    The Internet of Things has evolved tremendously in the last decade or so, although this is more gradual evolution rather than revolution so can be hard to notice the change. Ten years ago smartwatches, smart speakers, smart earbuds, smart thermostats, connected cars and consumer drones were not a thing. Today, many of these are what we consider everyday devices. 5G will continue fueling this trend with more capabilities including 5G light for IoT devices requiring ~100 Mbps, 5G V2X for vehicle-to-everything communications, and support for high-reliability and positioning for industrial applications. I see a day in which 5G is treated like electricity today... adaptable to virtually any use case and used to connect things without much thinking about it.

    One thing to notice is that many of the connectivity and compute technologies that support the IoT come from the smartphone revolution. Not just 5G but areas such as low-power device architechtures, Bluetooth, heterogeneous computing, efficient on-device... they come and achieved scale thanks to the cell phone. With more mobile connections than people on Earth, the mobile industry is uniquely positioned to develop and scale the technologies that feed other areas of the economy, such as the IoT.

    Given the short range of 5G mmWave technology, the carrier partners that we've talked to that are deploying mmWave have indicated that they intend to concentrate on high density areas or locations with low obstruction possibilities, such as the inside of stadiums or central city squares where residents tend to congregate. With longer range of 5G Sub-6 technology, carriers would deploy Sub-6 similar to their current LTE deployments which means broader coverage to reach most residents in a particular city. So we expect that over time, users will have reliable Sub-6 coverage in their everyday lives but be able to experience blazing fast mmWave speeds in select special locales.

    First, Wi-Fi is with us for the long run. Many people debate about the capabilities of Wi-Fi vs. 5G, but what we will see is that they're largely complementary and will co-exists for a very long time.

    5G is particularly well suited for dense public environments, such as a stadium or concerts (when we can attend those again). The fact that 5G uses (for the most part) licensed spectrum, the use of mmWave and the scheduled-resource nature of cellular systems allow for the extreme capacity required when many people is attempting to access high-bandwith applications at the same time. 5G also provides the performance, features and reliability required for industrial applications, cloud-dependent enterprises and vehicle-to-vehicle communications.

    In enterprises using private or dedicated 5G networks, small cells based on new virtual radio access network (vRAN) architectures will enable an easier integration with the underlying IT infrastructure. vRAN-enabled 5G mmWave will support 5G PCs with gigabit speeds using cellular-grade security to make bandwidth-intensive tasks (such as transferring large files, video calls, remote desktop, backup to cloud) faster and well protected. 5G mmWave can make remote storage feel as seamless as local storage – boosting the way users create, collaborate and communicate for enhanced productivity and competitiveness especially enterprises rely more and more on cloud applications (e.g. OneDrive). vRAN is important for enterprise applications because it allows the design of small 5G mmWave radio heads that can be collocated with Wi-Fi access points where backhaul and power is already available – supporting a quick rollout with superb coverage and performance.

    When Indian telecom carriers are ready to begin their expansion of 5G technology, Google will be ready to work with them to provide the necessary information to the platform to enable the 5G developer ecosystem in India. We will also be able to share with them best practices on making the most out of their 5G networks, whether that is ways to optimize certain types of network traffic or providing upgrade options that benefit users and carriers alike.

    Yes. Many operators are already committed with deploying broad coverage or nationwide 5G networks... starting as early as this year. This is facilitated by the ability to use 5G in lower frequency bands that can provide wide area coverage, particularly with the use of Dynamic Spectrum Sharing (DSS) which allows concurrent operation of legacy 4G and 5G in the same spectrum bands. The use of 5G in lower bands and DSS have been pioneered with Snapdragon Modem-RF systems... and those capabilities are available in the wave of 5G smartphones launching this year including the OnePlus 8-series.

    Another way that 5G will benefit rural areas is through Fixed Wireless Access, a fancy term to talk about providing fixed internet access to homes, schools and businesses using 5G infrastructure rather than fiber, cable or DSL which is not economically feasible in many rural areas. Qualcomm announced last year new 5G mmWave antenna modules specifically designed to support high-speed Fixed Wireless Access with extended-range.

    4G specifications already include capabilities to support low-power IoT applications -- these are the eMTC and NB-IoT modes which can support operation for up to 10 years using a couple of AA batteries. 5G will extend support for these modes, and introduce 5G NR-Light — a new class of devices that is more capable than eMTC/NB-IoT but supports different features and smaller bandwidth compared to today's 5G. For example, NR-Light can occupy just 10 or 20 MHz of bandwidth and deliver 100 Mbps of downlink and 50 Mbps of uplink throughput, making it a suitable technology for use cases such as high-end wearables or industrial IoT cameras and sensors.

    5G also is defined to support integrated access and backhaul, which means that 5G not only connect the device but it's also use to connect the base station to the core network (e.g. via another base station that has fiber connectivity). This facilitates the deployment and expansion of the network to support all kinds of applications including those from IoT.

    With 5G standalone networks, game developers can expect great improvement in the round-trip-time when networks are ready to enable the ultra low latency features. Cloud gaming fans will certainly benefit from these latency reductions as well as the expected improvement in 5G coverage means more on-the-go game play wherever you are.

    Game developers, esports promoters, and creators of massive multiplayer games can take advantage of the higher bandwidth and lower latency to offload compute to the cloud. Cloud gaming services including Google Stadia where all of the processing occurs in the cloud freeing developers from the constraints of on-device CPU/GPUs can enable same level of gaming experience in 5G now. But it also enables hybrid scenarios in which specific intensive algorithms are offloaded to the cloud.

