I thought bytes and megabytes were used in modern terminology, not bits and megabits.
However in this article and others, it uses megabits a lot. Is this a trend? Or was my first line wrong?

If you have 4G and want to download a 100M file, how long would it take (don't need superexact figures here)?
Also, MB is megabytes but Mb is megabits. What if you just see 100M?
Just to be clear, the US has bastardized the marketing aspect of "4G".
AT&T has called "4G" their HSDPA/HSUPA network which technically is 3.5G in terms of technical speed ( in a lab).
Now we have 4G LTE. Which isnt exactly LTE either but is a true 4G.
LTE the standard is actually faster on uplink and downlink speeds than what exists right now. What we have in LTE for the US kind of is like diet LTE. Not true LTE based on the specification. I am actually surprised they got away with marketing it this way.
In the lab recently 5G speeds have been clocked notably by Samsung, but Qualcomm and other chip makers have been working on that for a while.
You wont get exact figures for a 100MB file over LTE, but generally speaking a file that size should take about 20 seconds in the real world. There are various factors involved which could decrease or increase that time, but as I have seen professionally in major metros, this is roughly an average.
Cellular networks are note really developed to deliver content that size in a steady stream. For example, you might see the first 20MB download in 5 seconds and the rest start throttling down in speed over time.

In digital world this > 1 is a bit. A megabit would be one million of those transferred at once, essentially. Eight bits = 1 byte; a byte looks like this: 01010101. A megabyte would be 1 million of those transferred at once, essentially.

Not surprised, they get away with charging you for a pound of bacon when its actually less.

Yeah, I am actually surprised they were able to market it this way. The standards and definitions they have to adhere are usually pretty strict.
It was short lived with AT&T anyway. There were some devices they had labeled as 4G (but not LTE) when Verizon was first to launch their LTE network to the masses. 4G just sounded more impressive and while in some ways, technically true that it was 4G, was a bit grey area.
Then T-Mo hopped on the bandwagon. Basically all they did was update their existing 3G network, which is why TMo broadcasts as 4G. 3G isnt even an option with TMo, even though that is what users are technically sitting on. lol

They can get away with it because the ITU (the folks who control 4g standards) said they can call LTE-FDD/TDD, WIMAX, HSDPA, etc 4G.

Thanks NJBest! You clarified my point. even the ITU way back when admitted its not true 4g by their own standards.
We were discussing this stuff years ago and even then we were all confused by their conventions.

ITU revised their statement about what can be called 4G. The issue is that 4G is fairly ambiguous. LTE, Wimax, etc. is 4th generation. As such, it should be referred to as 4th generation.
The 3rd generation Prius never hit it's originally spec'd mileage. It doesn't make the 3rd generation Prius a 2.5 generation prius. It just means that the 3rd generation Prius missed the mark.
Similarly, the 4th generation cell radios didn't meet the spec. But they are still 4th generation cell radios. That is ITU's perspective on the situation.

Not so sure about that first paragraph.
LTE, Wimax are certainly 4G, I dont think that was the issue.
HSDPA/HUSPA via WCDMA/UMTS is most definitely not, which is simply existing 3G infrastructure on steroids...hence the fake 4G I was referring to and why the ITU retracted. Native CDMA networks never had this issue to begin with. EVDO data went straight to an LTE overlay.
In other words, EDGE was 2.5G, but was always considered 2G...never 3G. They did develop an EDGE+ but that never truly materialized.
Not sure what you mean by 4th Gen cell radios not meeting spec.
