Connectivity
Wi-Fi, Bluetooth, mobile networks and the smart home: why the signal behaves the way it does.
Why did the FCC replace a vacant FM channel in Whitehall with a new one?
The Federal Communications Commission has swapped the FM allotment for Whitehall, Michigan. Channel 258A now takes the place of Channel 248A, which fell vacant after the previous station gave up its license.
Why did the Wi-Fi Alliance publish 15 AI papers and podcasts on a single page?
The Wi-Fi Alliance posted a curated library of 15 technical resources that link Wi-Fi 7, Wi-Fi 8, and 6 GHz spectrum to artificial intelligence workloads. Engineers can filter the list by technology — from Wi-Fi CERTIFIED 7 to Protected Management Frames — to find the spec or case study that matches their deployment.
How does Bluetooth turn low-power connectivity into measurable sustainability results?
Bluetooth technology connects sensors and devices using very little power. The Bluetooth SIG published a blog post showing how this connectivity produces measured sustainability improvements in three different sectors.
How Well Do FDA-Cleared AI Tools Actually Detect Pulmonary Embolism in Real Hospitals?
A new study tests two FDA-cleared AI tools that flag blood clots in the lungs. The tools run on a commercial platform used in 17 hospitals across a large academic health system.
What Changes When Quantized Models Get a Complexity Score Based on Behavior?
A research paper posted on arXiv introduces Behavioral Capacity Certificates, a way to measure the complexity of quantized language models by what they actually compute rather than by the codes stored in their weights. The method treats two deployments as equivalent when they produce the same bounded loss, even if their weight codes differ.
How Does Mira Make MoE Models Run Faster on a Single GPU?
A new system called Mira helps large language models run on a single graphics card. It predicts which parts of the model will be needed next and moves them into fast memory before they are requested.
What will the FCC decide at its September 30 open meeting?
The Federal Communications Commission has scheduled an open meeting for September 30, 2026. The session will cover five rulemaking items that could reshape satellite spectrum, ultra-wideband devices, emergency calling, and robocall protections.
What does Bluetooth networked lighting control actually change in a building?
Bluetooth networked lighting control is a wireless system that lets lights talk to sensors and each other. The Bluetooth SIG published a breakdown showing it cuts waste far beyond electricity bills.
How Did OpenAI Design Its First Chip in Under Two Years?
OpenAI built its first AI accelerator chip. The chip is called Jalapeño and it entered production after a timeline that chip veterans call unprecedented.
Why Are 38,507 Jerify Magnetic Figures Being Recalled?
The CPSC has recalled Jerify Magnetic Humanoid Toy Sets because the magnets can detach and be swallowed by children. Two children have already been hospitalized after ingesting magnets from the limbs. About 38,507 sets were sold on Amazon between October 2022 and May 2026.
Why won't a phone bought in the US see a Ukrainian network?
A band in a mobile standard is not one stretch of spectrum but two: one where the phone transmits, another where it receives. In Ukrainian LTE 800 those halves sit in the reverse order, and the filter in an American handset, tuned to its own order, misses the second half.
What happens when an inference chipmaker plugs into NVIDIA's rack-scale fabric?
d-Matrix announced it will connect its next-generation Raptor XPUs to NVIDIA's AI infrastructure platform using NVLink Fusion. The move lets the company skip building its own rack architecture and instead use NVIDIA's validated MGX designs.
Why did the Bluetooth standards body just open a formal entity in Tokyo?
The Bluetooth Special Interest Group announced the creation of Bluetooth SIG Japan G.K. on 4 September 2026. The new entity sits in Tokyo and gives the organisation a legal presence inside the country for the first time.
What changed in Azure AI Foundry Model Router and why does it matter for production workloads?
Microsoft updated the Model Router in Azure AI Foundry. The service picks a model for each request instead of forcing teams to choose one upfront.
How do you track a bumblebee that weighs less than a grain of rice?
A research team built a radio tracker that fits on a bumblebee and consumes less than 180 microwatts. The system follows the insect across hundreds of metres with roughly fifteen-metre accuracy.
Why doesn't 5 GHz Wi-Fi reach the far room?
A router hands out two networks: one is faster, the other reaches further. The speed comes from how much free spectrum the 5 GHz band happened to get. The wall penalty comes from one exponent in an ITU table — and for brick that exponent is almost zero, which is why the usual rule of thumb fails in a brick house.
What does Attachment 14 change for developers with apps in the EU?
Apple has added Attachment 14 to the Developer Program License Agreement. The attachment sets new terms for apps distributed in the European Union covering alternative distribution, alternative payments, and business terms. Developers must accept the updated agreement by October 1, 2026 to keep distributing apps in the EU.
What does 100 percent BT.2020 actually look like on a living-room screen?
Samsung announced its 2026 TV and audio lineup in August. Reviewers from major publications have now tested the new models.
