Cell Phone Companies Warn of Delays During Inauguration.

First, Inauguration planners warned there were no rooms left. Then they predicted roads and subways would be overwhelmed by the crush of visitors.

Now, wireless companies are telling customers to expect delays and dropped calls during the swearing-in.

Wireless industry spokesman Joe Farren says the infrastructure that cellphone carriers rely on will face the same pressures as its brick and mortar counterparts on Inauguration Day. He says cellphone carriers will be bringing in mobile towers and trucks to boost wireless capacity, but there is a physical limit to how many calls can go through at one time. Farren has a few simple rules for inauguration: text, don't talk and hold off on sending any cellphone pictures.
