In an application to the US Federal Communications Commission (FCC) on Monday, tech giant Google requested permission to conduct a series of exploratory tests in California across different wireless spectra. Of particular interest is a rarely used millimeter-wave frequency. This frequency is capable of transmitting vast amounts of information through the air. This new technology could then marry the speed of Google Fiber to improved high-speed wireless services.

The test, if approved, will run on three sites in California’s San Francisco Bay area. The filing says that tests will be conducted in the 5.8GHz and 24.2GHz frequency, as well as the millimeter wave bands of 71-76GHz and 81-86GHz, and will be based on narrow-bandwidth transmissions.

According to the application, the tests could signal the creation of the base technology for use in high-speed, wireless connectivity. This is a part of Google’s plan to extend its reach in the Internet service provider industry. If so, this would completely remove the need for underground cables or fiber. A fast broadband service beamed into our homes could act as an extension to Google’s slowly expanding Fiber service, which offers up to 1 gigabit in upload and download speed. However, laying the groundwork for such a service is a slow process.

The filing is for a 180-day test of wireless frequencies for transmitting data. Google Access and Energy division chief Craig Barratt said the testing period will provide “valuable insight into Google’s technology innovations and potential business plans and strategy.” Though much of the application is redacted in order to protect the confidential data being tested, the tech giant states that the purpose of the test is to “expeditiously test radios in a way that is likely to contribute to the development, extension, expansion or utilization of the radio art.”
