It works like this: within every telecom network, there are microwave links that operate in the electromagnetic spectrum. If rain is passing through the path of the microwave link, a minor decrease in the signal occurs. It doesn’t have any effect on the data transmission, but this little change makes it possible to know exactly where rain is falling. And now, with the heavy build out of mobile networks, we can explore using this anomaly as a key competent in local weather radar.
As it is now, precipitation data is the most resource intensive information to gather – yet there are many millions of these microwave links deployed around the world, creating a dense, data-gathering network.
By adding low cost sensors to monitor temperature, pressure, and wind we can create a detailed set of weather data that is analyzed, and acted upon.
It effectively means that people and business can get information that can be used to minimize the impact of weather.