    Finally, many AAA games are often 2+ GB, which can be very imposing for users to download on the go. On a typical LTE connection it could take over 20min. On public wifi, potentially even longer. 5G can do so in under 90 sec, which can mean the difference between acquiring or not acquiring a user.

    In the U.S., many traditional fixed line providers are also cellular carriers (examples - AT&T, Comcast, Verizon). These providers are actively exploring or have aspirations to provide fixed line service via 5G to homes as a way to solve for the last-mile hurdle of having to lay fiber or cable lines directly to each household. With internet service inside the home being provided by cell towers, 5G could power smart homes fluidly across all screens. This means all of the benefits of 5G on mobile phones could be extended to your home entertainment devices as well. Your entertainment bundle could be accessed seamlessly across devices which allows you to pick up where you left off across any screen or device. The user experience can be powered and controlled hands free via Voice and Google Assistant allowing you to consume media while you multitask. In the UK, people are already buying home 5G plans as well as people using their mobile's 5G connection to augment their existing home connection.

    5G is a new kind of network that will not only enhances today’s mobile broadband services but will also support a vast diversity of devices and services and connect new industries with features to support mission-critical communications and huge number of devices connected to the network. 5G will redefine a broad range of industries from retail to education, transportation to entertainment, and everything in between. It's see as transformative as electricity was in the 20th century.

    A 5G Economy study supported by Qualcomm found that 5G’s full economic effect will be realized across the globe by 2035, supporting a wide range of industries potentially producing more than $13 trillion worth of goods and services.

    Fixed Wireless Access (FWA) to provide internet connectivity in homes, schools, small businesses and rural areas is probably one of the first applications where we will see 5G beyond phones. For many mobile operators who will deploy 5G infrastructure anyways to serve mobile customers, it makes a lot of sense to expand their business to FWA now that 5G can provide speeds comparable to those from fiber, cable or DSL -- particularly using mmWave.

    I expect 5G FWA taking off as early as this year in many countries, emphasized by the realization that connectivity is more important than ever these days. In fact, there are already more than 30 OEMs working on FWA equipment using Snapdragon 5G Modem-RF Systems.

    Google has always believed that "fast is better than slow" It's in one of our oldest philosophy documents: https://www.google.com/about/philosophy.html Several Google product teams are working together to establish a roadmap of innovative 5G features and experiences for our users. For example, the AR team in Search is bringing Google Search results to life by allowing users to view high quality 3D objects and placing them in your space. With 5G, users can expect decreased load times and the ability to download larger, high fidelity assets without having issues like latency or bandwidth restrictions. With Google Lens, we can offer users immersive experiences over a 5G connection which could result in interactive store experiences making discovery, navigation, and purchasing frictionless. With Duo, 5G enables resolution improvements in video calling. With YouTube, users can enjoy 4K everywhere even if live streaming. The possibilities are endless and we are looking forward to seeing most of these experiences go live!

    We are only a year in the rollout of 5G networks. 5G is designed to evolve, with new features and capabilities rolling out over the next decade. Operators in are taking diverse approaches to their 5G deployments – some starting with 5G mmWave for extreme capacity and multi-gigabit speeds in dense areas, others using mid-bands for city-wide coverage and faster connectivity, others prioritizing low-bands to offer 5G nationwide.

    Despite their different initial approaches, all major operators are expected to use a combination of high, mid and low bands to provide both nationwide 5G coverage and multi-gigabit speeds – starting as soon as this year.

    Another key operator milestone for 2020 includes the start of the transition to 5G standalone which brings new capabilities such as network slicing that allows customized network performance in areas such as automotive, enterprise and industrial applications.

    In 2021, we expect that operators will aggregate their diverse spectrum assets including mmWave + sub-6 to lift 5G performance, and in the future new releases of the 5G specifications will allow for more capable 5G private networks, ultra-reliability for industrial IoT applications, enhancements in vehicle-to-everything communications, 5G in unlicensed spectrum and more.

    Google has been working to develop platform-level optimizations that can help extend battery life across multiple releases of Android and many newer phones (like the OnePlus 8 Pro) have larger batteries than their predecessors so this isn't an apples to apples comparison. In some situations you'll even see battery life improvements on 5G since if you don't have to spend 20 minutes to download a game you'll save battery life. We don't expect 5G devices to have worse battery life than their predecessors.

    5G brings more than 10x faster wireless speeds. The speed will vary depending on your device and your carrier but in our own real-world testing with production devices we've seen speeds of hundreds of megabits for downloads.

    @Zach X. how come OnePlus has stickied posts for the AMA that don't follow the direct rules given? Most of the stickied posts are tagging two people and asking two questions. When you specifically say tag the guest you want the answer from, and that you are only allowed to ask one question. Rules of the AMA -

    Thank you for your response. :) Definitely looks like a big machine with many parts moving together and coordinating such efforts. It is great to see the collaborations throughout the ecosystem and the efforts to make it used broadly while expanding 5G in the long term. I also enjoyed hearing about the rural areas. It is interesting to see where things are at in the development areas and throughout the ecosystem and compared to the infrastructure locally. :) I appreciate you and @Ignacio Contreras for taking your time, answering questions, and enlightening us on the 5G world.
