You are correct in the LTE doesn;t refer to a specfic technology and in fact LTE-A (LTE-Advanced) is soon to hit deployment. LTE-A refers to many things as well. That the marketers call 4G is in fact an enhanced 3G. The real 4G will be LTE-A.

@Jack, I often refer to anything that relates to both the Apply phones and tablets as "iThings."

This is an interesting discussion.  These 1G 2G 3G terms are so generalized that they do not exactly convey the kind of enhancement that has happened between them.  (BTW my family doctor while prescribing a diabetic medicine for me wrote Gluconorm 3G instead of writing Gluconorm G3  and the chemist had a hearty laugh reading it saying , my doctor had got it all mixed up with with the internet speed!)

Even the word LTE has me confused about what could be its actual long form - actually the Long Term  Evolution does not convey anything about the underlying technology, network speed or network topology.

For Ethernet speeds we had the terminology starting with 10mpbs then 10/100 and then 100mbps . I am not tracking the current Ethernet speeds but they must have now reached G levels.

So how about naming these mobile communications evolutions as per their speeds like the Ethernet, instead of just naming as first, second, third , fifth generation.

By associating the speed , we can get exact idea how improved it is from the earlier generation.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
