Inauguration Visitors May Overload Cellphone System

When President-elect Barack Obama takes stage in a few weeks to deliver his inauguration address, no doubt many of the estimated 2 million people expected to gather on the Mall will simultaneously hold their cellphones aloft to snap and send photos, call friends and family, and send text messages like, "omg, yes we did!"

But please don't, wireless network operators say.

For months, the carriers have been preparing for a predicted explosion of cellphone traffic during inauguration weekend as millions of visitors are expected to gather in the Washington area for festivities. Wireless operators say they plan to boost capacity at cell sites on the mall, along the Beltway and underground on Metro so that more calls can be placed at the same time. By the time Jan. 20 arrives, they will have spent millions of dollars to add staff for the event, rolled in extra cell towers on truck beds and expanded bandwidth on wired parts of their networks.

Even with those plans in place, they predict some hiccups.

"You can add hundreds of thousands of lanes to a highway, but if millions of people go for a drive at same time, you can still have a jam," said John Johnson, a spokesman for Verizon Wireless. "There are just so many unknowns."

The preparations for mobile devices are as much of a priority for District inauguration planners as coordinating Metro rail and bus schedules and bringing in enough portable toilets. For Obama, who used the Web and text messaging to fuel his campaign success, it will be the first inauguration in which cellphones are as ubiquitous among youth and professionals as they are among boomers and soccer moms.

Since the 2005 inauguration, the number of cellphone users in the nation has increased by 26 percent, to 262.7 million. And those users are not just talking: They are posting video from their phones to social networking sites such as Facebook, sending text messages to multiple phone numbers at a time and snapping and sending photos with a few keystrokes.

"This is a unique situation that has never happened before -- to have this kind of population increase in one particular area at one particular time," said Joe Farren, a spokesman for wireless trade group CTIA.

Calls by emergency responders such as police, firefighters and medical crews aren't expected to be delayed or dropped by congestion because they will have priority over subscribers. Responders' phones and other devices should be interoperable, said Malcolm Wiley, a spokesman for the Secret Service, so problems communicating with one another -- as was the case during the Sept. 11, 2001, attacks on the World Trade Center -- are not expected.

Mall visitors seeking emergency medical or law enforcement help shouldn't have trouble getting through either, carriers said, as calls placed to 911 from cell phones will also get priority.

But to avoid congestion for regular users, the carriers offer the following tips:
