whitepaper Recent Progress and Standardization of Terrestrial Wireless and Satellite Communication Systems2009-03-04
  This paper overviews the recent progress and standardization of terrestrial wireless and satellite communication systems. The terrestrial wireless systems are now standardized by ITU-R SG5 in the area of IMT-2000, IMT-Advanced, land mobile systems, aeronautical mobile systems and fixed wireless access systems. This paper focuses on the free-space optical communication systems which can transmit a very high-speed data and describes their characteristics which are discussed within not only ITU-R WP5C but also international conferences. The inter-orbit optical communication systems which utilize the advantages of optical transmission features as a high capacity transmission link are also introduced. Finally, the new architectures for both fixed and mobile satellite communication systems are discussed within ITU-R WP4B.

whitepaper CSC Supports Groundbreaking Satellite Mission2009-01-26 Computer Sciences
  Following decades of work on major NASA efforts such as the Apollo program, they're playing a key role in the success of a small and relatively inexpensive next-generation satellite. The company wanted to work with the Naval Academy to design, build and launch a low-cost satellite that serves as a flexible platform for scientific experiments. The company deployed a Linux-based operating system and communications based on Internet protocols to construct a no-frills satellite. The MidSTAR-1 satellite has hosted several successful experiments, including the first application of nanotechnology in space.

whitepaper Operating XMPP Over Radio and Satellite Networks2009-01-07 Isode
  XMPP, the Internet Standard eXtensible Messaging and Presence Protocol is being widely adopted for Instant Messaging (IM), Group Chat and Presence services in military networks. This paper starts by looking at the military tactical requirements for IM, Group Chat and Presence. It discusses briefly why XMPP is ideal for these services, and also as a building block for situational awareness systems and in support of voice and video communication. Tactical networks often need to make use of Radio and Satellite networks with constrained bandwidth, high latency and difficult operational characteristics. This paper looks at the problems of deploying XMPP over such networks, and shows how XMPP can be effectively deployed in such environments.

whitepaper GPS/GPRS/GSM Based Mobile Asset Tracking2009-01-01 Calsoft Labs
  Global Positioning Satellites (GPS) enable the tracking of all kinds of mobile assets accurately and provide their real time positions to the owners on a 24 by 7 basis over the GPRS/GSM link. While the GPS provides the latitude/longitude information of the mobile asset a given time, this information can be transmitted to any place using the GPRS radio link. In fact, the asset can even have enough intelligence built into it to initiate calls using the GSM phone links. The technology and the cost of implementing this technology has come down drastically over the last few years making them very affordable to the general public.

whitepaper Troubleshoot Network Time Protocol2008-11-05 Cisco Systems
  This paper provides information on how to troubleshoot common problems with Network Time Protocol (NTP). Network Time Protocol (NTP) is widely used in order to synchronize a computer to Internet time servers or other sources, such as a radio or satellite receivers or telephone modem services. It provides accuracies typically less than a millisecond on LANs and up to a few milliseconds on WANs. Typical NTP configurations utilize multiple redundant servers and diverse network paths in order to achieve high accuracy and reliability.

whitepaper On-Site Video Production2008-09-12
  High-profile meeting events demand high-quality presentation. With geographically dispersed audiences, schedules that are nearly impossible to sync, and ever-increasing costs of travel, how do users engage their audience in a visually dynamic presentation and provides face-to-face results? InterCall's on-site video production services have a powerful impact on the audience through the use of videoconferencing, internet broadcasting and satellite communications.

whitepaper Linweld Takes Office on the Road With Global Broadband Satellite Access2008-07-01
  Linweld manufactures and distributes medical, specialty, and industrial gases and welding supplies, as well as clean air products. The company maintains store locations in the Midwest United States. To actively market its products and services throughout its territory, Linweld visits trade shows and maintains a field sales force. But doing business at all locations is not always easy, because Linweld's territory includes many remote areas. That's never stopped the company, but it can slow it down. Verizon Business's Global Broadband Satellite Access answered Linweld's business needs. The solution provides high-speed Internet access virtually anywhere, enabling employees to communicate effectively while at remote locations via voice and data.

whitepaper Key Application - Shared Outbound (Point-to-Multipoint): Using the Vocality Multiplexer/Router Over Point-to-Multipoint Networks Efficiently Using Large Outbound/Small Inbound Architecture2008-06-12 Vocality International
  This white paper provides an overview of a system configuration achievable through a combination of hardware from Vocality and traditional SCPC satellite modems. Satellite users such as welfare deployments or Satellite News Gathering truck operators will see immediate benefit from the flexible nature of the system design, allowing easy to configure voice, data and clean feed audio to be transmitted to or from remote to the central hub site - with a migration path which will allow MPEG 4 video to be transmitted over IP alongside the communications router services.

whitepaper Enabling IPTV: What's Needed in the Access Network2008-04-14 Alcatel-Lucent
  Service providers around the globe have begun commercializing triple play services to better compete with cable and satellite operators. While this is helping boost Average Revenue Per User (ARPU), it is placing unprecedented stress on the traditional high-speed Internet infrastructure. This paper examines the issues of deploying triple play services - and, more specifically, the unique demands of Internet Protocol Television (IPTV) service delivery. It illuminates the need for a transformation of the access network architecture toward Ethernet and IP technology for a solution that can bring together access, aggregation, edge and subscriber service delivery while addressing cost, reliability, scalability and Quality of Service (QoS) requirements.

whitepaper Making the Grade: Mission Critical Radios Give University Police the Dependable Communications Needed for a Safer Campus2008-03-01 Motorola
  ASU has four campuses. There are currently 65,000 students and there are plans to expand to 90 or 95,000 students in the next 10 to 15 years. ASU had a VHF conventional system originally designed for one campus. It had components that were 20-25 years old. The department started looking at replacing the old system about five years ago. They were looking for greater reliability and greater coverage in the buildings. It was also apparent that the department needed greater interoperability with the surrounding agencies. The turning point was Virginia Tech.
