Description

**ISM RF radiomobile coverage with low VHF antennas @145MHz in urban environment (Saint-Malo)** _**Transmitter:**_ - Baofeng walkie-talkie - VHF in ISM band - CW=145MHz with BW=25kHz - Power = 1 Watt (30 dBm) - omnidirectional monopoly antenna (see in pdf) - coordinates in Lambert-93 / NGF-93 datum (see in pdf) _**Receive:**_ - Spectrum analyzer: RF explorer combo 3G right sma port, noise level=-105 dBm - omnidirectional monopoly 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 (C) GWAGENN 2016 - Jean-François LEGENDRE - Open Data Commons Open Database License (ODbL) www.gwagenn.com "This database is made available under the Open Database License: http://opendatacommons.org/licenses/odbl/1.0/.
