Looking forward to seeing everyone next week at #IWCE2026, safe travels!

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

Cheers! If you're at #MWC2026 join us right now at the NextNav meeting room for drinks, tapas, and good conversation. 📍Hall 2, 2I16MR

Day 2 at #MWC2026 and the momentum is building. Our team has been busy connecting with industry leaders and diving into conversations around NextNav’s terrestrial 3D PNT tech. Stay up to date on our latest events and announcements: nextnav.com

In less than 1 week NextNav will be at #MWC2026 in Barcelona, hosting meetings in our private meeting room in Hall 2, #2I16MR. Will you be attending MWC this year? If so, we’d love to meet! Book a time with us here: hubs.la/Q044xjWZ0

I can't believe we are only a couple of days away from #NENAGTW and am quite excited to be joining again this year. On behalf of the team at @NextNav we thank you all for what you do, and it is our pleasure to serve!

Looking forward to being part of #IWCE2026!

#MWC26 is just around the corner, and the NextNav team is ready to discuss the latest on our resilient 3D PNT solution! Let's connect: nextnav.com/mwc-2026/

"Protecting PNT is not only a matter of technological investment, but one of national security and economic stability. A robust #PNT system of systems will ensure resilience and send a signal to strategic adversaries.” - @CSPC_DC This is a national imperative.

@RedlineSafety CEO Scott Holman just filed in support of @NextNav’s 5G PNT service, calling the Z-axis capability a “meaningful advancement” for firefighter safety. These advancements highlight when seconds count, 3D precisions saves lives.

If PNT terminology feels like a maze of acronyms, you’re not alone. Our blog breaks down the most important PNT terms—what they mean, why they matter, and how they fit together. Explore the guide: nextnav.com/a-comprehensiv… #PNT #GPS #LearnMore #Guide

Don't miss us this year at #MWC2026 in Barcelona, where we'll be hosting meetings in our private meeting room in Hall 2, #2I16MR. Are you interested in meeting the team and learning more about NextNav's resilient 3D PNT solution? Request a time here: nextnav.com/mwc-2026/

NextNav is pleased to be part of this year's #IWCE2026. @RobClark2020 will be participating on the panel, "Why is Z-Axis So Difficult? Unpacking the Barriers to Reliable Vertical Location for Public Safety", exploring the unique barriers to reliable vertical location, including indoor signal behavior, barometric sensor limitations, device variability, multipath interference in urban canyons, and the absence of consistent integration standards for dispatch and mapping systems. There's still time to register using Rob's speaker code, SPEAKER20: iwce.informaconnect.com/2026/registrat…

NextNav is advancing a solution that is: ✔️ Terrestrial: Provides an earth-based backup and complement to space-based systems. ✔️ Market-based: The only terrestrial option not asking for taxpayer dollars. ✔️ Widescale: Uses existing 5G networks that are already deployed across America. Check out our FCC Insights page for more on our technology, what the industry is saying about GPS vulnerabilities, and our latest filings: nextnav.com/fcc-insights/

We’re excited to share that NextNav will be at #MWC2026 in Barcelona, hosting meetings in our private meeting room in Hall 2, #2I16MR. Will you be attending MWC this year? If so, we’d love to meet! Book a time with us here: hubs.la/Q03_cthm0

NextNav filed a technical response to the recent submissions by Neology and IBTTA/E-ZPass and reaffirmed the conclusions of NextNav’s August 2025 Tolling Coexistence Study, which demonstrated that licensed tolling systems can coexist with 5G-based positioning, navigation, and timing (PNT) operations in the Lower 900 MHz band.
