Good news! Let the age of 5G commence!
"Cellular radios do a lot of switching. They have to switch between transmit and receive, they have to switch between different frequencies to prevent interference, and they may have to switch among signals with different phases to steer their data beams around. RF switches are pretty demanding devices that need a combination of characteristics that are hard to come by."
