      OPPO was among the first to show a prototype smartphone lacking any physical buttons on the case. However, the company is exploring various options for form factors. For example, one of the patents of a Chinese manufacturer describes a smartphone with a plug-in physical QWERTY keyboard.

      Smartphones with keyboards are not new, they existed 20 years ago. A striking example is the Nokia 9210. And although this type of typing still has fans, many have completely switched to on-screen typing. Therefore, OPPO has come up with a special case with a built-in QWERTY keyboard that can be used if necessary.

      According to the presented image, the case will allow you to turn your smartphone into a small laptop. The built-in physical keyboard can be useful for typing or business correspondence.
      There are no guarantees yet that OPPO will decide to make this idea a reality and release a similar case for one of its smartphones.

      MIMO (Multiple Input Multiple Output, multichannel input – multichannel output) – a method of coordinated use of multiple radio antennas in wireless network communications, common in modern home broadband routers and cellular networks LTE and WiMAX.
      Table of Contents
      How does it work? MIMO in Wi-Fi SU-MIMO and MU-MIMO MIMO and cellular Multi-user technology Brief history: SU-MIMO vs MU-MIMO Advantages of MU-MIMO MU-MIMO restrictions Massive MIMO Concept MIMO technology: advantages and disadvantages How does it work?
      Wi-Fi routers with MIMO technology use the same network protocols as conventional single-channel routers. They provide better performance by improving the efficiency of wireless data transmission and reception. In particular, the network traffic between the clients and the router is organized into separate streams transmitted in parallel, with their subsequent recovery by the receiving device.
      MIMO technology can increase bandwidth, range, and transmission reliability with a high risk of interference from other wireless equipment.

      MIMO in Wi-Fi
      MIMO is included as standard with 802.11 n. It improves the performance and availability of network connections compared to conventional routers.
      The number of antennas may vary. For example, MIMO 2x2 provides two antennas and two transmitters capable of receiving and transmitting on two channels.
      To take advantage of this technology and realize its benefits, the client device and the router must establish a MIMO connection. The documentation for the hardware you are using should indicate whether it supports this feature. There is no other easy way to check if this technology is used in a network connection.
      SU-MIMO and MU-MIMO
      The first generation of technology introduced in the 802.11 n standard supported the single-user (SU) method. Compared to traditional solutions, where all the antennas of the router need to be coordinated to communicate with one client device, SU-MIMO allows you to distribute each of them among different equipment.
      Multi-user (MU) MIMO technology was created for use in 802.11 ac Wi-Fi networks at 5 GHz. If the previous standard required routers to manage their client connections alternately (one at a time), MU-MIMO antennas can provide communication with multiple clients in parallel. The multi-user method improves the performance of connections. However, even if the 802.11 ac router has the necessary hardware support for MIMO, there are other limitations:
      a limited number of simultaneous client connections (2-4) are supported depending on the antenna configuration; antenna coordination is provided in only one direction – from the router to the client.
      MIMO and cellular
      The technology is used in different types of wireless networks. It is increasingly being used in cellular communications (4G and 5G) in several forms:
      Network MIMO - coordinated signal transmission between base stations; Massive MIMO - the use of a large number (hundreds) of antennas; Millimeter waves - the use of microwave bands, in which the bandwidth is greater than in the bands licensed for 3G and 4G. Multi-user technology
      To understand how MU-MIMO works, you should consider how a traditional wireless router handles data packets. It does a good job of sending and receiving data, but only in one direction. In other words, it can only communicate with one device at a time. For example, if you're downloading a video, you can't stream an online video game to your console at the same time.
      The user can run multiple devices on a Wi-Fi network, and the router very quickly takes turns forwarding bits of data to them. However, at the same time, it can only access one device, which is the main reason for reducing the quality of the connection if the Wi-Fi bandwidth is too low.

