Telstra are trialling voice over LTE with their "4GX" (700mhz LTE-A) product.

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.

Hi

So I saw this whilst I was reading Slashdot.

This got me thinking, if you took money out of the equation and politics (sic).  Would it be better for use to have a completely wifi wireless network, get rid of the mix of technology and just have devices that do some sort of VOIP.  I am presuming running an IP network is better than a GSM/3g/4g.

How much better would that be ?
