Early cellular networks, including 1G, operated at a frequency of 850 MHz and 1900 MHz . Then, 2G and 3G networks operated at additional frequency bands and spectrum around 2100 MHz, and 4G LTE technology operated at additional frequency bands and spectrum around 600 MHz, 700 MHz, 1.7/2.1 GHz, 2.3 GHz, and 2.5 GHz.
Read moreWhat is the frequency of 5G?
High-band 5G uses frequencies of 24–47 GHz , near the bottom of the millimeter wave band, although higher frequencies may be used in the future. It often achieves download speeds in the gigabit-per-second (Gbit/s) range, comparable to cable internet.

3G typically operates in separate frequencies than 2G and 2.5G uses , thus allowing mobile phones to switch from one to the other when capable. Summary: 2.5G implements packet switching along with the circuit switching in 2G. 2.5G has much faster data rates than 2G.

The main difference between 4G LTE and 5G NR is that the maximum bandwidth in 5G is higher than 4G LTE networks. As a result, 5G NR networks can accommodate higher data rates than 4G LTE. … TermStands forLaunch Year1GFirst Generation19792GSecond Generation19913GThird Generation20014GFourth Generation2009What do the terms 1G, 2G, 3G, 4G and 5G really mean? – Commsbrief commsbrief.com › what-do-the-terms-1g-2g-3g-4g-and-5g-really-mean
Read moreWhat are the advantages of 2G over 1G?
Advantages of 2G over 1G It allows voice signals to be digitized and compressed . So, they are more efficient on frequency spectrum than 1G. They introduced data services for mobile in form of SMS text messaging. Data and voice signals are digitally encrypted.
Read moreWhat is the key difference between 2G and 3G?
The primary difference between 2G and 3G networks for mobile subscribers is that they get to enjoy faster Internet browsing and data downloading on 3G . On average, the speed of data transmission on a 2G network is only 170Kbps, while in 3G networks the downloading speed can go up to 42Mbps (or 43,000 Kbps).
