The municipality of Madrid has launched a free Wi-Fi service on buses in the city. The service is immediately available on 60 percent of the approximately 2,000 buses in Madrid, reports Spanish daily El Pais. Excluded for the moment are the older ones, painted red, which the municipality has started replacing. But by April 2011 it will be possible to use the internet free of charge on all buses in the Spanish capital.See this, and also this.
Interestingly, the service is piggy-backing off connectivity needed to support location-enabled scheduling for the bus operator, and is free because it is sponsored. It’s marketed under the slogan “viaja más inteligente, vive mejor” or “travel more intelligently, live better”.
