This story profiles an entrepreneur in Miami, Fla., who is single handedly trying out a whole slew of business models, hoping to hit on the most profitable way to build and support hotspots: He has generally found that building hotspots with his own investments doesn't pay off so he strives to convince the venue to fund the build. Still, his most successful effort so far is an apartment building where he paid for the network. He has also tried out gear from different providers, experimenting until he settled on a security and management solution from Lok Technology.
He makes an interesting example of how a small operation can make this business work. He has a general idea of what he thinks works but he's flexible such that each site he builds has a different model, suited to fit the situation. Also, his overhead is low as he has no regular employees.
