"(The Hearst Tower) is also one of the more technologically advanced office buildings in the country. Almost everything is automated, from the lighting to the two-story waterfall in the lobby. Employees and visitors can also use their cellphones, BlackBerrys and wireless laptops anywhere in the building’s 46 floors, including the lobby and cafe. Employees have access to all the applications and network services they would have if they were sitting at their desks.
At first glance, that may not seem a big deal. Yet in many office towers — as many people who’ve tried to get a cellphone signal on upper floors can attest — heavy construction materials impede radio frequency signals, resulting in weak signal coverage in parts or all of a building. To compensate, many buildings have sprouted a costly tangle of antennas and cables for the various devices, which use different wireless technology standards and spectrum bands. But that can create interference and the headache of installing cables and antenna for each new service."
