    DeZire

    Qualcomm introduced the third generation of the Snapdragon X60 5G Modem-RF System, which combines a modem with an antenna. The Snapdragon X60 is the world's first modem block implemented using a 5-nm process technology. In addition, it is the world's first modem system that supports frequency aggregation across all key 5G bands and their combinations.

    Qualcomm's new 5G modem allows data transfer at speeds up to 7.5 Gbit/s

    The Snapdragon X60 is designed to speed up the transition to standalone (SA) 5G mode: it supports key frequency ranges, modes, and combinations of them, including mmWave and sub-6 with time division duplex (TDD) and frequency division duplex (FDD) separation, as well as voice transmission in the 5G NR network (5G Voice-over-NR, VoNR). It allows you to increase the average data transfer rate for mobile 5G devices.

    To maximize performance in the mmWave range, Snapdragon X60 uses a new third-generation Qualcomm qtm535 mmWave antenna module. It is more compact, which will reduce the thickness of smartphones.

    In addition to 5g FDD-FDD and TDD-TDD carrier aggregation and dynamic spectrum separation, Snapdragon X60 implements the world's first 5g FDD-TDD sub-6 carrier aggregation solution. Thus, operators can choose different deployment options, including using LTE frequencies for 5G communications, thereby increasing average transmission speeds and expanding the scope of new generation networks.

    According to Qualcomm, the Snapdragon X60 provides wireless Internet over fifth-generation networks with speeds and latency comparable to fiber-optic transmission. The modem supports download speeds of up to 7.5 Gbit/s and upload speeds of up to 3 Gbit/s, while frequency aggregation in the Sub-6 range in 5g offline mode allows you to get twice the peak data transfer rates compared to solutions without frequency aggregation. VoNR voice support on the Snapdragon X60 platform, which allows operators to offer high-quality voice transmission in 5G NR networks, will be an important step towards the global transition of the mobile industry from non-autonomous mode to autonomous mode. All of this will help you deploy the next generation of connected apps and features, from multiplayer games and round-the-clock videos to connected cloud computing.

    Qualcomm's new 5G modem allows data transfer at speeds up to 7.5 Gbit/s

    Qualcomm also introduced the new ultraSAW RF filter technology. It emits radio signals in different frequency ranges used in mobile phones for receiving and transmission of information. By reducing insertion losses by at least 1 dB, Qualcomm ultraSAW surface acoustic wave (saw) filters are more efficient than a competing solution - filters based on bulk acoustic waves (BAW) in the range up to 2.7 GHz.

    Qualcomm's new 5G modem allows data transfer at speeds up to 7.5 Gbit/s

    Qualcomm ultraSAW technology achieves superior filter characteristics to deliver high performance in frequencies from 600 MHz to 2.7 GHz with a range of benefits:

    • Excellent transmit, receive and cross isolation
    • High-frequency selectivity
    • A Q-factor as high as 5000 or even higher – significantly higher than the quality factor of competing BAW filters
    • Very low insertion loss
    • Excellent temperature stability with very low-temperature drift in the single-digit ppm/Kelvin range.

    This allows for more power-efficient RF paths in 5G and 4G multimode mobile devices – and at a lower cost point than competing commercial solutions with similar performance metrics for original equipment manufacturers (OEMs).

    Qualcomm plans to start delivering samples of the Snapdragon X60 and QTM535 in the first quarter of 2020, and the appearance of commercial smartphones based on the new modem radio system is expected in early 2021. Production of a line of discrete and integrated products with support for Qualcomm ultraSAW will begin in the current quarter, and in the second half of 2020, the flagship OEM devices with this technology are expected to appear.

      Qualcomm held an extended presentation of the flagship Snapdragon 855 mobile chipset, which was announced during the first day of the Tech Summit technology conference. The novelty has become the world's first mobile 5g platform with high data transfer speed, advanced artificial intelligence functions, and significantly improved multimedia capabilities.

      The official specifications of the top 7-nm processor confirmed the previously published information. The eight Kryo 485 cores are divided into three clusters: a large 2.84 GHz core, three high-performance (2.42 GHz) cores, and four 1.8 GHz energy-efficient cores. CPU performance increased by 45% compared to Snapdragon 845. Increase the power of GPU Andreno 640 of its predecessor was 20%. Supported memory LPDDR4X with a frequency of 2133 MHz.

