yet it may still come down to a guess, then a test, and a bit of waiting to see what happens.
One of the ways to change this frustrating dynamic is to reduce uncertainty with an RF recorder.
Capture fleeting signals.
An RF recorder creates a permanent record that will be the envy of all your colleagues. No one wants to be the engineer who’s nervously watching transient signals appear on the screen and disappear into the ether forever. When your team is in the field, you’ll be able to rest easy knowing that you can recall and inspect those fleeting signals any time you want.
Interrogate, don’t speculate.
As a seasoned professional, you know that failures are inevitable. Often, the best way to capture those failures is with an RF recorder. While others are using handwritten notes and memories to speculate on the cause of the failure, you will have a permanent record of raw signal data to interrogate. You can be writing code to fix the problems while your adversary is still fumbling to figure out what happened in the field.
Quantify the real world.
Hope is not a strategy for propagation model validation. The real world is far too complex to model completely. Every time you bring an RF recorder into the field, you create a new opportunity to quantify real world propagation conditions. Ongoing iterative improvements to your models are necessary to advance performance and maintain a strategic edge.
Uncertainty has a tendency to appear with demoralizing regularity. It’s the shape-shifting enemy that can take the form of a transient signal, a bad guesstimate or incomplete propagation model. We can’t simply close our eyes and hope that it will disappear and unblock the path to a better product.
Armed with an RF recorder, you can reduce uncertainty. Leave the guesswork to your adversaries.
