Only 11% of organizations have a ‘fully automated’ test strategy: Keysight study

Despite widespread interest in increasing testing automation, it remains a challenge for organizations, according to new research commissioned by Keysight Technologies. Three-quarters of those surveyed said that their business relies on a combination of automated and manual testing, with only 11% reporting that they have...

Starlink downstream speeds jump in the US, but uplink slows

New analysis from Ookla shows mixed results for SpaceX's low-Earth orbit (LEO) satellite-based Starlink services: A big jump in downlink speeds in the U.S. and Canada, tempered by a slowdown in the uplink. Ookla reports that Starlink has boosted its median speed in the...

Test and Measurement: Softbank tests autonomous blimp

Softbank, continuing its interest in high-altitude communications, says it has successfully tested a tethered autonomous aerostat during a field trial in Japan. Working with U.S.-based Altaeros Energies (in which Softbank is an investor), the two companies say they "achieved stable and wide-area network coverage" with...
