An air-filled core lets light travel at a speed close to 300 thousand kilometres per second, and delay fell by about 30%. The test ran on a specially assembled line, not a live network.
SpaceX published photos of ground tests in which the Super Heavy B22 booster was lifted to catch height. Flight 15 is planned for 14 November, but the FAA licence has not yet been issued.
Under the IMT-2020 (5G) Promotion Group, test terminals on the Qualcomm X105 modem were checked with ZTE network equipment in uplink and beam-management scenarios.
A single silicon photonic platform with a hybrid laser covered both short data-center-scale links and long-haul lines in an experimental demonstration.
In a home experiment, a simple receiver picked up a person's movement as fading stripes on a TV signal spectrogram. According to the author, WiFi and LTE work the same way.
A cross-sectional study found that frequent messaging with close friends and wider groups tracked higher well-being, while contact with online-only friends tracked lower.
Samtec expanded its AcceleRate mP family with 10 mm stack-height UDM6 and UDF6 connectors that combine 64 Gbps PAM4 signals and 15 A power blades, saving board space.
SoftBank and US company Sceye will manufacture, launch and operate high-altitude platforms for nationwide mobile service in Japan. Fleet size and timetable are not disclosed.
A Chinese team including China Telecom engineers demonstrated bidirectional transmission over hollow-core fibre, with a signal delay of 3.43 ms over the whole link.
The three-day MWC26 Doha opened on 8 November in Qatar. GSMA named global standards and connecting offline populations in MENA as its priorities.
Researchers checked 3,839 links to online medicine retailers in Google results for six active ingredients; 36.3% led to sellers without recognized authorization.
The 8U nanosatellite from the University of Athens linked with the Holomondas optical station using Astrolight terminals, a demonstration of laser data links for small satellites.
KAIST and Caltech researchers determined the refractive index and absorption of barium titanate, a material for optical modulators, from ultraviolet to far-infrared.
The update raises the maximum Bluetooth data rate from the current 2.5 Mbit/s to 7.5 Mbit/s. First devices with Bluetooth 7.0 are expected in early 2027.
A slow-light silicon photonic crystal modulator with an integrated electro-optic equalizer achieved 200 Gb/s data rates in prototype tests.
Researchers presented a coherent silicon photonic architecture operating without optical amplification over short links and reaching over 4,400 km.
Researchers have developed and psychometrically validated a seven-item scale to measure consumer willingness to disconnect from digital devices.
A Hefei team obtained spin–photon entanglement from a single rubidium atom directly in the C-band, the minimum-loss band of optical fiber, and observed a Bell inequality violation.
Under a multi-year deal, SpaceX will use Qualcomm's Dragonwing cellular infrastructure in its Starlink Mobile network, with first deployments set for 2027.
Researchers at North Carolina State University made a plasma filament in air with a laser and used it to transmit a 30 MHz signal. It is a laboratory demonstration at a distance of about 5 cm.
