While 5G mobile networks promise to provide tremendous wireless speeds with low latency, they may also make it more difficult for meteorologists to provide weather forecasts. That's because 5G's neighboring frequencies are used by satellites that detect water vapor in the atmosphere, data that informs weather models used by meteorologists. From Nature:
Astronomers, meteorologists and other scientists have long worked to share the spectrum with other users, sometimes shifting to different frequencies to prevent conflicts. But “this is the first time we’ve seen a threat to what I’d call the crown jewels of our frequencies — the ones that we absolutely must defend come what may”, says Stephen English, a meteorologist at the European Centre for Medium-Range Weather Forecasts in Reading, UK.
They include the 23.8-gigahertz frequency, at which water vapour in the atmosphere emits a faint signal. Satellites, such as the European MetOp probes, monitor energy radiating from Earth at this frequency to assess humidity in the atmosphere below — measurements that can be taken during the day or at night, even if clouds are present. Forecasters feed these data into models to predict how storms and other weather systems will develop in the coming hours and days.
But a 5G station transmitting at nearly the same frequency will produce a signal that looks much like that of water vapour. “We wouldn’t know that that signal is not completely natural,” says Gerth.

A spokesperson for the Facebook-owned WhatsApp says the company has fixed a security vulnerability that let hackers take control of the messaging app by way of a malicious GIF.
Last month, a developer called Axi0mx released an Iphone crack called Checkm8, which attacks a defect in the Ios bootrom, a low-level piece of code that has not been successfully attacked since 2010. The bootrom is read-only, making its defects effectively unpatchable, short of removing the chip and swapping it for one with more robust […]
Most people don’t spare a lot of thought on the potting for their plants. Perhaps something with a color that matches the walls, but that’s as far as it goes. After all, the plants don’t care what they’re wearing. Do they? Actually, they might. As eye-catching as the AIRSAI Floating Bonsai Plant Pot is, its […]
With the gains real estate has made over stocks in the past 25 years, it’s easy to see why the rich constantly use it to expand their wealth. What’s slightly less obvious is why only the rich seem to ever break into real estate investment. There are a lot of reasons, but a couple of […]
