Please explain in the area below why an STA is necessary:
To conduct for a limited period the operations described in this request.

Purpose of Operation
Please explain the purpose of operation:  Conduct experiments using test vehicles equipped with automatic cruise control radars in a manner that extends the sensing range of the radars when a vehicle is not in motion. Google is developing advanced driver assistance systems with the goal of improving the safety and convenience of vehicular transportation. Each Google test vehicle contains several off-the-shelf automatic cruise control (ACC) radars certified for use in the 76.0-77.0 GHz band. These radars are used to sense the environment around the vehicles. The purpose of the requested special temporary authority is to allow Google to conduct experiments using test vehicles equipped with ACC radars in a manner that extends the sensing range of the radars when a vehicle is not in motion. Several ACC radars will be mounted on test vehicles and the vehicles will be driven through a variety of traffic situations, including along freeways and urban surface streets and through complex intersections. The radars will operate at a radiated power of 60 uW/cm^2 at 3m (i.e., the current in-motion criterion) both while the vehicles are in motion and stationary. Because the power will not exceed the current in-motion criterion, Google believes the experiments will not increase the likelihood of harmful interference to any user. Testing the vehicles? performance in complex traffic situations (for example, when the vehicle is stopped at intersections, or when a vehicle is about to make a right turn on to a busy road, in which case the range of a left-sensing radar must be sufficient to inform the vehicle to allow high-speed traffic to pass before proceeding) will provide critical data that will guide the development of more effective driver assistance technology. The results of these experiments will inform the need for a longer term experimental license. The location of the proposed experiments will be the San Francisco Bay, California area, extending south to Santa Cruz, California and north and east to South Lake Tahoe, California. Google intends to conduct the experiments for a six-month period starting from the grant of authority, which we anticipate will occur on or about March 24, 2011.
