5G will cost you a bundle

What we need to do is remove all these limits on the amount of data we transfer. If they really want us to use wireless for the home and on the go, they really need to remake the entire pricing plan, as it should have the same service as my landline fiber (unlimited Transfer).

Except the article fails to say that upcoming LTE Advanced service is "true" 4G, not 5G. 4G has multiple requirements and are only satisfied by LTE Advanced and WiMAX 2. Both were ratified in 2011 by ITU-R in the IMT-Advanced specification. The major sticking point is true 4G devices and networks must support up to 100mbit/sec for mobile devices, and up to 1gbit/sec for stationary or low motion devices. In other words, there have been no real 4G (as in, LTE Advanced) deployments worldwide (very few at the end of 2013, most of them in 2014, all of them with extremely limited scope), and none at all in the US. What they are now calling our existing LTE and WiMAX networks is "3.9G". A major feature being introduced by LTE Advanced is complex MIMO, where not only can a device MIMO to a single base transceiver station (one or more of these are on a cell phone tower), it can also communicate with multiple ones belonging to the same network in disjunct physical locations (ie, you could be in a middle triangle of them, and connect to all three if they were configured correctly), and also be able to MIMO with a heterogeneous cluster (as in, a nearby tower and a next generation femtocell sitting on your desk). Most phones will only support 2x2 or 3x3, which is enough to support smooth hand off as you pass by towers. Up to 12x12 is supported, I believe. Other major features are allowing much wider channels, better forward error correction, higher coding complexity (128QAM), and requiring support of cross-band MIMO support Nexus 6 and HTC One M9 (both 2x2, 300mbps downlink maximum) and Galaxy S6 (3x3, 450mbps downlink maximum) support LTE-A, and upcoming LTE-A capable home access points may support up to 8x8 and/or wider channels. A test by DoCoMo managed to get 5gbit/sec with a non-stationary 12x12 100mhz channel test rig. Heterogeneous MIMO seems to be required for Google-Fi, which explains why Nexus 6 can do it but not Nexus 5, although that is just an educated guess.
