Given that on Sunday, when the pre-inauguration concert took place at Lincoln Memorial, people who attended the event sent 10 times the volume of wireless calls, text messages, pictures and videos as on the busiest hour of a typical day, the swearing in of president-elect Barack Obama is expected to give rise to the same result on January 20.

The aftermath of the large volume of calls, messages and so forth were outages that cellphone users have been notified they could  further experience on Tuesday by virtue of Obama’s inauguration as the new president of the United States.

Some estimates have shown that approximately 400,000 people had surrounded the Reflecting Pool waiting for the three-hour concert, while more throngs of Americans were expected to fill the Mall and inaugural parade route within the day.

Consequently, wireless carriers have announced their users that they might experience minor delays and they’ve also urged them to decrease the usage of the networks, although adding that the latter were capable of coping with the volume.

Verizon Wireless spokesman John Johnson stated that the majority of calls through the carrier had been successful on the first attempt, while Crystal Davis, a spokeswoman for Sprint Nextel, said that the network had functioned as expected.

For several months now, the carriers have been preparing to forestall the issues that might arise on inauguration day, whereas Steve Largent, president and chief executive of the Cellular Telecommunications Industry Association, has asked cellphones users to do their part and choose texting over voice calls.
