The Invisible Rainbow, a Book Review

Over the last 220 years, society has evolved a universal belief that electricity is ‘safe’ for humanity and the planet. Scientist and journalist Arthur Firstenberg disrupts this conviction by telling the story of electricity in a way it has never been told before—from an environmental point of view—by detailing the effects that this fundamental societal building block has had on our health and our planet.

The humble beginnings of 5G
Many folks don’t know that the first 5G deployments in the United States weren’t for mobile devices at all. In 2017, the carriers began trialing fixed wireless 5G services as a replacement for wired broadband home internet. Closed trials of 5G home internet ran well into 2018 before becoming commercially available later that same year.

It wasn’t until early 2019 that the first 5G mobile networks rolled out. Verizon led the way in April with a relatively small 5G footprint in core areas of Chicago and Minneapolis, arguably beating out three South Korean carriers to become the first commercial 5G smartphone service on the planet.
