Do you know how many batteries will be needed for 8 hours of back up power? With todays technology 8 hour back up will double or triple the size of a cell cabinet. I can barely get my laptop to work for 2 hours unplugged and it uses half a percent of what a small cell cabinet uses.
I didn't say it required 8 hours of Battery backup. Just backup. To me that suggests more that it would require a Generator with at least 8 hours of fuel.
That would be a pretty expensive proposition for every cell tower, however. -- "Fascism should more properly be called corporatism because it is the merger of state and corporate power." -- Benito Mussolini
