Internet of Things: Introduction,ties and identified threats. Formal definitions are presented (e.g. according to ITU Y.2060) along with a proper nomenclature (that is often misused in current literature by mixing or confusing terms and acronyms as synonymous whereas they represent disparate entities), a reference IoT model, low- aFAWN 发表于 2025-3-25 22:00:20
IoT Networks Standardization and Legal Regulations,ocesses in IoT domain are also described with an emphasis on initiatives such as the IEEE P2413 standard or three ETSI documents regarding architectural and applications-related aspects of Low-Throughput Networks (ETSI GS LTN 001-003). One of the subchapters is devoted to spectral issues such as freFulminate 发表于 2025-3-26 01:06:39
Propagation Models for LTN Systems,ts (i.e. urban- and suburban macrocells, urban microcells, open areas, indoors of various types, vehicles). The chapter opens with the traditional Hata model and then moves on to the WINNER+ model and two 3GPP models: the simple one (for rough but quick estimates) and the extended one dealing in det不利 发表于 2025-3-26 05:50:25

The Internet of Things Narrow-Band LPWAN/UNB Systems,. Discussed aspects include topology, radio interfaces, classes of devices, transmission frame structure, most important commands and media access control mechanisms. The chapter can thus be regarded as an extension to the previous chapter in which the techniques for PHY and MAC layer represented caCAMEO 发表于 2025-3-26 16:20:15
Performance Measurements Methodology for LTN IoT Systems,rein they work, by providing facts regarding trends in the EM noise rise globally and known issues that this rise has caused in real IoT networks. Two major sources of EM risk have been identified: the EM interference and the multipath propagation. Since direct measurements of IoT systems with respenutrients 发表于 2025-3-26 17:09:57
