Weather impacts almost everything we do. Severe weather can cause disasters, but also smaller daily weather changes have great impact on people and industries. Using microwave links that are part of mobile communication networks, local weather can be registered much faster and therefor relevant actions can be taken sooner.
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.
