When Businesses Install WiFi Networks for Customers, Nearby Competitors May Benefit as Well
Martin O'Donnell pointed out this interesting article from The Seattle Times that explains how Tully's Coffee "borrows" wireless Internet access service from Starbucks. It is able to do this because it has "pursued a real-estate strategy of opening stores close to Starbucks outlets" and WiFi service leaks from those locations to the immediate surroundings including, in some cases, Tully's Coffee bars.
This is one of the better illustrations we've seen of the unintended consequences of installing public access WiFi networks for use by a business' customers.
