This year’s Mobile World Conference saw Qualcomm announce key findings from a 5G network simulation it has conducted over the past several months.
The Qualcomm Technologies’ 5G Network Capacity Simulation demonstrated the significant potential of 5G, by yielding quantitative insights into the expected real-world performance and user experience of 5G and Gigabit LTE devices, operating in Non-Standalone (NSA) multimode 4G/5G NR networks. The findings also provide quantitative support for the significant gains in capacity that can be realized by 5G NR over 4G LTE, as the industry prepares for the first wave of 5G networks and devices in the first half of 2019.
“There is a lot of interest from various stakeholders in the mobile ecosystem – cloud platform providers, application developers, device OEMs, and others – in understanding the real-world performance that 5G NR mobile networks and devices will deliver,” said Alex Holcman, senior vice president of engineering, Qualcomm Technologies, Inc. “We undertook this comprehensive study to help the ecosystem prepare for the foray into 5G, so that application developers, for example, can begin planning new experiences and services for users with 5G devices.”
Two separate sets of simulations were conducted. The first one, modeled a NSA 5G NR network in Frankfurt, Germany, operating on 100 MHz of 3.5GHz spectrum, with an underlying Gigabit LTE network operating across 5 LTE spectrum bands. The second simulation modeled a hypothetical NSA 5G NR network in San Francisco, California, operating in 800 MHz of 28 GHz mmWave spectrum, with an underlying Gigabit LTE network operating across 4 licensed LTE spectrum bands plus License Assisted Access (LAA) bands. In both simulations, existing cell site locations in Frankfurt and San Francisco were used, where 5G NR cell sites are co-located with actual, existing LTE sites.
The Frankfurt simulation showcased a downlink capacity increase of up to 5x when migrating from an LTE-only network, with a mix of LTE devices of various capabilities, to a 5G NR network with multi-mode 5G NR devices and an increased mix of advanced Gigabit LTE devices. This simulation also yielded compelling evidence of the benefits of Massive MIMO technology, with median spectral efficiency increase of up to 4x on 3.5 GHz spectrum.
Beyond network capacity improvements, the simulation also demonstrated significant user experience gains for 5G NR capable devices when compared with LTE devices, including:
- Browsing download speeds increasing from 56 Mbps for the median 4G user to more than 490 Mbps for the median 5G user, a gain of approximately 900 percent
- Approximately 7x faster responsiveness, with median browsing download latency reduced from 116ms to 17ms
- File download speeds of 100 Mbps for the 10th percentile 5G user, meaning that 90 percent of 5G users have download speeds of more than 100 Mbps. This is compared to 8 Mbps for the 10th percentile LTE user.
- Median streaming video quality increasing from 2K/30 FPS/8-bit color for LTE users to 8K/120 FPS/10-bit color and beyond for 5G users.
The San Francisco simulation, on the other hand, provided the first glimpse of the impact of the significantly increased capacity afforded by 800 MHz of additional mmWave spectrum on real-world user experience. Key findings included:
- Browsing download speeds increasing from 71 Mbps for the median 4G user to 1.4 Gbps for the median 5G user in mmWave coverage, a gain of approximately 2000 percent
- Approximately 23x faster responsiveness, with median browsing download latency reduced from 115ms to 4.9ms
- File download speeds of more than 186 Mbps for 90 percent of 5G users, compared to 10 Mbps for LTE, a 1,826 percent gain. The median 5G file download speed was 442 Mbps.
- Median streaming video quality increasing from 2K/30 FPS/8-bit color for LTE users to 8K/120 FPS/10-bit color and beyond for 5G users.
The results from the 5G Network Capacity Simulation lend credence to the promise of 5G, with expected real-world performance that is substantially better than what is currently possible with 4G across multiple metrics. The findings also illustrate that these emerging 5G networks will have the capacity and performance to support a whole host of new services and experiences beyond the traditional categories of browsing, downloading, and streaming. With 18 global operators and 20 leading device makers selecting the Qualcomm® Snapdragon™ X50 5G modem for the first wave of 5G network trials and consumer devices, the stage is set for these incredible 5G user experiences to come to user’s hands in the first half of 2019.
About the Simulation Methodology
The 5G Network Capacity Simulation builds on Qualcomm Technologies’ unique capabilities to accurately model and simulate cellular systems.
The Simulation utilized existing base station locations with the 5G NR cell sites co-located with existing LTE cell sites. Around 14,000 user devices, of various capabilities, were randomly distributed across the network with approximately 50 percent of the users indoor and 50 percent of the users outdoor. The mixture of devices, capabilities of devices, and spectrum bands/bandwidths utilized by the devices were all chosen based on anticipated commercial deployments for LTE-only and NSA 5G NR networks in the 2019 timeframe. The simulation showcased different traffic patterns based on a representative mixture of mobile applications including browsing, cloud storage downloading, and adaptive bitrate video streaming.
