Hi Rob,
Looking at the Australian example, we can analyse the industry using the
ACMA database. There are about 42,733 mobile sites (devices with an ACMA
licence for Spectrum or PTS) for Optus, Telstra and Vodafone. The same
database shows only 11,584 point to point microwave licences for the
It's a nice idea, and I'm sure more efficient in Opex and over a long
period of time with the benefits of upgrades like you say, but the Capex of
deploying all that fibre would be huge, especially as cells get more
abundant. That's why everyone really likes packets :)

Dark fibre to cell sites opens up more possibilities than just bandwidth.
Potentially the raw analogue waves from antennas can be re-modulated onto
DWDM wavelengths and then digitally [de]modulated in a datacenter.
This makes the whole process more efficient, reducing power and weight
It is certainly my hope more will also deploy bufferbloat fighting
solutions at various points.
Typical cell bufferbloat is in the 1.6 second range, and would be
worse if various protocols didn't just time out

Hi All,
I thought I'd follow my comments up with information on a new cell site
backhaul product launched in NZ this week.
https://sp.chorus.co.nz/product-update/launching-voluntary-mobile-access-service-mobile-sites
1 Gbps fibre tail, upgradable in the future.
My best guess is that future

It's complicated
Ignoring channel aggregation (CA), the maximum amount of spectrum available
to an LTE endpoint is 20Mhz, which is shared with everyone in the same
sector. The amount of spectrum might be as small as 1.5Mhz
If you have say an iPhone X with 2x2 MIMO, and can stand close enough to
"That tends to be more a regional issue when backhauled by microwave"
I guess also some areas that have only Telstra backhaul (Think anything
north of Geraldton in WA for example) would only buy minimal amounts of
backhaul from Telstra to a capital city.

I do a 'little' bit of radio work so I am in no way an expert.
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
+1 needed for clarification also.
Philippines carriers are a mess.
Just to add to the mix, the provider I use has 10+ APN's, and on any given
day, 1 or 2 of the APN's will be consistently faster than the other 8.
So Backhaul, Spectrum, APN are the factors where I cannot figure the
slowness.
