The same way True 4G had a real definition based on IMT-Advanced, the ITU released in February 2017 the draft of IMT-2020 describing the minimum requirements related to technical performance for IMT-2020 radio interface(s), which sets the goals for 5G.
3GPP has unveiled the logo and name which will be used for 5G networks, which will be called 5G (unlike 4G which official name has been LTE). This designation and logo are meant to be used from 3GPP Release 15 and onwards and intend to show some kind of continuity between LTE and 5G.
Hyperloop Transportation Technologies (HTT), one of the American start-up which develops a concept of super fast train moving on electromagnetic suspension at 1,200 km/h has recently signed an MoU with the region of Occitania in France to set-up its European R&D center. This made me wonder how it will be possible to communicate from an Hyperloop train with our smartphone.
In a previous post I presented how to calculate the maximum throughput of LTE, and this was focusing on LTE FDD (Frequency Division Duplex), where an equal bandwidth of spectrum is allocated for both the Downlink and the Uplink. As a reader asked, in this post we do the same for LTE TDD (Time Division Duplex) a.k.a TD-LTE.
Snapdragon just announced the X16 LTE Modem that can achieve 1 Gbps throughput thanks to higher order modulation (256 QAM), 4×4 MIMO and 4x Carrier Aggregation of 20 MHz. But how can we calculate the maximum theorical peak LTE throughput depending on those parameters?
There is a race between equipment manufacturers, chipset manufacturers, carriers and standardization bodies to take the lead on defining what 5G will actually be. One of the hot topics is the choice of the most appropriate waveform and mutliple access method to meet the requirements of 5G.
