Daniel,
Thanks for the wealth of information. What kind of speeds are you offering?
How many customers are you putting on one of these boxes? What modems are
you using?
I would honestly perfer something that was hardened for outdoor use. Think
garden style apartments. What is the best for something like that?
Comparing DOCIS 3 to VDSL2, the modems and CMTS appear to be more cost
effective per customer. G.FAST I have not seen pricing on, but I expect it
to be more than VDSL2.
Any reasons not to use EURO DOCSIS in the USA? Looks like it offers more
speeds by using fatter channels. We don't plan on offering TV, but even if
we did couldn't we just start the channels at a higher range, and still use
EURO DOCSIS?
