ISM RF radiomobile coverage with low VHF antennas @145MHz in urban environnement (Saint-Malo)

Description

ISM RF radiomobile coverage with low VHF antennas @145MHz in urban environnement (Saint-Malo)

Transmitter :

  • Baofeng talkie-walkie
  • VHF in ISM band
  • CW=145MHz with BW=25kHz
  • Power = 1 Watt (30 dBm)
  • omnidirectionnal monopole antenna (see in pdf)
  • coordinates in Lambert-93 / NGF-93 datum (see in pdf)

Receiver :

  • Spectrum analyzer : RF explorer combo 3G right sma port, noise level=-105 dBm
  • omnidirectionnal monopole antenna (see specification in CSV section)
  • all data less than noise+3dB (i.e. -101 dBm) are removed in files

Roads :

  • town of Saint-Malo in France
  • about xxx points
  • about 150 kms
  • in order not to be pertubated by intermodulation, as other VHF talkie-walkies can be used in the zone, a special filtering is proceeding to remove bad data when VHF radio coexistence occurs

Special thanks to :

  • The Major of Saint-Malo that permits this survey
  • OpenData service of Saint-Malo City Council for numerical terrain model used by Gwaves simulation
  • Simulation uses LIDAR data (IGN 2011), building digilitalisation made by Gwagenn with satellite photos
  • DME build with Global Mapper v17
  • My trainee Nathan from UIT of Saint-Malo who helps me during this survey
