Explanation

Please explain in the area below why an STA is necessary: Our research involves measuring and modeling the wireless channel in mobile to mobile vehicular environments in the 700-800 MHz band. Currently this part of the UHF spectrum is licensed for commercial television broadcast. We wish to transmit and receive test signals from moving vehicles in unused UHF channels. Based upon our test location and the stations broadcasting nearby, the tests will be performed in the unused channels of 67 and 68 (788-800 MHz).

Purpose of Operation

Please explain the purpose of operation:

The reallocation of the 700-800 MHz broadcast frequencies has opened up the spectrum to new uses for public safety and possible open access whitespace applications. Vehicular communications will comprise a portion of both public safety and open access traffic in the reallocated spectrum. The vehicular environment presents a number of challenges that must be understood and appropriately managed in order to enable reliable wireless communications. Impairments such as multi-path, frequency selective fading, and short coherence times in vehicular communications are much more severe than fixed point to point broadcast situations. We propose to characterize a 10 MHz channel in the 700-800 MHz spectrum in vehicular environments. From these measurements, we can calculate channel model parameters such as spacing and strength of the taps in the multipath model, as well as Doppler, Ricean K-factor, and the signal-to-noise-ratio (SNR). The experiments will be conducted in real road and city environments. Test equipment will be placed in a transmit vehicle and a receive vehicle. Measurements will be conducted while moving through a variety of environments and differential GPS will be used to accurately determine location. The transmitter will broadcast a signal through a roof mounted omni-directional antenna. The sounding waveform will be generated by laboratory signal generator and passed through a power amplifier to provide 20dBm of power to the antenna. The waveform consists of a maximal-length, pseudorandom (MLS) {±1} bit sequence pre-generated in Matlab and modulated via BPSK. The MLS is 511 bits in length and is generated at a rate of 11 MHz. In the waveform, the data sequence is followed by a 511-bit null period and repeated. Following filtering with a root-raised cosine filter, the 3 dB bandwidth of the transmitted signal is approximately 11 MHz. The receiver will collect the waveform with a roof mounted omni-directional antenna and digitize the data using a RF signal analyzer. The data is stored on a laptop for post processing. There will be two locations in Michigan, one covering Ann Arbor, and one covering the FTTA Proving Ground in Fowlerville. The Ann Arbor testing will be centered at 42deg 16 40 N, 83deg 44 00 W and will cover a radius of operation of 5 miles. The Fowlerville testing will be centered at 42deg 36 50 N, 84deg 03 05 W and will cover a radius of operation of 1 mile. The license will request a transmission power no greater than 0.2W ERP, emanating from an omni-directional antenna to be no greater than 8 feet above the ground.
