🌐 Summary
The 1753 MHz allocation is part of the L-Band IMT/AWS 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: 1753 MHz is part of the terrestrial mobile FDD uplink band used for LTE and 5G NR transmissions from user equipment to base stations. It is paired with downlink spectrum above 1800 MHz (region‑specific) and subject to national licensing and coordination frameworks. This sub‑range aligns with 3GPP Band 4 (AWS‑1) and Band 66 in many regions, and also falls within the wider international Band 3 uplink..
