San Diego will soon have a 5G wireless network system thanks to major companies like Verizon, AT&T, and Qualcomm working to establish it. With 5G, speeds will be 20 times faster than what is possible on current 4G and LTE systems. “Speed is everything,” said Mayor Kevin Faulconer. “And it is going to fundamentally change how we use the internet.” But experts are concerned the frequencies on the broadband spectrum needed for 5G will interfere with those used for weather forecasting.
