4G LTE & 5G Coverage In Miami
The table below shows the proportion of Miami with coverage from different cellular technologies.| Network | 4G Coverage | 5G Coverage |
|---|---|---|
| AT&T | 98% | 93% |
| T-Mobile | 100% | 100% |
| Verizon | 100% | 98% |
| Dish | 0% | 78% |
Don't be alarmed by Dish's lack of 4G coverage in Miami. Dish has a newly-built network that's 5G-only.
US Cellular And Dish Roaming Coverage
US Cellular does not have native coverage in Miami. However, some US Cellular subscribers may still have coverage in Miami thanks to roaming agreements.
The 78% figure for Dish may understate what subscribers in Miami experience after accounting for roaming agreements.
Millimeter Wave 5G
Parts of Miami have millimeter wave 5G coverage. This novel celluar technology offers extremely fast speeds, but the coverage potential is limited. Millimeter waves aren't well-suited for traveling long distances.
| Network | Millimeter Wave |
|---|---|
| Verizon | ✓ |
| AT&T | ✓ |
| T-Mobile | ✓ |
Millimeter wave coverage in Miami is likely sparse (mostly limited to dense, outdoor areas like popular parks or sports stadiums).
Miami Cell Signal Strength
There are 1,310 map hexes within the census-defined boundaries of Miami. The table below shows the proportion of hexes at various levels of signal strength. Where both 4G and 5G coverage is available, data is drawn from whichever technology offers a stronger signal.
| Network | Strong | Decent | Weak | None |
|---|---|---|---|---|
| AT&T | 28% | 63% | 8% | 1% |
| T-Mobile | 92% | 7% | 1% | 0% |
| Verizon | 48% | 51% | 1% | 0% |
| Dish | 4% | 69% | 6% | 22% |
For most purposes, decent signals are perfectly sufficient. Weak or non-existent signals cause far greater degradation in user experience.
Due to data-reliability concerns, 309 hexes in Miami that fall in bodies water, along rivers, or near shorelines are excluded from the table above.
