Bell Labs sets world record broadband speed, hits 10 Gbps using telephone wires

Add as a preferred source on Google

These days, telephone lines are associated with antiquated tech. Who has a hard line phone, outside of mom, your aunt, or grandma, right?

Phooey to that, says Bell Labs, which broke a world broadband speed record by achieving 10 Gbps using traditional telephone wires, which contain copper.

Bell Labs is the research division of Alcatel-Lucent, a networking firm. Bell Labs combined copper telephone wires with a new prototype technology called XG-FAST. Bell Labs aims to use XG-FAST to provide 1Gbps of “symmetrical” service, and could pave the way to provide homes and businesses with solid Internet connections in areas where it doesn’t make sense, from either infrastructure or financial standpoints, to lay down fiber-based cables all the way to their final destinations. This way, Alcatel-Lucent says, you could use fiber to bring the connection “to the curbside, wall or basement of a building,” and then employ copper-based wires to make it the rest of the way home.

“The Bell Labs speed record is an amazing achievement, but crucially in addition they have identified a new benchmark for ‘real-world’ applications for ultra-broadband fixed access,” Federico Guillén, President of Alcatel-Lucent’s Fixed Networks business says. “By making 1 gigabit symmetrical services over copper a real possibility, Bell Labs is offering the telecommunications industry a new way to ensure no customer is left behind when it comes to ultra-broadband access.”

Alcatel says that 1 Gbps symmetrical service can be delivered using 70 meters of copper wire.

According to Alcatel, XG-FAST is based on another technology called G.fast, and it says that the latter should be “commercially available” by 2015.

With that in mind, it will be interesting to see how long it will take for XG-FAST to roll out as well, and whether that can deliver what it promises.

As generative AI becomes increasingly capable of producing videos that are nearly indistinguishable from real footage, the race is no longer just about creating synthetic media. It's about detecting it before it spreads.

At SIGGRAPH 2026, NVIDIA unveiled Synthetic Video Detector, a new AI-powered verification tool designed to identify AI-generated videos with remarkable speed and accuracy. Rather than replacing traditional fact-checking or forensic analysis, the company says the technology is intended to give newsrooms, broadcasters and enterprises another layer of confidence before synthetic videos enter the public domain.

Samsung’s secret AI chip could finally cool down Exynos phones
Samsung's GAIA AI chip is landing in laptops first, but its shared DNA with Exynos hints at a real fix for phones down the line.

If you've ever owned an Exynos-powered Galaxy phone, you already know the drill: heavy tasks like capturing back-to-back pictures or photos for a while, heavy gaming, or rendering videos turn your device into a hand warmer. 

In such a situation, the battery bar drops faster than usual as well. Turns out, Samsung might be working on the fix, and it's coming in a way nobody expected.
