Public Wi-Fi Hotspots Grow 400% In 5 Years; Freelancers Rejoice

It’s easier than it’s ever been to get out of the house and away from the houseplants, since public wi-fi hotspots have exploded in the past five years from approximately 50,000 in 2004 to 258,000 in June 2009.

JiWire’s recently released Mobile Audience Insights Report has even more good news for mobile office workers. More than 10 percent of wi-fi users are using cafes as second offices, and most of those users are in a desirable demographic (affluent males 25-49 who plan to buy big-ticket electronic items).

This is just speculation, but if cafe Wifi users are desirable to advertisers and if sending ads through your wifi connection based on your location becomes commonplace then why wouldn’t wifi networks start aggressively trying to get into more places? If, say, Boingo (or JiWire, of course) can sell that many more ads then why wouldn’t they want to be where the pickings are good?

This can only be good for mobile workers.
