LTE 450 is gaining attention now because of the set of attributes it offers. The 450MHz band is able to support CAT-M (LTE-M) and narrowband-IoT (NB-IoT) technologies and the physics of the band are well-suited for large area coverage, which has enabled cellular providers to offer blanket coverage cost effectively. Comprehensive coverage demands lower power consumption by IoT devices so they can remain connected and the deeper penetration means devices can easily connect to a network without energy draining repeated attempts. With national networks already rolled out in some countries, the arrival of CAT-M and NB-IoT have reinvigorated uptake and usage of the 450MHz band.
