• Propagation lab is one of the oldest laboratories of Research Department established in 1937.
  • Carry out field strength measurement & other propagation related studies of MW/FM/DRM/DTT Services of AIR & Doordarshan located in different part of the country.

Present Activities

  • Propagation studies (both in qualitative & quantitative) on analogue broadcast signal(AM/FM/TV) of AIR & Doordarshan Transmitters.
  • Long term measurement on RF broadcast signals for specific purpose.
  • Field Strength Survey for evaluation of various type of interferences on wanted signal & to evaluate protection ratio & building penetration losses under different terrain conditions.
  • Field strength survey work to determine coverage contour for satisfactory reception of the broadcast signal & also to correlates the actual coverage under existing terrain conditions.
  • Propagation studies on digital Radio & Television transmission like DRM & DVB-T₂ etc.
  • Propagation studies on Ku-band DTH transmission & to evaluate rain attenuation caused by rain during rainy season.
  • Comprehensive field strength survey at different part of the country to ascertain any interference on transmitted signal of AIR & Doordarshan by the transmitted signal radiated from any private broadcaster/foreign broadcaster operating either from Indian Territory or from some foreign territory.
  • Assessment of foreign broadcast in all bands in border areas.
