The 5G signal is a significant upgrade from its earlier cous-ins - much lower latency rates, fairer transmission speeds with higher bandwidth, richer data packets, mas-sive multiple-input multiple outpul archi-tecture, simplified real time vehicle to vehicle communication for crash avoidance/posi-tional reporting, and more consistent airwave propagation. These same characteristics could enhance current surveillance capability and coverage in the air navigation surveillance realm, effectively closing many of the surveil-lance gaps in the current radar and Automatic Dependent Surveillance-Broadcast (ADS-B) service volumes. Gaps in ADS-B (and radar coverage) occur at altitudes up to 10,000 fed (ft), with larger gaps evident as altitude decreases, For instance, at 500 ft Above Ground Level (AGL) altitude, the current ADS-B coverage looks like Figure 1.
