Device and transmit signal description: We would like to obtain a license to operate a new device we have developed at MIT. The device operates at 915 MHz band. The device transmits a sine wave (carrier signal) at 915MHz for period of 3x20us every 1 second. In another word, the device is transmitting three times for 20us and it is silent for the rest of one second. Location description: 2-6 devices will be placed on light poles in Vassar Street, Cambridge, MIT. Antenna description: Omni directional or directional patch antennas will be used where the direction of beam will be toward the road. Peak and Average Power: FCC part 90, subpart M: - The device transmits a 30W peak ERP during the 20 us. - The average ERP will be 1.8mW (i.e. 30W*60us/1s=1800uW=1.8mW).
