Google Inc (NASDAQ:GOOG) is reported to be creating an experimental wireless network at its Mountain View, California headquarters that covers its HQ’s grounds.

According to a report by the Wall Street Journal on Wednesday, the small-scale network wouldn’t have much range, and it would be incompatible with  iOS and Android mobile smartphones and cellular-capable tablets. The new wireless network could, however, provide coverage for devices built to access certain frequencies, from 2524 to 2625 megahertz.

Last week, Google submitted an application to Federal Communications Commission, asking for an experimental license to work on an “experimental radio service” with a two-mile radius covering its headquarters.

Being no stranger to experiments, Google Inc (NASDAQ:GOOG) is now confident about its new experiment; however, the web search giant declined to share more information with the WSJ on what the company was building the network for.

Although no concrete proof has been received from Google about building a wireless service available for everyone,  rumors have been circulating about Google and Dish holding talks about teaming up to build a wireless service in the past, we can’t help but wonder if Google is working undercover to roll out its next big thing this year.

“Those frequencies, which could work well in densely populated areas, could be important in the future because mobile operators in China, Brazil and Japan already are building wireless networks using them, meaning that compatible devices eventually will be manufactured, said Walter Piecyk, a wireless-industry analyst at research firm BTIG.” wrote WSJ in its report.

Google’s purchase of Motorola Mobility last year can also be connected with the speculations about a possible big thing by the web search giant.

Google Inc (NASDAQ:GOOG) also said that the wireless frequencies that it intends to use in this experimentation are controlled by a wireless broadband provider, Clearwire Corporation (NASDAQ:CLWR). However, Clearwire declined to comment if it was working with Google on the project.
