Abstract:

The article discusses the development of an instrument complex (bench, stand) for the study of digital radio communication standards: APCO P25, DMR and TETRA, based on software-defined radio systems (SDR) technologies in voice mode. The bench is based on the HackRF One broadband SDR transceiver and the GNU Radio open software toolkit. Along with the SDR transceiver HackRF One, it is proposed to use the SDR TV tuner AstroMeta Digital TV Dongle as an available receiver. The structure of the hardware and software parts of the bench is proposed. The software implementation of listed digital radio

The Deep Astrometric Standards (DAS) program is designed to establish such a frame, by providing absolute astrometry at the 5–10 mas level in four 10 deg2 Galactic fields, to a depth of V=25. The source of our basic reference frame is the UCAC2 catalog, significantly improved by additional observations, and new VLBI positions of radio-loud and optically visible QSOs.

The transfer and deployment of GSM‐R is technically importance to the success of another European

Abstract:

Providing an available wideband and better antenna beam forming are two good profits of millimeter wave (mmWave) technology. MmWave technology makes radio systems lighter and smaller and radars more precise. Today, commercial MmWave equipment work below 90GHz frequencies. MmWave radios work to transport Internat traffic in the backhaul of communication networks. There is a challenge in mmWave technology since the prices of equipment increases as the frequency increases. In this paper we study the applications of mmWave technology, its products, standards and compare it with other wireless tech

Abstract:

While the discovery of the ionosphere through wireless communications technology in the mid-1920s had built a close connection between atmospheric science and radio, the full-fledged use of radio waves as a geophysical probe did not start until an instrumental development occurred a few years later. This article examines this advance, which centered on the invention of radio sounders of the ionosphere. Like the earlier radio experiments on the ionosphere, the sounders bounced radio waves off the upper atmosphere and inferred its properties from the returns. But the new apparatuses contained va

Abstract:

Many potentials exist in the 5G era for effectively managing vehicle safety on the road. The European Telecommunications Standards Institute (ETSI) 5G C-V2X standards for Cooperative Aware Messages for Intelligent Transport Systems (ITS) provide necessary upper-layer requirements for safety message distribution between vehicles using Cooperative Aware Messages (CAM). In addition, the Long Term Evolution (LTE) mobile radio technology in Release-14 has two modes of communication, mode 3 and mode 4, to facilitate vehicle-to-vehicle communications. The focus of this study is on vehicle communicati

Abstract In the paper modern concepts of radio communication trunking-dispatch systems for special applications are presented. Basic standards of TETRA, DMR, and cdma2000 are mentioned. The aim of the paper is to present innovative trunking solutions based on the LTE system working both in FDD and TDD mode. The architecture of LTE trunked radio is shown as well as new services possible to implementation are described. The way of TETRA and LTE integration is characterized.

Abstract:

A multi-tier radio access network (RAN) combining the strength of fibre-optic and radio access technologies employing adaptive microwave photonics interfaces and radio-over-fibre (RoF) techniques is envisioned for future heterogeneous wireless communications. All-band radio spectrum from 0.1 to 100 GHz will be used to deliver wireless services with high capacity, high link speed and low latency. The multi-tier RAN will improve the cell-edge performance in an integrated heterogeneous environment enabled by fibre–wireless integration and networking for mobile fronthaul/backhaul, resource sharing
