As an electrical engineer, I am honestly astounded by how well spectrum has been allocated/shared. It's one of the greatest miracles of the modern era that tens of thousands of antennas can simultaneously jam into a stadium and still have cell service, radio, TV, wifi, walkie talkies, and Bandwidth is scarce because it's limited by physics. There's some minor inefficiencies, but it's generally pretty good, in terms of bits per second per Hertz.
