What's the difference between 3G, 4G, 5G, and LTE proxies?

These 3 proxies are different in simple words.
​
3G proxies – As the name suggests, these are third generation wireless mobile telecommunication technology. But their speed is not that fast and nowadays their usage is almost none.
​
4G proxies – These are used much more compared to 3G. They provide much better reliability. They are widely used for mobile internet and so on.
​
5G proxies – This is the latest technology compared to the two types mentioned above. They are quite reliable for high-bandwidth applications, but compared to 4G they are not used that much because they are a bit expensive.
​
LTE – The full form is Long-Term Evolution. It can be considered as something between 3G and 4G. Most people think it is 4G, but it actually came before 4G. And these proxies perform better than 3G, but they do not always maintain the standards of 4G.
