"Then it is a matter of us getting enough of a learning curve so we can reduce the truck rolls and begin more self-installation," Hamilton says.
Truck rolls, a reference to the need to have a service provider show up to have service installed, is one of several complications that hit DSL hard. Another DSL barrier has been the restrictive distances between a user and the phone company's central office facility.
For fixed wireless, the main barrier is now perhaps the limit of the number of cities where the technology is available. But the promise of more availability has some corporate IT managers taking note, Morgan Keegan's Threadgill claims.
"A year ago, you heard a lot of companies talking about fixed wireless. Now you are starting to see a lot of companies coming out with business-class products, and that makes people take it seriously," Threadgill notes.
