However the biggest attractions at the event will be the new devices with wireless connections. With most people using cell phones, the wireless industry’s growth depends on it. So the event is going to be abuzz with discussion of devices like "smart" meters that report a home's usage of electricity, natural gas or water back to the utility, and to your phone.

"You'll see more things that are 'today' things versus 'tomorrow' things at the show," said Glenn Lurie, AT&T's president of "emerging devices."

AT&T's CEO Randall Stephenson will be speaking at the show. He will be among the other CEOs of Deutsche Telekom AG, parent of T-Mobile USA; Nokia and Vodafone, the British company that owns 45 percent of Verizon Wireless.

Another big theme at the show will be Near-Field Communications, or NFC. This technology is to make cell phones easy to communicate with other similarly equipped phones in a square meter area. Sending and receiving data between two devices is going to be quick and easy. Samsung and Nokia are proponents of this technology.

The NFC also helps phones talk directly to card-swipe terminals in stores, which has set off a race to organize and control the new world of mobile payments.
