Book excerpt: Three major areas of activities in support of packet radio communications are reported in this document. These are: (1) Analysis of the pseudorandom code spread spectrum technique, (2) evaluation and selection of the pseudorandom codes for the experimental repeater, and (3) development of a signal capture model. The analysis of the code spread spectrum includes considerations of synchronization and multiple access capabilities. The code selection is based on the computer-derived side lobe properties and crosscorrelation of high data rate codes with low data rate codes. The developed capture model is based on the repeater design currently being developed and will be used to model capture in the existing packet radio network simulation models, which presently have no capture. Also, a brief status report of the repeater equipment development is included in the introduction. (Author).

Download or read book A Practical Terrestrial Packet Radio Network written by S. W Phillips (III.) and published by . This book was released on 1983 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A terrestrial packet radio network, now a competitive reality, offers a new alternative for local networks. Taking advantage of its adaptability to local environments and to the growing sources of digital communications, permits extension of data communications to remote locations. While adding capabilities for dispersed computer communications, there are limitations in using packet radio due to its bursty nature and less than absolute reliability. But as a message service for short duration communications, terrestrial packet radio may rapidly fill an important gap in communications. This thesis examines the features and design considerations for a practical terrestrial packet radio network. Packet radio equipment, evolving through stages of sophistication and new generation microcircuitry, is approaching the hand held model. While new digital features improve its mobility, the crucial consideration becomes the interconnection with other systems through adaptable protocols. This issue dominates the current research.

Download or read book Circuits Packets and Protocols written by James L. Pelkey and published by Morgan & Claypool. This book was released on 2022-04-19 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: As recently as 1968, computer scientists were uncertain how best to interconnect even two computers. The notion that within a few decades the challenge would be how to interconnect millions of computers around the globe was too far-fetched to contemplate. Yet, by 1988, that is precisely what was happening. The products and devices developed in the intervening years—such as modems, multiplexers, local area networks, and routers—became the linchpins of the global digital society. How did such revolutionary innovation occur? This book tells the story of the entrepreneurs who were able to harness and join two factors: the energy of computer science researchers supported by governments and universities, and the tremendous commercial demand for Internetworking computers. The centerpiece of this history comes from unpublished interviews from the late 1980s with over 80 computing industry pioneers, including Paul Baran, J.C.R. Licklider, Vint Cerf, Robert Kahn, Larry Roberts, and Robert Metcalfe. These individuals give us unique insights into the creation of multi-billion dollar markets for computer-communications equipment, and they reveal how entrepreneurs struggled with failure, uncertainty, and the limits of knowledge.

Download or read book Voice Communications Over Packet Radio Networks written by M. M. Seah and published by . This book was released on 1985 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of packet virtual circuit technique for voice communications in military radio networks was investigated. The work was concerned with various aspects of networking which include network modeling, communications techniques, traffic analysis and network control. An attempt has been made to develop a simple yet efficient time slot assignment algorithm was analyzed under a variety of slot depths and networks topologies using computer simulation. The Erlang' B results were used to provide more insight into the channel characteristics of the packet radio networks. The capabilities of implementing TDMA/CDMA hybrid schemes in the system were scrutinized. A method to estimate the transmission capacity of the inter-node links was found. We demonstrate its effectiveness in controlling local congestion by computer simulation. Graphical results were presented to highlight the behavior of the proposed packet radio networks. We concluded that an appropriate link weight function would provide efficient and reliable network services. Keywords include: Packet virtual circuit, Voice communications, Routing, Code division multiple access, Network modeling, and Link distance.
