I do a 'little' bit of radio work so I am in no way an expert.<br>

From my understanding it can be a mixture of both. Metro areas
shouldn't really have a problem on backhaul as busy towers would
have 10, 40, or even 100gbit circuits to the base of the tower,
that tends to be more a regional issue when backhauled by
microwave.<br>
<br>
Spectrum - to simplify things think of a single chain Wireless
802.11G, old school 54mbps Wifi in the 2.4ghz 20mhz channel (or
10mhz, i forget what G was) - 54Mbps is the total airtime so to
speak, that means 1 user using it can get up to 54mbps, add 10
users, and they all try using it together, they are not all going
to get 54mbps at the same time. They are essentially sharing that
pool of bandwidth between them.<br>
<br>
There are of course many other factors, TDMA timings, spectrum
sharing, MIMO etc, but at a simple overview, more people putting
more demand in the air = more noise for the radios to fit in a
limited spectrum.<br>
<br>
As said there is a lot more to it then that but should get the
discussion started.<br>

Each APN is likely being broadcast by a different radio/cell on the
tower (or even potentially different towers), if certain cells/APN's
are super busy, then you are likely getting onto the less busy ones
when you get better results.<br>

<div>I understand that this isn't directly related to shifting

feel like my understanding of things is wrong - if somebody
has a few minutes for a diversion to their day - I'd love
some clarity.<br>

<div>If a mobile carrier was to remove data caps, there would
obviously be increased demand on the network. One of the
arguments against removing data caps is that there is "not
enough spectrum" available - and this there would be a
massive speed impact for all users of the cell/tower.<br>

<div>My understanding was that the tower slowdowns were
typically related to a lack of backhaul - but the argument I
