4G 5G smartphones — Your smartphone is 4G? What does that mean? The “G” stands for generation.
The first generation or 1G were the analog cellphones of 1983. 2G was digital and allowed for texting. 3G allows for internet access and 4G allows for wireless broadband connections.
5G is expected to come out next year and be between 10 and 100 times as fast as 4G.
And LTE? That stands for “long-term evolution.’
As of 2010 there were 5 billion mobile cellular subscriptions in the world. The Earth’s population is about 7 billion.
