دانلود کتاب دسترسی عظیم IoT با تکنولوژی 6G

The IoT is playing a major role across a variety of vertical sectors by generating tremendous cost savings and new revenue streams. With the advent of the IoT era, the ever-increasing number of machine-type devices and the emerging applications have triggered the need for affordable, ubiquitous, and massive IoT connectivity. In fact, various industry leading companies, such as Samsung and Ericsson, have predicted that the number of connected devices will reach 500 billion by 2030, which is about 59 times larger than the expected world population by that time. Against this background, massive IoT access, also known as massive connectivity or massive machine-type communication (mMTC), has been proposed as a key enabler for IoT applications in the next-generation wireless networks, i.e., sixth-generation mobile network (6G). Different from conventional human-type communications, massive IoT access aims at realizing efficient and reliable communications for an extremely large number of IoT devices. The distinct characteristics of massive IoT access include low power, massive connectivity, broad coverage, and sporadic uplink traffic, which require new concepts, theories, and paradigms for designing the next-generation cellular networks.
