These include, but are not limited to automated meter reads, product break notifications, maintenance support, and process automation. A detailed review and comparison of the available wireless WANs currently in operation was conducted. Out of the numerous choices the best-suited protocol, based on a number of decision metrics, was chosen for the task at hand. Finally, the system was prototyped in hardware and in software using the Java™ programming language. Simulations using wired networks demonstrated the successful operation of the remote administration functions. iv Table of Contents Curriculum

  • FROM Cable Advisory Committee TO: Truro BOS and Town Administration January 2011 Municipal Area Network and Open Cape in Truro
    FROM Cable Advisory Committee TO: Truro BOS and Town Administration January 2011 Municipal Area Network and Open Cape in Truro: Background information, Definitions, Questions Introduction: This document was prepared by Mike Forgione of the Cable Committee to provide background to town officials and to begin to frame the issues as we prepare for Open Cape’s bringing additional high-speed Internet connections to Truro. Executive Summary During the past year we have heard about the technical terms of Municipal Area Network, I-nets, the Internet and World Wide Web. Along the way, we heard Comcast Broadband service and Open Cape. To make things worse, we heard about Dial-up Service, Digital Subscriber Lines (DSL), Cable Modem Internet, Satellite Internet, Broadband over Power Line, Wireless Networks and 3G/4G wireless. What are these things? Why and when do I need them? What do they do? Below is our attempt to address this very complex and technical topic. Our goal in this document is NOT to make a decision on what Truro needs. Our goals are: 1. To provide an understanding of Networks and the Internet. This understanding will assist us in our decision of a Municipal Area Network for Truro. 2. To begin the discussion of how we can effectively utilize Open Cape to lower the operation cost of Truro’s Information needs. Based on current plans, Open Cape will be fully deployed within the next 3 to 5 years. How will it change Truro? To help simplify these concepts, we will use the example of road system. The US road system, with its local roads, Intrastate highway and Interstate highway offer a good ―real-life‖ example of networks.

  • Wide Area Network
    Wide area network A wide area network (WAN) is a telecommunications network or computer network that extends over a large geographical distance. Wide area networks are often established with leased telecommunication circuits.[1] Business, education and government entities use wide area networks to relay data to staff, students, clients, buyers, and suppliers from various locations across the world. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet may be considered a WAN.[2] Related terms for other types of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area respectively. Contents Design options Connection technology List of WAN types See also References External links Design options The textbook definition of a WAN is a computer network spanning regions, countries, or even the world.[3] However, in terms of the application of computer networking protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other localised computer networking architectures. This distinction stems from the fact that common LAN technologies operating at lower layers of the OSI model (such as the forms of Ethernet or Wi-Fi) are often designed for physically proximal networks, and thus cannot transmit data over tens, hundreds or even thousands of miles or kilometres. WANs do not just necessarily connect physically disparate LANs. A CAN, for example, may have a localized backbone of a WAN technology, which connects different LANs within a campus.
