How 5G Cell Service Could Hurt Weather Forecasts

TL;DR

The FCC's plan to let cellular carriers use radio frequencies close to those used by weather satellites for 5G transmissions could interfere with weather measurements, setting forecasts back by decades.

Transcript

[♪ INTRO] For all that we complain about weather forecasts, they’re actually pretty amazing. A 5-day forecast today is about as reliable as a 24-hour forecast was in 1980. It’s not just about the convenience of having your umbrella, either. Good weather forecasts save lives. Hurricane forecasts, for example, can give people days instead of hours to... Read More

Key Insights

• ☀️ Weather forecasts are valuable in saving lives by providing advanced warning and preparation time for dangerous weather events.
• 🚄 5G technology aims to improve phone connectivity by using higher-frequency radio frequencies, which offer faster speeds and increased capacity for data transmission.
• 🧡 Higher-frequency radio frequencies have historically been avoided due to engineering challenges and limited range.
• 😚 The critical frequency for weather forecasting (23.8 gigahertz) is close to the band (24.25 gigahertz) that cellular carriers want to use for 5G transmissions.
• 🤽 Concerns arise from the potential interference from 5G transmissions on weather satellite measurements, particularly in relation to water vapor data.
• 🤕 The FCC's current guidelines on spillover limits are higher than what other countries recommend for this frequency band.
• 📲 Scientists are calling for tighter limits on spillover to minimize the potential interference between 5G transmissions and weather satellite measurements.

Questions & Answers

Q: How do weather forecasts play a role in saving lives?

Weather forecasts provide crucial information that gives people time to prepare and evacuate in case of dangerous weather events like hurricanes, ultimately saving lives.

Q: Why are meteorologists concerned about the FCC's 5G plan?

Meteorologists are worried that the 5G transmissions could interfere with weather satellite measurements if the off-target noise from 5G transmitters bleeds over into the critical frequency used for water vapor measurements.

Q: What are the advantages and disadvantages of higher-frequency radio frequencies used in 5G?

Higher-frequency radio frequencies allow for faster speeds and increased capacity for data transmission. However, they have limited range and are easily absorbed by obstacles like buildings, trees, and even rain and fog.

Q: How might interference from 5G transmissions impact weather forecasts?

Interference could lead to a loss of microwave data used to measure water vapor, which is a crucial variable in weather forecasting. This could set weather predictions back by 40 years and reduce the accuracy of forecasts.

Summary & Key Takeaways

• The FCC's plan to allow cellular carriers to use radio frequencies close to those used by weather satellites for 5G transmissions is causing concern among meteorologists.

• 5G technologies promise faster and more reliable phone connections by using higher-frequency radio frequencies, but these frequencies have historically been avoided due to engineering challenges and limited range.

• The critical frequency for weather forecasting (23.8 gigahertz) is close to the band (24.25 gigahertz) that telecoms want to use, raising concerns about potential interference and the loss of important weather data.
