Satellites aren’t supposed to fail—but their signals can be jammed, spoofed, or simply weakened by the world we’ve built. We sit down at MWC with NextNav CEO Mariam Sorond to unpack a practical, standards-based path to resilience: using 4G and 5G PRS signals to deliver terrestrial positioning, navigation, and timing that complements GPS and keeps critical systems online when it matters most. Mariam explains how PRS, baked into 3GPP standards, can be activated with a sliver of network capacity and stitched together through multilateration and precise timing. Instead of funding a costly standalone beacon grid, operators and spectrum holders can partner to light up low-band spectrum, upgrade rules, and offer dependable PNT at scale. The result is a network capability with reach across 96% of the population, aligned with carrier infrastructure, and ready for 5G—and beyond into 6G. We explore where this lands first: vertical indoor accuracy for public safety, faster search and rescue, factory-floor robotics that don’t drift, hospitals that track assets across wings, and construction sites that sync people and machines. National security runs through it all, as resilient timing underpins encrypted communications, radar coordination, and mission assurance. Just as important is the human side—MWC’s role in building trust, forging partnerships, and turning demos into deployments as telco innovation and AI reshape what networks can do. If you care about reliability, safety, and the real “killer app” for 5G, this conversation delivers a clear roadmap. Tune in, share with a colleague who works in public safety or critical infrastructure, and leave a review to tell us where resilient PNT should be deployed next @NextNav #MWC #MWC26
