At the cellular telecom conference, Craig McCaw said he's targeting international locations for broadband wireless and plans to offer voice over broadband wireless: NextNet, McCaw's equipment vendor, is already selling equipment in locations such as the Ivory Coast, Bangladesh, and remote areas of Canada. McCaw said that he's looking closely at VoIP and said there's "no question" that he plans to offer some sort of VoIP service to customers using services from Clearwire, his operator company. Clearwire currently has a network in Jacksonville, Fla., with plans to offer services in 20 cities in the U.S. and Mexico by the end of 2005.
