Forget the old ship-to-shore phone. Today's cruise lines are wired, wireless, and completely connected.
Ever since Odysseus steered for Troy, ships at sea have been isolated satellites of human endeavor, cut off from the shore and the ever-pressing demands of everyday, dry-land existence.

But soon, all that will be ancient history.

In just a few short years, the telecommunications revolution has seized command of nearly every cruise ship - from cutting-edge stem to luxury stern. And with new advances coming at a dizzying speed, the key decisions aren't so much whether passengers can call anywhere, anytime, or click online at anyplace onboard, but whether protocol demands that at least some of the communicating be limited to discrete locations so as not to disrupt passengers who are happy to leave it all behind.

Welcome aboard, for example, the newly commissioned Carnival Valor, 110,000 tons of fun that hosts nearly 3,000 passengers (based on double occupancy). Every square inch of its staterooms, cabins, bars, and deck chair space has wireless Internet access. Carnival Cruise Lines is also negotiating with wireless-service providers to make it possible for every brand of cellphone to call anywhere in the world from its ships.

"Once, one of the attractions of the cruise was to get away from it all," says Carnival's Jennifer de la Cruz. "Thirty years ago, you had to go to a radio room to make a call. But things have changed. The fact is that people want to stay connected via e-mail and via phone."
