Barcelona, Spain, February 25, 2018 – Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated (NASDAQ: QCOM), recently shared key findings from its comprehensive 5G real-world network simulation experiments conducted over the past few months. These simulations provided valuable insights into how 5G and Gigabit LTE devices will perform in a non-standalone (NSA) multi-mode 4G/5G network environment. The results highlighted the immense potential of 5G technology and supported the industry's preparations for the first wave of 5G networks and devices launching in the first half of 2019.
Alex Holcman, Senior Vice President of Engineering at Qualcomm Technologies, said, “The mobile ecosystem—ranging from cloud providers to app developers and device manufacturers—is eager to understand the true performance of 5G. Our research aims to help the industry better prepare for this next-generation technology, enabling developers to design new experiences that can be delivered through 5G-enabled devices.â€
Qualcomm carried out two independent network simulations. The first took place in Frankfurt, Germany, using a 3.5 GHz spectrum with a 100 MHz bandwidth, while the second was conducted in San Francisco, California, utilizing a 28 GHz millimeter-wave spectrum with an 800 MHz bandwidth. Both experiments used existing base station locations to co-locate 5G and LTE infrastructure, simulating realistic conditions for users.
In the Frankfurt test, the downlink capacity increased by up to five times when transitioning from a pure LTE network to a hybrid 5G/LTE setup. Spectral efficiency also improved significantly, showcasing the benefits of advanced technologies like massive MIMO.
Users experienced dramatic improvements in their 5G experience, including:
- Browsing download speeds jumping from 56 Mbps on 4G to over 490 Mbps on 5G.
- Browsing delay reduced from 116 ms to 17 ms.
- 90% of 5G users achieved download speeds above 100 Mbps, compared to just 10% of LTE users.
- Streaming video quality upgraded from 2K/30 FPS/8-bit color to 8K/120 FPS/10-bit color.
In San Francisco, the results were even more impressive, with 5G users experiencing browsing speeds of 1.4 Gbps—nearly 2000% faster than 4G. Delay was reduced by 23 times, and 90% of 5G users had download speeds exceeding 186 Mbps.
These experiments not only demonstrated 5G’s superior performance but also showed its ability to support a wide range of future applications beyond traditional web browsing and streaming.
Over 18 global operators and 20 leading device manufacturers have already selected Qualcomm’s X50 5G modems for early 5G trials and consumer devices, signaling strong industry readiness for 5G adoption in 2019.
**About the Simulation Methodology**
The 5G network simulations leveraged Qualcomm’s advanced modeling capabilities to replicate real-world conditions. Over 14,000 user terminals were distributed across the network, with 50% indoors and 50% outdoors. Traffic patterns were based on real-world mobile apps such as browsing, cloud storage, and video streaming.
Base stations were modeled with accurate RF characteristics, including massive MIMO configurations with up to 256 antennas for sub-6 GHz 5G and 256-element panels for millimeter-wave beamforming. Propagation models included detailed urban microcells, accounting for path loss, diffraction, and building penetration.
To reflect real-world interference, the simulations also considered Wi-Fi users in LTE unlicensed bands. These efforts ensured that the results closely mirrored actual network performance.
From February 26 to March 1, attendees at the Barcelona World Mobile Congress can view the live network simulation demo at Qualcomm’s booth in Hall 3E10.
