RF Propagation & Coverage SimulatorLIVE
Log-distance path loss model. Set frequency, TX power, antenna height, and environment (free space/urban/indoor/dense indoor). Shows RSSI contours at -70/-85/-95 dBm and coverage radius for minimum signal threshold.

DAS Signal Chain SimulatorLIVE
Trace a DAS cascade from donor antenna to remote antenna. Configure BDA output power, splitter count/loss, cable type and run length, and indoor antenna gain. Shows dBm at every node with NFPA 1221 pass/fail verdict.

BDA Coverage & Gain Sizing SimulatorLIVE
Simulate BDA coverage on a multi-zone floor plate. Assign donor RSSI, BDA gain, cable and penetration losses, interior antenna EIRP per zone. Each zone shows inbound/outbound RSSI with IFC 510 / NFPA 1221 compliance verdict.

NFPA 1221 / IFC 510 Coverage SimulatorLIVE
5ร—5 grid of test points per NFPA 1221 Section 9.6 / IFC 510. Configure donor RSSI, BDA gain, cable loss, and penetration loss per zone. Shows inbound/outbound RSSI, pass/fail per point, and overall coverage percentage toward 95% target.