      Since it works, the attention is paid little. However, you can improve the performance of a router that sends data to multiple devices at the same time. At the same time, it will work faster and provide more interesting network configurations. That's why there were developments like MU-MIMO, which were eventually incorporated into modern wireless standards. These developments allow the advanced router to communicate with several devices at once.
      Brief history: SU-MIMO vs MU-MIMO
      Single-and multi-user MIMO is different ways of communicating routers with multiple devices. The first one is older. The SU standard allowed the sending and receiving of data on several streams at once, depending on the number of antennas available, each of which could work with different devices. SU was included in the 2007 802.11 n update and began to be gradually introduced into new product lines.
      However, SU-MIMO had limitations in addition to the antenna requirements. Although multiple devices can be connected, they still deal with a router that can only work with one at a time. Data rates have increased, interference has become less of a problem, but there is still much room for improvement.
      MU-MIMO is a standard that has evolved from SU-MIMO and SDMA (multiple access with spatial channel separation). The technology allows the base station to communicate with multiple devices using a separate thread for each of them as if they all have their own router.
      In the end, the MU support was added to upgrade to 802.11 ac in 2013 After several years of development, manufacturers began to include this feature in their products.

      Advantages of MU-MIMO
      It's fascinating technology because it has a significant impact on the everyday use of Wi-Fi without direct changes in throughput or other key parameters of the wireless connection. Networks are becoming much more efficient.
      To ensure a stable connection to a laptop, phone, tablet, or computer, the standard does not require multiple antennas on the router. Each such device may not share its MIMO channel with others. This is especially noticeable when streaming video or performing other complex tasks. The speed of the Internet subjectively increases, and the connection is established more reliable, although, in fact, it becomes more reasonable to organize the network. The number of simultaneously serviced devices is also increasing.
      MU-MIMO restrictions
      Multi-user multi-access technology has a number of limitations, which are worth mentioning. The existing standards support 4 devices but allow you to add more and they will have to share the stream, which brings back to the problems of SU-MIMO. The technology is mainly used in downlink and is limited when it comes to outbound. In addition, the mu-MIMO router must have more information about the devices and the state of the channels than the previous standards required. This makes it difficult to manage and troubleshoot wireless networks.
      MU-MIMO is also a directional technology. This means that 2 devices located side by side cannot use different channels at the same time. For example, if a husband is watching an online broadcast on TV and his wife is nearby streaming a PS4 game to their Vita via Remote Play, they'll still have to share bandwidth. The router can only provide discrete flows to devices that are located in different directions.

      Massive MIMO
      As we move towards fifth-generation (5G) wireless networks, the growth in the number of smartphones and new applications has led to a 100-fold increase in their required bandwidth compared to LTE. The new Massive MIMO technology, which has received a lot of attention in recent years, is designed to significantly increase the performance of telecommunication networks to unprecedented levels. With the scarcity and high cost of available resources, operators are attracted by the opportunity to increase bandwidth in frequency bands below 6 GHz.
      Despite significant progress, Massive MIMO is far from perfect. Technology is still being actively explored in both academia and industry, where engineers seek to achieve theoretical results through commercially acceptable solutions.
      Massive MIMO can help solve two key problems – bandwidth and coverage. For mobile operators, the frequency range remains a scarce and relatively expensive resource, but it is a key condition for increasing the speed of signal transmission. In cities, the interval between base stations is due to capacity rather than coverage, which requires the deployment of a large number of them and leads to additional costs. Massive MIMO allows you to increase the capacity of an existing network. In areas where the deployment of base stations is driven by coverage, the technology increases their range.

      Concept
      Massive MIMO radically changes the current practice, using a very large number of coherent and adaptively operating 4G service antennas (hundreds or thousands). This helps to focus the transmission and reception of signal energy in smaller areas of space, greatly improving performance and energy efficiency, especially when combined with the simultaneous scheduling of a large number of user terminals (tens or hundreds). The method was originally intended for time-division duplex transmission (TDD), but can potentially also be used in the mode of duplex (PDD) frequency division.
      MIMO technology: advantages and disadvantages
      The advantages of the method are the widespread use of low-cost low-power components, reducing latency, simplifying the level of access control (MAC), resistance to accidental and intentional interference. The expected throughput depends on the propagation medium providing asymptotically orthogonal channels to the terminals, and experiments have so far revealed no limitations in this regard.
      However, along with the elimination of many problems, there are new ones that require urgent solutions. For example, in MIMO systems it is necessary to ensure effective collaboration of many inexpensive components of low accuracy, to collect data on the state of the channel and to allocate resources for the newly connected terminal. It is also necessary to use the additional degrees of freedom provided by the excess of service antennas, reduce internal power consumption to achieve overall energy efficiency and find new deployment scenarios.

