WiMax gets Ma Bell props
Wireless is cheaper than buying local network access, executive says.
AT&T's chief technology officer Hossein Eslambolchi says WiMax broadband wireless networks are almost certainly in the company's future. Ma Bell spends $8.5 billion a year now for access to local networks. Setting up WiMax systems would be far less expensive, he said. No solid plans announced yet, though.
