4G vs 5G Speed — How Much Faster Is 5G Really?
5G is theoretically up to 100x faster than 4G LTE, but real-world results are far more nuanced. The 5G you experience depends heavily on which “flavor” of 5G you’re connected to — low-band, mid-band, or mmWave — each delivering very different speeds.

5G Bands — The Three Different Experiences
| 5G Type | Frequency | Download Speed | Coverage | Latency |
|---|---|---|---|---|
| Low-band 5G (Sub-1 GHz) | 600–900 MHz | 30–100 Mbps | Excellent, rural | 20–40ms |
| Mid-band 5G (Sub-6 GHz) | 2.5–4.7 GHz | 100–500 Mbps | Good, suburban | 15–30ms |
| mmWave 5G | 24–47 GHz | 1–4 Gbps | Very limited, dense urban | 5–15ms |
| 4G LTE (comparison) | 700 MHz–2.1 GHz | 20–150 Mbps | Excellent, everywhere | 30–60ms |
The Truth About Low-Band 5G — Barely Faster Than 4G
Low-band 5G (the type most people see on their phone icon) provides marginal improvement over 4G LTE — often only 10–30% faster. Many carriers launched 5G on low-band spectrum to maximize coverage map claims. When you see “5G” on your phone in a rural area, you may be getting 50 Mbps — similar to good 4G LTE. This is why many people feel 5G hasn’t lived up to its promise. The truly impressive speeds require mid-band or mmWave 5G deployment.
Mid-Band 5G — The Sweet Spot
Mid-band 5G (2.5–4.7 GHz, including T-Mobile’s 2.5 GHz and AT&T’s C-band) delivers the combination of coverage and speed that 5G was designed to offer. Real-world mid-band 5G speeds of 200–400 Mbps with 20–30ms latency represent a genuine and substantial upgrade over 4G. This is the 5G powering 5G home internet products and delivering transformative mobile broadband. Test your mobile data speed with our mobile speed test guide.

Frequently Asked Questions
Is 5G faster than home WiFi?
Mmwave 5G can exceed home WiFi speeds but is extremely limited in availability. Mid-band 5G at 200–400 Mbps matches or exceeds most cable internet plans and many fiber entry-level plans. Low-band 5G at 30–80 Mbps is slower than most modern home internet plans. For most people in suburban areas, mid-band 5G is comparable to a fast cable connection — genuinely fast enough for mobile use.
Does 5G have lower latency than 4G?
Yes — 5G’s architecture allows lower latency than 4G LTE. Real-world 5G latency ranges from 10–40ms versus 4G’s 30–60ms. The biggest latency improvements come with mmWave 5G (5–15ms) in dense urban deployments. For 5G home internet and mobile use, expect 20–30ms on mid-band 5G versus 35–50ms on LTE.
Should I upgrade to a 5G phone for better speeds?
If you’re in a mid-band 5G coverage area, yes — the speed improvement over LTE is substantial (200–400 Mbps vs 30–100 Mbps). If you’re in a low-band 5G area, the upgrade provides minimal speed benefit. Check your carrier’s coverage map for mid-band 5G (often called “5G+” or “Ultra Capacity 5G”) at your typical locations before deciding whether the upgrade is worthwhile.
