A systematic review of WLL systems Wireless local loop (WLL) systems present an economically viable technology for providing telecommunications services to subscribers in both sparsely populated and highly congested areas. However, successfully managing a WLL system from initial concept to final implementation requires that engineers and technical managers consider a wide range of technical and strategic planning variables. Introduction to WLLs: Application and Deployment for Fixed and Broadband Services provides a systems-level view of the technical, planning, and deployment aspects of WLL systems. It covers these systems as an alternative to both copper-based access for narrowband services (voice and voice-band data) and copper-, fiber-, or cable-based access for broadband services (video on demand, Internet access, high-speed data). Individual chapter topics include: Introduction to WLL systems Fundamentals of radio systems Key cellular and cordless technologies WLL systems designsystem components and interfaces WLL systems designradio aspects Planning and deployment of WLL systems Examples of commercially available WLL systems Broadband applications and services.