      Serious changes had been made to the ability of an artificial intelligence platform. Engine AI Engine 4th generation uses the hardware power of the GPU and the auxiliary processor Hexagon 690. Its overall performance is more than 7 trillion operations per second — three times that of the previous generation.

      The new Qualcomm Spectra 380 image processor uses AI algorithms to classify and track objects in the frame, including motion, both in the real world and in augmented reality applications. Installation of a single camera module with a resolution of 48 MP or dual with sensors of 22 MP is supported. Artificial intelligence is able to improve the image using filters and adjust autofocus, as well as post-processing of finished frames on the fly.
      The advanced voice assistant can cut off echoes and extraneous noise, distinguishing the voice of the device owner even on a busy street or stadium. The computer vision feature enables hardware depth detection when shooting 4K video at 60 frames per second. The user will be able to edit the video directly during its creation — for example, it will be possible to use the bokeh effect or replace the background in the frame of the future movie.

      For the first time for mobile devices support of the HDR10+ standard both for playback and for video recording is declared. Hardware acceleration of decoding and decoding of H. 265 and VP9 will provide high energy efficiency when playing multimedia files. Switching to hardware processing of multimedia files also significantly increases the energy efficiency of the platform.

      Especially for high-resolution content storage, support for the HEIF file format has been implemented, providing up to 50% disk space savings due to high compression efficiency at the best picture quality. Unlike JPEG, HEIF works not only with individual photos but also with groups of images and animated images.

      The platform's wireless capabilities are represented by a 5g Snapdragon X50 modem operating in the 6 GHz and mmWave frequency bands, as well as a 4G Snapdragon X24 module for compatibility with previous-generation networks. The modem has enough bandwidth to handle virtual and augmented reality up to 8K resolution and real-time video processing. The maximum download speed in the 5g coverage area can reach 5 Gbit/s, in LTE networks — up to 2 Gbit / s.

      Snapdragon 855 has received support for Wi-Fi standard 6 ready and MIMO technology for more efficient use of a large number of devices within the range of the access point. It is the first mobile platform to support 802.11a with wireless speeds of up to 10 Gbps with low latency.

      Audio capabilities of the chipset are represented by Qualcomm TrueWireless Stereo Plus technology for wireless headphones, which optimizes signal delay between the right and left channels and reduces power consumption. This will significantly increase the time to listen to music from a single battery charge when using True Wireless devices.

      A separate speech of the company's representatives was devoted to the gaming capabilities of the new platform.
      Currently, Qualcomm is already in talks with vendors. Oneplus CEO Pete Lau confirmed that the company will be the first to release a 5G smartphone early next year. It is expected that mass deliveries of Snapdragon 855 for commercial devices will begin in the first half of 2019.

      Every December Qualcomm presents new flagship processors and other developments. This year, the technology was just a breakthrough!
      Snapdragon 855: 7 nanometers and 60% more powerful
      In Snapdragon 855 Qualcomm switched to the use of advanced 7-nm process technology. As a result, devices based on this chipset will differ not only with increased power but also with improved energy efficiency and less heating. In comparison with Snapdragon 845 processor performance increased by 45%, and the graphics accelerator - by 20% (its detailed specifications can be found in our material).
      The new mobile platform has received hardware-level support for Qualcomm 3D Sonic Sensor built-in fingerprint scanner. Such a sensor is much more reliable and more accurate than the optical sensors currently used in smartphones.
      Smartphones based on Snapdragon 855 will be able to automatically improve photos taken with a lack of lighting, adjust the autofocus, and post-processing of finished frames without any delay.
      For the first time, mobile gadgets received support for extended dynamic range HDR10+ when playing and recording video.
      Snapdragon Elite Gaming: better graphics, lower power consumption in games
      Another important feature Snapdragon 855 — support new technology Snapdragon Elite Gaming. With it, games, especially multiplayer, will go much smoother by reducing frame loss to 90% and optimizing the use of Internet traffic. In addition, this technology reduces energy consumption by 20%, which is especially important for mobile gamers. Qualcomm also promises even more beautiful graphics in mobile games, HDR support, and cinematic post-processing.

      Snapdragon 855 in smartphones: so far only Xiaomi
      Several prototypes of smartphones based on Snapdragon 855 were presented at Snapdragon Tech Summit. But the device ready for commercial launch was demonstrated only by Xiaomi, showing the flagship Mi Mix 3 with 5g support. But the timing of its release and the cost was not reported.

