A Study on Wireless Technologies to Improve Communication Performance by Utilizing Multifrequency Bands

摘要

The wireless access network for the Internet of Things must offer ultra-broadband communication in order to transfer broadband data such as video data to be displayed for user assistance. High-reliability and low-latency communication is also necessary to remotely and automatically control the instruments of vehicles and robots in real time. This article describes our study on wireless technologies designed to achieve ultra-broadband, high-reliability, and lowlatency communications by utilizing new frequency bands.