      The increase in the number of 4G antennas involved in the MIMO implementation usually requires a visit to each base station to change configuration and wiring. The initial deployment of LTE networks required the installation of new hardware. This made it possible to configure the MIMO 2x2 of the original LTE standard. Further changes to base stations are made only in extreme cases, and higher-order implementations depend on the operating environment. Another problem is that the MIMO operation results in completely different behavior on the network than previous systems, which creates some scheduling uncertainty. Therefore, operators tend to use other developments first, especially if they can be deployed by updating the software.

      The SD Association, a non-profit organization responsible for the creation of memory card standards, presented the new microSD Express format at MWC 2019. It received a second series of contacts and support for NVMe 1.3 and PCIe 3.1 interfaces used in high-speed solid-state drives for personal computers. Thus, the new memory cards will provide data transfer at much higher speeds.
      microSD Express supports a maximum speed of up to 985 MB/s while maintaining backward compatibility with the previous standard. Such cards will be offered in different versions: microSDHC Express, microSDXC Express, and microSDUC Express. 

      In addition to the increased data transfer rate, microSD Express cards are also more energy efficient in comparison with standard microSD cards. They will support the power-saving mode L1.1 and L1.2 defined in the PCIe 3.1. They also have the ability to interact with other components without checking communication with the processor, which significantly speeds up multitasking.
      The timing of the emergence of the first cards of the format microSD Express has not yet been announced.

    • OPPO Reno 3 review: Quad camera and lots of memory

      Last year's OPPO Reno 2 smartphone was remembered for its almost flagship characteristics. In the new generation, the emphasis has shifted - the role of the top-end device has been assigned to the Reno 3 Pro, and the standard “three” has become a mid-budget phone. However, Reno 3 received a powerful quad camera, high-quality screen, and a large amount of memory. We find out how good the new product is.

      Four rear modules and a 44-megapixel front-facing camera
      The main camera of Reno 3 received four modules, as in the top-end device of the series - Reno 3 Pro. However, there are some functions missing, such as interpolation up to 108 MP. All the blocks are arranged in a line on an islet that protrudes noticeably upwards if you wear the gadget without a cover.
      The main module has a 1/2-inch sensor with a resolution of 48 MP and a lens with an aperture of f/1.8. As usual, in standard mode, it produces 12-megapixel images, and if desired, you can take photos in full resolution - 48 MP. Telephoto is based on a 13-megapixel sensor and a lens with an f/2.4 aperture. The ultra-wide Angle is equipped with an 8-megapixel sensor and a lens with an f/2.2 aperture. Finally, the 2 MP sensor is designed to assess the depth of the scene.

      Telephoto, in addition to 2x optical zoom, provides a 5x hybrid zoom. The photo app allows you to quickly switch between four shooting modes: ultra-wide angle, 1x, 2x, and 5x.
      All modules can function together with HDR. This option works perfectly in Auto mode, improving both the light and dark tones of contrasting scenes. Artificial intelligence confidently recognizes the scenes being shot and selects settings.
      However, in non-standard lighting conditions, if you choose wide-angle optics, the color rendering will not always be accurate. This does not happen with the main module and the telephoto lens.

      The main module paired with the auxiliary module gives clear portraits and realistic blurs the background
      Reno 3 shoots well in mixed and artificial lighting, as well as in the absence of light in the dark. In the most problematic cases, the Night program helps out. It combines several shots and works out all the tones of contrasting scenes. For shooting with manual settings, an Expert preset is provided.
      Multi-megapixel selfies
      The front camera is built into the display and is located in the middle of its upper edge, in the "drop". The camera is equipped with a 44-megapixel sensor and a wide-angle f/2.4 aperture lens. The default settings are set to a 40-megapixel resolution of images. And the full one is selected by pressing a separate on-screen button. The image quality in both cases is approximately the same. Sharpness appears only from a distance of about 30 cm, that is, for example, it is impossible to obtain a macro photograph of your eye. It seems that the calculation was made for shooting with outstretched hands or a selfie stick. For self-portraits, there are traditionally many beauty options: smoothing the skin, correcting the shape of the face and nose, eye size, and so on.

