[Case Study of Radio Equipment] Urban Circular Ropeway *Facility Management & BCP Measures

[Case Study of Radio Equipment] Urban Circular Ropeway *Facility Management & BCP Measures

A case where BPC measures are combined and running costs are not required! Management of communication equipment has become easier.

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.

What is an IP radio? An introduction to the communication mechanism, recommended models, and usage scenarios.

If you are considering the introduction of IP radios, please use this as a reference!

IP radios are wireless devices that use mobile phone communication networks or internet connections to make calls. Unlike conventional radios, they do not require a license or registration, making them easy to use. Additionally, they allow for nationwide communication in Japan, and since the call charges are flat-rate, costs can be kept low. This page will explain the communication mechanism of IP radios, their types, advantages, disadvantages, recommended models, and usage examples. *For detailed content of the article, please refer to the related links. For more information, feel free to contact us.*

[Wireless Equipment Rental Case] Video Production, Filming *Achieving Cost Reduction

[Wireless Equipment Rental Case] Video Production, Filming *Achieving Cost Reduction

You can use two carriers with one device! Here’s a suitable example for cost-cutting.

We would like to introduce a case study of the IP wireless device "IP502H (Dual SIM)." Previously, IP wireless devices used mobile phone networks for communication, making prior radio wave surveys essential. We would conduct on-site surveys or check coverage area maps from various carriers, which was a cumbersome task. As a result of the introduction, we can now equip the device with SIM cards from two carriers, eliminating the need for on-site radio wave surveys and ensuring more reliable communication. [Challenges] ■ It is cumbersome to check the carrier each time when using the IP wireless device. ■ The number of units required varies greatly from site to site. ■ We want to keep running costs low. *For more details, please download the PDF or feel free to contact us.
