UHF (300–1000 MHz)

🌐 Summary

The 843 MHz allocation is part of the UHF (300–1000 MHz) spectrum. This range is used worldwide for critical applications that keep our communications and infrastructure running smoothly. On this page we highlight how each band is applied in real systems, from regulatory assignments to everyday devices. Our goal is to make spectrum data clear and practical for engineers, regulators, and enthusiasts alike.

Key uses of this band include: 843 MHz: Cellular uplink paired with 869–894 MHz downlink; Mobile, Fixed; GSM/UMTS/LTE/NR uplink; LTE/NR smartphones, legacy GSM/CDMA devices.

Cellular 850 uplink (3GPP Band 5 UL 824–849 MHz; Band 26 extends down to ~814 MHz); legacy AMPS/IS‑95 evolved to LTE.
