A comunicação sem fio de alta frequência está chamando a atenção devido ao seu potencial para concretizar uma enorme capacidade de transmissão no sistema sem fio da próxima geração. O uso de bandas de alta frequência requer uma implantação densa de pontos de acesso para compensar a atenuação significativa da distância e a perda de difração. A implantação densa de pontos de acesso em um ambiente de mobilidade desencadeia um aumento na frequência de transferência porque o número de pontos de acesso candidatos aumenta. Portanto, são necessários esquemas de transferência simples. Os sistemas sem fio de alta frequência permitem que a posição da estação seja determinada usando sinais de comunicação de banda larga e altamente direcionais. Assim, é possível uma transferência simples baseada na informação de posição estimada utilizando o sinal de comunicação. As interrupções causadas pela transferência também são uma enorme barreira para a realização de comunicações sem fio estáveis de alta frequência. Este artigo propõe um esquema de handover contínuo usando múltiplas unidades de rádio. Este artigo avalia a combinação de transferência simples e o esquema proposto com base em experimentos utilizando um carro de corrida de fórmula representando o ambiente de mobilidade de alta velocidade mais rápido. Resultados experimentais mostram que a transferência perfeita e a transmissão sem fio de alta velocidade acima de 200 Mbps são alcançadas em uma área de 400 m, mesmo em velocidades de estação superiores a 200 km/h.

Abstract: High-frequency wireless communication is drawing attention because of its potential to actualize huge transmission capacity in the next generation wireless system. The use of high-frequency bands requires dense deployment of access points to compensate for significant distance attenuation and diffraction loss. Dense deployment of access points in a mobility environment triggers an increase in the frequency of handover because the number of candidate access points increases. Therefore, simple handover schemes are needed. High-frequency wireless systems enable station position to be determined using their wideband and highly directional communication signals. Thus, simple handover based on position information estimated using the communication signal is possible. Interruptions caused by handover are also a huge barrier to actualizing stable high-frequency wireless communications. This paper proposes a seamless handover scheme using multiple radio units. This paper evaluates the combination of simple handover and the proposed scheme based on experiments using a formula racing car representing the fastest high-speed mobility environment. Experimental results show that seamless handover and high-speed wireless transmission over 200Mbps are achieved over a 400-m area even at station velocities of greater than 200km/h.
