The battery-powered Starlink Mini is here
Starlink is a life-changing Internet service that connects people and villages too remote for towers and cables to reach. My own Starlink Mini has been critical in helping me pursue life as a digital nomad from almost anywhere in Europe. And right now, Starlink’s the only game in town for relatively cheap and fast consumer internet that can be quickly deployed into data dead spots.
My overriding thought after using the PeakDo LinkPower for the last few weeks is this: why doesn’t SpaceX make one of these?
Yes, you can store data on a bird — enthusiast converts PNG to bird-shaped waveform, teaches young starling to recall file at up to 2MB/s
Who needs Starlink when you’ve got an actual starling

Amazon is hoping to get a good rhythm going with the launch and deployment of Project Kuiper, its 3,232-satellite internet constellation, which began operational flights in April. The tech giant said on Thursday that its nearly $140 million investment in Florida is a cornerstone to making that happen.
While shown in the background of photos and hinted at in other public relations materials during its first three launch campaigns, Amazon confirmed on July 24 that its payload processing facility (PPF) at the Kennedy Space Center (KSC) entered service back in April in time to support its first operational launch on a United Launch Alliance (ULA) Atlas 5 rocket.
“There is no better place than Florida’s Space Coast to fulfill Kuiper’s promise to bring broadband to unserved and underserved across the nation and world,” said Brian Huseman, Amazon’s vice president for public policy and community engagement, in a statement. “We are proud to make investments in Florida that will impact the local community and ultimately our customers. We look forward to our long-term partnership with Space Florida, NASA, Space Force, and state and local officials, as well as our launch providers and community partners.”
New surveillance technology can track people by how they disrupt Wi-Fi signals
Hi-tech surveillance technologies are a double-edged sword. On the one hand, you want sophisticated devices to detect suspicious behavior and alert authorities. But on the other, there is the need to protect individual privacy. Balancing public safety and personal freedoms is an ongoing challenge for innovators and policymakers.
This debate is set to reignite with news that researchers at La Sapienza University in Rome have developed a system that can identify individuals just by the way they disrupt Wi-Fi signals.
The scientists have dubbed this new technology “WhoFi.” Unlike traditional biometric systems such as fingerprint scanners and facial recognition, it doesn’t require direct physical contact or visual feeds. WhoFi can also track individuals in a larger area than a fixed-position camera, provided there is a Wi-Fi network.
New memristor-based system could boost processing of radiofrequency signals
The development of more advanced technologies to process radiofrequency signals could further advance wireless communication, allowing devices connected to the internet to share information with each other faster and while consuming less energy. Currently, radio frequency signals are processed using software-defined radios (SDRs), systems that can modulate, filter and analyze signals using software rather than hardware components.
Despite their widespread use, these systems rely on purely digital hardware in which computing and memory modules are physically separated, leading to constant data shuttling between the two and hence extra energy consumption. Furthermore, the extensive use of circuit components known as analog-to-digital converters (ADCs), which convert incoming radiofrequency signals into digital values that can then be processed by digital computers, often results in processing delays (i.e., latency) and substantial energy consumption. Electronics engineers have thus been trying to develop alternative systems that can directly manipulate signals in their original (i.e., analog) form, which would reduce the movement of data and lower energy consumption.
Researchers at the University of Massachusetts Amherst, Texas A&M University and TetraMem Inc. recently introduced a promising new system for processing analog radiofrequency systems, which is based on non-volatile memory devices known as memristors integrated on a chip. Their proposed system, presented in a paper in Nature Electronics, was found to process radiofrequency signals significantly faster and more energy-efficiently than existing SDRs.
Quantum internet moves closer as researchers teleport light-based information
Quantum teleportation is a fascinating process that involves transferring a particle’s quantum state to another distant location, without moving or detecting the particle itself. This process could be central to the realization of a so-called “quantum internet,” a version of the internet that enables the safe and instant transmission of quantum information between devices within the same network.
Quantum teleportation is far from a recent idea, as it was experimentally realized several times in the past. Nonetheless, most previous demonstrations utilized frequency conversion rather than natively operating in the telecom band.
Researchers at Nanjing University recently demonstrated the teleportation of a telecom-wavelength photonic qubit (i.e., a quantum bit encoded in light at the same wavelengths supporting current communications) to a telecom quantum memory. Their paper, published in Physical Review Letters, could open new possibilities for the realization of scalable quantum networks and thus potentially a quantum internet.
