LTE adoption report: Asia has the best performing networks, 20 Mbps connections now commonplace, and the US is falling behind others in speed
The State of LTE — Have we fully entered the 4G age? The answer to that question depends on where on the globe you live.
Context & Ripple Effects
Six months after [[a:827280|OpenSignal's March finding that South Korea had the best LTE coverage while US speeds ranked among the slowest]], this September State of LTE report doubles down on the same geography: Asia holds the top of the table, and 20 Mbps connections have shifted from exceptional to ordinary. The US, by contrast, appears again on the wrong side of the speed ranking.
The report matters because it turns a one-off measurement into a pattern — and later data confirms the pattern held rather than corrected itself.
First-order effects
- Asian operators enter the next capex cycle with crowdsourced proof their networks lead globally, while US carriers face a public benchmark showing them falling behind on speed despite LTE being ubiquitous there.
- For US consumers, '4G' branding no longer maps to experience: 20 Mbps is now commonplace elsewhere, making the domestic gap visible in everyday use.
Second-order effects
- Speed rankings become a competitive weapon between US carriers — OpenSignal's own follow-up work showed T-Mobile taking the fastest-US-network crown with Verizon close behind and AT&T and Sprint lagging — pushing marketing toward measured performance claims.
- Persistent US underperformance pressures carriers to accelerate spectrum deployment and densification spending to avoid ceding the premium-data market.
Third-order effects
- The lag proves structural, not transient: by 2019 OpenSignal had the US at 55th in LTE download speeds, and the 2020 report found US 5G averaging just 1.8x its own 4G speeds, still behind South Korea and Saudi Arabia — each generational transition inherits the previous one's gap.
- Crowdsourced measurement firms like OpenSignal and Ookla become de facto arbiters of network quality, shifting accountability for carrier claims from marketing decks to device-level telemetry.
The trend: Mobile network quality leadership is consolidating in Asia across successive generations, with US carriers repeatedly benchmarked below global peers from LTE through early 5G.
