Many proposed regulations are struck down before they become required regulation. Just like the FCC mandates that POTS and fiber have guaranteed battery, the FCC will mandate that cellular towers do the same. This is inevitable. The telco industry is notorious for litigating to death anything that will require an increase in operational expenses but inevitably when a service is deemed to be critical to society it has to comply. On a personal note, when I worked in telecom I never once saw a cell tower that was down due to power loss. Every tower I have worked with had some form of power generation, be it natural gas or diesel. In addition, as a cellular service consumer I have also never experienced an outage due to cellular tower power loss. phb What about the cell site? See
