At the same time, the hallmarks of the previous editions, including the text's popular tutorial presentation, have been retained. Readers therefore get all the tools and guidance they need to master an essential set of current design techniques for radio systems that operate at frequencies of 3 MHz to 100 GHz. Using simple mathematics, the author illustrates design concepts and applications. The book's logical organization, beginning with a discussion of radio propagation problems, enables readers to progressively develop the skills and knowledge needed to advance in the text. Topics that are new to the Third Edition include: . Chapter devoted to wireless LANs (WLANs) as detailed in IEEE 802.11. Subsections covering IEEE 802.15, 802.16, 802.20, and the wireless metropolitan area network (WMAN). WiFi, WiMax, and UWB applications that have recently experienced explosive growth. Broadband radio in telecommunications, as well as offset frequency division multiplex (OFDM), a new technique for transmitting information in an interference environment. The use of very small aperture satellite terminal (VSAT) systems as an economical alternative to public switched telecommunication networks (PSTN) Review questions and problems at the end of each chapter engage readers' newfound skills and knowledge and help them assess whether they are ready to progress to the next chapter. References are provided for readers who want to investigate particular topics in greater depth. Students in wireless telecommunications will find the book's tutorial style ideal for learning all the ins and outs of radio system design, whereas professionals in the industry will want to refer to the Third Edition for its clear explanations of the latest technology and applications.Wiley series in telecommunications and signal processing ;98Radio relay systemsDesign and constructionRadio relay systemsDesign and construction.621.384621.384156Freeman Roger L464237CaBNVSLCaBNVSLCaBNVSLBOOK9910831085603321Radio system design for telecommunications229728UNINA03121nam 22006735 450 991076027570332120240702103701.09789819975662981997566210.1007/978-981-99-7566-2(MiAaPQ)EBC30853346(Au-PeEL)EBL30853346(DE-He213)978-981-99-7566-2(CKB)28652790900041(OCoLC)1407315353(EXLCZ)992865279090004120231101d2024 u| 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierCarbon-Based Electrodes for High-Performance Sodium-Ion Batteries and Their Interfacial Electrochemistry /by Jun Zhang1st ed. 2024.Singapore :Springer Nature Singapore :Imprint: Springer,2024.1 online resource (117 pages)Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061Print version: Zhang, Jun Carbon-Based Electrodes for High-Performance Sodium-Ion Batteries and Their Interfacial Electrochemistry Singapore : Springer Singapore Pte.

By proposing folded-graphene as the high-density cathode with excellent rate capability, it provides insight into the interplay between oxygen functional groups and folded texture. It also highlights the superiority of ether electrolytes matching with carbon anodes, which are shown to deliver largely improved electrochemical performance. The achievements presented offer a valuable contribution to the carbon-based electrodes in SIBs.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061Electric batteriesMaterialsElectrochemistryNanotechnologyMaterials scienceBatteriesElectrochemistryNanotechnologyMaterials ScienceElectric batteries.Materials.Electrochemistry.Nanotechnology.Materials science.Batteries.Electrochemistry.Nanotechnology.Materials Science.620.11621.31242Zhang Jun900220MiAaPQMiAaPQMiAaPQBOOK9910760275703321Carbon-Based Electrodes for High-Performance Sodium-Ion Batteries and Their Interfacial Electrochemistry3598706UNINA