      Also at the summit, the General Director of OnePlus Pete Lau spoke about the development of a new 5g smartphone based on Snapdragon 855. Such a gadget, as Lau notes, will cost $200-300 more than their existing models.
      Artificial intelligence and augmented reality
      Qualcomm paid attention to artificial intelligence and augmented reality technologies. In Snapdragon 855 uses a block of neural computing of the fourth generation, the performance of which has increased three times in comparison with its predecessor, and in comparison with competitors declared a twofold increase. For example, the delay in recognizing a page of text through the camera using Google Lens has decreased by three times, and the power consumption has decreased by 3.7 times.

      The use of artificial intelligence allows during video recording to include background blur, as on professional cameras. Or even replace the background-all this happens directly on the device, not on remote servers, as it is implemented in various applications. In addition, Snapdragon 855 supports accurate facial recognition at the hardware level.

      Devices based on Snapdragon 855 will receive a significant increase in capabilities when working with augmented and virtual reality due to hardware acceleration. Smartphones will be able to better recognize objects in the frame with the provision of useful information about them and will more naturally display virtual things in the real world.
      Fifth-generation networks: up to 1.5 Gbit/s
      Snapdragon 855 will be the first Qualcomm mobile platform to use a fifth-generation X50 modem. During a demonstration of the work of the modem, connection speeds were up to 1.5 GB/s. This is enough even for streaming video at a resolution of 8K. In addition to the increased speed of data transmission in the networks of the fifth generation of the signal passes through obstacles, including walls of the houses. This is due to the fact that the new standard operates in the millimeter range.

      It is expected that the commercial launch of 5G, which is scheduled for 2019, will accelerate the spread of the Internet of things, self-driving cars, and smart city systems.  The new standard provides low latency, which is very important for smart devices.
      Snapdragon 8cx: ARM processor specifically for laptops

      Two years ago, Qualcomm's first shared plans to release a Windows-laptops on the Snapdragon processor is Always Connected PC. For these mobile computers offered a "smartphone" chip 835-th line. But laptops with conventional mobile processors were released only a few models from a couple of manufacturers. And this year, Qualcomm introduced the world's first processor made specifically for devices Always Connected PC, Snapdragon 8cx. This chipset, also made by 7-nm process technology, has become the most powerful in the history of the company. Compared to the Snapdragon 850, its performance has doubled and energy efficiency has improved by 60%. In terms of power, it is comparable to the Intel Core u series processors, which are used in many laptops and 2-in-1 devices.
      The key advantage of Qualcomm ARM chips over x86 processors is significantly lower power consumption. According to the company, mobile computers based on Snapdragon 8cx in some scenarios will be able to work up to 25 hours without recharging.

      Also during the presentation, Qualcomm announced that Windows computers with Snapdragon 8cx processor will support many popular applications and services, including the Office Suite from Microsoft, Netflix, Spotify, VLC, Firefox, and many others.
      The first computers based on Qualcomm 8cx are expected to appear this year.

      The top mobile chipset Snapdragon 855 received not only 5G-modem and improvements in the field of AI computing. One of the key features of the new product was a significantly increased performance of the graphics component of the platform. Representatives of Qualcomm spoke in detail about the innovations that expanded the gaming capabilities of Android devices based on the new processor.

      Graphics accelerator Adreno 640 was 20% faster than its counterpart in the composition of the Snapdragon platform 845. Updating the hardware component of the chipset significantly accelerated the loading of games on mobile devices. In addition, the Snapdragon 855 architecture allows virtual and augmented reality games to function with 6 degrees of freedom to enhance the gaming experience of users.
      Increased performance in these applications is made possible by distributing the workload between the GPU, the Hexagon auxiliary processor, and the image processing unit (ISP).

      One of the main chips of the chipset was Snapdragon Elite Gaming technology. Qualcomm's hardware and software package includes support for the Vulkan 1.1 graphics library, which provides applications with the ability to directly control GPU operations without "crutches" in the form of third-party drivers.
      As a result, the loss of frames in mobile games can be reduced by 90%, making the picture much smoother. Especially noticeable performance improvement will be in multiplayer games.

