Most recently, Chinese telecom equipment and consumer electronics giant Huawei filed suit against the U.S. government on Thursday, alleging that a law passed last August banning the company's hardware is unconstitutional because it unfairly targets Huawei. The arms race between the two superpowers over the tech talent, physical infrastructure and industrial muscle--not to mention the IP that comes with the technologies--that will unlock these advancements has been increasingly evident in diplomatic machinations, public investments of varying size and outward rhetoric from state leaders, as each country's government has moved the technologies to the top of their respective economic agendas. These struggles are about more than economic opportunity alone. The shift to 5G networks, which promise to eventually reach speeds up to 100 times faster than what's currently available, could expand the role of wireless communications systems into everything from power grids to traffic, while AI is already facilitating the mass collection and processing of data that will power critical tools like autonomous driving and facial recognition. In that future state, control over telecom equipment and AI-powered data centers could be like holding the keys to a society.

Let's take a closer look at some of the most important, key take-aways from this year's MWC19 wireless conference in Barcelona. The theme was, "Intelligent Connectivity". The surprise was a sudden focus on folding-screen smartphones. However, the most important areas are the rapid move to 5G, AI and IoT. Plus, managing all the new technology that is coming at us at light-speed and more.

Not that I'm a big fan of such titles, but when I look at what 5G will bring, it's clear most businesses will feel the impact. Most technologies have a slow adoption curve. This change of speed is going to catch most companies unaware. The technological improvements of better connectivity are apparent, but their consequences aren't. There are two big groups of problems that 5G's lower latency and high bandwidth will impact. On one side, we have those problems that we can solve with low computation and real-time responses. Think of any remote controller. There is minor computation needs on the controller side but needs fast reactions on the remoter actuator.

Samsung is developing two new foldable phones as successors to its recently unveiled Galaxy Fold smartphone, a new report claims. Both devices will be significantly different from their predecessor in terms of their folding mechanics. Unlike the Galaxy Fold, which features a small screen on one side and a larger screen that unfolds from the inside like a book, Samsung plans to borrow a design used by its rival Huawei for one of the new phones. We'll tell you what's true. You can form your own view.

The following is a summary of predictions of the ICT trends for 2019, selected due to their impact on the networking industry and forecast what is expected to happen or start happening, within the next 12 months. "Intuition is nothing but the outcome of earlier intellectual experience", Albert Einstein As we enter the fourth year of the "Fourth Industrial Revolution" - the era of connected intelligence, our relationships with technology and its impact on global society will come into even sharper focus. The reality of the revolution is both promising and threatening. The primary new technologies of this decade – Artificial Intelligence (AI), cloud, mobile/5G, cybersecurity, blockchain and the Internet of Things (IoT) – are even more significant and impactful than we may realise. They are powerful actors that can change the core of society.

One of the fundamental challenges to realize massive Multiple-Input Multiple-Output (MIMO) communications is the accurate acquisition of channel state information for a plurality of users at the base station. This is usually accomplished in the UpLink (UL) direction profiting from the time division duplexing mode. In practical base station transceivers, there exist inevitably nonlinear hardware components, like signal amplifiers and various analog filters, which complicates the calibration task. To deal with this challenge, we design a deep neural network for channel calibration between the UL and DownLink (DL) directions. During the initial training phase, the deep neural network is trained from both UL and DL channel measurements. We then leverage the trained deep neural network with the instantaneously estimated UL channel to calibrate the DL one, which is not observable during the UL transmission phase. Our numerical results confirm the merits of the proposed approach, and show that it can achieve performance comparable to conventional approaches, like the Agros method and methods based on least squares, that however assume linear hardware behavior models. More importantly, considering generic nonlinear relationships between the UL and DL channels, it is demonstrated that our deep neural network approach exhibits robust performance, even when the number of training sequences is limited.

Need a new smartphone but don't know which one is the very best? Here's a guide comparing the current top-end smartphones from Apple, Samsung, Huawei and others to help you pick the best handset for you. There has never been a better time to buy a new flagship smartphone with many quality handsets available at a wider range of prices than ever before. Whether your priority is two-day battery life, fantastic camera performance or a spectacular screen, there's plenty to choose from. This Guardian buyer's guide to top-end smartphones was last updated on 6 March, and represents the best available models at the time. As new models are released and tested, this guide will be updated to help you choose the right flagship phone for you.

Mayor Darrell Steinberg says he hopes the new high-speed wireless service will attract businesses to the city. Mayor Darrell Steinberg says he hopes the new high-speed wireless service will attract businesses to the city. Sacramento Mayor Darrell Steinberg has a message for his neighbors to the south in Silicon Valley who might be sick of the high prices and overcrowding: "If you are a small business or an entrepreneur and you are trying to make it in in the Bay Area and you can't, don't move to Seattle -- move to Sacramento." One of the lures he's using to draw businesses is newly installed Verizon fifth generation, or 5G, wireless. Each generation of faster wireless speeds has helped spark innovation.

Oral-B has built a smart toothbrush that hopes to use artificial intelligence to improve the hygiene of its users. The brush connects via Bluetooth to a smartphone app and uses artificial intelligence and a combination of sensors to know where you are brushing and how to improve your technique. Dubbed the Genius X, it can provide customers with precise data as to which teeth are being neglected and when you are pushing down too hard. Prototypes were unveiled at Mobile World Congress in Barcelona and pricing has yet to be announced. It was featured at the technology showcase alongside a range of developments in 5G and foldable phones.

Huawei has launched a special "transparency centre" as it attempts to stop people being afraid of it spying on them. The new building in Brussels is an attempt to win back the government leaders and cyber security experts that are worried about its equipment, which powers much of the data connections of the world. Numerous governments have accused the company of using that infrastructure to intercept communications and send them back to the government in China, where it is based. We'll tell you what's true. You can form your own view.
