  • Evaluating Lora Physical As a Radio Link Technology for Use in a Remote-Controlled Electric Switch System for a Network Bridge
    Evaluating LoRa Physical as a Radio Link Technology for use in a Remote-Controlled Electric Switch System for a Network Bridge Radio-Node Abdullahi Aden Hassan / Rasmus Karlsson Källqvist KTH ROYAL INSTITUTE OF TECHNOLOGY ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Acknowledgments We would like to thank our academic mentor Anders Västberg for helping us with the process of writing and carrying through this degree project, answering all of our questions, and for proof reading this report. We would like to thank Amin Azari for showing genuine interest in our project and for answering some math questions we had when calculating the radio link budget, and for discovering that the formula in a book we were using had a printing error which was initially causing our results to be wrong. Thank you to fellow students Michael Henriksson and Sebastian Kullengren for a thorough opposition to this report and for much helpful feedback in keeping the text readable and scientific. Thank you to Björn Pehrson for representing AMPRNet Sweden and giving us the opportunity to work on this project, financing the system prototype and for giving helpful feedback. Finally, we would like to thank program director Bengt Molin for teaching us much of what we know of embedded systems and for lending us equipment used in the development of the hardware prototype. i Abstract This report explores the design of a system for remotely switching electronics on and off within a range of at least 15 km, to be used with battery driven radio nodes for outdoor Wi-Fi network bridging. The application of the network bridges are connecting to remote networks, should Internet infrastructure fail during an emergency.

  • New Gateways (PDF
    Packet Network Notice Rev: 28-Nov-2011 Date: Nov 28, 2011 From: Santa Clara County ARES/RACES Packet Committee Subject: Packet Network Update – New AMPRnet and E-mail gateways Attention: All ECs, AECs, MACs and other Santa Clara County Packet Users This Packet Network Notice contains important information which affects your ability to access and use the county packet backbone. This update covers the following topics: • New AMPRnet Gateway • New E-mail Gateway Please read this information thoroughly and pass along to any packet users in your local area. New AMPRnet Gateway The AMPRnet is an AMateur Packet Radio network consisting of packet radio BBSs located worldwide. Local networks of BBSs are interconnected to other local networks through gateways. These gateways use IP-in-IP tunnels to connect to each other. AMPRnet IP addresses are allocated from the IP address block of 44.0.0.0/8. Once a BBS or local network of BBSs is connected to AMPRnet, each of the BBSs can reach any other BBS on the AMPRnet, and vice-versa. For example, in the State of Michigan, each county has a local network of one or more BBSs. Each county is connected to all other counties (and to the rest of the world) with AMPRnet connections. Here in California, we can use AMPRnet connections to reach other counties which do not have a radio path to our network. We have just started to reach out to other counties to work on making those connections. There are two primary uses for this connectivity: 1) Messaging: Messages can now be addressed to anyone at any of the AMPRnet BBSs with a simple and standard Internet-style address format: [email protected].

    Integration of APRS Network with SDI Tomasz Kubik1,2, Wojciech Penar1 1 Wroclaw University of Technology 2 Wroclaw University of Environmental and Life Sciences Abstract. From the point of view of large information systems designers the most important thing is a certain abstraction enabling integration of heterogeneous solutions. Abstraction is associated with the standardization of protocols and interfaces of appropriate services. Behind this façade any device or sensor system may be hidden, even humans recording their measurements. This study presents selected topics and details related to two families of standards developed by OGC: OpenLS and SWE. It also dis- cusses the technical details of a solution built to intercept radio messages broadcast in the APRS network with telemetric information and weather conditions as payload. The basic assumptions and objectives of a prototype system that integrates elements of the APRS network and SWE are given. Keywords: SWE, OpenLS, APRS, SDI, web services 1. Introduction Modern measuring devices are no longer seen as tools for qualitative and quantitative measurements only. They have become parts of highly special- ized solutions, used for data acquisition and post-processing, offering hardware and software interfaces for communication. In the construction of these solutions the latest technologies from various fields are employed, including optics, precision mechanics, satellite and information technolo- gies. Thanks to the Internet and mobile technologies, several architectural and communication barriers caused by the wiring and placement of the sensors have been broken. Only recently the LBS (Location-Based Services) entered the field of IT. These are information services, available from mo- bile devices via mobile networks, giving possibility of utilization of a mobile This work was supported in part by the Polish Ministry of Science and Higher Edu- cation with funds for research for the years 2010-2013.

Telecomunicaciones Juan Francisco Redondo Ant´on Ad Hoc Networks – design and performance issues Thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Telecommunications Engineering Espoo, May 2002 Supervisor: Professor Jorma Virtamo Abstract of Master’s Thesis Author: Juan Francisco Redondo Ant´on Thesis Title: Ad hoc networks – design and performance issues Date: May the 28th, 2002 Number of pages: 121 Faculty: Helsinki University of Technology Department: Department of Electrical and Communications Engineering Professorship: S.38 – Networking Laboratory Supervisor: Professor Jorma Virtamo The fast development wireless networks have been experiencing recently offers a set of different possibilities for mobile users, that are bringing us closer to voice and data communications “anytime and anywhere”. Some outstanding solutions in this field are Wireless Local Area Networks, that offer high-speed data rate in small areas, and Wireless Wide Area Networks, that allow a greater mobility for users. In some situations, like in military environment and emergency and rescue operations, the necessity of establishing dynamic communications with no reliance on any kind of infrastructure is essential. Then, the ease of quick deployment ad hoc networks provide becomes of great usefulness. Ad hoc networks are formed by mobile hosts that cooperate with each other in a distributed way for the transmissions of packets over wireless links, their routing, and to manage the network itself. Their features condition their design in several network layers, so that parameters like bandwidth or energy consumption, that appear critical in a multi-layer design, must be carefully taken into account.

    Packet Radio Murray Amateur Radio Club (MARC) Jan L. Peterson (KD7ZWV) What is it? u Packet Radio is a digital communications mode where data is sent in ”packets.” u So what are packets? u Packets are discrete collections of data, typically called “datagrams”, that have assorted headers and trailers added to handle things like addressing, routing, and data integrity. u I’ve never heard of such a thing? u Sure you have... you’re using it right now. The Internet uses packet technology, and if you are using Wi-Fi, you are already using a form of packet radio! History u Radio is essentially a broadcast medium... many or all nodes are connected to the same network. u In the early 1970s, Norman Abramson of the University of Hawaii developed the ALOHAnet protocol to enable sharing of this medium. u Work done on ALOHAnet was instrumental in the development of Ethernet in the mid-to-late 1970s, including the choice of the CSMA mechanism for sharing the channel. u In the mid-1970s, DARPA created a system called PRNET in the bay area to experiment with ARPANET protocols over packet radio. History u In 1978, amateurs in Canada started experimenting with transmitting ASCII data over VHF using home-built hardware. u In 1980, the Vancouver Area Digital Communications Group started producing commercial hardware to facilitate this... these were the first Terminal Node Controllers (TNCs). u The FCC then authorized US amateurs to send digital ASCII data over VHF, also in 1980, including the facility for “digipeaters” or digital repeaters. u This started rolling out in San Francisco in late 1980 with a system called AMPRNet.
