JANUARY 2025 I SMT007 MAGAZINE 53 Other Observations and Tips • Use social media: Many trade shows have hashtags. Use them to share your experi- ences, connect with attendees, and stay updated on what's happening. • Be open to surprises: Some of the best discoveries at trade shows are the ones you didn't plan for. Leave a little flexibility in your schedule for serendipity. • Take care of yourself: Trade shows are exhausting. Stay hydrated, eat well, and get enough rest to keep your energy levels up. Trade shows are what you make of them. ey're not just about booths and bro- chures—they're about connections, learning, and opportunities. Whether you're walking the floor, attending a technical conference, or networking over coffee, ever y interaction is a chance to grow your business and expand your horizons. So, the next time you attend a trade show, don't just show up. Show up with purpose. Engage, learn, and leave with something that moves the needle for your company. at'll get you the biggest bang for your trade show buck. SMT007 Dan Beaulieu is an I-Connect007 columnist.

But for the signals to reach all the way and not be disturbed along the way, hypersensitive receivers and noise- free amplifiers are required. Now, researchers at Chalmers University of Technology in Sweden have created a system that, with a silent amplifier and record-sensitive receiver, paves the way for faster and improved space communication. The researchers' communication system uses an optical amplifier in the receiver that amplifies the signal with the least possible noise so that its information can be recycled. Just like the glow of a flashlight, the light from the transmitter widens and weakens with distance. Without amplification, the signal is so weak after the space flight that it is drowned out by the electronic noise of the receiver. After twenty years of struggling with disturbing noise that impaired the signals, the research team at Chalmers was able to demonstrate a noise-free optical amplifier a few years ago. Due to the limited resources and minimal space on board a space probe, it is important that the transmitter is as simple as possible. By allowing the receiver on Earth to generate two of the three light frequencies needed for noise-free amplification, and at the same time allowing the transmitter to generate only one frequency, the Chalmers research- ers were able to implement the noise-free amplifier in an optical communication sys- tem for the first time. The results show an outstanding sensitivity, while complexity at the transmitter is modest. (Source: Chalmers University of Technology) Faster Space Communication With Record-sensitive Receiver
