5G operates on a wide range of frequencies, divided into two main bands: FR1 and FR2. FR1, also known as sub-6 GHz, covers frequencies from 410 MHz to 7.125 GHz. This band overlaps with frequencies used by LTE, allowing for the use of existing infrastructure in some cases. FR2, known as the mmWave (millimeter wave) band, ranges from 24.25 GHz to 52.6 GHz, offering higher bandwidth and faster speeds but with reduced coverage and penetration compared to FR1. The specific frequencies used can vary by country and region, depending on regulatory approvals and availability.
