Greater London Per-Transmitter-Proxy, Per-RAT Simulated Path-Gain Dataset

A city-scale simulated radio-propagation dataset for Greater London, providing per-transmitter-proxy, per-RAT path-gain patterns across receiver surface faces. It supports analysis from individual LTE transmitter-proxy footprints, through multi-proxy spatial comparisons in urban map context, to RAT-specific and city-wide propagation summaries across GSM, UMTS, LTE, and NR. The release contains 449 billion Parquet path-gain records. tx_instance_id denotes a simulated transmitter-proxy hypothesis, not a verified physical base station. Values represent simulated isotropic path gain—not measured coverage, RSRP, RSSI, SINR, throughput, or network performance.
