Battery-free technology can power electronic devices using ambient radiofrequency signals
Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module—developed by a team led by scientists from the National University of Singapore (NUS)—can now convert ambient or "waste" RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries. RF energy harvesting technologies, such as this, are essential as they reduce battery dependency, extend device lifetimes, minimize environmental impact, and enhance the feasibility of wireless sensor networks and IoT devices in remote areas where frequent battery replacement is impractical. However, RF energy harvesting technologies face challenges due to low ambient RF signal power (typically less than -20 dBm), where current rectifier technology either fails to operate or exhibits a low RF-to-DC conversion efficiency. While improving antenna efficiency and impedance matching can enhance performance, this also increases on-chip size, presenting obstacles to integration and miniaturization.

Wireless-fidelity (“Wi-Fi”) is harmful due to radio-frequency radiation exposure, pulse-modulated RF carrying data, extremely low frequency (“ELF”) effect on the brain and the Wi-Fi memory effect in body tissues.
One of the unwanted effects of ELFs, Keith Cutter believes, is brainwave entrainment, where an external stimulus synchronises brainwaves with its frequency.
ELF refers to electromagnetic fields with frequencies between approximately 3 to 30Hz, which is the same range as our brains. Our brains operate within a range of frequencies, with different brainwave states corresponding to specific activities:
Delta Waves (0.5-4Hz): Associated with deep sleep, relaxation, and healing.
Theta Waves (4-8Hz): Linked to meditation, daydreaming, and increased creativity.
Alpha Waves (8-12Hz): Correspond to relaxation, closed eyes and decreased cortical activity.
Beta Waves (13-30Hz): Related to attention, mental activity and cognitive processing.
Gamma Waves (30-44Hz): Involved in sensory processing, working memory and higher-order cognitive functions.
Cutter is most concerned about ELFs at 10Hz from Wi-Fi and other sources.
In the presence of a persistent 10Hz signal, due to entrainment, the brain can shift toward that frequency. As noted above, at 10Hz the brain has decreased cortical activity.
Cortical activity refers to the electrical and chemical signals generated by neurons within the cerebral cortex, the outer layer of the brain responsible for, among other things, cognition.

Best Partner for Wireless Modules: A Comprehensive Antenna Selection Guide
n the field of wireless communication, antenna selection is crucial. It not only affects the coverage range and transmission quality of signals but also directly relates to the overall performance of the system. Among various wireless modules, finding the right antenna can maximize their potential, ensuring stable and efficient data transmission.
When designing wireless transceiver devices for RF systems, antenna design and selection are essential components. A high-quality antenna system can ensure optimal communication distances. Typically, the size of antennas of the same type is proportional to the wavelength of the RF signal; as signal strength increases, the number of required antennas also grows.
Antennae can be categorized as internal or external based on their installation location. Internal antennas are installed within the device, while external antennas are mounted outside.
In situations where space is limited or there are multiple frequency bands, antenna design becomes more complex. External antennas are usually standard products, allowing users to simply select the required frequency band without needing additional tuning, making them convenient and easy to use.
What are the main types of antennas?
External Antennas: These antennas can be classified into omnidirectional antennas and directional antennas based on the radiation pattern.
Internal Antennas: These antennas refer to antennas that can be placed inside devices.
Omnidirectional Antennas: These antennas radiate signals uniformly in the horizontal plane, making them suitable for applications that require 360-degree coverage, such as home Wi-Fi routers and mobile devices.
Directional Antennas: These antennas have a high emission and reception strength in one or more specific directions, while the strength is minimal or zero in others. Directional antennas are primarily used to enhance signal strength and improve interference resistance.
PCB Antennas: These antennas are directly printed on the circuit board and are suitable for devices with limited space, commonly used in small wireless modules and IoT devices.
FPC Antennas: FPC antennas are flexible printed circuit antennas that are lightweight, efficient, and easy to integrate.
Concealed Antennas: Designed for aesthetic purposes, concealed antennas can be hidden within devices or disguised as other objects, making them suitable for applications where appearance is important without compromising signal quality.
Antenna Selection Guide
When selecting the appropriate antenna for a communication module, it's essential to first determine whether to use an internal or external antenna based on the module's structure.
External Antennas: These antennas offer high gain, are less affected by the environment, and can save development time, but they may take up space and impact the product's aesthetics.
Internal Antennas: These have relatively high gain and are installed within the device, maintaining a clean and appealing exterior.
Sucker Antennas: These provide high gain and are easy to install and secure.
Copper Rod Sucker Antennas: Made from large-diameter pure copper radiators, these are highly efficient with a wide bandwidth.
Rubber Rod Antennas: Offer moderate gain at a low cost.
Fiberglass Antennas: Suitable for harsh environments and ideal for long-distance signal
External Directional Antennas
Typically used in environments with long communication distances, small signal coverage areas, and high target density.
Panel Antennas have high efficiency, are compact, and easy to install, while considering the impact of gain and radiation area Yagi Antennas offer very high gain, are slightly larger, and have strong directionality, making them suitable for long-distance signal transmission; however, attention must be paid to the antenna's orientation during use
Internal Antenna Selection
Most internal antennas are affected by environmental factors and may require custom design or impedance matching
Spring Antennas are cost-effective but have low gain and narrow bandwidth, often requiring tuning for good matching when installed Ceramic Patch Antennas occupy minimal space and perform well, but have a narrow bandwidth

