3r3184. 3r3197. The 5G NR SA macro network segment model in Tokyo included 20 new 5G NR base stations, which were located on the same sites as the existing LTE cells. The 5G NR network model in Tokyo operated in the 100 MHz band at 3.5 GHz and the Gigabit LTE TDD core network in three LTE spectrum bands (3 × 20 MHz) (in Figure 1). The distribution between base stations and devices was modeled on the basis of high-resolution 3D maps of Tokyo, taking into account possible losses during signal propagation, shading, diffraction, losses during passage through buildings, interference, etc. 3r3184. 3r3197. 3r3184. 3r3197. In addition, the simulation included the use of various radio technologies, including Massive MIMO for 5G NR with 256 antenna elements and 4x4 MIMO for LTE TDD networks. 3r3184. 3r3197. 3r3184. 3r3197. The simulation used several types of traffic that mimic the use of devices in real conditions, namely, browsing, file downloads and streaming video playback. In addition, the simulation was carried out for different mixtures (mix) of end devices with different RF capabilities (smartphones of different LTE categories). 3r3184. 3r3197. 3r3184. 3r3197.

The simulation also made it possible to compare how devices in the network transmit data under different signal quality conditions - in 10th (weak signal /work “at the cell edge”), 50th (average signal quality) and 90th percentiles (ideal conditions) . 3r3184. 3r3197. 3r3184. 3r3197. 3r3172. The summary is as follows (see Figure 3): 3r3173. 3r3184. 3r3197. 3r3184. 3r3197. - more than threefold increase in download speed during web surfing: 102 Mbps for the median category of users of 4G LTE networks versus 333 Mbps in 5G NR networks; 3r3184. 3r3197. 3r3184. 3r3197. - approximately a threefold decrease in response time was observed: the median delay in loading decreased from 48 to 14 ms; 3r3184. 3r3197. 3r3184. 3r3197. - approximately fourfold increase in the speed of downloading files in conditions of a weak signal is visible: 131 Mbit /s for 90% of users in the 5G network versus 32 Mbit /s for users in the LTE network; 3r3184. 3r3197. 3r3184. 3r3197. - For users, in the 10th percentile, the quality of streaming video has increased from 480p at 30 fps from 8-bit color rendering (LTE) to 8K at 120 fps from 10-bit color and above (5G). 3r3184. 3r3197. 3r3184. 3r3197. 
In Figure ? in particular, one can see that: [/b] 3r3173. 3r3184. 3r3197. 3r3184. 3r3197. - there is a significant increase in performance when using 5G NR networks, for example, a speed increase to a gigabit level, a decrease in latency, a stable quality of communication and an increase in network capacity; 3r3184. 3r3197. 3r3184. 3r3197. - The importance of Gigabit LTE networks is great for providing high-speed and stable communication for users who leave the 5G NR coverage area. 3r3184. 3r3197. 3r3184. 3r3197. 3r3118. 3r3184. 3r3197. 3r3172.

Uplink modeling (uplink) on 5G NR networks up to 6 GHz in Tokyo
3r3184. 3r3197. Achievable data rates using 5G networks are often the subject of active discussion. And almost always we are talking about the speed in the descending channel from the network and what new opportunities this can give, but very little is said about the speed in the uplink (uplink). But the last parameter is no less important, because application developers need to understand what speed in the uplink should be expected from the networks of the new generation before they start developing or updating their products. 3r3184. 3r3197. 3r3184. 3r3197. That is why we were the first in the industry to add the ability to announce detailed modeling of data upload speeds as part of our platform for testing the capabilities of 5G NR networks and user experience of interacting with them. This platform is designed so as to provide quantitative data on the expected real-world network performance in data upload and user experience when working with multi-mode 5G NR and Gigabit LTE TDD devices operating in 4G /5G NR autonomous architecture networks. 3r3184. 3r3197. 3r3184. 3r3197. As can be seen in Figure ? the tests showed an almost threefold increase in the speed of data unloading during the transition using a mixture of various devices from LTE networks to 5G NR networks. 3r3184. 3r3197. 3r3184. 3r3197. 3r3143. 3r3184. 3r3197. 3r3172.

Figure 6 shows an example of a 5G NR device that implements a traffic model that corresponds to loading into the cloud the PowerPoint file. The maximum upload speed in this usage scenario reached 78 Mbps and it took less than 30 seconds to transfer the file. The figure also shows key indicators, including signal quality, spectral efficiency, MIMO rank, and spectrum frequencies. 3r3184. 3r3197. 3r3184. 3r3197.

3r3184. 3r3197. Modeling the capabilities of 5G networks and user experience of interaction with them demonstrated the potential of 5G technologies, its performance and the operation of 5G networks and Gigabit LTE TDD in standalone mode in real conditions. The results also confirmed a significant increase in the speed of loading and unloading data, which allows to achieve 5G NR, and the readiness of these networks for completely new use cases and the implementation of new services. 3r3184. 3r3197. 3r3184. 3r3197. In addition to this simulation (and other similar ones for other cities of the world), Qualcomm conducted large-scale field tests during the year to test the Qualcomm Snapdragon X50 5G modem. This was done in conjunction with major OEMs, infrastructure providers and mobile operators. And this is another step leading to the appearance on the market of the first wave of consumer devices with 5G support, which is expected in the first half of 2019. 3r3193. 3r3197. 3r3197. 3r3197. 3r3190. ! function (e) {function t (t, n) {if (!
