Digital infrastructure points

• Network coverage and spectrum
  • Countywide 4G LTE and broad 5G coverage across populated areas from AT&T, T‑Mobile, and Verizon.
  • Mid-band 5G (2.5 GHz n41 for T‑Mobile; C‑band 3.7 GHz and 3.45 GHz for Verizon/AT&T) is live along I‑4, SR‑417, US‑17/92, and major commercial districts, enabling materially higher median speeds and capacity vs. LTE.
• Densification
  • Dense macro-site grid along I‑4 and key arterials, with a growing layer of small cells in commercial zones to support peak-hour capacity.
• Backhaul and fiber support
  • Robust fiber backhaul along major corridors (I‑4/SR‑417) supports 5G capacity; extensive cable and telco fiber presence in business parks (e.g., Lake Mary/Heathrow, Altamonte Springs) facilitates rapid site upgrades and enterprise mobility.
• Public safety and reliability
  • Countywide support for advanced E911 and FirstNet-capable coverage; emergency corridors and hospitals have strong LTE/5G signal layering for redundancy.

How Seminole County differs from Florida overall

• Higher smartphone ownership, especially among seniors (65+), narrowing the digital divide relative to the statewide senior population.
• Lower share of mobile-only internet households (~10% vs. Florida ~15–16%), reflecting higher household income and better fixed broadband availability in suburban neighborhoods.
• Faster 5G device uptake and usage, driven by newer device mix and strong mid-band 5G build along dense commuter corridors.
• Lower prepaid share and higher family-plan penetration than statewide averages, aligned with income and insurance penetration patterns.
• Coverage is more uniformly strong across residential and employment centers than in many rural Florida counties; coverage gaps are mainly limited to protected natural areas rather than inhabited zones.
• Daytime mobile traffic peaks align with office parks, logistics, and education hubs rather than tourism-heavy patterns seen in coastal or theme-park counties.

Key takeaways

• Approximately 4 in 5 residents use a smartphone, and roughly two-thirds of those smartphones are 5G-capable.
• Seniors in Seminole are markedly more connected by smartphone than seniors statewide.
• Only about 1 in 10 households rely solely on cellular data for home internet, well below Florida’s rate, due to strong fixed broadband and fiber backhaul that also bolsters mobile performance.
• The county’s suburban density and commuter corridors underpin robust 5G coverage and sustained capacity growth, yielding better-than-statewide mobile experience in everyday residential and work settings.
