What exactly is 4G/LTE and how does the technology work?
While the terms 4G and LTE are often used together, I think of them as separate terms and will address them individually. 4G is somewhat vague, but it refers to fourth generation wireless data speeds faster than 3G, which in turn is faster than 2G. Those terms are also somewhat vague, but I think of 1G data as slow dial up, initially 300 bps, eventually upgraded to 600, 1200, 2400, 4800, 9600, on up to maybe 14,400 bps. 2G data was initially in the 14,400 to 56k range and is now typically around 128 Kbps to 256 Kbps. 3G is roughly 1 to 1.5 Mbps and possibly as high as 3 or 4 Mbps. 4G would be anything faster than that, typically 4.7 Mbps on up.
