Intelect Corp.RF Engineer support to WMATA (Washington D.C. Subway) Jan-March 2011
Performed RF coverage testing for 490/800 MHz Public Safety bands in subway tunnels in a system consisting of leaky coax, broadband distribution amplifiers, a distributed antenna system, and fiber optic back haul. Measured uplink and downlink transmit/receive signal levels through a revenue generating train into the leaky coax, through the BDAs, and to the RADIO Operations Center via the fiber optic back haul. Researched potential interference via FCC ULS database, performed remediation efforts on RF Noise on the ICAD system in the 800 MHz Public Safety Band by measurement and setting of transmission level points, gains, and attenuator values to optimize the system for “unity gain”.
