MILLIMETER WAVE EMERGENCY COMMUNICATIONS

THE RESEARCH PROPOSED INVESTIGATES THE FEASIBILITY OF SMALL MILLIMETER WAVE RADIOS WITH SERVO DRIVEN ANTENNAS FOR EMERGENCY LINE-OF-SIGHT COMMUNICATIONS FOR BOTH GROUND-TO-GROUND AND GROUNDTO-AIR USE. THE CONSIDERATIONS IMPACTING DESIRABILITY OF THE CONCEPT INCLUDE THE SEARCH MODE METHOD, DATA CAPACITY, MODULATION METHODOLOGY, OPERATING FREQUENCY, COST, SIZE AND WEIGHT. TRANSMISSION RANGE IS TO BE STUDIED BASED ON ACHIEVABLE POWER LEVELS WITH STATE-OF-THE-ART DEVICES, ATMOSPHERIC PHENOMENA, EFFECTS OF TERRAIN AND FOLIAGE, AND ANTENNA POLARIZATION. THE DESIRABILITY FOR LOW PROBABILITY OF INTERCEPT REQUIRES OPERATING NEAR THE 60 GHZ OXYGEN CONTINUUM, WHICH FURTHER CONSTRAINS MAXIMUM TRANSMISSION RANGE. THIS STUDY INVESTIGATES RELATIONSHIPS BETWEEN EQUIPMENT PARAMETERS AND THIS MAXIMUM TRANSMISSION DISTANCE.
