A passenger train located in a station is connected to an access point (AP) mounted on the roof of the station. RF propagation paths computed using the shooting-and-bouncing ray technique are shown. These ray paths arrive at a receiver (Rx) antenna after they reflect and diffract from the environment, where each reflection surface attenuates the signal uniquely due to varied conductivity and permittivity material properties. Wireless InSite’s built-in Communication Systems Analysis tool provides RSSI and SINR for various IEEE standards from 100 MHz to 100 GHz.
- Model RF-CBTC channel and effects of multipath inside tunnels
- 3D deterministic simulation accounts for position and impact of surrounding clutter
- Signals are predicted using SBR techniques including propagation inside train car
- Account for blockage from passengers and interference from access points
- Include effects of arriving or departing train from station on RSSI for WiFi, LTE and 5G NR
