"Green" building windows can block cell signals
Eileen Bridges, a senior vice president for strategic planning and technical architecture at Bank of America, said the bank has discovered that energy-efficient windows in its newer buildings are blocking cellular phone signals. Computerworld reports.
"As a result, the bank faces paying premium access charges to wireless carriers to enhance indoor cellular signals, Bridges said. She spoke yesterday at a panel discussion on wireless technology at Mobile & Wireless Enterprise 2008.
With more than 15 buildings in Charlotte, where the bank is headquartered, the three buildings designated as green are the ones where the cellular signal problem has been detected, Bridges said.
... Several analysts and IT managers at the conference said they had never heard of the problem before, but Bridges said the interference has been linked to a special doping material used in the manufacturing process."
