ISM RF radiomobile coverage with low UHF antennas @446MHz in urban environnement (Saint-Malo)

ISM RF radiomobile coverage with low UHF antennas @446MHz in urban environnement (Saint-Malo)

Transmitter :

• Motorola talkie-walkie
• ISM Band in UHF
• CW=446MHz with BW=25kHz
• Power = 0.5 Watt (27 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 UHF talkie-walkies can be used in the zone, a special filtering is proceeding to remove bad data when UHF 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
• My trainee Nathan from UIT of Saint-Malo who helps me during this survey
