MESA, Ariz. (AP) _ A public safety building constructed to withstand a terrorist attack has a built-in snag: its workers are having trouble communicating.

The brand new $46.6 million building in Gilbert is wreaking havoc with pagers and wireless telephones.

Police officers who moved into the building in July have had to use traditional phones, after they noticed problems receiving and sending pages or wireless calls.

Sgt. Jeff Esslinger said the department is having to retrain its workers to be less dependent on the devices.

The building contains offices for the police and fire departments, the prosecutor's office, the Maricopa County justice court and the town's municipal court.

Officers have noted weak cell phone reception in some areas, and a large dead spot in the center of the building, Esslinger said

It doesn't seem to affect workers in other parts of the building, he said.

No one knows why parts of the building seem to block wireless signals.

``It probably won't be solved,'' Esslinger said.
