vivo Y21a 3G – Knowing More
Understanding LTE:
Long-Term Evolution (LTE) is a standard for wireless broadband connections used for mobile devices and data terminals. Its frequencies as following:
3G networks: 900 MHz and 2100 MHz (band 1 and 39).
4G networks: 800 MHz (band 20), 1800 MHz and 2600 MHz (band 7 and 38).
5G networks: 700 MHz (band 28) and 3500 MHz (band 78).
Note: LTE Option in mobiles settings generally refers to 4G networks.
Understanding MHz:
MHz (Megahertz) is a unit of frequency equal to one million cycles per second. It is used to measure the transmission speed of electronic devices, including handheld phone communications.
Understanding Band:
The band is an interval in the frequency domain, defined by a lower and upper values of transmission capacity over network communication systems. However, broadly we are using bandwidth word to refer to the capacity of a network.
