The San Francisco Marathon™ Teams Up with Skyhook – New SpotRank map will display social activity and real-time population density along the course

SAN FRANCISCO, CA – July 22, 2010- Skyhook Wireless®, the worldwide leader in location positioning,
context and intelligence, and The San Francisco Marathon™ today announced a collaboration to deploy a realtime map of geotagged mobile activity around the Marathon on Sunday, July 25.

The map is live today at:

Skyhook’s system is used to determine location on tens of millions of mobile devices and process millions of
location requests on its network every day. The San Francisco Marathon™ map uses Skyhook’s data
intelligence service SpotRank, a measure of real-time population density based on location requests on
Skyhook’s network. While SpotRank lets spectators view hotspots of activity along the Marathon route, the
map also displays what people are saying on Twitter, look at pictures through Flickr, and view Foursquare
check-ins all in a custom interface.

"Skyhook’s SpotRank map for The San Francisco Marathon allows us to provide a unique view into how the
city of San Francisco adapts to the race,” said Lyz Luke, media coordinator for The San Francisco Marathon™.
“The map creates a unique online hub for where spectators from all over the world can experience the
excitement of the Marathon.”

“We are just beginning to tap into the power of location intelligence,” said Kate Imbach, vice president of
marketing for Skyhook. “The Marathon map is just one illustration of how location data, tied to the context of
mobile social activity, can give us a new level of insight into the events happening around us.”
