We would like to introduce a case study on the implementation of the IP transceiver "IP510H (Dual SIM)" in the construction industry. Before the implementation, there were often physical barriers to signal reception due to the radio environment and work conditions, necessitating movement to areas with communication capability or the need for a relay, which was inefficient. Additionally, we were searching for a new emergency communication service to replace MCA radio. Considering the need for an MCA alternative and communication in areas with poor signal conditions, we proposed this product. As a result of the implementation, communication became possible even in areas that were previously dead zones for regular IP radios and mobile phones. 【Challenges Faced by the Customer】 ■ Inability to communicate on-site using phones or simple radios ■ The MCA radio service will end in 2029, leaving no emergency communication means between the headquarters and the site *For more details, please download the PDF or feel free to contact us.

Recently, large-scale typhoons and heavy rains have been occurring continuously every year, causing significant damage. In this article, we will introduce a hybrid IP transceiver (IP700PLUS) that utilizes mobile lines for wide-area communication and a unique communication network as a digital simple radio as a BCP measure. In Japan, natural disasters caused not only by earthquakes but also by typhoons and strong winds occur every year. Recently, power outages and damage to communication infrastructure have been frequent due to intensifying typhoons. *For more details on the column, please refer to the PDF. Feel free to contact us for more information.

We would like to introduce a case where the general-purpose business radio "IC-DV60S1" was implemented for an urban circular ropeway. To realize the ropeway in the Yokohama Minato Mirai area, the installation of aerial tramway radio equipment was essential, but the allocation of frequencies for business radios is limited. Unlike IP radios, using general-purpose business radios allows for communication to be possible even during earthquakes and disasters, as each communication device can serve as a starting point, thus creating a suitable communication environment for the urban ropeway. 【Case Overview】 ■Challenges - It was necessary to accurately communicate with the aerial tramway radio installed in each gondola during accidents or malfunctions and to facilitate communication with passengers who were not accustomed to radio operations. ■Results - By storing the radio in a dedicated box, theft prevention of the radio was achieved, and daily retrieval of the radio became easier. *For more details, please refer to the PDF document or feel free to contact us.
