Passive RFID tags have been widely adopted, and some applications show creative adaptation to unmet needs. It’s interesting to see how advances in technology often are adapted to applications that were not highlighted in their original “use case” scenarios and how clever people adapt or leverage new technologies in unscripted ways. A good example of […]

10BASE-T1S brings a single pair of wires to the network edge
The 802.3cg Ethernet standard uses a single pair of wires, and it manages data flow without switches, making it suitable for industrial networks at a lower cost than traditional Ethernet. Industrial plants have long used digital data to monitor and control their production facilities. Networks in factories, data centers, and commercial buildings push the edges…
Securing devices for the IoT — managing memory
Memory management is important in all digital electronic devices including devices designed for use on the Internet of Things (IoT). It supports efficient resource allocation and memory utilization and prevents memory fragmentation, improving efficiency. It also supports memory protection and device security. This FAQ briefly reviews the common weakness enumeration (CWE) scheme for identifying software […]
Securing devices for the IoT – firmware, software, and OTA
Over-the-air (OTA) updating of firmware and software on Internet of Things (IoT) devices is a requirement, not an option. The large number of IoT devices makes manual updates impractical and even dangerous. This FAQ reviews two key tools for managing and implementing OTA for IoT devices: open-source standards for managing resource-constrained devices and industry standards […]
How is sensing used to detect glaucoma?
The term glaucoma is used to describe a group of eye diseases. In addition to damaging the eye’s optic nerve, glaucoma can result in vision loss and even blindness. About 3 million Americans have glaucoma, but the disease affects more than 67 million people worldwide and is the second leading cause of blindness. Glaucoma occurs […]
Securing devices for the IoT — minimize the attack surface
An attack surface is the sum of all the attack vectors or ways that an attacker can gain malicious access to a network or system. The growth in remote work and the adoption of cloud services have increased the number of attack vectors and the size of the attack surface for most organizations and applications. […]
How does a quantum radar sensor work?
It generates quantum entanglement between a microwave resonator and a signal that is emitted toward a target and can theoretically make radar detection up to four times faster in scenarios with comparable signal power and target noise. It also reduces susceptibility to jamming. A microwave quantum radar begins with a stream of entangled visible-frequency photons […]
Securing devices for the IoT – FIPS 140-3 and common criteria
For developers of IoT devices and networks, the Federal Information Processing Standard (FIPS) 140-3 and the Common Criteria (CC) serve different but complementary functions. FIPS 140-3 is designed for validating software and hardware in cryptographic modules, while CC is designed to evaluate security functions in IT software and hardware. In both cases, there are related […]
How can quantum sensors and quantum batteries improve electric vehicle operation?
In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using…
How do you test an Open RAN installation?
Open RAN telecom networks need testing for each disaggregated component, but that’s not enough. End-to-end testing is also necessary. In How do Open RAN interfaces work?, we covered how Open RAN redefines traditional RAN architecture by disaggregating it into three primary components: the radio unit (RU), distributed unit (DU), and centralized unit (CU). This paradigm…
