NEC Corporation has developed a Device-to-Device communication technology, which will enable emergency response personnel to transmit images even when they are outside the service area of the public safety Long Term Evolution (PS-LTE) network.
"By utilising this technology, images from large-scale disasters and major accidents can be transmitted via a high-speed LTE network, even when outside of the public safety LTE service area. This makes it possible to obtain accurate information from the scene and to implement a swift response," said Yuichi Nakamura, General Manager for System Platform Research Laboratories in NEC Corporation. "We believe this technology can contribute substantially to the development of secure and safe infrastructure that reliably supports society."
The technology was developed as part of the "Research and Development of Device-to-Device Communication Technology for High-reliability, Low-latency Network" programme of the Ministry of Internal Affairs and Communications of Tokyo, Japan.
The transmission of images was supported through enabling terminals outside of the PS-LTE network service area to detect terminals within the service area thus access the network through a terminal that provides the fastest communication with base stations.
NEC has tested the technology in a simulated disaster relief scenario where approximately 90 percent of terminals located indoors - which tend to fall outside of the service area - achieved communications sufficient for image transmission.
