Is it possible to have mobile Internet connection faster than the fiber link? Our 4G LTE network with no problem achieve better results than the copper DSL lines. It turns out that soon we will use the so-called 4.5G network, which will allow us to download data transfers up to 1 Gbps. Does it sound unbelievable? Mobile operators are already testing such solutions, and manufacturers of smartphones keep their pace with them. Motorola recently organized a joint show of strength with Sprint operator from United States.

Overseas mobile operators have already arranged a race to 5G technology. The winner will be the one who first will launch a new generation of base stations. However, from time to time mobile carriers organize demonstrations in order to convince their customers about the technological dominance. At the end of last year, the US branch of T-Mobile proudly showed how without any problem reaches a top speed close to 1 Gbps. While, ZTE has decided to show the world the prototype of their ZTE Gigabit Phone during the MWC 2017. This time, Motorola and Sprint join the group of 4.5G mobile Internet precursors.

Motorola and Sprint organized a demonstration during NBA game in New Orleans

Mobile operators like sporting events, during which boast reliable operation of their networks. I must admit the courage, because the Motorola smartphone was using the commercial operator’s network during the presentation. This means that it was downloading data through the same base stations, which were used by the gathered fans. I do not know if you remember recording presenting in action ZTE Gigabit Phone. The prototype smartphone was connected to the base station emulator via RF cables. While the mysterious Motorola mobile with Snapdragon 835 chipset uses only the built-in antennas.

Practical rate varied between 700 and 900 Mbps

Sometimes the speed fell to about 600 Mbps, but still it was a sensational result. Fluctuations was caused by activity of other users. Used smartphone from Motorola was well camouflaged, so we do not know what kind of model it was. I wonder if it is this year flagship Moto Z. You probably wonder how Sprint and Motorola were able to get so high speed. First, the operator use the radio channel in the 2.5 GHz band with a total width of 60 MHz. While the mysterious smartphone supports MIMO 4×4 and 256 QAM modulation, so it is so-called category 16 device. Interestingly, Sprint does not intend to rest on laurels. This operator is very interested in Massive MIMO solution, which is able to increase the capacity of a single LTE cell to about 3-6 Gbps. Sounds promising, I am curious how it will work in the practice.
