Sharing Critical Frequencies does not work!
The real problem is combining over-the-air use of frequencies with stuff that's supposed to stay within the cable system. It shouldn't be news to anyone that rf does not stay inside the cable system - it leaks out and interferes with all kinds of over-the-air transmissions, including police, fire, ambulance, aviation safety and now medical services.
They all need to be on separate, discrete frequencies, and if that means taking away some opportunity to watch Judge Judy on forty different channels, so be it. People that tell you low powered in-house systems can co-exist with over-the air systems are just lying to you. Ever tried to watch cable channel 18 near a 150 MHz region paging system?
