Your cell phone doesn't always work from the airport, but do you know the reason?
The buzz is that cellular antennas are banned near airports, that air traffic control interferes with the frequencies used by wireless phones, and even that the control tower uses the same frequency as cell phones.
More likely, there are too many users trying to access the same cellular tower, according to John Grotland of GSM wireless service provider Omnipoint Communications. "There could be a bunch of people using the same carrier," he explains.
Then there are the so-called "dead spots" where a cell phone call can't be made, a factor exacerbated by height restrictions of antennas near airports. And some multilevel terminals shield passengers from a mobile phone signal on a lower floor.
George Shaginaw, senior vice president of technology and operations at the Cellular Telecommunications Industry Association, says the industry is concerned about the challenges of making a connection at airports but that carriers are working to fix the problems. "Airports have some unique restrictions, and there's a higher concentration of people," Shaginaw says. "But we're trying to meet the demand from our customers."
