The Global Certification Forum (GCF) announced the addition of certification for devices using 450 MHz bands. This certification will ensure compliance with the highest quality and interoperability requirements for devices operating in the 400 to 450 MHz spectrum range, with LTE bands B31 and B72 initially in focus.
Cellular bands in this spectrum range are increasingly preferred for various industrial, mission-critical, and IoT applications globally, including smart meters and smart grids. The 450 MHz ecosystem encompasses device and technology vendors, network operator mission-critical services (MCS) operators, utilities, and industrial companies.
The new certification is the result of a multi-year collaboration between GCF and the 450MHz Alliance, the industry organization advocating for the global use of the 450 MHz spectrum and representing stakeholders in the 450 MHz ecosystem.
Frequencies in the 450 MHz spectrum range offer extensive coverage for applications requiring low data bandwidth in industries, MCS, and utilities. While higher-frequency cellular bands can deliver higher data rates, they lack the long-range capabilities of the lower 450 MHz frequencies. Operating at lower frequencies also enhances penetration through walls and into buildings, thereby improving indoor and underground coverage.
The certification scope will be expanded to include additional bands and radio access technologies on the 400 to 450 MHz bands, such as LTE Cat-M and 5G NR-Light (also known as reduced capability, or RedCap).
