All marketing hype to the contrary, if the first commercialized fifth generation (5G) “mobile” networks emerge by 2020, it is almost certain that 5G will be built on a 4G foundation and other current technologies, including better antennas using MIMO, channel bonding, small cell architectures and use of both Wi-Fi and Long Term Evolution air interfaces.
There is precious little time to do anything else. Consider, for example, KT Corp.’s plans to commercialize the world’s fastest mobile network, called “Giga LTE,” that apparently provides that speed by bonding both Wi-Fi and LTE capacity, as the Korea Herald reports.
Giga LTE also provides upload speeds 10 times faster than LTE-A, and relies on use of Samsung smartphones including the Samsung Galaxy S6 and S6 Edge.
But Giga LTE also shows how the future 5G platform almost has to extend present technology trends.
