This is marketing hype poorly disguised as a news story. The whole article reads like it was copied verbatim from a press release for large scale wireless network solutions. It begins:

Panera bread is held up as a great success story for this technology. The only mention the article makes about Panera actually being the largest wi-fi provider is the following:

So what Slashdot, we are to believe that Panera is the largest provider because their head marketing troll says so? Jesus, have a little journalistic integrity.
