Here’s What 6G Will Be, According to the Creator of Massive MIMO: Tom Marzetta, the director of NYU Wireless, explains how it will be the next level of human-to-human communication

Tom Marzetta is the director of NYU Wireless, New York University’s research center for cutting-edge wireless technologies. Prior to joining NYU Wireless, Marzetta was at Nokia Bell Labs, where he developed massive MIMO. Massive MIMO (short for “multiple-input multiple-output”) allows engineers to pack dozens of small antennas into a single array. The high number of antennas means more signals can be sent and received at once, dramatically boosting a single cell tower’s efficiency.

Nearly half of people with 4G network coverage remain offline, mainly due to high cost of Internet access: ITU and A4AI publish “The affordability of ICT services 2020”

[news release] A new policy brief from ITU and the Alliance for Affordable Internet (A4AI), finds that high costs for Internet access relative to income remain one of the main barriers to the use of information and communication technology (ICT) services worldwide. Taking income differences into account, a mobile broadband subscription with at least 1.5 gigabytes (GB) of data costs around four times more in developing countries than in developed ones.

A New Lens Technology Is Primed to Jump-Start Phone Cameras

The camera on the first iPhone way back in 2007 was a mere 2 megapixels. And it only had a rear camera; there wasn’t even a front-facing selfie shooter. Today, you’ll find multiple cameras on the front and back of phones—some of them with sensors as large as 108 megapixels, like the biggest camera on Samsung’s Galaxy S21 Ultra.

Why conspiracy theorists think 5G is bad for your health and why experts say not to worry

For all its promise, the rollout of 5G has also been fraught with rumors and conspiracy theories — most recently, a narrative spread on social media that the wireless network technology fueled the coronavirus pandemic.

It did not.
