Low-Band
In the context of cellular phones and networks, low-band radio frequencies are those that are below 2.4 GHz. Low-band frequencies can provide excellent coverage, but are not ideal for fast data speeds.
Low-band includes most frequency bands in use for cellular networks before 2019. Only in 2019 – 2022 did US cellular networks start adding higher frequencies in mid-band and high-band (AKA mmWave) radio frequencies, necessitating the new term low-band to distinguish frequency bands with very different coverage and data speed characteristics.