The FCC establishes guidelines for electromagnetic compatibility, radio frequency emissions, and more, to prevent interference and protect consumers.
Wireless Standards
Compliance with established wireless standards is fundamental to ensuring device interoperability and safety. Two widely recognized standards organizations are the Institute of Electrical and Electronics Engineers (IEEE) and the Wi-Fi Alliance. Devices must meet these standards to ensure that they can effectively connect to wireless networks and function correctly.
Radio Frequency (RF) Emissions
One of the primary concerns in wireless device compliance is the emission of radio frequency signals. Wireless devices must not emit harmful interference that can disrupt other wireless networks or devices. Manufacturers are required to conduct extensive testing to ensure their products conform to permissible RF emissions limits.
Electromagnetic Compatibility (EMC)
EMC compliance is crucial to prevent electromagnetic interference between wireless devices and other electronic equipment. Compliance ensures that wireless devices can coexist harmoniously with other electronic devices, enhancing user experience and preventing conflicts.
SAR (Specific Absorption Rate)
SAR measures the amount of radio frequency energy absorbed by the human body when using a wireless device. To protect users from excessive exposure to radio waves, regulatory bodies establish maximum SAR limits. Manufacturers must test and disclose the SAR levels of their products, enabling consumers to make informed choices.
Product Labeling and Certification
Regulatory compliance often requires manufacturers to obtain certification for their wireless devices. These certifications, such as FCC, CE (for European markets), or other regional certifications, demonstrate that a product meets all relevant safety and performance standards. Labeling on the device indicates its compliance status, ANATEL Certification for Brazil allowing consumers to identify certified products easily.

