Optus looks to spend $1.5m on transportable 4G small cells – Telco/ISP

Optus is set to devote $1.5 million in a fleet of transportable modest cells that are lighter and a lot easier to deploy in catastrophe zones than the telco’s current fleet of satellite cells on trailers or SatCats.

The telco unveiled the planned financial investment in its newest sustainability report [pdf], declaring that the modest cells could enable it give “a extra helpful response to normal disasters and emergencies.” 

“Our catastrophe administration fleet utilises SatCats (a satellite mobile on a trailer that utilizes satellite transmissions for protection in a minimal selection, with out the will need for infrastructure),” it said.

Next-Gen Solar Cells Can Harvest Indoor Lighting for IoT Devices

Billions of Web-connected units now adorn our partitions and ceilings, sensing, monitoring, and transmitting details to smartphones and significantly-flung servers. As devices proliferate, so too does their electric power demand and will need for family batteries, most of which wind up in landfills. To fight waste, scientists are devising new forms of solar cells that can harvest strength from the indoor lights we’re previously employing.

The dominant materials utilised in today’s solar cells, crystalline silicon, doesn’t perform as effectively underneath lamps as it does beneath the blazing sunshine. But emerging alternatives—such as perovskite solar cells and dye-sensitized materials—may confirm to Read More

What It’s Like to Grow a ‘Mini-Brain’ From Your Own Cells

This story appeared in the June 2020 concern as “Out of His Intellect.” Subscribe to Discover journal for much more tales like this.


It is not every single working day that writer Philip Ball is questioned to contribute to scientific experiments — ordinarily, he’s reporting on them as an alternative. But in 2015, scientists from a London-dependent challenge known as Designed Out of Intellect questioned Ball and a several other creatives if they’d participate in their function and then reflect on the expertise. He agreed.

Ball to start with gave a sample, built up of cells from his skin, which
