A piece of silicon less than three inches across may speed up the arrival of 5G mobile networks in the next few years. IBM Research and Ericsson have developed a compact antenna array that can aim high-frequency radio signals at mobile devices and shoot them farther than they otherwise could reach, the companies said. Silicon integration makes it thin and energy efficient so it's more commercially viable. Carriers expect 5G networks to deliver cellular data speeds in the gigabits per second, far faster than what today's LTE services offer. They also expect benefits like less power consumption, lower latency and the ability to serve a lot more devices at the same time.
Verizons 5G lab is creating new and innovative ways to take advantage of the speed of 5G. With 5G, however, things are going to be a little different. To be clear, you don't need to know the details of how 5G works to enjoy the potential speed increases and other cool capabilities it will eventually offer. However, you do need to be aware of some 5G basics to really understand what future smartphones, connected devices, and carrier plans are going to offer – and how they'll differ. Learning a bit about how 5G works – and why not all 5G is the same – also helps to put some big recent business developments into context.
ABSTRACT Massive multiple-input multiple-output antenna systems, millimeter wave communications, and ultra-dense networks have been widely perceived as the three key enablers that facilitate the development and deployment of 5G systems. This article discusses the intelligent agent that combines sensing, learning, and optimizing to facilitate these enablers. We present a flexible, rapidly deployable, and cross-layer artificial intelligence (AI)-based framework to enable the imminent and future demands on 5G and beyond. We present example AIenabled 5G use cases that accommodate important 5G-specific capabilities and discuss the value of AI for enabling network evolution. I. Introduction Does 5G cellular communications technology in the age of intelligence really look like the Thomas W. Lawson Schooner (the last of the large cargo sailing ships) of modern times? However, concerns are raised whether this is a revolutionary leap from today's wireless communications or a simple piling upof less innovative wireless functionalities. The International TelecommunicationUnion (ITU) classifies 5G into three categories of usage scenarios: enhanced mobile broadband (eMBB),massive machine-type communication (mMTC), and ultra-reliable and low latency communication (URLLC) to account for more diverse services and resourcehungry applications.eMBB is a service category that addresses bandwidth-hungryapplications, such as massive video streaming and virtual/augmented reality (VR/AR). URLLC is a service category that supports latency sensitive services including autonomous driving,drones and the tactile Internet.
In the gleaming but quiet headquarters of a startup called Starry--above the din of Boston's Downtown Crossing--40 engineers are toiling to achieve a disruptive vision: delivering Internet access to apartments and businesses, cheaply and wirelessly, nearly 100 times faster than the average home connection today. The idea of gigabit-per-second wireless service to homes has been around for at least 15 years, but technology advancements make the idea far more plausible today. The high-capacity wireless technology involved--known by a chunky piece of jargon, "millimeter wave active phased array"--is now much less expensive and bulky thanks to advances in microelectronics and software. Telecom giants including Verizon and AT&T are working on the technology, as are Facebook and Google with their efforts to provide fast public Wi-Fi access. Starry's service, expected to launch this summer, would be the first to use the technology to actually get inside homes and offices.
