Low power wide area network (LPWAN) is a promising solution for long range and low power Internet of Things (IoT) and machine to machine (M2M) communication applications. The LPWANs are resource-constrained networks and have critical requirements for long battery life, extended coverage, high scalability, and low device and deployment costs. There are several design and deployment challenges such as media access control, spectrum management, link optimization and adaptability, energy harvesting, duty cycle restrictions, coexistence and interference, interoperability and heterogeneity, security and privacy, and others.LPWAN Technologies for IoT and M2M Applications is intended to provide a one-stop solution for study of LPWAN technologies as it covers a broad range of topics and multidisciplinary aspects of LPWAN and IoT. Primarily, the book focuses on design requirements and constraints, channel access, spectrum management, coexistence and interference issues, energy efficiency, technology candidates, use cases of different applications in smart city, healthcare, and transportation systems, security issues, hardware/software platforms, challenges, and future directions.

From the vital voice of Elijah Anderson, Black in White Space sheds fresh light on the dire persistence of racial discrimination in our country. A birder strolling in Central Park. A college student lounging on a university quad. Two men sitting in a coffee shop. Perfectly ordinary actions in ordinary settings—and yet, they sparked jarring and inflammatory responses that involved the police and attracted national media coverage. Why? In essence, Elijah Anderson would argue, because these were Black people existing in white spaces. In Black in White Space, Anderson brings his immense knowledge and ethnography to bear in this timely study of the racial barriers that are still firmly entrenched in our society at every class level. He focuses in on symbolic racism, a new form of racism in America caused by the stubbornly powerful stereotype of the ghetto embedded in the white imagination, which subconsciously connects all Black people with crime and poverty regardless of their social or economic position. White people typically avoid Black space, but Black people are required to navigate the “white space” as a condition of their existence. From Philadelphia street-corner conversations to Anderson’s own morning jogs through a Cape Cod vacation town, he probes a wealth of experiences to shed new light on how symbolic racism makes all Black people uniquely vulnerable to implicit bias in police stops and racial discrimination in our country. An unwavering truthteller in our national conversation on race, Anderson has shared intimate and sharp insights into Black life for decades. Vital and eye-opening, Black in White Space will be a must-read for anyone hoping to understand the lived realities of Black people and the structural underpinnings of racism in America.

Combines the latest trends in spectrum sharing, both from a research and a standards/regulation/experimental standpoint Written by noted professionals from academia, industry, and research labs, this unique book provides a comprehensive treatment of the principles and architectures for spectrum sharing in order to help with the existing and future spectrum crunch issues. It presents readers with the most current standardization trends, including CEPT / CEE, eLSA, CBRS, MulteFire, LTE-Unlicensed (LTE-U), LTE WLAN integration with Internet Protocol security tunnel (LWIP), and LTE/Wi-Fi aggregation (LWA), and offers substantial trials and experimental results, as well as system-level performance evaluation results. The book also includes a chapter focusing on spectrum policy reinforcement and another on the economics of spectrum sharing. Beginning with the historic form of cognitive radio, Spectrum Sharing: The Next Frontier in Wireless Networks continues with current standardized forms of spectrum sharing, and reviews all of the technical ingredients that may arise in spectrum sharing approaches. It also looks at policy and implementation aspects and ponders the future of the field. White spaces and data base-assisted spectrum sharing are discussed, as well as the licensed shared access approach and cooperative communication techniques. The book also covers reciprocity-based beam forming techniques for spectrum sharing in MIMO networks; resource allocation for shared spectrum networks; large scale wireless spectrum monitoring; and much more.

A 2021 C. Wright Mills Award Finalist Shows how government created “ghettos” and affluent white space and entrenched a system of American residential caste that is the linchpin of US inequality—and issues a call for abolition. The iconic Black hood, like slavery and Jim Crow, is a peculiar American institution animated by the ideology of white supremacy. Politicians and people of all colors propagated “ghetto” myths to justify racist policies that concentrated poverty in the hood and created high-opportunity white spaces. In White Space, Black Hood, Sheryll Cashin traces the history of anti-Black residential caste—boundary maintenance, opportunity hoarding, and stereotype-driven surveillance—and unpacks its current legacy so we can begin the work to dismantle the structures and policies that undermine Black lives. Drawing on nearly 2 decades of research in cities including Baltimore, St. Louis, Chicago, New York, and Cleveland, Cashin traces the processes of residential caste as it relates to housing, policing, schools, and transportation. She contends that geography is now central to American caste. Poverty-free havens and poverty-dense hoods would not exist if the state had not designed, constructed, and maintained this physical racial order. Cashin calls for abolition of these state-sanctioned processes. The ultimate goal is to change the lens through which society sees residents of poor Black neighborhoods from presumed thug to presumed citizen, and to transform the relationship of the state with these neighborhoods from punitive to caring. She calls for investment in a new infrastructure of opportunity in poor Black neighborhoods, including richly resourced schools and neighborhood centers, public transit, Peacemaker Fellowships, universal basic incomes, housing choice vouchers for residents, and mandatory inclusive housing elsewhere. Deeply researched and sharply written, White Space, Black Hood is a call to action for repairing what white supremacy still breaks. Includes historical photos, maps, and charts that illuminate the history of residential segregation as an institution and a tactic of racial oppression.
