o que o BRANDMEISTER !!!!

  Brandmeister ISRAEL !!!!

 

What is BrandMeister?


BrandMaster/BrandMeister is an operating software for master servers participating in a worldwide infrastructure network of amateur radio digital voice systems.
  • If you are an amateur radio operator working in digital voice modes like D-Star, DMR, C4FM, APCO25 or others (not all are supported yet!!). You do not need to know much about BrandMeister, and it's very easy to operate on its infrastructure.
  • If you are an amateur radio operator that runs a repeater in your local area, you may be interested in learning some more about BrandMeister and how you can take part in it.

A brief overview of BrandMeister core features:

  • Switching system for IP-enabled conventional Tier-2 DMR radio
  • Supports the most known network-access and end-user equipment making it easily expandable
  • Performs switching on the Layer 3 (Call Control) of the DMR stack
  • Has an embedded data stack (Layer 4)
  • Has embedded data and voice applications
  • Flexible routing based on data stored in a global database, local memory cache, and Lua scripts
  • Event notification using messaging queues (calls, connections, alarms, messages, locations and telemetry)
  • Allows one to build their own network based on mesh technology

BrandMeister allows you to connect to MOTOROLA DMR-MARC and Hytera DMRplus networks, this means you can operate with other DMR amateur radio operators on both infrastructures the same time.

BrandMeister allows me…

  • To roam automatically from repeater to repeater
  • To make private QSOs on any time-slot
  • To make world-wide QSOs with any type of amateur DMR network
  • To send my location to APRS
  • To send and receive SMS messages
  • To send and receive SMS messages to or from APRS
  • To control some electric thing using my DMR radio as a remote control device

Embedded Applications

  • Common-use applications:
    • Interactive voice response for status messages (with support for 5 languages),
    • Signaling expansion (UU-Req/UU-Resp)
    • Automatic registration/roaming (Hytera RRS)
    • Auto-patch call gateway
    • SMS gateway (vendor independent, supporting ETSI/Hytera/Motorola)
    • IP bridge


  • Examples of some Amateur Radio usage applications:
    • D-STAR D-Extra to talking group gateway
    • D-STAR G2 call routing to private call gateway
    • APRS position and telemetry reporting
    • APRS text message gateway
    • AMPR access service
    • Gateway for EchoLink or any other IP-based PTT applications

Architectural principles


The general architecture of BrandMeister consists of three different layers:
  • the first layer provides drivers for frontend/radio interfaces like Hytera Repeaters, Motorola repeaters, UP4DAR, homebrew repeaters
  • the second layer is built by the logical kernel with an implemented routing mechanism
  • the third layer consists of interfaces supporting communication service protocols to the WAN (IPSC, CC-Link, APRS, XRF)

All BrandMeister Master servers communicate with each other through the BrandMeister FastForward (FF) high-speed protocol.

  • BrandMeister is only a front-end application that works in real-time
  • All business logic to distribute routing lists and user profiles implemented outside of BrandMeister like a set of back-end applications and scripts
  • BrandMeister supports multiple sources of routing information: scripts, databases, in-memory cache, configuration files at the same time
  • Web applications and diagnostic tools are also separated out from the main program
  • BrandMeister uses event-driven mechanisms (MQ) to notify backends about events, in-memory data storage and relational database to get location, routing and user profiles

We are in the process of implementing mesh-based distributed network storage which will allow all network servers will be equivalent nodes.
This is a prerequisite to maintain high availability of the network and will help keep the infrastructure more resistant to temporary or permanent loss of single nodes.

BEER FEST NOVA LIMA MG 11 de março de 2017


TYTERA MD 380 UHF 



Ja estou ativo no DMR  com o radio da TEYTERA MD 380  em UHF e o dv4mini
ja fiz contatos no refletor Brasil com varios colegas e brasileiros Americanos e com a Alemanha

O que é DMR !!!!

É um padrão para comunicações de voz digital publicado pelo Instituto Europeu de Normas de Telecomunicações (ETSI) e que ao contrário de todos os outros, permite 2 conversas de voz simultâneas utilizando um único repetidor, é como ter 2 repetidores numa mesma caixa!
Tem um desempenho de áudio melhorado, uma utilização mais eficiente do espectro radioelétrico e permite uma maior autonomia da bateria em relação ao analógico. Tem também um menor custo para as Associações em comparação com outros modos de voz digital de amador.
É possível estar interligado a mais de 1600 outros repetidores DMR em todo o mundo.
O DMR é, portanto o mais recente protocolo digital para radioamador. Os rádios DMR são produzidos por vários fabricantes e todos funcionam em sistema TRBO enquanto compatíveis com Tier II, como ocorre na sua grande maioria. O DMR não é compatível com a tecnologia DSTAR da ICOM ou de outros fabricantes. A concorrência entre fabricantes é uma das grandes razões pelo qual os preços dos equipamentos DMR tendem a decrescer. O DMR está para ficar, uma vez que não é tecnologia de um fabricante, como por exemplo, o Fusion da Yaesu.