      Selfies in 44MP mode
      The smartphone records 4K videos at 30 fps. The supported format is Full HD with 30 and 60 fps, as well as slow-motion clips in HD and Full HD. During movie shooting, you can freely switch the zoom.
      In 4K mode at 30 frames per second, the gadget produces a picture with the correct color reproduction and high definition. But when working with hands, stabilization is noticeably lacking.
      Shooting in Full HD at 60 fps uses Ultra Steady Video 2.0 stabilization, which makes the picture smoother.
      Work and entertainment without lags
      Reno 3 is built on an eight-core MediaTek Helio P90 chipset. The new product in AnTuTu gives out figures comparable to the results of Kirin 970 and Snapdragon 712, and slightly ahead of Snapdragon 710. And in the Geekbench 5 rating - is on par with Snapdragon 845. This speed is sufficient to avoid slowdowns in any applications.
      8 GB of RAM allows you to run multiple programs simultaneously. The built-in fingerprint sensor acts quickly and accurately. There are no performance problems in games. In the popular WoT: Blitz with default graphics settings, the frame rate is confidently kept at 60 fps.

      The device has only one main speaker, which produces clear sound without distortion up to about 90% of the volume. Plus, there is support for Dolby Atmos. In this software add-on, you can add surround sound and a bit of bass - a great option for multimedia applications.
      Unfortunately, you will not be able to create a full stereo pair, because the speaker is quieter than the main one. But in Reno3 Pro two speakers shake as if you are holding a good Bluetooth speaker in your hands. Complete in-ear headphones deliver high-quality sound. Thanks to the audio jack, you can connect your favorite accessory.

      The built-in storage is not too large: 128 GB. But it is easy to increase it by using a microSD memory card. It is placed in a triple slot next to two nano-SIM cards. We had a 512 GB test card at hand - it worked without problems.
      High autonomy
      The gadget is powered by a 4025 mAh battery and supports VOOC 3.0 fast charging technology. A 20 W adapter and a complete cable during the test provided recharging at high speed. For example, from 33 to 78%, the battery was charged in 13 minutes, and up to 100% in 27.
      An hour-long shootout in WoT: Blitz (display brightness - 50%) consumes 11 percent of the battery. That is, without going to the outlet, it is about 9 hours of offline gaming. In Flight-mode, with the same brightness, about 4.4% of the battery charge is spent per hour playing the video in Full HD. Therefore, you should expect 22 hours of offline video viewing. Excellent results!

      If long-term autonomy is not so important, you can disable power consumption optimization in the settings and select "High performance". In this case, the device will work a little faster, and the battery consumption will be stronger.
      Great screen
      Reno 3 is equipped with an AMOLED panel with a diagonal of 6.4 inches, a resolution of FHD+ (2400x1080 pixels), and an aspect ratio of 20:9. The display occupies 90.8% of the front panel area, has a teardrop-shaped cutout for the front and thin frames. The image is clear, with rich but natural colors. The viewing angles are large, and the brightness reserve is sufficient for using the phone on the street in any weather. With minimal screen light, it is comfortable to read in a dark room. And at night, you can switch to "Dark mode" - in fact, this is an inverse version of the design: with a black display and a white font. Many people will find it even more convenient, and it also saves battery life.
      Branded shell of the seventh version
      Reno 3 is running a proprietary ColorOS 7 shell based on Android 10. When comparing with the previous version, you can see that the font has not changed, but many icons have been redrawn. However, their shape and size can be easily changed at your own discretion. The screen can be converted to a split format - just make a three-finger swipe up.
      Specifications of OPPO Reno 3
      DISPLAY: 6.4 ", FHD + (2400x1080), 20: 9
      CHIPSET: CPU MediaTek Helio P90 (MT6779V), 2.2 GHz, GPU PowerVR GM 9446

      Summary
      The OPPO Reno 3 is an interesting device with balanced characteristics. From the first minutes, the beautiful design, slim body, and high-quality 6.4-inch screen make you happy. Later on - high performance, fast recharging, and good battery life. The advantages include the photo-filling, including a 44-megapixel front camera. In addition, the built-in drive can be expanded with a memory card, but not to the detriment of the second SIM card - a trifle, but nice.
