Preserving the Internet by Vinton G. Cerf

The Internet has become a global, complex, layered, and increasingly indispensable ecosystem. For purposes of this column, “Internet” includes the underlying digital transport infrastructure including subsea and land-based fiber and cable, orbiting satellites, the networks of routers, the Domain Name System, datacenters and their networks, edge devices of all kinds (laptops, desktops, pads, smartphones, Internet-enabled devices, and sensors), the World Wide Web, content distribution systems and, for all I know, the kitchen sink.

Australia installs first space laser optical ground station in southern hemisphere

Recently, my colleagues and I swung a half-tonne telescope onto the roof of the physics building at the University of Western Australia.

For a tense moment, my career hung from a crane hook.

The telescope is the first of its kind in the southern hemisphere and represents a new generation of space communications using lasers.

Undersea cables bring Pacific nations online, but there are concerns China is trying to tap in

Across the Pacific, undersea cables weave between island nations, bringing them online and, in some cases, connecting them to Australia, but some governments fear this interconnectivity comes with risk.

New ITU standards to boost Fibre to the Home from 10G to 50G

Millions of homes and businesses access global networks through the cost-efficient Passive Optical Network (PON) technologies standardized by ITU. The next generation, known as “Higher Speed PON”, will provide for speeds of 50 Gbit/s per wavelength, up from the 10 Gbit/s of its predecessors.

The challenges satellite Internet must address for take off

The satellite Internet industry has taken off at great speed in the last year, as companies like SpaceX, OneWeb and Amazon each work to build satellite-based networks consisting of thousands of small individual satellites. SpaceX has launched more than 1,000 of its Starlink high-speed Internet satellites to date and now has permission from the FCC to launch 12,000 satellites in the first phase of its deployment. While SpaceX has led the way, we are seeing OneWeb and Amazon follow at breakneck speed, as each of them strives to connect the unconnected parts of the world.

Improved Internet connectivity and skills have helped many countries to cope with the health and economic crisis from COVID-19. Yet the pandemic has raised the bar for the digital transition and underscores the need to close the digital divides that risk leaving some people and firms worse off than others in a post-COVID world, according to a new OECD report.
