However, for lower latency (not speed) is what I would assume would make a big difference especially when using Maps etc.
See what I read and why I thought LTE may be quicker:
https://www.quora.com/How-4G-has-less-latency-than-3g
1) LTE typically has higher data rate. All things being equal, faster data = lower latency
2) Things are not equal, 3G is essentially a circuit switched architecture. HSPA adds an always on packet switched layer, buts:
- CS was desifgned for voice. It is OK to take a few seconds to set up a call (session) because a voice call last minutes. But for data you set up and tear down sessions much more often & faster. But 3G stacks and architecture were never designed to be low latency: that just was not a priority.
So 3G = latency was no big deal
LTE = low latency was a key, priority, design requirtement
- 3G is a hugely complex, kludgy, multi-later architrecture with lots of nodes and lots of parallel strands.
voice, CS data, PS daa, HSPA etc - all interacxting
Node B, RNC, packet core =- all interacting
In contrast, LTE (while very compex) has a"flat architecture" and a much more optimized stack. It is IP, only IP and everything is IP.
