Introdução
Requisitos do Sistema
1. Proporcionar uma solução em comunicações rádio
digital às Forças Armadas, similar aos sistemas móveis
digitais civis, sendo no entanto mais adequados aos
requisitos militares.
2. A característica principal é a capacidade de desdobrar
uma rede troncalizada de forma rápida no cenário
operacional.
