Fast asymmetric Internet over wireless satellite-terrestrial networks

2021

IAPGOS

Satellites are the transmission medium for providing connectivity and building global, continental, or regional networks around the world (satellite operators effectively use satellites to support Internet traffic), and point-to-point connections are also possible. In practical use, there are combinations of VSAT networks with terrestrial wireless extensions, allowing end users to increase the capabilities offered via satellite. This paper provides selected information on broadband satellite networks using VSAT technology, including available protocols and transmission platforms. The aim of the article is also to present the chosen technical aspects of satellite networks working with the usage of VSAT technology.

“…J.S. Baras, S. Corson, S. Papadememou, I. Secka, and N. Suphasindhu similarly indicate that there are two main obstacles (bottlenecks) in achieving the assumed transmission rate [3]. The mechanism of controlling the ow of the TCP protocol from end to end depends on the size of the window and time of the return trip.…”

A review on information systems engineering using vsat networks and their development directions

2021

Yugosl J Oper Rres

Modern satellite VSAT networks can be applied not only to provide satellite radio and television broadcasting, but also to other domains, such as a two-way Internet access. For this objective it has become necessary to develop appropriate standards and data transmission techniques. An unquestionable advantage of satellite systems is reception range, which translates into possibility of building networks in almost any place on Earth. Depending on the application, such networks can use many topologies. The aim of the article is to review distributed information in this area, as well as to determine the directions of development of the next generation VSAT networks. For this purpose, the literature review has been provided, with due regard to the IEEE Xplore digital library databases, and supported by practical examples.

“…It is possible to use retransmission satellites for the access network. Wired or radio links can be used to build a return channel, and the satellite part as a receiver [1]. When a terminal allowing both reception and data transmission is used, then the terrestrial technical infrastructure is not included [30].…”

Overview of Broadband Information Systems Architecture for Crisis Management

2020

IAPGOS

Many risks as a result of accidents, catastrophes and natural disasters can contribute to crisis situation, which according to the definition means a set of circumstances, both external and internal, that affect a given system through changes. Crisis situations are usually the result of natural disasters. Where such phenomena occur, it is important to ensure communication both at regional and national level. This is particularly important in areas affected by disasters caused by force majeure, such as earthquakes. The main aim of the article is to provide an overview of the architecture of contemporary information systems including satellite links, in order to present information on the potential possibilities of their use in the case of crisis situations.
