Familiarizing Cellular Frequency Bands in Wireless Connectivity

LTE, or Long-Term Evolution is designed to function across a range of frequency bands. Different cellular network operators hold licenses to operate in specific frequency bands and the main band for LTE in your area will depend on the service provider. LTE works on E-UTRA operating bands ranging from 450 MHz up to 3.8GHz.

Cellular IoT is a technology involved in IoT connectivity allowing physical objects to connect to the internet using the same infrastructure as cellular mobile devices. On the other hand, Mobile IoT refers to connecting specific IoT devices with standardized 3GPP low power wide area networks using licensed spectrum. LPWA networks are specially designed for IoT applications that demand low data rates and elongated battery lifespan.

5G frequency bands or the 5G Spectrum utilizes the unused frequency bands in the spectrum. It is divided into 3 sections: Low-band (less than 1 GHz) , Mid-band (1 GHz to 6 GHz),and High band(24 GHz and above). The Frequency Range 1 (FR1) covers sub-6 GHz frequencies, ranging from 410 MHz up to 7125 MHz. Frequency Range 2 (FR2) encompasses millimeter wave (mmWave) frequencies, which range from 24.25 GHz to 71.0 GHz.