      Another advantage of the Vulcan API is high energy efficiency. Compared to the software interface OpenGL achieved 20 percent savings in battery consumption of flagship smartphones based on the new Snapdragon.

      Thanks to the function of physically correct rendering (PBR), the interaction of light with surfaces in gaming applications looks as natural as possible. This technology is already used in PC-releases — with its introduction to the mobile market should expect a significant expansion of the list of ported to Android game hits.

      The computing power of the platform is enough to run games with HDR support and cinematic image post-processing. Representatives of the company compared modern smartphones with the traditional monitors-the picture quality of actual mobile displays is not inferior to many desktop solutions. If necessary, the image from the mobile device can be displayed on the external screen even in 4K resolution.

      An important component of online releases is connection stability. Snapdragon Elite Gaming technology includes a built-in quality of service (QoS) system that prioritizes game packages, preventing third-party applications from "pulling" traffic to themselves.

      The sound component is also of paramount importance in games, especially in multiplayer shooters. The latest version of the Qualcomm AptX codec guarantees high sound quality with a minimal delay even when using Bluetooth headphones. For the quality of the signal is a proprietary Qualcomm DAC Aquatic with features surround sound and noise reduction.
      The energy efficiency of the new platform has also improved significantly. Despite the increase in graphics power, the device based on Snapdragon 855 is able to work longer on a single battery charge than its predecessor.

      The emergence of new gaming smartphones with support for Snapdragon Elite Gaming technology is expected in 2019 with the beginning of commercial deliveries of Snapdragon 855.

      Qualcomm has not yet announced the Plus version of the flagship Snapdragon 865 processor, but insiders have already managed to get its technical specifications. Authoritative network informants Max Weinbach and Ice Universe almost simultaneously published specifications of the upcoming chip and called the smartphone, which will be one of the first devices based on the latest mobile platform.

      According to the editor of the XDA-Developers portal, the OCTA-core processor will be "split" into three clusters according to the scheme 4 x1.8 GHz + 3 x 2.4 GHz + 1 x 3.1 GHz. Thus, the new product will surpass the performance of its predecessor, which has a maximum clock frequency of 2.84 GHz. As a source of information, Weinbach points to the Geekbench database, where an unannounced Samsung Galaxy Note20+ was recently tested.
      Previously, it was assumed that the gadget will be built on the basis of Snapdragon 865, but further study of the entry code in the benchmark showed a higher frequency. A similar statement was later made by an Ice Universe insider, who came to the same conclusions.

      It is worth noting that these specifications have not yet been confirmed by Qualcomm - it is possible that an engineering prototype of a mobile processor has lit up in Geekbench, and by the time of release, its key characteristics may be changed by the manufacturer.

    • Search engine marketing (SEM): the methods, techniques, safety

      What is search marketing? A few years ago, this term simply did not exist. However, the rapid development of Internet technologies has led not only to the emergence of this trend but also to its amazing popularity. At the moment, search marketing is known as an effective way of promotion, which includes a range of activities aimed at achieving only one goal - to attract customers.

      Table of Contents
      Definition Relevance Goals and Tasks Methods and Technologies Search engine optimization Contextual advertising Social networks Search marketing security Prohibited method: Disadvantages Definition
      If you have not encountered this term before, it's time to get acquainted with it. Search engine marketing involves promotion in search engines in order to attract the target audience. I must say that this is a whole system in which several specialists are involved. They are marketers, programmers, copywriters, designers, etc.
      Compared to other methods of search engine marketing on the Internet has a major advantage. It allows you to reach out to an audience that is interested in the proposal addressed to it. This is due to the fact that it comes to the search engine for an answer to your request. Offering what potential visitors need, you both benefit. Customers get what they're looking for, and you get real customers.
      Relevance
      Search marketing is still a fairly new technology. Therefore, users have a logical question: why is it needed and whether it is needed at all? Let's find out.
      So, the main task of search marketing is to attract potential consumers. And not random, but only interested. After all, the offer is addressed only to those who are already looking for a product or service that you are ready to offer.
      However, in order for a user to notice your website among dozens of competitors, it is necessary to use various methods of search marketing. After all, as a rule, scrolling through the issue, the user rarely browses more than ten sites. Competently using the latest technology, you can be in the top ten and get ahead of competitors in the fight for the attention of potential customers.

