..."Think of any traffic artery during rush hour: You have a large number of people who are trying to access it at the same time," said Joe Farren, assistant vice president of public affairs for CTIA-The Wireless Association, a wireless industry group. "It's really no different with regard to wireless networks."
"...What happens where there is an emergency?" asked Scott Midkiff, professor of electrical and computer engineering at Virginia Tech. "This has been a big problem with the voice cellular system. It will probably become more of a problem with text messaging."
..In an emergency, it could be a concern, Cameron said.
"I didn't have a connection using cell phones for several days, and that was really frightening," he said of living in New York after the Sept. 11 attacks. "I didn't talk to my parents for a week and a half."
"It's definitely a really big question mark," said Rajan Shah, who sent his New Year's text messages before the clock struck midnight to beat the rush. "It really makes you rethink technology and whether we are able to be connected through a global catastrophe."
Text messages already use a different transmission system from cell phone calls. There may be a way to differentiate among types of information or to create a separate system for people to use in emergencies.
Farren said emergency networks in place and now being expanded allow emergency service personnel to maintain voice cell phone service in times of need . . .
"In an emergency situation, you really should stay off your phone" if possible, he said.
Emergencies by definition are so unusual that building a full backup network could be cost-prohibitive, Farren said.
"If you're asking everyone to spends billions to billions to build a secondary network, someone's got to pay for it," Farren said.
But the wireless field is constantly changing, he noted. "As innovation continues, I'm sure some of these questions will be addressed."
It's not a strict technology issue, Midkiff said.
"It's people having to think a little bit differently about how you communicate," he said. "Maybe there's a need for some different models."
