GCF (Global Certification Forum) announced on June 6, 2024 that it is adding devices using the 450 MHz frequency band (currently corresponding to the LTE frequency bands B31 and B72) to its certification process.

Manufacturers will be able to obtain GCF certification for LTE devices within the 450 MHz spectrum range, particularly those related to industrial, utility, and critical communication equipment and applications.

Lars Nielsen, CEO of GCF, said, "We are pleased that with the joint efforts of our members and partners, this new certification is the first in the industry and promotes the development of the 450 MHz device and service ecosystem

After years of collaboration between GCF and the 450MHz Alliance, cellular frequency bands within this spectrum range are becoming the preferred choice for many industrial, mission critical, and IoT applications worldwide, including smart meters and smart grids.

Characteristics of 450 MHz frequency:

1. Provide excellent coverage for applications that require low data bandwidth, covering industry, Mission Critical Services (MCS), and utilities.

2. The long-distance transmission capability of 450 MHz frequency is unmatched by higher frequency cellular bands.

3. LTE devices using this frequency band have the ability to transmit and receive signals with high penetration through walls and buildings, thereby improving signal coverage in indoor and underground scenarios.

In addition, GCF certification will be extended to other frequency bands and radio access technologies on the 400 to 450 MHz frequency range, such as LTE Cat-M and 5G NR RedCap.
