Abstract
?virtualização de ambientes de rádio naturais para testar um dispositivo de rádio? trata-se de ambientes de rádio naturais que são virtualizados para testar dispositivos de rádio. em um exemplo, isso é feito extraindo-se sinais e mensagens registradas no campo e injetando-se os mesmos na operação de um equipamento para teste de protocolo. em outro exemplo, o ambiente de rádio é reproduzido gerando-se respostas de impulso de canal em um rastreador de raio e, então, interpolando os mesmos em um emulador de canal e que suporta a interpolação por meio de pós-processamento. em outro exemplo, o ambiente de rádio é registrado com o uso de um terminal móvel no campo. em outro exemplo, ambientes de rádio naturais são produzidos reconstruindo-se cargas de célula realísticas e, como consequência, interferência intracelular para um determinado dispositivo sob teste.
