Cell service during emergencies

I believe PUC has authority over cellular services in Colorado, and this comment is related to the public safety power shutoffs. When power is shut off during weather emergencies, and home wifi networks no longer work, it's critical that residents have reliable cellular service to receive communications. I live in a residential neighborhood within the city limits of Boulder, and my cellular reception is terrible (I've had both Verizon and T-Mobile, and both are equally bad). This is not an issue when wifi is working, but is a critical safety issue when power goes out. PUC should investigate the adequacy of cellular reception in residential areas to ensure critical communication is available when power is shut off.
