Google's mission is to organize the world's information and to make it accessible to anyone. As it turns out, making the internet accessible is almost as difficult as organizing the information. For that reason, Google's Founder Larry Page is in Washington, DC talking with folks at New America. Google wants to make wifi broadband available to everyone not just in the US but, around the world. To do this, Google has proposed using vacant TV channels as well as unused closed cellular networks. Before using either one, Google needs authorization.
Opening these already existing virtual "lines of communication", is still just one step in providing wifi broadband to the world's population. The next step involves the placement of hardware as well as infrastructure that is capable of supporting broadband WiFi even in remote locations. That may sound like a daunting task in and of itself in theory but actually it isn't. In their recent white paper "On Geolocation", Google concludes that none of the issues involved in creating such a network are "particularly challenging".
Google already owns vast amounts of bandwidth in the form of unused, ultra high-speed, fiber-optic or "dark cable". This "dark cable" could easily be used to connect users to "Google ISP" via transmitters broadcasting WiFi. As far as the transmitters are concerned, Google has a number of options ranging from boxes mounted on existing phone poles to vehicles and even airborne transmitters suspended from weather balloons. Under conditions where fiber-optic broadcast range exceeds transmitter capacity, the system switches to communicate via satellite. This type of network could be partially solar powered, easily made redundant and wouldn't depend on infrastructure. In addition to "normal use", this type of network could provide immediate and advanced point to point communications anywhere in the world during disasters. All this, assuming Google is allowed to use a few empty TV channels!
Why is this important to search marketers? In addition to making information available, ads will also be available and in some areas of the world that means for the first time. By providing internet access, Google will be able to provide more relevant results based on the users exact geo-location.