The simulations were based on modeling of the physical base stations and their RF capabilities, including Massive MIMO capability for 5G NR sub-6 GHz utilizing up to 256 antennas, and 5G NR mmWave beamforming utilizing antenna panels with 256 elements. The LTE-only traffic is modeled utilizing 4 antennas at the base station. The propagation between the base stations and the devices was modeled based on detailed 3D urban microcell and urban microcell models that include path loss, shadowing, diffraction, building penetration loss, and more, making use of the extensive over-the-air testing and channel measurements conducted by Qualcomm Technologies. To ensure the simulations reflect real-world mobile environments, they included modeling of interference from cells that were simultaneously serving different users, including accounting for Wi-Fi users to realistically model the use of LTE in unlicensed spectrum (LAA).
Facebook fakes behind most phishing attempts
In the first quarter of 2018, Kaspersky Lab’s anti-phishing technologies prevented more than 3.7 million attempts to visit fraudulent social network pages of which 60% were fake Facebook pages.
The results, according to the Kaspersky Lab report, ‘Spam and phishing in Q1 2018’, demonstrates that cybercriminals are still doing what they can to get their hands on personal data.
Social network phishing is a form of cybercrime that involves the theft of personal data from a victim’s social network account. The fraudster creates a copy of a social networking website (such as a fake Facebook page), and tries to lure unsuspecting victims to it, forcing them to give up their personal data – such as their name, password, credit card number, PIN code, and more – in the process.
At the beginning of the year, Facebook was the most popular social networking brand for fraudsters to abuse, and Facebook pages were frequently faked by cybercriminals to try and steal personal data via phishing attacks. This is part of a long-term trend: in 2017, Facebook became one of the top three targets for phishing overall, at nearly 8%, followed by Microsoft Corporation (6%) and PayPal (5%). In Q1 2018, Facebook also led the social network phishing category, followed by VK – a Russian online social networking service and LinkedIn. The reason for this is likely to be the worldwide 2.13 billion active monthly Facebook users, including those who log in to unknown apps using their Facebook credentials, thereby granting access to their accounts. This makes unwary Facebook users a profitable target for cybercriminal phishing attacks.
This all reinforces the fact that personal data is valuable in the world of information technology –both for legitimate organisations and attackers. Cybercriminals are constantly searching for new methods to hit users, so it’s important to be aware of fraudster techniques to avoid becoming the next target. For example, the latest trend is spam emails related to GDPR (Europe’s General Data Protection Regulation). Examples include offers of paid webinars to clarify the new legislation, or invitations to install special software that will provide access to online resources to ensure compliance with the new rules.
“The continuous increase in phishing attacks – targeting both social networks and financial organisations – shows us that users need to pay more serious attention to their online activities. Despite the recent global scandals, people continue to click on unsafe links and allow unknown apps access to their personal data. Due to this lack of user vigilance, the data on a huge number of accounts gets lost or extorted from users. This can then lead to destructive attacks and a constant flow of money for the cybercriminals,” said Nadezhda Demidova, lead web content analyst at Kaspersky Lab.
Kaspersky Lab experts advise users to take the following measures to protect themselves from phishing:
- Always check the link address and the sender’s email before clicking anything – even better, don’t click the link, but type it into your browser’s address line instead.
- Before clicking any link, check if the link address shown, is the same as the actual hyperlink (the real address the link will take you to) – this can be checked by hovering your mouse over the link.
- Only use a secure connection, especially when you visit sensitive websites. As a minimum precaution, do not use unknown or public Wi-Fi without a password protection. For maximum protection, use VPN solutions that encrypt your traffic. And remember: if you are using an insecure connection, cybercriminals can invisibly redirect you to phishing pages.
- Check the HTTPS connection and domain name when you open a webpage. This is especially important when you are using websites which contain sensitive data – such as sites for online banking, online shops, email, social media sites etc.
- Never share your sensitive data, such as logins and passwords, bank card data etc., with a third party. Official companies will never ask for data like this via email.
- Use a reliable security solution with behaviour-based anti-phishing technologies, such as Kaspersky Total Security, to detect and block spam and phishing attacks.
Other key findings in the report include:
- The main targets of phishing attacks have remained the same since the end of last year. They are primarily global Internet portals and the financial sector, including banks, payment services and online stores.
- About $35,000 USD was stolen through one phishing site that appeared to offer the opportunity to invest in the rumoured Telegram ICO. Approximately $84,000 USD was stolen following a single phishing email mailshot related to the launch of ‘The Bee Token’ ICO.
- Financial phishing continues to account for almost half of all phishing attacks (43.9%), which is 4.4% more compared to the end of last year. Attacks against banks, e-shops, and payment systems remain the top three, demonstrating cybercriminals’ desire to access users’ money.
- Brazil was the country with the largest share of users attacked by phishers in the first quarter of 2018 (19%). It was followed by Argentina (13%), Venezuela (13%), Albania (13%), and Bolivia (12%).
- In the first quarter of 2018, the amount of spam peaked in January (55%). The average share of spam in the world’s email traffic was 52%, which is 4.6% lower than the average figure of the last quarter of 2017.
- Vietnam became the most popular source of spam, overtaking the U.S. and China. Others in the top 10 included India, Germany, France, Brazil, Russia, Spain, and the Islamic Republic of Iran.
- The country most targeted by malicious mailshots was Germany. Russia came second, followed by United Kingdom, Italy, and the UAE.
