When Hurricane Katrina assaulted the Gulf Coast in 2005, wind and flooding knocked out hundreds of cell towers and cell sites, silencing wireless communication just when victims and emergency crews needed them.
To avoid similar debacles, the Federal Communications Commission wants most cell transmitter sites in the United States to have at least eight hours of backup battery power in the event main electrical power fails, one of several moves regulators say would make the nation's communication system stronger and more reliable.
Two and a half years after Katrina and eight months after the FCC's regulations were released, the two sides are still wrestling with the issue.
