Google's hush-hush about its proposed wireless network project at its Mountain View campus has only spiked the curiosity that led to various rumors on what the search giant is actually experimenting on.

Google is certainly trying to create an experimental wireless network covering its Mountain View, Calif., headquarters. According to The Wall Street Journal, analysts believe that the move would signify the creation of dense and superfast Google wireless networks in other locations allowing people to connect to the Web using their mobile devices.

The news about Google's experimental project began circulating in the Web world after the Internet titan filed an application with the Federal Communications Commission seeking an experimental license for a non-broadcast 'experimental radio service.'

Google's small-scale wireless network would use frequencies that are not compatible with any of the mobile devices available in the market today including Apple's iPad or iPhone or other devices powered by its own Android operating system.

Google said it will place base stations to experiment the service in its headquarters. The specific building selected for the testing also houses the Google Fiber team, the WSJ report said. Google Fiber team is a part of the Google Access unit which rolled out the remarkably fast fiber-optic network in Kansas City and a Wi-Fi network in New York.

Digging out the application, Steven Crowley, a wireless engineer revealed that permission is sought to test frequencies across the 2524 to 2546 MHz range and 2567 to 2625 MHz range. These frequency ranges are reserved for Educational Broadband Service and Broadband Radio Service. According to the application, Google plans to use the wireless frequencies that are controlled by Clearwire Corp., a wireless broadband provider. "That means the frequencies are part of what's called "licensed spectrum" and can be more reliable than Wi-Fi. Wi-Fi is unlicensed, meaning it can be used by anyone," the report said. It should be noted that the search giant does not have control of licensed spectrum currently.

It is not clear at this point whether Google would come up with a service to consumers or just build such a service for internal use only. It's highly speculated that Google would introduce a potential wireless service offering for consumers of its Google Fiber product. If that is to happen, residents of Kansas City who had signed up for Google's high-speed Internet would receive a wireless service throughout the city for devices of the future which would be compatible with the network.
