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.
Smartphone users have become “human snails carrying our homes in our pockets”, with a tendency to ignore friends and family in favour of their device, according to a landmark study.
[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.
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.
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.
