The government said Tuesday it will draw up a comprehensive strategy by this summer on future 6G wireless communications networks and set up a panel to discuss the matter later this month. The panel on 6G ultrafast communications networks that are expected to be introduced around 2030, succeeding 5G services to be available in Japan this spring, will discuss technological development, potential utilization methods and policies, according to the Internal Affairs and Communications Ministry. "The smooth introduction of standards for next-generation wireless communications networks is indispensable to boosting Japan's international competitiveness," communications minister Sanae Takaichi said at a news conference. Japan has lagged behind the United States and South Korea in launching 5G commercial services. As some other countries have already started discussions on how to utilize 6G technology, Tokyo aims to draft the strategy and lead standardization efforts.
Due to the advancements in cellular technologies and the dense deployment of cellular infrastructure, integrating unmanned aerial vehicles (UAVs) into the fifth-generation (5G) and beyond cellular networks is a promising solution to achieve safe UAV operation as well as enabling diversified applications with mission-specific payload data delivery. In particular, 5G networks need to support three typical usage scenarios, namely, enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). On the one hand, UAVs can be leveraged as cost-effective aerial platforms to provide ground users with enhanced communication services by exploiting their high cruising altitude and controllable maneuverability in three-dimensional (3D) space. On the other hand, providing such communication services simultaneously for both UAV and ground users poses new challenges due to the need for ubiquitous 3D signal coverage as well as the strong air-ground network interference. Besides the requirement of high-performance wireless communications, the ability to support effective and efficient sensing as well as network intelligence is also essential for 5G-and-beyond 3D heterogeneous wireless networks with coexisting aerial and ground users. In this paper, we provide a comprehensive overview of the latest research efforts on integrating UAVs into cellular networks, with an emphasis on how to exploit advanced techniques (e.g., intelligent reflecting surface, short packet transmission, energy harvesting, joint communication and radar sensing, and edge intelligence) to meet the diversified service requirements of next-generation wireless systems. Moreover, we highlight important directions for further investigation in future work.
Wireless communication is ubiquitous in the enterprise, just as you'll find it everywhere else, from your home to the stores in your local mall, and even on many airlines and passenger trains. This wide availability makes it easy to use wireless, but it also means that the threats to your security are vast. Fortunately, it is possible to keep your communications secure and your devices safe, but it can take some planning and some work. Compounding the complexity of the wireless landscape, there are many types of wireless communications that your organization can be using. The most common are WiFi and cellular communications, but as we'll see, there are plenty of others.
Everyone is talking about 5G and industry is, above all, anticipating many benefits and future-oriented potential from the new mobile network standard. However, this development has not simply "dropped in industry's lap". In fact, the 2G to 4G mobile phone generations have already had a significant impact on industrial progress. For example, 2G enabled RTUs to send text messages and 3G provided remote access, e. g. for remote maintenance. The 3rd Generation Partnership Project (3GPP) which, amongst other things, is responsible for global standardization of mobile networks, created a vision for 5G which has three key scenarios.
