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
