Location, location-awareness, and location data have all become familiar and increasingly significant parts of our everyday mobile-mediated experiences. Cultural Economies of Locative Media examines the ways in which location-based services, such as GPS-enabled mobile smartphones, are socially, culturally, economically, and politically produced just as much as they are technically designed and manufactured. Rowan Wilken explores the complex interrelationships that mutually define new business models and the economic factors that emerge around, and structure, locative media services. Further, he offers readers insight into the diverse social uses, cultures of consumption, and policy implications of location, providing a detailed, critical account of contemporary location-sensitive mobile data. Cultural Economies of Locative Media delves into the ideas, technologies, contexts, and power relationships that define this scholarship, resulting in a rich portrait of locative media in all of its cultural and economic complexity.

Unleash the power of declarative programming in SwiftUI by building cross-platform Apple apps for iOS 15, macOS, and watchOS using Swift 5.5, Xcode 13, and SwiftUI 3 Key Features Apply the declarative programming paradigm to build cross-platform UIs for Apple devices Learn to integrate UIkit, Core Data, Firebase, and Sign in with Apple with SwiftUI Adopt the new SwiftUI 3.0 features to build visually appealing UIs speedily Book DescriptionSwiftUI provides an innovative and simple way to build beautiful user interfaces (UIs) for all Apple platforms, from iOS and macOS through to watchOS and tvOS, using the Swift programming language. In this recipe-based cookbook, you'll cover the foundations of SwiftUI as well as the new SwiftUI 3 features introduced in iOS 15 and explore a range of essential techniques and concepts that will help you through the development process. The cookbook begins by explaining how to use basic SwiftUI components. Once you've learned the core concepts of UI development, such as Views, Controls, Lists, and ScrollViews, using practical implementations in Swift, you'll advance to adding useful features to SwiftUI using drawings, built-in shapes, animations, and transitions. You'll understand how to integrate SwiftUI with exciting new components in the Apple development ecosystem, such as Combine for managing events and Core Data for managing app data. Finally, you'll write iOS, macOS, and watchOS apps by sharing the same SwiftUI codebase. By the end of this SwiftUI book, you'll have discovered a range of simple, direct solutions to common problems encountered when building SwiftUI apps. What you will learn Explore various layout presentations in SwiftUI such as HStack, VStack, LazyHStack, and LazyVGrid Create widgets to quickly display relevant content at glance Get up to speed with drawings in SwiftUI using built-in shapes, custom paths, and polygons Discover modern animation and transition techniques in SwiftUI Add user authentication using Firebase and Sign in with Apple Manage concurrency with Combine and async/await in SwiftUI Solve the most common SwiftUI problems, such as integrating a MapKit map, unit testing, snapshot testing, and previewing layouts Who this book is forThis book is for mobile developers who want to learn SwiftUI as well as experienced iOS developers transitioning from UIkit to SwiftUI. The book assumes knowledge of the Swift programming language. Knowledge of object-oriented design and data structures will be useful but not necessary. You'll also find this book to be a helpful resource if you're looking for reference material regarding the implementation of various features in SwiftUI.

Written by the pioneers of Flash-OFDM, arguably the first commercially developed OFDMA-based mobile broadband system in the world, this book teaches OFDMA from first principles, enabling readers to understand mobile broadband as a whole. The book examines the key requirements for data-centric mobile; how OFDMA fits well with data networks; why mobile broadband needs to be IP-based; and how to bridge communications theory to real-world air interface design and make a good system choice between performance and complexity. It also explores the future of wireless technologies beyond conventional cellular architecture. One of the key challenges faced by newcomers to this field is how to apply the wireless communications theory and principles to the real world and how to understand sophisticated commercial systems such as LTE. The authors use their firsthand experience to help graduate students, researchers and professionals working on 4G to bridge the gap between theory and practice.

The cheap mobile phone is arguably the most significant personal communications device in history. In India, where caste hierarchy has reinforced power for generations, the disruptive potential of the mobile phone is even more striking than elsewhere. In 2001, India had 35 million telephones, only four million of them mobiles. Ten years later, it had more than 800 million phone subscribers; more than 95 per cent were mobile phones. In a decade, communications in India have been transformed by a device that can be shared by fisherfolk in Kerala, boatmen in Banaras, great capitalists in Mumbai and power-wielding politicians and bureaucrats in New Delhi. Village councils banned unmarried girls from having mobile phones. Families debated whether new brides should surrender them. Cheap mobile phones became photo albums, music machines and radios. Religious images and uplifting messages flooded tens of millions of phones each day. Pornographers and criminals found a tantalising new tool. In politics, organisations with cadres of true believers exploited a resource infinitely more effective than telegrams, postcards and the printing press for carrying messages to workers, followers and voters. Jeffrey and Doron focus on three groups - controllers: the bureaucrats, politicians and capitalists who wrestle over control of radio frequency spectrum; servants: the marketers, agents, technicians, tower-builders, repairers and second-hand dealers who carry mobile phones to the masses; and users: the politicians, activists, businesses and households that adapt the mobile phone to their needs. The book probes the whole universe of the mobile phone - from the contests of great capitalists and governments to control radio frequency spectrum, to the ways ordinary people build the troublesome and addictive device into their daily lives.
