[AusNOG] wifi phone calls

[Scott Howard]

Mobile networks have ranges measured in up to (10's of) kilometres.  Wifi
networks have ranges measured in hundreds of metres - presuming these's
nothing too solid to block them.

Providers like Republic Wifi work well simply because the majority of the
time most people are around good wifi signals, but they still need to fill
the holes of coverage - which basically starts the moment you walk out of
the front door.  I have multiple friends that use Republic and couldn't be
happier - they generally say that the quality isn't quite as good as
standard mobile, but for the price they are happy.  (FreedomPop is a
different story, and not a company I'd recommend going near)

However as far as "VOIP" for mobile call, that's happening.  In the US,
Verizon has been doing Voice-over-LTE (VoLTE) for some time, and others
will likely follow.  For Verizon this is a big win as it allows devices on
their CDMA network to handle "voice" and data simultaneously (as it's all
data) - something they haven't been able to do before now.  The LTE spec
fully supports voice-over-data, and it's expected all carriers will move to
it eventually.
