Capturing and Decoding of PMR Signals – A Brief Introduction

Professional/Private mobile radios (PMR) are two-way radio voice communication systems, including most recognizable handheld radios and widely deployed push-to-talk systems. As these systems can employ direct communication between users, rather than sending information via a central hub (as cellphone or internet messages do), they are still the system of choice for many of those engaged in illicit activities, including criminal gangs and terrorists. As [...]

How to deal with GPS jamming and spoofing

Expanded and updated, July 2020 From ship navigation to financial transactions, we’re increasingly reliant on GPS (or other GNSS systems, such as Galileo, GLONASS or BDS BeiDou). Jamming and spoofing can therefore cause significant disruption and represent a public safety threat. Fortunately, spectrum monitoring allows detection and location of jammers and the possibility to pre-empt attacks with anti-jamming and anti-spoofing technologies. GPS Jamming [...]

RFeye Site Feature Spotlight: More Than A Bearing

Traditional direction-finding systems provide a single line of bearing to a target, as shown below in Figure 1. RFeye Site, on the other hand, can provide far more detail, and does so with a user-friendly interface, allowing operators to extract the maximum amount of geolocation information from incoming signals. Figure 1 Single Line of Bearing (LOB) Feature 1 – Color-Coded Lines of Bearing RFeye [...]

What Distance Can You Detect Drones From?

One of the most frequently-asked questions when discussing our RF drone detection system is: “At what distance are you able to detect drones? How far away can they be and still be picked up by RFeye?” And the answer, as is so often the case, is “it’s complicated” - depending on the conditions, the answer could be anything from many kilometers to tens of [...]

Interference Detection in Industry 4.0

Industry 4.0 is an overarching term used to describe the automation and computerization of industry, and in particular of manufacturing and production processes. Things that seemed like science fiction only a few years ago, like entirely automated factories and processing plants, have now become a reality. Smart warehouses include things like automated packing, automated stocktake, automated vehicles. By removing human elements from the structure entirely, [...]

Interference Hunting and Capture – From FM to 5G

With the RFeye Sens Portable I/Q recorder, it is possible to track down and record even hard-to-find interference sources. So here’s the scenario - you’ve created a brilliant new piece of wirelessly-enabled technology, and you’ve tested it extensively in a laboratory setting. Everything is working perfectly until it makes contact with the real world, at which point, unexplained interference problems begin to occur. As [...]

CRFS Spring Webinar Series

As COVID-19 continues to disrupt normal life across the globe, we’re all having to adapt to the (hopefully temporary) new reality of working remotely. As part of that process, we wanted to reach out directly to our customers and to the wider RF community by organizing a series of interactive webinars. We’ve chosen a selection of topics that we hope will prove useful and [...]

Tracking Low Earth Orbit Satellites

What are LEO satellites, what can they be used for, and how can they be tracked using RF? In this blog, we will find out. Low Earth Orbit (LEO) satellites are far from a new phenomenon (indeed, the very first satellite, Sputnik, was an example back in 1957), but they are attracting increasing interest for their current and potential future uses in financial services, [...]