SDR Research
Tools
GQRX - Spectrum Analyzer
RFanalyzer - Spectrum Analyzer for Android
Universal Radio Hacker - Investigate Wireless Protocols like a boss
ooktools - On-off keying is used extensively in IoT projects
fldigi - I'm not a big fan of fldigi, but its there for when you need to demodulate a common signal
Tools for more specialty purposes
Salamandra is a tool to find spy microphones
rpitx is a RF transmitter for Raspberry PI
Tactics
You don't need to learn DSP, or get your Ham license to explore radio signals. I didn't. You could even explore interesting signals such as vehicle key fobs without learning either, but learning these things will increase your understanding of signals and aid in your ability to go beyond the limitations of your tools.
Digital Signal Processing
The Scientist and Engineer's Guide to DSP was my introduction to DSP and I highly recommend it. Its free online and can be purchased in physical form.
Think DSP in Python is on my todo list. Also free online can can be purchased in physical form.
HAM Radio
Though I haven't taken the test yet. Covid was a major interruption in my plans, and I also plan to pass all 3 tests in one day. Using my personal test taking process, I would first start by reading No-Nonsense Study Guides.
Then take a pretest. Its important that you read all of the material before you take a pre-test as the goal is to retain knowledge, not just memorize a test. Most of the study should be reading/practicing the material, with few pre-tests as self assessments.
There are plenty of apps on Android (and I imagine IOS) that you can use. You need to get 74% to pass the exam, but I always shoot for 90%. If you get 90% on the pre-test, then move on to taking the actual exam.
If you didn't get 90% on the pre-test. The pre-test should be able to break down your score across various sections. Note the sections you're weakest in. From here, I would recommend switching over to the ARRL study guide as they are more detailed and only study the sections you're weakest end. When you complete all those sections, then take another pre-test and repeat until you're ready to take the exam.
Techniques
Accuracy
Radio is a science, but the tools that we can afford as hobbyists are not accurate. The three issues I face is drift, noise, and clock.
Drift occurs typically from your SDR getting hot and is a problem that grows across the session. To counter drift, you'll need to recalibrate your SDR to a Nation Weather Radio station. Find the frequency used in your area and tune to that frequency. You'll notice that you're probably a little off, this is the fault of your SDR not the National Weather Radio station. Set the offset of your SDR until your frequency of the station matches the one advertised. You'll then want to bookmark this frequency and check back to it every hour to insure that your SDR hasn't drifted.
Noise can interfere with interpreting weak signals (either distant, low powered, or both). To reduce noise and improve your signal collection, I'd suggest these guides for reducing on-site noise sources and external noise sources.
Signal Identification
Most signals are standardized or frequently used that dont require extensive analysis, but just identification.
The Signal Identification Wiki is a great place to start, and if that doesn't work, check out the sub-reddit r/signalidentification
This is an archived site that has a collection of digital signals that you could test your demodulation tools with.
Signal Analysis
Signal analysis is for those proprietary signals. As always, remember your ABC's.
Radio signals are fleeting. If you don't capture them, they may not repeat themselves. Don't worry about demodulating them at first. Capture the signals, and you can demodulate them at any time later.
Even if you're not able to record IQ data, for example you're listening to someone else's remote radio (there are a lot around the world on the internet), recording the audio which can be analyzed by tools such as fldigi.
I should add a lot more stuff here in the future.
The Signal Identification Wiki is a great place to start, and if that doesn't work, check out the sub-reddit r/signalidentification

The Hazards of Drone Technology and Its Impact on Others
As the drone sector has experienced significant growth, certain individuals and groups worldwide have begun to utilize drones for harmful intentions. Many of us have encountered news stories detailing the misuse of drones and have questioned whether effective anti-drone technologies exist to counteract these actions. The reality is that such technologies have been available for years in military applications, yet the pressing issue remains how to implement them legally in non-combat environments without causing collateral damage.
A variety of companies focused on anti-drone technologies have reacted to reports concerning troublesome drones by marketing their offerings. They have developed an array of products, such as anti-drone rifles, shotgun ammunition designed for drone interception, trained raptors, net guns, laser systems, missile launchers, radio signal disruptors, and GPS spoofing tools. Some of these technologies can pose considerable disruptions to individuals, especially those piloting manned aircraft or vehicles that depend on GPS navigation, as well as users of wireless technologies like Wi-Fi.
How Some Anti-drone Technologies Can Endanger Others
There have been occasions where airport management did not align their evaluations and demonstrations with the Federal Aviation Administration beforehand. It is essential for federally funded airports to comprehend that the FAA has not sanctioned any airport to perform drone detection or countermeasure assessments unless they are part of the FAA’s drone detection program through the CRDA. Airports that permit these assessments risk violating their grant assurances. Additionally, the letter emphasizes that unauthorized drone detection and countermeasure implementations could result in numerous issues, such as electromagnetic and radio frequency (RF) interference, which can adversely affect flight safety and air traffic management.
Additionally, the American Radio Relay Alliance has communicated a warning to the FCC about the presence of video transmitters on the market that operate between 1010 and 1280 MHz, capable of transmitting at levels up to six times the legal limit. "The most pressing issue is the potential for these devices to interfere with the auxiliary targeting/transponder system utilized in air traffic control." It is important to note that one of the frequencies mentioned is legally available for amateur radio operations, while the others are not. This creates a scenario where individuals might acquire this equipment and use it on frequencies that are prohibited. What equipment is known to function within this frequency spectrum?
Counter-drone systems and the Fourth Amendment
The populace is entitled to security in their persons, homes, papers, and possessions against unreasonable searches and seizures. A warrant may only be granted based on probable cause, which must be established by an oath or declaration, and must clearly specify the area to be searched as well as the individuals or items to be confiscated.
Do drone jammers work?
It is correct that the use of jamming devices against drones is prohibited for all individuals, except for designated federal agencies. Drones share radio frequencies with numerous other technologies, such as Bluetooth and Wi-Fi. Therefore, the act of jamming drones could also interfere with the radio communications of others in the vicinity, rendering it highly illegal.
