I'm looking at moving to Hyogo prefecture, around the Nishinomiya area and the buildings I'm considering have both AU and NTT infrastructure installed.
From doing postal code searches it seems they have both AU Type G and Flets Hikari Next, so I'm wondering which one is technically a better/more consistent solution. I know this is dependent on a lot of location factors like building age, number of subscribers, ISP, the phase of the moon, etc. but the AU vs. NTT infrastructure is technically different in a number of ways that I'm curious to understand.
Here's what I've gathered from a bit of research and diving into previous reddit posts around this, but I'm not sure to the extent this is all true:
NTT Flets Hikari Next
- Maximum of 1 Gbps up & down, but realistically probably won't get that much?
- Seems to be true FTTH/fibre to the unit?
- Requires IPv6 IPoE for maximum speeds, method/technology depends on the provider (of which the wiki has this laid out well)
- NTT infrastructure is generally older and more congested because more people use it, which may cause slowdown
AU Mansion Type G
- Maximum of 664 Mbps up & 100 Mbps down – same as above, probably won't reach the maximums for either but I don't particularly care for upload speed
- VDSL supported by "g.fast" technology powered by Nokia, which allows higher download speeds compared to normal VDSL, but still shared infrastructure so it might be affected by other users in the building
- Doesn't seem to need IPoE
- AU/KDDI infrastructure seems to not be "oversubscribed" which means more consistent speeds?
It could be the case that optical fibre is just straight up better than VDSL (even with g.fast) which is fine, but if anyone has any experience with these or any technical knowledge on which is a better (as in more consistency – speeds, low ping/jitter, general uptime) solution I'd love to learn. Thanks!
