Barcelona, ​​Spain, February 25, 2018 - Qualcomm Incorporated (NASCOMQ: QCOM) subsidiary Qualcomm Technologies, Inc. today announced a number of important results from its extensive 5G real-world network simulation experiments over the past few months. Qualcomm Technologies' 5G network capacity simulation experiment provides quantitative insight into the expected real-world performance and user experience of 5G and Gigabit LTE terminals operating in a non-independent (NSA) multi-mode 4G/5G new air interface network, demonstrating the potential of 5G . As the industry is preparing for the launch of the first 5G networks and terminals in the first half of 2019, the results will also provide quantitative support for the significant capacity gain achieved by deploying 5G new air ports on 4G LTE.
Alex Holcman, senior vice president of engineering at Qualcomm Technologies, Inc., said: "Many members of the mobile ecosystem - including cloud platform vendors, application developers and terminal OEMs - are very interested in learning about 5G's new air mobile network and The true performance of the terminal. We conducted this comprehensive study to help the ecosystem prepare for 5G, for example, application developers can begin to plan new experiences and services that can be delivered to users through 5G terminals."
Qualcomm conducted two independent network simulation experiments. The first experiment simulates an NSA 5G new air interface network in Frankfurt, Germany, operating on a 3.5 GHz spectrum with a bandwidth of 100 MHz. The underlying Gigabit LTE network runs across five LTE bands. The second experiment simulates a hypothetical NSA 5G new air interface network in San Francisco, California, operating on a 28 GHz millimeter-wave spectrum with a bandwidth of 800 MHz. The underlying Gigabit LTE network spans four LTE licensed bands and multiple licensed auxiliary accesses. (LAA) band operation. Both of the above network simulation experiments utilize the existing cellular base station locations in Frankfurt and San Francisco to achieve the co-location of the 5G new air interface cellular base station with the existing real LTE base station.
The Frankfurt network simulation experiment shows that for a pure LTE network (using LTE terminals with different functions in the network), the implementation of a 5G new air interface network (multi-mode 5G new air interface terminal and more advanced Gigabit LTE) After the migration of the terminal, the downlink capacity can be increased by up to 5 times. The experiment also achieved up to four times the spectral efficiency averaging on the 3.5 GHz spectrum, providing convincing evidence for the performance gains that massive MIMO technology can bring.
In addition to network capacity enhancements, the network simulation experiment also demonstrated a significant improvement in user experience for 5G new air interface terminals (compared to LTE terminals), including:
Browse download speed increased from 56Mbps for 4G user average to over 490Mbps for 5G user average, achieving nearly 900% gain
The response speed is nearly 7 times, and the browsing download delay average is reduced from 116 milliseconds to 17 milliseconds.
The file download speed of 10% of 5G users is equal to or less than 100Mbps, that is, 90% of 5G users download speeds exceed 100Mbps. Correspondingly, 10% of LTE user file download speed is equal to or less than 8Mbps
The average streaming video quality is increased from 2K/30 FPS/8-bit color (bit-color) of LTE users to 8K/120 FPS/10-bit color and above of 5G users.
On the other hand, the San Francisco network simulation experiment demonstrates for the first time the impact of significant capacity increases on the 800MHz additional millimeter-wave spectrum on the real user experience. Important results include:
The browsing download speed is increased from 71 Mbps for the 4G user average to 1.4 Gbps for the 5G user average within the millimeter wave coverage, achieving a gain of nearly 2000%.
The response speed is nearly 23 times, and the browsing download delay average is reduced from 115 milliseconds to 4.9 milliseconds.
90% of 5G user file download speeds exceed 186Mbps, compared to 10Mbps for LTE, achieving 1826% gain. 5G file download speed average is 442Mbps
The average streaming video quality is increased from 2K/30 FPS/8-bit color of LTE users to 8K/120 FPS/10-bit color of 5G users and above.
The 5G network capacity simulation experiment results further prove the great potential of 5G, and the real performance expected by 5G is much better than the current 4G in many evaluation indicators. Network simulation experiments have also shown that these emerging 5G networks will have sufficient capacity and performance to support a large number of new services and experiences in addition to traditional browsing, downloading and streaming. 18 operators worldwide and 20 leading terminal manufacturers have chosen Qualcomm® X50 5G modems for the first 5G network test and consumer terminals, and the industry is ready to offer these to users in the first half of 2019. Amazing 5G user experience.
About network simulation experiment methodThe 5G network capacity simulation experiment is based on the unique ability of Qualcomm Technologies to accurately model and simulate cellular systems.
The network simulation experiment uses the existing base station location to realize the co-location of the 5G new air interface cellular base station and the existing LTE cellular base station. Approximately 14,000 user terminals with different functions are randomly distributed throughout the network, including approximately 50% of indoor users and 50% of outdoor users. The combination of terminal, terminal functions and the frequency band/bandwidth used by the terminal is based on the expectation of commercial deployment of pure LTE and NSA 5G new air interface networks in 2019. Network simulation experiments show different traffic patterns based on a combination of representative mobile applications including browsing, cloud storage downloads, and adaptive bit rate video streaming.
The network simulation experiments are based on models of physical base stations and their RF functions, including massive MIMO functions with 5G new air ports below 6 GHz using up to 256 antennas, and 5G new air interface millimeter wave beamforming with 256-element antenna panels. Pure LTE traffic is modeled based on base stations with 4 antennas. The propagation between base stations and terminals is based on detailed 3D urban microcells and urban microcellular models, including path loss, occlusion, diffraction, and building penetration losses, leveraging Quantcomm Technologies' extensive OTA testing and channel measurement . To ensure that network simulation experiments can reflect the real mobile environment, this lab also models the base station interference that serves different users simultaneously, including the true consideration of Wi-Fi users in the LTE (LAA) model in the unlicensed spectrum. influences.
From February 26th to March 1st, participants from the Barcelona World Mobile Congress will be able to visit the network simulation demonstration at Qualcomm's booth at Hall 3E10 in Hall 3.
