Interference limits the capacity of cellular radio systems by creating bottlenecks that reduce performance. The two primary types of interference are co-channel interference, which occurs between cells using the same frequencies, and adjacent channel interference, which occurs between nearby frequency channels. Managing interference is important for cellular system design in order to minimize cross-talk and missed/blocked calls.
How can variables be measured in environments that are too hot, too cold, or moving too fast for traditional circuit-based sensors? A new technology for obtaining multiple, real-time measurements under extreme environmental conditions is being developed under Phase 1 and 2 funding contracts from NASA's Kennedy Space Center’s Small Business Technology Transfer (STTR) program. Opportunities for early deployment licensing and Phase 3 STTR contracts are now being accepted.
Passive, remote measuring systems can be created using new Orthogonal Frequency Code (OFC) multiplexing techniques and specially developed, next-generation SAW sensors. As a result, very cost-effective applications such as spaceflight sensing (for instance, temperature, pressure, or acceleration monitoring), remote cryogenic fluid level sensing, or an almost limitless number of other rigorous monitoring applications are possible.

Here are a few additional things you can try to troubleshoot the interference to your VCR:
- Check for any unshielded cables running near your antenna or feedline that could be picking up RF. Cables for TVs, VCRs, cable/satellite boxes, etc. should be kept at least a few feet away from antenna wires.
- Make sure your station grounding system is solid. A good earth ground on your radio equipment is important for dissipating RF. Inspect all ground connections.
- Try moving your VCR to different outlets around the house to see if the interference changes or goes away in certain locations. This can help identify if the issue is coming through the power lines.
Wireless communication technology allows transmission of information over distances without wires. It involves various technologies such as infrared, satellite communication, radio broadcasting, and microwave transmission. Common wireless standards include Wi-Fi, which allows devices to connect to the internet, and Bluetooth, which enables short-range data sharing between devices like wireless headphones. While wireless connectivity offers flexibility and easy setup, it also poses security and health risks if not implemented correctly.

This document describes the design and construction of a mobile phone jammer that uses extrinsic noise. It operates by transmitting noise signals at the same frequencies used for mobile communication, blocking signals between phones and towers. The jammer extracts noise from the environment using a microphone and mixes it with a tuning signal to cover GSM 900MHz and DCS 1800MHz bands. Testing showed the jammer decreased phone signal bars and caused phones to display "no network" within a 10m radius, demonstrating its ability to disrupt mobile networks through noise interference. The document discusses applications of jammers for improving security, education, and discipline by blocking phone signals in places like classrooms, meetings and military zones.
Electromagnetic compatibility and its effectsSubhashMSubhash
EMC refers to the ability of electrical and electronic equipment to operate properly in an electromagnetic environment without causing or suffering from electromagnetic interference. EMI can be caused by various onboard sources and affect avionic systems through errors, noise, or false readings. To reduce EMI, the noise source, coupling path, and susceptible receiver must be addressed through techniques like shielding, filtering, wiring separation, and proper grounding and bonding of the aircraft.

Radio waves are a form of electromagnetic radiation that are invisible to the human eye. They have a wide range in the electromagnetic spectrum between gamma rays and microwaves. Radio waves are used for many modern technologies like wireless networks, television, mobile phones, radars, and satellite communication. They transmit information by varying the amplitude or frequency of the radio signal, which is received by an antenna and converted into sound or other signals. Radio waves are essential for much of modern technology and communication.
Presentation on emc testing and measurementRajat Soni
discuss the options for EMC testing for compliance with the EMC Directive from the point of view of a manufacturer who wishes to achieve as much progress as possible, in-house, on a limited budget. It is not addressed to test houses nor to those manufacturers who have the resources to emulate most or all of the facilities of an accredited test house in their own premises. There are many small-to-medium sized enterprises who are able to dedicate a modest budget of several thousands or tens of thousands of pounds to an in-house EMC test set-up and who wish to gain the maximum benefit from so doing.
Three phase emi filters help to extract unwanted current conducted through wiring or cables, while allowing desirable currents to flow freely. This slide can help you to understand more about three phase power line filters.

Periodic impulsive noise reduction in ofdm based power line communicationeSAT Publishing House
This document presents a method for reducing periodic impulsive noise in OFDM-based power line communication systems. It uses an adaptive notch filter and adaptive LMS filter to detect and remove periodic impulsive noise from OFDM signals transmitted over power lines. Simulation results show that both filtering methods improve the bit error rate of the power line communication system compared to no filtering. The adaptive LMS filter provides better noise reduction and lower bit error rates than the adaptive notch filter alone. The proposed noise filtering approach improves the performance of OFDM power line communication systems operating in noisy power line environments.
Wireless charging of mobile phones using microwavesNaveen Kumar
The document proposes a method for wirelessly charging mobile phones using microwaves. It discusses the electromagnetic spectrum and why the microwave region was selected. The system would include a microwave transmitter that sends power to a rectenna array attached to the phone via a slotted waveguide antenna. This would allow phones to charge without wired connections. However, concerns include potential health effects of the radiation and high costs to implement such a system.
This document describes the design and operation of a simple wireless FM microphone transmitter. The transmitter uses an electret microphone, two transistors, and a tuned coil to modulate an FM carrier signal between 87-108 MHz. The audio signal from the microphone is amplified and used to vary the resonant frequency of the tuned coil, transmitting the audio over FM radio frequencies. The transmitted signal can be received on any standard FM radio within a range of over 300 meters. The wireless microphone allows for freedom of movement and avoids issues with cables. Potential applications include entertainment, broadcasting, and public speaking.

1. The document discusses electromagnetic field (EMF) radiation from mobile communication antennas and compliance approaches.
2. It covers topics like EMF radiation, non-ionizing radiation, mobile network architecture, radiation effects on human health, and regulatory safety limits.
3. Measurement techniques for assessing EMF exposure are presented, including calculating total equivalent isotropically radiated power (EIRP) and classifying sites based on accessibility and compliance with exposure limits.
Mobile computing allows end users to access resources and information while mobile through technologies like internet access, mobile applications, and wireless communications. The history of wireless communication spans from the 1890s with the first wireless communication to current 5G networks. Wireless transmission involves communicating without a physical link by transmitting signals through air which are received by antennas.
This document discusses techniques for enhancing the signal-to-noise ratio in analytical measurements. It describes what the signal-to-noise ratio is and explains common sources of noise like thermal noise, shot noise, and flicker noise. It then discusses various hardware and software methods for improving the SNR, such as shielding, grounding, difference amplifiers, filtering (low-pass, high-pass, band-pass), ensemble averaging, and moving averages. Modulation and lock-in amplifiers are also covered as techniques to extract low-level signals from noise.
[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
High performance Serverless Java on AWS- GoTo Amsterdam 2024Vadym Kazulkin
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Freshworks Rethinks NoSQL for Rapid Scaling & Cost-EfficiencyScyllaDB
Freshworks creates AI-boosted business software that helps employees work more efficiently and effectively. Managing data across multiple RDBMS and NoSQL databases was already a challenge at their current scale. To prepare for 10X growth, they knew it was time to rethink their database strategy. Learn how they architected a solution that would simplify scaling while keeping costs under control.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
