LTE Band 24, often referred to as the U.S. L-Band, occupies an unusual section of spectrum. Traditionally allocated for Mobile Satellite Service (MSS), the potential of this band for terrestrial mobile communication became apparent over time. The integration of this band into the LTE spectrum portfolio was more than just a frequency expansion; it aimed to harmonise satellite and terrestrial services.
Located in the 1600 MHz range, the inclusion of this band into the LTE spectrum was viewed as a method to enhance broadband capacity. As it's primarily designed for use in the United States, its implementation has been greatly influenced by the region's regulatory and technical environment.
A significant challenge of the U.S. L-Band is maintaining balance between conventional satellite operations and the emerging terrestrial mobile services. The coexistence with MSS operations implies that any LTE deployment in this area must be conducted with caution, ensuring strong services without infringing on the territory of existing satellite communications.
