Revealing the Best and Worst Mobile Experiences at East Coast Beaches in the U.S.

When it comes to mobile connectivity, coverage maps often look impressive on paper. Streets and highways light up with strong signals, giving the impression of blanket coverage. But step inside a busy airport terminal, a sprawling mall, or a corporate campus—and the story can change dramatically. Indoor connectivity remains one of the toughest challenges for mobile network operators. Crowds of people, thick walls, complex building layouts, and overlapping cell coverage all contribute to weak signal quality. For users, it means dropped calls, slow apps, and frustrating experiences. For operators and venue owners, it means missed opportunities. This is where M2Catalyst’s Crowd SiteIntel (CSI) delivers a fresh perspective—making indoor signal problems visible, quantifiable, and fixable. Indoor vs. Outdoor: How CSI Filters Signal Quality Traditional coverage studies don’t always distinguish between outdoor and indoor conditions. Yet, the difference is critical. With CSI’s indoor/outdoor filter, decision-makers can separate signal quality readings inside buildings from those collected outdoors. This allows operators to: Pinpoint specific structures where RSRP, RSRQ, or SINR degrade sharply Compare indoor vs. outdoor performance across the same area Quantify user experiences within malls, airports, train stations, and corporate campuses Instead of vague assumptions about indoor coverage, CSI provides polygon-level building insights—a powerful way to identify where customers struggle most. Identifying Coverage Gaps in Complex Indoor Environments Crowdsourced measurements from over 200 countries reveal consistent pain points: Airports: Even in some of the world’s best airports, terminals often have “shadow zones” where SINR drops dramatically. Travelers expecting seamless connectivity often get lag instead. Shopping Centers: Multi-floor malls with concrete cores and underground sections are notorious for signal gaps, especially in parking garages. Corporate Campuses: Even world-class offices experience poor indoor RSRP in conference halls, impacting collaboration and productivity. Hospitals & Healthcare Facilities: Thick walls, shielding materials, and sprawling layouts often block signals. Yet these are high-stakes environments where connectivity is essential for staff, patients, and visitors. Universities & Schools: Large campuses with multiple buildings often show poor indoor RSRP in lecture halls, libraries, and dormitories, impacting both staff and students. Sports Arenas & Event Venues: Stadiums and arenas pose extreme challenges due to user density, resulting in poor SINR and data congestion. Hotels & Resorts: Multi-floor layouts, basements, and conference areas often create blind spots—critical for business travelers and events. Transit Hubs: Subway stations and train depots frequently act as coverage blind spots By mapping these environments, CSI allows operators and infrastructure partners to prioritize upgrades where they matter most: high-traffic indoor venues where network demand peaks. Fixing Indoor Coverage: Small Cells, DAS, and Beyond The good news? Indoor coverage issues are solvable—if you know where to look. Armed with CSI data, RF engineers and planners can determine whether an area requires: Small Cells to boost coverage in targeted zones Distributed Antenna Systems (DAS) for large, complex buildings Wi-Fi Offloading strategies to support high user density Because CSI pinpoints problems down to the building polygon, operators can deploy infrastructure precisely—reducing wasted spend and improving ROI on network investments. A Win-Win for Enterprise Customers Solving indoor connectivity isn’t just a technical win—it’s a business win. Enterprise Sales Teams can use CSI insights to target B2B opportunities, approaching venue owners and corporate clients with clear data on their pain points. Venue Owners benefit by providing better customer experiences—stronger signal means longer dwell time, better tenant satisfaction, and more revenue. Operators gain by improving network quality in high-value locations, enhancing customer loyalty while reducing churn. Indoor connectivity has long been seen as a headache. With CSI, it becomes a competitive advantage. Conclusion As mobile usage shifts increasingly indoors, the ability to diagnose and solve indoor signal problems is no longer optional—it’s essential. Crowd SiteIntel puts building-level visibility into the hands of operators, engineers, and business teams alike. By mapping the world’s largest malls, airports, and campuses, CSI reveals the gaps that matter most—and empowers the industry to close them faster. In short, better insights mean better experiences. And nowhere is that more important than the places people spend the most time—indoors.
