End of DSL
If FTTH is not what you provide copper DSL in the developing world would be a joke. In most of those countries the POTS lines barely work. I don't know what level 2G, 3G, 4G or LTE but the cell system is cheaper and more reliable.
Slow DSL is being killed off in the US. I think at&t and Verizon are moving to cell LTE internet service if Uverse or FTTH is not already in place. If it was not for the caps and high cost LTE would be a better deal for speed then old 3 or 6 meg DSL.
