4G LTE Frequency Bands
A curated reference drawn from 3GPP TS 36.101 v15 and the RFWEL knowledge base to help engineers align infrastructure, antennas, and devices with carrier-certified spectrum across the globe.
- FDD BANDS: 13 key profiles
- TDD BANDS: 8 highlighted

North American deployments rely heavily on the 600–2600 MHz range to balance deep indoor penetration with capacity and carrier aggregation options. The table below consolidates the spectrum slices most frequently requested by our indoor coverage clients, together with the operators that certify CPE, routers, and IoT gateways for those bands.
- Reference data sourced from the authoritative RFWEL article "4G LTE Frequency Bands" with supplemental notes from the WDI device database.
- Operators noted below link to certification catalogs in the original article, ensuring multi-carrier designs stay compliant.
- Popular antenna tags map to curated product groupings for rapid system design.
FDD (Frequency Division Duplex)
Spectrum blocks that pair uplink and downlink channels—ideal for macro + indoor DAS builds requiring predictable separation between transmit and receive paths.
