1G frequency

The 2.4GHz band provides coverage at a longer range, but can only transmit data at slower speeds. In contrast, the 5GHz band provides less coverage but transmits data at faster speeds .

Frequency bands of 2G and 3G like 900 MHz and 2100 MHz can also use 4G if more subscribers move from either 2G or 3G to 4G. Recently, Indian telcos are awarded spectrums for 5G technology in both 3.5GHz (n78) and 700MHz (n28) bands.
