    Default Re: TETRA conference papers

    I post them as far as finding, among other documents that interest me, if you look closely, they are not posted out all in one day. But if there is such a need, in the end I'll post a general archive of publications on the topic, but I do not know when I finish work on this topic...

    Thumbs up Re: TETRA conference papers

    And the next interesting paper:

    Path Loss Model for TETRA Networks in Metropolitan Areas

    Abstract
    This paper reports on measurements of the
    attenuation in the transmitted RF'-power of a TETRA
    system, operating in the UHF band The
    measurements data are consistent with a log-distance
    path loss model for arbitrary T-R separation, with a
    path loss exponent n = 4.0 f 0.5. Small scale fading
    is characterized by a Gaussian signal level
    distribution (lognormal) with standard deviation U =
    8.6 f 0.2. Furthermore, the reference distance in the
    ,far ,field of the transmitting antenna from the
    measurements is do= I km. Interestingly, the average
    . value of the received UF-power approaches a level
    close to the dynamic sensitivity of the TETRA
    receivers at approximately the same distance (around
    5 km) from a base station, for various low-altitude
    base station locations with similar transmission
    characteristics. This distance provides a simple
    characterization reference indicative of the
    attenuation of the RF-power in the particular urban
    environment; it also provides a rule of thumb for cell
    planning in metropolitan locations similar to that of
    the Greek capital.

    A Statistical Traffic Analysis of Group Speech Communications in
    the German TETRA Trial Aachen


    Abstract

    In this paper. we present a novel model for group
    speech communications. This model includes timing
    parameters as well (U parameters fur spatial distribution
    and communications topology., parameters
    values for this model are derived from the German
    Terrestrial M e d Radio (TETRA) trial Aachen.
    In order to derive generalized parameters values,, we
    study statistical relationships between model parameters
    and other measured values. Finally, we apply
    the new traffic model to a queuing model of a TETRA
    system and study Quality of Service (QoS) aspects.

    TETRA (Terrestrial Trunked Radio) - Technical Features and Application
    of Professional. Communication Technologies in Mobile Digital Radio
    Networks for Special Purpose Services


    Abstract - TETRA Standard, within the European Telecommunication Standards Institute ETSI defines U digital mobile radio system for voice and data communication in Ultra High Frequency (UHF) band. 7he main function of the system is to provide service to Private Professional Mobile Radio (PMR) @pes of users. TETRA system offers a robust and professional mobile communication through cell @pe system deployments. traditional PMR telephony and digital data transmission. It is a highly reliable system suitable for use by different Qpes of mers that require their communication system to provide instant transmission, high reliability and availability with an additional set of services designed to accommodate the everyday. use of the system m well as provide unconditional support in extraordinary circumstances. This paper describes a technical solution for a TETRA network covering the Croatian coast and islundr, the Adriatic Sea and the protected Croatian ecological area in the Adriatic. n e technical solution is developed for the needs of interested government institutions, 1 I2 protection and rescue service, Automatic
    Identification System for traffic control in the Croatian national sea and other potential users.

    Professional Mobile system - TETRA over IP
    and IP over TETRA


    Abstract- Terrestrial Trunked Radio is a system used for
    professional mobile radio or public access mobile radio. TETRA
    is designed for different institutions: Dam, Telekom, airports,
    security organisations, etc. The system is applied for wireless
    technologies like IP over Tetra, Tetra over IP, and WAP. We
    dcsrribe this kind of system (IP/TETRA,TETRAnP,WAP). The
    most important point of the system is encryption data for
    different kind of users. We describe a system which already
    exists in Slovenia.

    Hi,

    Your efforts are highly appreciated AlexSSS.
    The proposal was meant to make it easier for members to get all documents at one shut.


    BR,

    DEVELOPMENT OF A TRAFFIC SIMULATOR FOR MOBILE COMMUNICATION
    NETWORKS BASED ON TETRA TECHNOLOGY

    Abstract - In this paper, we present a computer-tool to
    simulate traffic over a mobile communications network
    based on TETRA (Trans European Trunked RAdio)
    technology. This tool is specifically oriented to estimate
    network performances, previous to the network
    development, in order to make an optimum network design.
