The South Korean company Samsung Electronics announced that, together with the Russian mobile operator MegaFon, it recorded record data transfer rates on the Galaxy Note9 smartphone in the LTE network. The model was tested in an LTE Cat 18 network with 4 MIMO4x4 antennas turned on and 256QAM quadrature modulation. Data transfer rates during testing reached 1.059 Gbps on the current commercial mobile network.
This speed was achieved during joint tests by Samsung and MegaFon technicians. The data was downloaded from the server of the mobile operator. The speed measurement was carried out by a professional software-measuring complex on a Samsung Galaxy Note9 smartphone.
Achievement of such speeds, as noted in the company, was made possible by the presence of the Samsung Galaxy Note9 chipset Exynos 9810, equipped with an LTE cat.18 modem, which allows you to reach download speeds of 1.2 Gbps and 200 Mbps at download. The LTE modem, developed in partnership with Anritsu, offers a 20% increase in performance over the previous 1Gbps cat.16 modem. To maximize the transfer rate, the smartphone uses 4 × 4 MIMO (Multiple-Input, Multiple-Output MIMO) technology and 256-QAM quadrature amplitude modulation.
These speed capabilities allow users to watch live streaming UHD and VR video.