      The theoretical definition does not always give an accurate understanding. Let's try to find out how search engine marketing works and what it's for.
      So, suppose that a budding entrepreneur decided to open his own business – to sell lingerie in an online store. This is a popular product that is in demand.
      However, in any area, you need advertising that allows you to attract customers. Because their absence means no profit. For start-up entrepreneurs, all costs are on the account, and any advertising is not cheap.
      There are many companies that offer search marketing among other services. You can even link the amount of payment to the result or make parts. That is, first the entrepreneur receives real customers, and then from the profits makes the rest of the payment for such an unusual method of advertising. Convenient to all.

      Goals and Tasks
      Knowing the definition is not enough. You need to know for what purposes search marketing is used.
      Sales. This is the most obvious task that this method of promotion performs. It is necessary to attract interested buyers to the site who will make a purchase. Image. The more often a person will see the logo of your company, the more likely that he will remember you and sooner or later become a client. Reputation. If we are talking about the promotion in social networks, a large value can have reviews. It is advisable to find a way to encourage buyers to leave real reviews. The more positive opinions can be collected, the greater the level of confidence in the company among potential customers. Competition. The market for goods and services is currently oversaturated. That is why it is especially important to compete and win customers over to your own side. Information. You can offer users up-to-date information about the products and services they are interested in. Even if they don't buy anything right away, your company will become an expert for them. In the future, they can return, choosing you among the many competitors.
      Methods and Technologies
      You need to understand that SEM (search engine marketing) is the whole complex of actions, which may include website optimization, contextual and launching viral advertising, and on the Internet resource work more effectively, attracting target customers and converting them into real buyers. So, what are the technologies of search marketing?
      Contextual advertising. Targeted advertising. Search engine optimization. Social network. Let's talk more about some of the technologies listed above.
      Search engine optimization
      This is only part of the marketing campaign. It involves working directly with the promoted site. Moreover, search engine optimization can be both internal and external. In the first case, work with texts published on the website, metatags, links, etc. In the second case, efforts are aimed at increasing the number of links to third-party resources.

      There are a considerable number of factors that allow you to improve the position of the site in search results. A simple user does not need to know all of them. To do this, there is a separate profession, representatives of which are engaged in search engine optimization.
      Contextual advertising
      This system for placing paid ads, created by the search engines. Each user can create their own ads and thus attract the target audience to their own website.
      The advantage of contextual advertising is that the user does not pay for the fact of placing an advertisement. Payment is charged only if the user clicked on the ad and went to the specified site.
      Another important feature is that to get to the top lines do not need long and painstakingly to optimize the site. You can buy this place for a fee, exhibited by the search engine. It is difficult to predict how high the conversion will be in this case.
      Social networks
      These sites are incredibly popular among the population. It is not surprising that this is quite successfully used by marketers. In this case, often published interesting for users' materials, to support communication in thematic communities, etc. In a sense, marketing in social networks can be called hidden. In addition, this method of advertising is not suitable for all companies. Not every product can be advertised with beautiful photos on social networks and enticing texts.

      Search marketing security
      This question becomes relevant if illegal methods of promotion are used. Conventionally, they are called "gray" and " black".
      Above were described exclusively "white" methods of search marketing, which are loyal to the search engines. Such a conscientious promotion requires a lot of time and effort, but ultimately increases the reputation of the site and gives a reliable result.
      Why then use "gray" and "black" schemes? For the reason that not all site owners are willing to invest a lot of time, effort, and money in the fair promotion. However, you need to understand that when using unscrupulous methods then it will be extremely difficult to restore the reputation of the site or even impossible.
      Prohibited method:
      spamming; automatic link exchange and purchase; placement of links to non-thematic sites. Some of these methods can produce results, but they can also lead to a site ban. Then it will disappear from the search results. Is it worth the risk, each site owner decides for himself.

      Disadvantages
      Delayed result. It may take several weeks of hard work to see the first results of search marketing. We must understand that this is a task that involves long-term implementation. Do not take it, waiting for lightning-fast results. Dependence on competitors. Even if as a result of well-organized search marketing you will be able to be in a good position in the issuance, all at any time can change because of the actions of your competitors. Complexity. It is almost impossible to carry out the whole complex of measures to promote the company on the Internet alone. This requires a whole team of professionals, not random people. Financial cost. You will have to pay for both professional services and search marketing. For example, if we are talking about contextual advertising. You need to understand that the promotion cannot be absolutely free.
