Nissan Technical Center – North America, Inc. 39001 Sunrise Dr. Farmington Hills, MI 48331 October 31, 2007 Federal Communications Commission Office of Engineering and Technology Experimental Licensing Branch 445 12th St., S.W. Room 7-A322 Washington, DC 20554 Dear Sir or Madam: We would like to submit this exhibit as a narrative statement describing in detail the purpose of our Request for Experimental License under the FCC Experimental Radio Station Authorization. Nissan Technical Center - North America, Inc. (NTCNA) is the North American engineering center for Nissan Motor Company. Ltd. (Nissan). NTCNA is responsible for the testing and development of navigation systems installed into all Nissan vehicles sold in the United States. As part of this testing & development, NTCNA needs to evaluate the GPS reception and performance for both new & existing navigation systems. Our experimental test plan is to first re- radiate GPS signals inside the NTCNA facility, causing the test vehicles to receive the correct GPS signal inside the specific testing area. Upon vehicle reception of these signals we can confirm navigation system performance & quality as related to: • Antenna performance • Setting the clock via GPS signal • Locator performance • Routing performance. It is required to conduct these tests inside our facility since most of the vehicles we evaluate are confidential in nature and can not be driven outside except under tight security measures. In addition, we have confirmed the maximum equivalent isotropically radiated power (EIRP) to be less than the specified -140 dBm/24 MHz, as received by an isotropic antenna at a distance of 100 feet from the building where the test is conducted. These signal calculations were derived from the 2 sources listed below: A) Link budget calculation by NAVTECH GPS Supply http://www.navtechgps.com/pdf/GpsNetworking_LinkBudget.pdf & B) A presentation made by president of GPS Networking Steven Waite http://www.ntia.doc.gov/osmhome/irac/gps_networking_irac_presentation.ppt We appreciate the consideration for application for the Experimental License. Should you have any further questions, please contact me at the number listed below and I will be glad to provide any additional information you may need.
