Here is the abstract of the patent: "Methods and systems for providing routing information to a user are disclosed. Based on a request for routing information between an origin and destination for a travel objective, wireless coverage data for the geographic area associated with the travel objective is received. A graph model for determining routes between the origin and destination is adjusted based at least in part on the wireless coverage data. According to particular aspects of the present disclosure, the graph model can be adjusted based on the wireless coverage data and at least additional parameter such as estimated trip time, average speed, distance, favored routes or traffic information. User information can be optionally provided and used to emphasize or deemphasize wireless coverage data in the determination of the route for the travel objective." A post from Android Authority explains the patent thus: "Lets break this down. According to the USPTO, the patent is much like GPS. It involves finding the destination and current location. However, the location and route to the destination can be altered by wireless coverage. In other words, Google can now use your cell signal to help better figure out where you are and where you’re going." However in the comments someone seems to correct the description given by the author: "This is a patent for creating a path from A to B that uses "cell phone coverage" as a factor. So you know how on Google Maps, there's a checkbox for "Avoid Toll Roads"? Google can now have an option for "Avoid Areas Without Reception"." Interesting patent. Aside from Google Maps, I think this will also tie in with Google Now to improve it's location based cards such as the time and route to your home/work or meeting as well as nearby locations and attractions. What do you think?
