Progress of building hot spots has been slow: The piece looks at how involved the cellular carriers are in Wi-Fi and how their strategies differ, concluding that confusion surrounding a Wi-Fi business case is slowing down buildout.
Maybe, but from my perspective it looks like the market is moving pretty fast. T-Mobile has thousands of hot spots and Boingo has deals to support 2,600 hot spots, which doesn't include T-Mobile. There are also plenty of small or independent organizations with hot spots. Despite some shutdowns and bankruptcies, the growth seems to be spurting.
